Full textAbstract:
Textile materials, due to their large surface area and moisture retention capacity, allow the growth of microorganisms, causing undesired effects on the textile and on the end-users. The textile industry employs nanomaterials (NMs)/composites and nanofibers to enhance textile features such as water/dirt-repellent, conductivity, antistatic properties, and enhanced antimicrobial properties. As a result, textiles with antimicrobial properties are an area of interest to both manufacturers and researchers. In this study, we present novel regression models that predict the antimicrobial activity of nano-textiles after several washes. Data were compiled following a literature review, and variables related to the final product, such as the experimental conditions of nano-coating (finishing technologies) and the type of fabric, the physicochemical (p-chem) properties of NMs, and exposure variables, were extracted manually. The random forest model successfully predicted the antimicrobial activity with encouraging results of up to 70% coefficient of determination. Attribute importance analysis revealed that the type of NM, shape, and method of application are the primary features affecting the antimicrobial capacity prediction. This tool helps scientists to predict the antimicrobial activity of nano-textiles based on p-chem properties and experimental conditions. In addition, the tool can be a helpful part of a wider framework, such as the prediction of products functionality embedded into a safe by design paradigm, where products’ toxicity is minimized, and functionality is maximized.

Full textAbstract:
Bark extracts are important sources of natural dyes. They possess many functional properties of potential interest to the textile industry. Currently, textiles with eco-friendly functional finishing are increasingly sought for in medical and protective clothing due to stringent environmental laws and the associated toxicity of synthetic agents. In view of this, recent studies on bark extracts for multi-functional finishing of textiles, particularly for antimicrobial and UV protective finishing, is reviewed. Bark extracts from various trees are able to effectively impart antimicrobial resistance and UV protection properties to treated fabrics; however, their long-term sustenance and strength depend on a multitude of factors. However, the application of bark extracts on several types of textile fabrics have no significant impact on textile quality.

In recent years bioactive textiles have risen to the forefront of consumers perception due to their potential protection against virus, fungi and bacteria. However, traditional textile staining is an eco-damaging process that and current methods of textile functionalization are expensive, complicated and with great environmental impact. With that in mind, this work sought to show a possible solution for this problematic through the usage of a novel one step textile dyeing and functionalization method based upon nanoencapsulated textile dyes (NTDs). To do so navy blue everzol NTDs were produced with chitosan, cotton dyed, characterized through FTIR and SEM and biological potential evaluated through biocompatibility screening and antimicrobial activity against skin pathogens. The data obtained showed that NTDs effectively dyed the target textile through a coating of the cotton fibre and that NTDs formed hydrogen bonds with the cellulose fibre via electrostatic interactions of the chitosan amino groups with cotton sulphate groups. From a biocompatibility perspective NTDs dyed cotton had no deleterious effects upon a skin cell line, as it promoted cellular metabolism of HaCat cells, while traditionally died cotton reduced it by 10%. Last but not least, NTDs dyed cotton showed significant antimicrobial activity as it reduced viable counts of MRSA, MSSA and A. baumannii between 1 and 2 log of CFU while traditional dyed cotton had no antimicrobial activity. Considering these results the novel method proposed shows is a viable and ecological alternative for the development of antimicrobial textiles with potential biomedical applications.

Full textAbstract:
Depositing nanoparticles in textiles have been a promising strategy to achieve multifunctional materials. Particularly, antimicrobial properties are highly valuable due to the emergence of new pathogens and the spread of existing ones. Several methods have been used to functionalize textile materials with gold nanoparticles (AuNPs). Therefore, this review highlighted the most used methods for AuNPs preparation and the current studies on the topic in order to obtain AuNPs with suitable properties for antimicrobial applications and minimize the environmental concerns in their production. Reporting the detailed information on the functionalization of fabrics, yarns, and fibers with AuNPs by different methods to improve the antimicrobial properties was the central objective. The studies combining AuNPs and textile materials have opened valuable opportunities to develop antimicrobial materials for health and hygiene products, as infection control and barrier material, with improved properties. Future studies are needed to amplify the antimicrobial effect of AuNPs onto textiles and minimize the concerns related to the synthesis.

