Streszczenie:

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.

Streszczenie:

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.

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.

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%.

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 need to develop new materials for a variety of applications is greatly promoting academic and industrial research. In this thesis work antimicrobial textiles were prepared. To contribute to this topic, we started a research program that heavily relies on our expertise in the field of antibacterial peptides. Among the many polymeric materials available, cellulose fibers are particularly attractive, being naturally occurring, and easy to functionalize. Peptides and dendrimers were immobilized, as antimicrobial agent, onto cotton fabrics. Preparation of immobilized peptide-cotton materials was obtained using different innovative synthetic methods. Characterization analysis by FT-IR, XPS, UV-Vis, TGA and EPR was also performed for qualitative and quantitative determination of cotton functionalization. Moreover, enzymatic degradation was carried out allowing the application of NMR spectroscopy in solution. Antimicrobial activity of samples were tested against Staphylococcus aureus (Gram positive bacteria) and Escherichia coli (Gram negative bacteria). Promising results were obtained against the Gram positive strain, while only few samples show good activity against Gram negative bacteria.
La necessità di sviluppare nuovi materiali per una varietà di applicazioni sta interessando fortemente la ricerca accademica e industriale. In questo lavoro di tesi sono stati preparati dei tessuti antimicrobici. Per contribuire a questo argomento, abbiamo avviato un programma di ricerca che si basa sulla nostra esperienza nel campo dei peptidi antibatterici. Peptidi e dendrimeri sono stati immobilizzati, come agenti antimicrobici, su tessuti. Tra i molti materiali polimerici disponibili, le fibre di cellulosa sono particolarmente attraenti, essendo esse presenti in natura e facile da funzionalizzare. Caratterizzazioni FT-IR, XPS, UV-Vis, TGA e EPR sono state effettuate per la determinazione qualitativa e quantitativa della funzionalizzazione del cotone. Inoltre, la degradazione enzimatica ha consentito l'applicazione della spettroscopia 1H-NMR in soluzione. L'attività antimicrobica dei campioni è stata testata contro lo Staphylococcus aureus (batterio Gram-positivo) e l’Escherichia coli (batterio Gram-negativo). Risultati promettenti sono stati ottenuti contro i batteri Gram-positivi, mentre solo pochi campioni hanno mostrato una buona attività contro i batteri Gram-negativi.

Ce travail de thèse s’inscrit dans la partie caractérisation d’un projet collaboratif ayant pour objectif d’élaborer des textiles antimicrobiens pour différents domaines d’application, en particulier les domaines de la santé et de l’agroalimentaire. La démarche analytique a consisté à combiner différentes techniques d’analyse de surface (techniques microscopiques (SEM, AFM, TEM) et spectroscopiques (XPS, ToF-SIMS, SIMS, EELS)) avec des analyses microbiologiques pour aider à la compréhension des mécanismes de protection antimicrobienne des textiles traités. Les agents antimicrobiens, l’argent et le Poly HexaMéthylène Biguanide (PHMB), ont été déposés respectivement par plasma (PVD / PECVD) et par foulardage. Les contraintes liées aux domaines d’application des textiles étudiés (implants herniaires et vêtements professionnels) ont été prises en compte (respectivement, quantité minimale de l’agent antimicrobien et résistance au lavage industriel). Malgré certaines contaminations inhérentes à des procédés industriels, les analyses de surface se sont révélées être un ensemble d’outils essentiel au développement des procédés (qualité du dépôt, influence des conditions de dépôt, influence du lavage). Selon les domaines d’application, l’analyse à très haute sensibilité en extrême surface et l’étude de la distribution en profondeur de l’agent antimicrobien ont été des étapes clés pour la compréhension des propriétés antimicrobiennes observées pour les dépôts, démontrant la pertinence de l’approche multi-analytique choisie dans ce travail de thèse
This thesis work concerns the characterization effort within a cooperation project aiming at developing antimicrobial textiles for various application fields, particularly health applications and food-processing industry.