Full textAbstract:
Far Infrared (FIR) functionalized textile materials are enjoying a special attention nowadays, as a viable and practical solution for treating a wide range of medical conditions (relief of acute or chronic inflammation and circulatory problems, prevention of microbial infections, improvement of nervous system functions, reduction of skin lipids, improvement of blood circulation, removal of accumulated toxins by improving lymphatic circulation etc.). At the molecular level, FIR compounds and functionalized materials exert strong rotational and vibrational effects, with beneficial biological potential. These materials are based on the principle of absorbing light energy and then irradiating this energy back into the body at specific wavelengths. FIR functionalized textile materials are a new category of functional textiles that have the potential to improve well-being and health. Present paper explored the antimicrobial potential of four textile materials, functionalized with FIR, UV protection and antimicrobial functionalization compounds, tested according to two methods for assessment of antimicrobial character: a testing method in dynamic conditions and a testing method in static conditions. The evaluation of the antimicrobial character showed very good rates of reduction of the microbial population, of the functionalized textile materials, following the testing on four strains of pathogenic fungi: Candida albicans, Epydermophyton floccosum, Tricophyton interdigitale and Aspergillus niger, with reduction rates between 76.16% and 96.06%.

Full textAbstract:
In a hospital environment, textile substrates have been implicated as a vector in the transmission of disease. To mitigate the harmful spread of disease via textile substrates, an effective measure is treatment of textiles with antimicrobial agents. The current investigation compares one of the most widely used chemically synthesized antimicrobial agents, triclosan with chitosan, a naturally occurring antimicrobial agent. For the study, samples of a common polyester/cotton textile used in hospital settings were treated with triclosan and chitosan based antimicrobial agents. Following treatment, the samples were analyzed for their effectiveness against Staphylococcus aureus and Escherichia coli using standard AATCC Test Methods. The efficacy of the treatment to laundering was then evaluated by subjecting the treated samples to 50 washings and repeating the tests against the challenge microorganisms. Data obtained were statistically analyzed at a 95% confidence interval. Results showed that before laundering both triclosan and chitosan treated samples were extremely effective as antimicrobial agents. After laundering, chitosan was less effective against E.coli but maintained efficacy against S. aureus. The effectiveness of triclosan was not adversely affected after the laundering treatments.

The control of microbial proliferation is a constant battle, especially in the medical field where surfaces, equipment, and textiles need to be cleaned on a daily basis. Silver nanoparticles (AgNPs) possess well-documented antimicrobial properties and by combining them with a physical matrix, they can be applied to various surfaces to limit microbial contamination. With this in mind, a rapid and easy way to implement a photoinduced approach was investigated for textile functionalization with a silver@polymer self-assembled nanocomposite. By exposing the photosensitive formulation containing a silver precursor, a photoinitiator, and acrylic monomers to a UV source, highly reflective metallic coatings were obtained directly on the textile support. After assessing their optical and mechanical properties, the antimicrobial properties of the functionalized textiles were tested against Escherichia coli (E. coli) and Candida albicans (C. albicans) strains. In addition to being flexible and adherent to the textile substrates, the nanocomposites exhibited remarkable microbial growth inhibitory effects.

In the past two decades, a growing body of research regarding the utilization of natural bacterial pigments or dyes for textile dyeing has emerged. Bacterial pigments are bacterial secondary metabolites that usually have bright colors and some special properties (e.g., antimicrobial, antioxidative, UV protective etc.). In addition to their high production yield, these special properties led scientists to research and develop methods for utilizing bacterial pigments in textile dyeing. This study presents the current state this field of research, with a focus on the dyeing potential of bacterial pigments for different types of textile material. The potential future directions of research in this area are also highlighted. In addition to the durable dyeing of textiles, bacterial pigments with special properties, such as antimicrobial activity, can add multifunctionality to dyed materials, thus increasing the value of the final product. This emerging field of research will also have a great impact on sustainability and the environment, contributing to the decreased usage of synthetic dyes in the textile industry.

The main drawback with microorganism's development on fabrics is associated with the maintenance of hygiene and fabric deterioration. In this present investigation a trial has been made to produce an attractive and vibrant textile with eco-friendly antimicrobial dyeing by marigold, a natural resource. Tagetes erecta universally recognized as Marigold is a remarkable source of carotenoids and lutein, grown as a lawn plant. Now a day, lutein is exploding into an indubitably predominant active fitting, employed as an element of the Drugs, Nutrients and Textile Industry. The prospective application of marigold as a characteristic of antimicrobial activity has not been accustomed fully. It is due to the lack of knowledge about its ability and resemblance in material manner. In this work, we have concentrated on the analysis, which was led to deliberate the use of distillate isolate of marigold as an antimicrobial. The antimicrobial competence of the extract was evaluated by coloring on cotton textiles. Testing of the dye ability, its wash quickness and light fastness was done. Educations have validated that antimicrobial coatings have not affected by laundering and shown enhanced colouring effect comprising of fastness to washing, perspiration and rubbing than conservatively dyed textiles. It revealed that the essence of Marigold flower is habitually employed for cotton fabrics as an antimicrobial finish. The samples show very encouraging ends up in terms of antimicrobial resistivity.

The article analyzes the existing methods of imparting antimicrobial properties to textile materials and assesses their effectiveness. The purposeof the work. Production of woolen materials with antimicrobial properties. Methodology.The work uses scientific, logical, objective research methods. Results and discussion.Technologies for obtaining antimicrobial woolen materials have been developed. Studies have been conducted on the influence of the proposed compositions on the coefficient of resistance to microbiological destruction of woolen materials. It was found that the antimicrobial effect in all compositions is achieved at a minimumconcentration of polyhexamethyleneguanidine hydrochloride, more than 80%. Studies on the resistance of antimicrobial properties of modified samples to repeated washings have shown that the coefficient of resistance to microbiological destruction is reduced by 10-16%. It follows that the proposed formulations have a residual antimicrobial effect. The influence of the developed compositions on the physico-chemical and physico-mechanical properties of textile materials has been studied. The properties and structure of the objects of research are studied, and the mechanism of interaction of the components used is investigated. Parameters of application and heat treatment, the optimal modes of the technological process of finishing textile materials have been established. Conclusions.The developed technology provides antimicrobial activity of textile material while maintaining the hygienic and operational properties of woolen materials. Studies have shown that modified woolen textile materials acquire antimicrobial properties, and are not destroyed by microorganisms under operating conditions, and the quality indicators of textile materials do not deteriorate after processing.

Healthcare workers in the hospital environment are at risk of infection and body fluids such as saliva, bacterial contamination, oral bacteria, etc. directly or indirectly exacerbate this issue. These bio-contaminants, when adhered to hospital linens and clothing, grow substantially, as conventional textile products provide a favorable medium for bacterial and viral growth, adding to the risk of transmitting infectious diseases in the hospital environment. Textiles with durable antimicrobial properties prevent microbial colonization on their surfaces and help contain the spread of pathogens. This longitudinal study aimed to investigate the antimicrobial performance of PHMB-treated healthcare uniforms during prolonged usage and repetitive laundry cycles in a hospital environment. The PHMB-treated healthcare uniforms displayed non-specific antimicrobial properties and remained efficient (>99% against S. aureus and K. pneumoniae) after use for 5 months. With the fact that no antimicrobial resistance was reported towards PHMB, the presented PHMB-treated uniform may reduce infection in hospital settings by minimizing the acquisition, retention, and transmission of infectious diseases on textile products.

The incorporation of MNPs in textiles allows for the obtention of multifunctional properties, such as ultraviolet (UV) protection, self-cleaning, and electrical conductivity, as well as antimicrobial, antistatic, antiwrinkle, and flame retardant properties, without compromising the inherent characteristics of the textile. Environmental sustainability is also one of the main motivations in development and innovation in the textile industry. Thus, the synthesis of MNPs using ecofriendly sources, such as polysaccharides, is of high importance. The main functions of polysaccharides in these processes are the reduction and stabilization of MNPs, as well as the adhesion of MNPs onto fabrics. This review covers the major research attempts to obtain textiles with different functional properties using polysaccharides and MNPs. The main polysaccharides reported include chitosan, alginate, starch, cyclodextrins, and cellulose, with silver, zinc, copper, and titanium being the most explored MNPs. The potential applications of these functionalized textiles are also reported, and they include healthcare (wound dressing, drug release), protection (antimicrobial activity, UV protection, flame retardant), and environmental remediation (catalysts).

The development of textile finishing with improved functional properties has been a growing interest among industry and scientists worldwide. The recent global pandemic also enhanced the awareness amongst many toward improved hygiene and the use of antimicrobial textiles. Generally, natural herbal components are known to possess antimicrobial properties which are green and eco-friendly. This research reports a novel and innovative method of developing and optimising nano-emulsions using two combinations of herbal extracts produced from Moringa Oleifera, curry leaf, coconut oil (nano-emulsion 1) and other using Aegle marmelos with curry leaf and coconut oil (nano-emulsion 2). Nano-emulsions were optimised for their pH, thermal stability, and particle size, and percentage add-on. Organic cotton fabrics (20 and 60 gsm) were finished with nano-emulsions using continuous and batch processes and characterised for their surface morphology using scanning electron microscopy, energy dispersive X-ray (EDX) analysis and Fourier transform infrared spectroscopy (FTIR) analysis. The finished fabrics were evaluated for their Whiteness Index, assessed for antimicrobial resistance against Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli) using AATCC 100 and 147 methods. In addition, fabrics were assessed for their antifungal efficacy (AATCC 30), tensile strength and air permeability. Results suggested that finished organic fabrics with nano-emulsions had antimicrobial resistance, antifungal, wash fastness after 20 washing cycles, and sufficient strength. This novel finishing method suggests that organic cotton fabrics treated with nano-emulsions can be used as a durable antimicrobial textile for healthcare and hygiene textiles.