Silver and Poly Hexamethylene Biguanide (PHMB) antimicrobial agents were deposited by plasma (PVD / PECVD) and padding, respectively. Specific constraints related to the application fields (hernia implants and clothing) were considered (minimum concentration in antimicrobial agent and resistance to industrial washing, respectively). Despite some ubiquitous contamination related to industrial processes, surface analysis techniques proved to be an essential help to develop these processes (deposit quality, influence of deposition conditions, influence of washing). Depending on the application fields, high sensitivity surface analysis at the extreme surface and in-depth distribution of the antimicrobial agent were essential to understand the antimicrobial properties of the deposits, which confirms the relevance of the multi-analytical approach used in this thesis work

Streszczenie:

The goal of this thesis work was to investigate the antimicrobial effect of chitosan from zygomyzetes cell wall material in nonwoven textiles and compare it to commercially available chitosan. This was done using two methods, a somewhat modified version of AATCC Test Method 100-2004 (a standard method for quantitative testing of antimicrobial effect in textiles developed by the AATCC Committee) focusing on CFU, and TTC, a tetrazolium salt that changes from colourless to red in the presence of living microorganisms under the right conditions. The CFU method was also used to detect if it is possible to add chitosan earlier in the production stages, by scanning for any antimicrobial effect in test samples produced that way. Commercial chitosan added to the test samples in 2 % citric acid showed the strongest antimicrobial effect, even reaching the detection limit of approximately 99.5 % inhibition for both E. coli and K. pneumoniae without any incubation. Medium molecular weight commercial chitosan added in 2 % citric acid solution was also the only tested compound that could eliminate C. ablicans after 24 h incubation. Both commercial chitosan added as a powder and cell wall extract showed a mediocre inhibition without incubation, but were able to reach >99 % inhibition after 24 h incubation. Generally speaking, the chitosan investigated is comparable to the chitosan available commercially today, even if it required somewhat longer to reach the same levels of inhibition. The other method for addition of chitosan, however, did not work properly.

Streszczenie:

Textiles, today, are no more just traditional textiles. With the advancements in nano and fiber technology, they find various technical applications and are known as technical textiles. Antimicrobial functionalization is an integral requirement for some of these applications that include medical textiles, aerospace textiles and textiles used in filtration. Various organic and inorganic antimicrobial agents are being explored for antimicrobial functionalization of textiles with the objective to obtain effective, durable and broad spectrum antimicrobial properties. However, these antimicrobial agents may have their own advantages and disadvantages. Some of them may lack broad spectrum antimicrobial properties as well as complex method of their synthesis and application which may not always be environmental friendly. Silver is well known inorganic antimicrobial agent with effective antimicrobial action against broad spectrum of microbes. Silver is being intensively studied in nano particle form for the functionalization of textiles. However, mostly the synthesis and application of silver nano particles to textiles is carried through wet routes. These may have environmental considerations due to possible use of toxic reducing and stabilizing agents. In addition their solution or colloidal based application to textiles is intense in water and energy consumption along with production of waste water and necessitating its treatment. This may not help reduce environmental burden of textile industry which is regarded as one of the most polluting industrial sector of the world. Therefore, along with providing antimicrobial protection, the process of obtaining antimicrobial textiles itself should not create adverse environmental impact. In this context, ecofriendly processes for textile industry have always been in focus of research. The objective of this thesis was to achieve “antimicrobial functionalization of technical textiles for medical, aerospace and civil applications” via a simple and single step environment friendly technique known as radio frequency “co-sputtering”. Sputtering is a plasma based process and is mostly used in automotive, tools and electronics industry. It is not yet fully explored in textile industry. This study aimed at obtaining antimicrobial textiles via co-sputtering and exploring some of the its key strengths and weaknesses for textiles. In the adopted co-sputtering technique, an antimicrobial silver nano clusters/silica composite coating was deposited on four different textile substrates. The deposition parameters of both silica and silver were controlled independently such that silica constituted the matrix of the composite coating and silver was deposited in the form of nano clusters embedded in the silica matrix. The four textile substrates used in this study were: cotton fabric intended for medical applications, high performance Kevlar® and Vectran® fabrics for aerospace applications and activated carbon fabric (ACF) to be used in air filtration. The morphology and composition of the deposited coating was investigated in detail using FESEM, EDX and XPS which showed that silver nano clusters (25-50 nm) were uniformly distributed and firmly embedded in the silica matrix. Total silver concentration in the composite coating was evaluated through ICP_MS and was found to be dependent on deposition time and thus on coating thickness. Silver ion release test in water and in artificial sweat showed a progressive and gradual release of silver ions, beneficial for prolonged antimicrobial activity. The nature of the fabric substrate was also found to influence the release of silver ions. The coating showed effective antimicrobial properties against Gram positive (S. aureus, S. epidermidis), Gram negative (E. coli) bacteria and fungus (C. albicans) with varying intensity of the action depending upon the microbe as well as silver ion release profiles. Water contact angle and sorption tests revealed hydrophilic nature of the coating. Moisture management properties evaluated by Moisture Management Tester showed that coating imparted fast absorbing and quick drying characteristic to the fabric. The coating was highly conformal and did not altered air permeability of the substrates which is a highly desirable characteristic to preserve thermo physiological comfort of the fabric as well as maintain filtration capacity of ACF. However, the washing stability of the coating was found not to be completely satisfactory. The work was carried with in the frame wok of an Italian regional project with several other project partners. Some results from these partners, duly acknowledged, are also discussed in this thesis and summarized in conclusion.