Microbiological protection textile materials played an important role in the battle against the epidemic. However, the traditional active antimicrobial treatment of textiles suffers from narrow textile applicability, low chemical stability, and poor washability. Here, a high-strength adhesive nanosilver glue was synthesized by introducing nontoxic water-soluble polyurethane glue as a protectant. The as-prepared nanosilver glue could adhere firmly to the fiber surfaces by forming a flexible polymer film and could encapsulate nanosilver inside the glue. The as-prepared nanosilver had a torispherical structure with diameter of ~22 nm, zeta potential of −42.7 mV, and good dispersibility in water, and it could be stored for one year. Further studies indicated that the nanosilver glue had wide applicability to the main fabric species, such as cotton and polyester fabric, surgical mask, latex paint, and wood paint. The antimicrobial cotton and polyester fabrics were prepared by a simple impregnation–padding–baking process. The corresponding antimicrobial activity was positively correlated with nanosilver content. The treated fabrics (500 mg/kg) exhibited ultrahigh washing resistance (maintained over 99% antibacterial rates for 100 times of standard washing) and wear resistance (99% antibacterial rates for 8000 times of standard wearing), equivalent breathability to untreated fabric, improved mechanical properties, and good flexibility, demonstrating a potential in cleanable and reusable microbiological protection textiles.

An improper indoor microclimate has adverse effects on the state of preservation of historical textiles arranged in them, favoring the development of bacteriological microflora. The current study aims to combine traditional and innovative methods for cleaning and preserving a 100-year-old traditional blouse from Bihor, Romania. The material of the blouse was impregnated with 30 and 70 ppm silver nanosuspensions and washed with a substance obtained from boiling natural wood ash (lye). The research goals were to determine the antimicrobial action of lye washing and silver nanoparticles applied to the analyzed textile material and identify the way in which the environmental factors (light) act upon the conservation degree of textile objects impregnated with silver nanoparticles. All these procedures are eco-friendly and do not cause any damage to the constituent material of the fabrics. The use of the hyperspectral imaging technique proved the permeation of both 30 and 70 ppm silver nanosuspensions into the textile, producing changes in the textile’s reflectance spectrum after being treated with them. The results showed anti-bactericidal/fungal properties of both silver nanoparticles and lye. Microbiological analyses revealed that bacterial colonies were reduced to more than 95% in both cases. The antibacterial effect of silver nanoparticles on the textile material of the blouse was maintained throughout the duration of the study, and under normal environmental conditions, the effects would remain active for a long period.

Antimicrobial properties are gaining popularity and getting more attention in the textile industry. Also, the demand for antimicrobial products has increased significantly in the market because consumers are demanding fresh and clean clothes. Various chemical agents are used in industries to give an antimicrobial finish to textiles. These chemicals are long-lasting and highly effective against various bacteria, microbes and fungi, but those chemicals are harmful to the environment. Therefore, much of the research has been conducted on medicinal plant based antimicrobial agents. Natural antimicrobial compounds have less harmful impacts on living beings and are also more environmentally friendly. Various medicinal plants that contain antimicrobial compounds are present and these plants are used as home medicines for various diseases. Such plants are neem (Azadirachta indica), basil (Ocimum basilicum), pomegranate (Punica granatum), Arjun tree (Terminalia arjuna), sage plant (Salvia officinalis) etc. This study is conducted systematically by considering only evergreen herbal medicinal plants of the Indian subcontinent. Medicinal plants were utilized to impart antimicrobial properties to textiles and to develop various products.

Synthesis and characterization of pyridyl-thienyl acetohydrazide derivative (AHZ) using NMR (13C and 1H) and FTIR. Modification of cotton fabric (CF) with acetohydrazide (AHZ) and metal chlorides of divalent Cr, Mn, Co, Ni, Cu, and Zn and trivalent Fe, and Cr. SEM-EDX and Fourier-transform infrared were utilized to characterize cellulose-based cotton fabric (CF) attached to AHZ and their metal (M) complexes. Antimicrobial activity was examined against two types of bacteria, namely S. aureus and E. coli, and two types of fungi, namely C. albicans and A. flavus. All modified samples exhibited higher efficiency towards bacterial strains than fungal strains. In addition, cellulose modified with Ni (II) confers the most antibacterial protection efficiency.

Full textAbstract:
The review provides an overview of research findings on microencapsulation for functional textile coatings. Methods for the preparation of microcapsules in textiles include in situ and interfacial polymerization, simple and complex coacervation, molecular inclusion and solvent evaporation from emulsions. Binders play a crucial role in coating formulations. Acrylic and polyurethane binders are commonly used in textile finishing, while organic acids and catalysts can be used for chemical grafting as crosslinkers between microcapsules and cotton fibres. Most of the conventional coating processes can be used for microcapsule-containing coatings, provided that the properties of the microcapsules are appropriate. There are standardised test methods available to evaluate the characteristics and washfastness of coated textiles. Among the functional textiles, the field of environmentally friendly biodegradable textiles with microcapsules is still at an early stage of development. So far, some physicochemical and physical microencapsulation methods using natural polymers or biodegradable synthetic polymers have been applied to produce environmentally friendly antimicrobial, anti-inflammatory or fragranced textiles. Standardised test methods for evaluating the biodegradability of textile materials are available. The stability of biodegradable microcapsules and the durability of coatings during the use and care of textiles still present several challenges that offer many opportunities for further research.

In this research, a textile surface was modified by the sol–gel methodology with a new antimicrobial coating containing nanoparticles active against bacteria resistant to antibiotics. The effect of ultrasonic irradiation power (40 to 90 kHz), the concentration of reagents (nanoparticles, precursor and acids) and time (15 to 72 min) were investigated in relation to the structure, morphology and antimicrobial activity of coatings with zinc oxide nanoparticles. The relationship between the sonocatalytic performance and structure of the resultant modification was established by using various techniques, such as FTIR spectroscopy (FTIR) and scanning electron microscopy with an EDX detector (SEM-EDX), thin-layer chromatography (TLC) and antimicrobial effects were determined on selected model microorganisms. The homogeneity of layers with ZnO nanoparticles on samples was increased by increasing the ultrasonic irradiation power and time. The ultrasonic irradiation unify did not only unify both the structure and the morphology of samples, it also prevented the agglomeration of the nanoparticles. Moreover, under optimal conditions, an antimicrobial coating with ZnO nanoparticles, active against bacterial species S. aureus and E. coli was efficiently prepared. Results of the Time-kill methodology revieled excellent results starting after 6 hours of exposal to antimicrobialy functionalized cellulose polymer.

Particularly, the treatment of synthetic dyes, which are found abundantly amounts in textile wastewater, has gained importance. Recent studies have focused on the use of biological treatment technologies to remove pollutants in water. On the other hand, the disposal of wastes from biological treatment technologies was considered as another environmental problem. This study aims to compare the antimicrobial properties of the extract obtained from dye loaded and un-loaded lichen biomass after the biosorption process. According to the results of this study, it was found that the extract obtained from the waste lichen biomass, which has loaded with the textile dye in the decolorization process, showed a similar antimicrobial effect with the unloaded lichen extract. To sum up the waste lichen biomass used to remove textile dyes can be reused for the application of antimicrobial products.

Nanoparticles are increasingly utilized as coating materials to improve the properties of polyester textiles. In this work, polyester textiles were successfully fabricated, with hydrazide groups serving as ligands for the entrapment of sliver ions and subsequent reduction to AgNPs. Polydopamine (PDA) was used in this work to impart antibacterial and antioxidant properties to the polyester textiles through its phenolic hydroxyl groups, which can convert silver ions into AgNPs. Moreover, glucose was used as a reducing agent to create AgNPs-loaded polyester hydrazide. ATR-FTIR, SEM, EDX, thermogravimetric analysis (TGA), and tensile strength were used to characterize the pristine polyester, the polyester hydrazide, the PDA-coated AgNP-loaded polyester hydrazide and the AgNP-loaded polyester hydrazide. A broth test was also used to investigate the textile’s antimicrobial activities against Escherichia coli and Staphylococcus aureus. Overall, the composite nanocoating with PDA-AgNPs demonstrated good tensile strength and antioxidant and antibacterial characteristics, implying the practicality of PDA-AgNPs coating polyester for biomedical textile applications.