Streszczenie:

Healthcare associated infections (HCAI) impose significant financial and environmental problems for modern healthcare settings, therefore it is important to develop novel strategies to combat HCAIs and the causative microorganisms. This study investigates the use of an encapsulated essential oil (EO) antimicrobial coating for textiles in the healthcare environment. The antimicrobial activity of several EOs were studied, individually and in blends, against five microorganisms associated with HCAI (Staphylococcus aureus, methicillin resistant Staphylococcus aureus, Candida albicans, Escherichia coli, and Pseudomonas aeruginosa). A 1:1 blend of cinnamon (CIN) and clove oils (CLO) containing 94.8 % (v/v) eugenol (by GC-MS) showed the highest antimicrobial efficacy and gave a minimum inhibitory concentration (MIC) of less than 0.25% (v/v). Mesoporous silica nanoparticles (MSN) were used to encapsulate volatile EOs. The MSNs displayed narrow size distribution, high surface area and pore size between 1.8-2.2 nm. MSNs, directly loaded with CIN:CLO blend (72 % by mass of MSN), achieved bactericidal values (25-50 mg/mL) against the test microorganisms. Dynamic killing profiles of the EO loaded MSNs against the test microorganisms were recorded. The highest kill rates were observed during the first 15 minutes of contact. Organically modified silica (ormosil) gels were synthesised to provide thin film coverage of synthetic fibres. Gamma-methacryloxypropyltrimethoxysilane (-MPS) was used to attach un-loaded MSNs to the ormosil coating. A layer-by-layer treatment method provided good coverage of synthetic fibres with MSNs, as evidenced by scanning electron microscopy (SEM). Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was used to monitor the layer-by-layer treatment sequence. Head space GC-MS sampling of EO loaded MSN treated textile coupons showed that EO was able to diffuse from the MSN mesopores after being bonded to the synthetic fibres. The EO loaded MSN textile coupons were microbiologically challenged using a method based on AATCC 100. The EO loaded MSN textile coupons displayed good antimicrobial activity over five washing cycles using a method based on (AATCC 61 and 135) thereby indicating a degree of controlled release.

Streszczenie:

Far infrared (FIR) functional textiles are a new category of functional textiles that have the potential to improve well-being and health. At the molecular level, FIR exerts strong rotational and vibrational effects with potential biological benefits. The majority of textiles with antimicrobial functionalization are based on synthetic products, and there is a need to link current end-user demands with both efficient products and low environmental impact, promoting natural antimicrobial treatments as viable solutions. Two structures of knitwear were obtained, with functional inorganic particles with antimicrobial, anti-UV and IR emission properties: variant 1: 100% BBC gauze ground yarn plated with functionalized polyamide yarn; variant 2: 85% wool/15% cashmere blend ground yarn plated with functionalized polyamide yarn. The antimicrobial efficiency of two types of functionalized materials was tested against six pathogenic microbial strains: Tricoderma viride (laboratory strain), Aspergillus flavus (laboratory strain), Candida albicans (ATCC 90028), Epidermophyton floccosum (CCM 8339), Trichophyton interdigitale (ATCC 9533) and Aspergillus niger (IMI 45551), highlighting various degrees of microbial reduction, depending on both the material and the tested strain, with lowest percentage microbial reduction of 9.67&, against Aspergillus niger strain, and highest of 86.65%, against Candida albicans.