Healthcare-associated infections are of global concern, and textiles can contribute to the transmission of pathogens. In this study, we examined quantitatively the survival capability of 60 multidrug-resistant bacterial strains from four species ( Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus and Enterococcus faecium) on untreated cotton textile in clinically relevant incubation periods. We determined the antibacterial efficiency of textiles treated either with quaternary ammonium compound (QAC)-containing Sanitized T99-19 liquid (50 m/m% Dimethyltetradecyl (3-(trimethoxysilyl)propyl) ammonium-chloride) or with silver salt-containing Sanitized T27-22 Silver liquid (2 m/m% AgCl and 8 m/m% TiO2) as well. Finally, we compared the results of the healthcare-associated, multidrug-resistant strains and antibiotic-sensitive, quality control standard strains (ATCC 25922, ATCC 11105 Escherichia coli, and ATCC 25923, ATCC 6538 Staphylococcus aureus) often used in antimicrobial efficiency tests. The results revealed that all investigated multidrug-resistant bacteria are able to survive on untreated cotton textile and pose health risk in hospitals. During one day the T27-22-Silver-treated textile was able to eliminate most of the Gram-positive pathogens, reducing the risk of cross-contamination, but none of the examined agents destroyed the multidrug-resistant, Gram-negative isolates. The antibiotic-susceptible and the multidrug-resistant Staphylococcus aureus strains had similar survival capability and biocide-tolerance, while the risk of infections caused by multidrug-resistant, Gram-negative pathogens could be extremely underestimated using only ATCC Escherichia coli standard strains. Our results also draw attention to the careful evaluation of antimicrobial efficiency tests and indicate that a significant reduction of bacterial count does not necessarily mean significant antibacterial efficiency that would be suitable to avoid infections.

Full textAbstract:
Polyurethane (PU) coatings are often applied on high added value technical textiles. Key factor to success of PU coatings is its versatility and durability. Up to today most PU textile coatings are solvent-based or water-based. Recent advances are made in applying bio-based PU on textiles. Currently, polymers made from renewable raw materials are experiencing a renaissance, owing to the trend to reduce CO2 emissions, the switch to CO2-neutral renewable products and the depletion of fossil resources. However, the application of bio-based coatings on textiles is limited. The present paper discusses the potential of a bio-based anionic PU dispersion as an environment friendly alternative for petroleum-based PU in textile coating. Coatings were applied on textile via knife over roll. The chemical, thermal and mechanical properties of the bio-based PU coating were characterised via FT-IR, thermogravimetric analysis, differential scanning calorimetry and tensile test. The performance of the coating was studied by evaluating antimicrobial properties, fire retardancy, the resistance to hydrostatic pressure initially and after washing, QUV ageing and hydrolysis test. The developed bio-based PUD coating complied to the fire retardancy test ISO 15025 and exhibited excellent hydrostatic pressure, QUV ageing resistance, hydrolysis resistance, wash fastness at 40 °C.

Materials exhibiting an antimicrobial effect are especially advantageous for medical textiles which are in very close and long-term contact with human skin. Orthopaedic stockings made of terry cotton and polyamide were coated with silver nanoparticles by a simple dip coating process under mild conditions. Both textiles released silver ions over at least 28 days. The silver ion release for both materials is governed by diffusion. The amount of silver ions released by the cotton textile was higher than by the nylon stockings by about a factor of 4. The reason was a larger silver reservoir in the cotton sample, because it contains much more silver than the nylon fabric. As expected from the results of the Ag+ release tests, both these silver coated textiles were active against Escherichia coli.

Purpose This work aims to synthesize a series of novel acyclic and/or heterocyclic systems, as precursors for dyes with potential antimicrobial activity that could be used for simultaneous dyeing and antimicrobial textile finishing. Thus, a series of novel pyridine, thiophene and pyrazolo[3,4-b]pyridine derivatives were synthesized, and their antimicrobial and textile finishing properties were studied and evaluated. Design/methodology/approach The synthesis, structure elucidation and antimicrobial activities of the newly synthesized compounds based on 4,4-dicyano-3-phenyl-but-3-enoic acid phenylamide (1) were demonstrated. The minimal inhibitory concentration in μg/mL of the compounds showed significant antimicrobial activity against most of the tested organisms. On the other hand, their spectral characteristics and fastness properties were measured and evaluated. Antimicrobial activities of the dyed fabrics in terms of inhibition zones (mm) were measured and evaluated. Findings A series of novel heterocyclic compounds (Schemes 1-3) were synthesized based on starting material (1). Compounds (1), 2, 4a, 8a and 9c exhibited comparable or even higher antibacterial activities than the selected standards (ampicillin), while compounds 2, 3c, 3d, 4a and 8b revealed higher antifungal activities than the selected standard (cycloheximide). On the other hand, some dyes showed high antimicrobial evaluation on the dyed fabrics (nylon 66, acetate and polyester) expressed as size (mm) of inhibition zones (Tables I-IV). Practical implications Results revealed that many hydrazo and azo derivatives were synthesized from some pyridines and thiophenes. The antimicrobial evaluation and textile finishing of the newly synthesized products revealed significant and potent values of antimicrobial activity. Originality/value All the synthesized compounds were novel and most of them exhibited higher antimicrobial activities than the selected standards antibiotics, thus are valuable for simultaneous dyeing and antimicrobial functional finishing of textile fabrics.

The purpose of the work is to develop an antimicrobial composition and study the effectiveness of antimicrobial treatment of textile materials. Methodology. Polyhexamethylene guanidine chloride with bio-based antimicrobial preparations were used as the objects of the study as effective safe antimicrobial agents. The treatment of cotton fabric was carried out by impregnation with an aqueous solution of polymer and polyhexamethylene guanidine chloride and bio-based antimicrobial preparations in a finishing bath, followed by drying and thermal fixation. Changes in the structural parameters of the acrylic polymer and the number of crosslinks in the bulk of the polymer formation were determined from the property of crosslinked polymer systems to swell in solvents to a limited extent. Examination of the antimicrobial effect of textile materials was carried out by analyzing the diffusion of the fabric disk on agar after treatment with the antimicrobial composition and after washing. To determine the effectiveness of the antimicrobial action of bio-based preparations, one of the representatives of the wound microflora, the gram-positive bacterium Staphylococcus pyoqenes from the Ukrainian collection of microorganisms, was used as a test culture. Findings. The results of the study of textile materials after treatment with bio-based antimicrobial preparations and polyhexamethylene guanidine chloride are presented. An increase in the resistance of the antimicrobial effect to washing was achieved by introducing an acrylic polymer into the finishing composition, the structure formation of which was evaluated by the amount of the acetone-insoluble fraction of polymer films during extraction in solvents. The results of the study showed that the introduction of antimicrobial agents into the polymer composition increases the degree of crosslinking of the polymer film due to the use of polyhexamethylene guanidine chloride. The effectiveness of the antimicrobial action of bio-based preparations has been proven by the results of a study on a test culture of a gram-positive bacterium Staphylococcus pyoqenes, which is confirmed by the appearance of a zone of inhibition of the microorganism around the studied fabric sample. Studies using the settle plate method showed that all fabric samples treated with the antibacterial composition are characterized by a pronounced zone of microflora growth inhibition. Originality. It has been proven that an acrylic polymer-based finishing composition containing polyhexamethylene guanidine chloride and bio-based preparations provides an antimicrobial effect to a textile material and will improve the wash resistance of the antimicrobial effect by increasing the degree of crosslinking of the acrylic polymer. Practical value. The obtained results of the experiment are of practical importance for the development of new finishing compositions for imparting antimicrobial properties to textile materials.

The central idea of the present research aims at achieving textile substrates through an efficient inclusion of a wild black cherry extract into the grafting agent-monochlorotriazinyl-β-cyclodextrin (MCT-β-CD). The methodology consists in a permanent/irreversible entrapment onto the fibres surface of the natural extract through inclusion mechanism. Exhaustion and sonication dyeing procedures were used alternatively. The obtained materials were characterized, by FT-IR and BET analysis. The experimental results reveal good adsorptive feature of the samples, due to a higher specific surface created by the inclusion complex (MCT-β-CD-dye pigment). An efficient blocking of the natural dye pigment molecules into the grafting agent’s cavity (MCT-β-CD), assumed both a stable dyeing and antimicrobial potential. The results obtained by this ecologic surface grafting method will contribute to novel key points in producing healthy natural textiles, as alternatives for single use textiles. The results provided by this research will be used as starting point for a future study targeting the obtaining of textile supports with antimicrobial performance. Other investigations like washing, rubbing and colour fastness, highlighted that dyeing treatment by sonication is extremely efficient and could be successfully applied to such items, in boosting developments.

Introduction. In recent years, there has been a constant search for more advanced and environmentally friendlymeans for antimicrobial treatment of cellulose-containing tissues of various intended uses in the textile industry.Problem Statement. The problem of protection of textile materials and products from microbiological destruction is complex and multifaceted and needs to be solved. Today, one of the methods of protection is to provide textile materials with biocidal properties, which not only prevents the growth of bacteria, but can also ensure a high level of tissue safety. Therefore, we are faced with the task of finding new safe biocidal products.Purpose. The research has been made to determine the level of safety of textile materials treated by biocidalsubstances with the thiosulfonate structure including Ethylthiosulfanilate, Methylthiosulfanilate and Allylthiosulfanilate.Materials and Methods. The fabrics of different chemical composition were used in the study, designed for themanufacture of overalls. New preparations of thiosulfonate structure were chosen for impregnation: ethylthiosulfanilate (ETS), methylthiosulfanilate (MTS) and allylthiosulfanilate (ATS). The presence of heavy metals and pesticides was determined by atomic absorption spectrometry with the use of a ZEENIT 650P spectrometer (Germany).Results. It has been established that the detected level of heavy metals and pesticides in the studied textile materials is insignificant and is within the regulatory requirements. It has been confirmed that the studied biocidal substances are low-toxic and environmentally friendly, because before and after treatment they did not change the hygienic parameters of tissues. A method for imparting biocidal properties to textile materials for the manufacture of overalls, in particular by impregnating textile materials with an alcoholic solution of biocidal products, has been developed. Also due to this treatment, the water absorption of materials decreases by an average of 40%.Conclusions. The treatment of textile materials with biocidal preparations of the thiosulfonate structure allowsobtaining simultaneously two desired effects for these fabrics: the appropriate bioresistance and water resistance.

Full textAbstract:
The functionalization of antibacterial drugs is one of the important areas of research in the textile industry. It uses traditional antimicrobial agents of synthetic or natural origin, and generates new biopolymers with useful properties. Some of them, such as lignin and pectin, have good biocompatibility, antioxidant and antimicrobial properties, but the domestic market uses them mainly in the construction and food industries, respectively. The antimicrobial activity of sodium lignosulfonate, apple pectin and their mixture against gram-positive bacteria (Staphylococus aureus) and gram-negative strains (Escherichia coli, Pseudomonas aeruginosa) was studied. Experimental results have shown that lignin exhibits slightly higher antibacterial activity compared to pectin and is more effective against Staphylococcus aureus in terms of minimal bactericidal and minimal inhibitory concentrations. Determination of cytotoxicity of sodium lignosulfonate by MTT showed the non-toxicity of this biocide for human cells. It was found that the antimicrobial behavior of lignosulfonates, pectins and their mixtures differs in relation to gram-positive and gram-negative strains of bacteria. It appeared that the most vulnerable to bactericides are gram-positive strains of Staphylococcus aureus due to the possible absence of double-membrane wall cells. In addition, the simultaneous use of lignin and pectin as a synergistic mixture showed an increase in antibacterial action against all microorganisms by 2-4 times. The antimicrobial effect of the studied biocides was compared to the traditional antimicrobial drug argent nitrate, which is widely used in various industries, including textile production. It was found that lignin and pectin in amounts of 1-5 мг/см3 have the same antimicrobial effect for gram-positive strains and 10-20 мг/cм3 – for gram-negative bacteria, as a solution of AgNO3 with a concentration of 0.2 мг/см3. Higher concentrations of lignin and pectin can be offset by significantly lower prices compared to argentum salts, as well as greater environmental and medical safety for human health. In addition, lignin is potentially available in large quantities as a by-product from the pulp industry and lignocellulosic bioprocessing plants. This piece of work may be useful in future when creating antimicrobial compositions for textiles.

The skin microbiome has become a hot field of research in the last few years. The emergence of next-generation sequencing has given unprecedented insights into the impact and involvement of microbiota in skin conditions. More and more cosmetics contain probiotics or bacteria as an active ingredient, with or without scientific data. This research is also acknowledged by the textile industry. There has been a more holistic approach on how the skin and textile microbiome interacts and how they influence the pH, moisture content and odour generation. To date, most of the ingredients have a broad-spectrum antibacterial action. This manuscript covers the current research and industry developments in the field of skin and textiles. It explores the nature of antimicrobial finishing in textiles which can disrupt the skin microbiome, and the benefits of more natural and microbiome friendly therapies to combat skin conditions, malodour and skin infection.