The current study aimed to develop hydrogels as delivery systems based on a mixture of biodegradable and biocompatible polymers (i.e., gelatin and collagen) for encapsulating different active principles (i.e., chamomile and plantain tincture, aloe vera and propolis) to obtain dressings for treating first-degree burns injuries. The synthesized hydrogels were then immobilized on a textile material made from 100% cotton fibers. The functionalized textile materials were analyzed in terms of physical-mechanical characteristics, water absorbency and antibacterial activity. SEM analysis was used to investigate the morphology of the cotton fibers after the functionalized treatment. The antibacterial activity of the treated samples was qualitatively assessed through the Agar diffusion method by using cultures in a liquid medium of S. aureus and E. coli test strains. The obtained overall results indicated that incorporating of these active principles into the polymeric hydrogels can significantly enhance the potential efficiency of the fabrics as dressings with antimicrobial and healing accelerating properties and can be an appropriate option for treating first-degree burns injuries.

Streszczenie:

Since the beginning of the present century, tests have shown that some types of clay can present antibacterial activity. In addition, the clay considered for pharmaceutical and cosmetic products have been found to be non-toxic and non-irritating materials, therefore, the use of these types of clay for cosmetic and pharmaceutical purposes has increased in recent years. The above being said, different types of clay have been used over time due to their antibacterial properties, but the analytical methods for their characterization are just beginning to develop. This article is part of a study having as main objective the development of multifunctional antimicrobial textile materials to prevent fungal and bacterial proliferation, thus creating an antimicrobial shield for the human body, especially for blemish-prone skin. In this paperwork, a commercial blue clay was characterized through modern techniques. One of these techniques is X-ray Diffraction (XRD). Coupling SEM with an Energy Dispersive X-Ray detector (EDX), complete information of the morphology and elemental composition of the clay powder can be obtained. Additionally, a microbiological characterization was also performed in order to assess the anti fungal properties. Thus, the obtained results provided an overview of the main features of the selected blue clay. Further studies will be directed to the development of different types of clay-based dispersion and also for the characterization of different types of textile materials, in order to choose a "clay-textile" pair with improved antimicrobial activity.

Schiff bases, or azomethine compounds, are commonly employed in the fields of organic synthesis, metal complexes, materials, and engineering. Especially, they have gained importance in medicinal researches, considering their antimicrobial, anticancer, anti- inflammatory, and antioxidant properties. On the other side, azo dyes are the most significant group of synthetic dyes, utilized in textile fiber dyeing. Conjugation of Schiff bases with azo compounds leads to the class of azo-azomethine dyes, which have numerous applications related to their coloration and biological properties. Viscose is a textile material widely used in the medicine. Moreover, viscose fiber can be engineered in many ways which are significant in the development of medical materials. The antioxidant effect is an important feature of medical textiles, such as wound dressings. In this work, the microwave-assisted synthesis and characterization of novel azo-azomethine dye are reported. The azo-azomethine dye is obtained by the condensation between arylazo pyridone dye and 4-aminophenol. The structure of synthesized dye was determined by ATR-FTIR, NMR, and UV-Vis spectroscopy. Azo- azomethine dye was used for dyeing viscose, and the washing fastness of dyed material was evaluated according to the standard method. The viscose fabrics, before and after washing, were analyzed in terms of their color coordinates in the CIELab color space. The antioxidant properties of azo-azomethine dye and dyed viscose fabrics were examined by the ABTS method.

Streszczenie:

Responding to a sustainable production is an imperative that is gaining more and more relevance in the definition of specific programs and strategies at national and international level. This urgency leads towards zero waste and circular models and processes that minimize the extraction of resources from the biosphere and do not create waste; instead, when the waste of natural or anthropogenic transformations cannot be avoided, their valorization as resources must be carried out. The development of integrated supply chains, knowledge transfer between different disciplines and the dialogue between research and industry becomes fundamental for the achievement of these objectives. Existing studies in the literature regarding the agri-food production chain in Italy show that the sector, whose environmental impacts are by no means marginal, is fragmented in many small production companies; an interesting and critical aspect at the same time since the generation of waste is not accompanied by an appropriate dissemination of data at a quantitative-qualitative level and there is no clear regulatory framework available on alternative management and valorisation methods. Design, given its natural inclination to transversality, allows to trace scenarios in which to configure, through interdisciplinary approaches, the sustainability models that are intended to be covered in this contribution. Moreover, its methods and tools allow to develop a critical thinking starting from the very early designing phase. The paper addresses the valorisation of agro-industrial waste in a circular and systemic perspective through the presentation of a review of case studies from the textile supply chain, which is one of the most relevant for Italian industry.Due to its disastrous environmental impact, the global textile industry is today the subject of extensive research aimed at the development of innovative materials and processes in order to overcome the traditional linearity of the textile supply chain. The negative impacts of the textile industry are distributed along the entire value chain and are mainly attributable to greenhouse gas emissions -for which the textile industry represents the fifth manufacturing sector- consumption and pollution of water resources and the production of textile waste. In particular, the production of synthetic fibers, which is estimated to be almost two thirds of the global fiber production, is associated with a high use of non-renewable resources and emissions, which derives from the extraction of fossil fuels. In this sense, the valorisation of agro-industrial waste as secondary raw materials and new sustainable inputs for the textile supply chain, represents an opportunity not yet fully explored, in particular as regards the development of a new generation of fibers, yarns and eco-compatible fabrics alternative to the materials currently in use. Bio-based wastes and by-products from agri-food industry could as well present enormous potential for valorisation in the textile finish due to their intrinsic properties (antimicrobial, prebiotic, antioxidant activity, among others). At present, nevertheless, textiles from agro-residues do not completely meet the requirements to make them an attractive replacement for conventional fibre sources. Future research should therefore focus on identifying new agro-residue based blends that offer both performance and sustainability, adopting a systemic design approach based on interdisciplinary and interconnections as a strategy for innovation.

Streszczenie:

Water waste, contamination, and fossil fuel generated energy are acknowledged issues within the textile industry. Current dyeing processes pose serious threat to the environment and human health, often associated with toxic and carcinogenic substances that are released into the environment, through effluents not conveniently treated before being discharged into natural waters. Besides print and pattern, consumers demand for basic characteristics in textiles – these must resist to agents that cause colours to fade. On the other hand, industry must provide a great range of colours and access to huge quantities of coloured substance to dye. Simultaneously, it must be cost-effective. Natural dyes are perceived as less harmful for the environment due to its biodegradable nature. Studies reveal certain natural dyes possess UVR protection properties, as well as antimicrobial and anti-inflammatory assets. Nevertheless, depending on the nature of the dye, there are many advantages and disadvantages to consider.Through an extensive study on various fields such as Biotechnology, History, Ethnography, Biology, Archaeology, amongst many others we gathered information regarding natural coloured compounds, colour sources (plants, animals and microorganisms), ancient and modern techniques of extraction and application. This study shows the evolution of dyes throughout the centuries. It also reveals that the revival of natural dyes in addiction to new cutting edge technologies such as biotechnology might allow for an industrial feasibility.

Streszczenie:

Wound healing is a multiphase and multifactorial physiological process. The complexity of this phenomenon makes the healing process very difficult and painful due to several abnormalities. Apart from cellular and biochemical components, a number of external pathways also become active during repair and help the tissue to heal. Wound dressing is one of the main external effectors during the healing process of wounds. Wound is the disruption of the integrity of anatomical tissues caused by exposure to any factor [1-2]. The following characteristics are required for ideal modern wound dressings: bio-adhesiveness to the wound surface, ease of applications, easily sterilised inhibition of bacterial invasion, biodegradability, oxygen permeability, nontoxic, etc [3]. The balance between contraction and wound closure depends on the depth and location of the wound and the presence of complications, such as infection which could impair healing [4]. As a response to this problematic issue, as primary or secondary dressing, complex composites matrix for hemostasis and connective tissue regeneration were developed. The three-layered structure consists of outer layer I which plays the role of carrier, insulator and protector of the underlying layers, being elastic, resistant and submicro-porous (to block the physical access of microorganisms to the lesion), layer II – has the purpose of managing the liquid compositions in the lesion area, macroporous and compressible, with open pores and high tortuosity and layer III - impermeable substrate - non-adherent, biologically inert and microporous. The statistical indicators of the defining variables for each variant of textile structures (intended for layers I and III) are calculated, the histograms, the box plot graphs and the interactive spatial graphs, in the form of band type graphs are drawn. The obtaining of the substrate (II) based on hydrogel included an experimental plan with correlated factors, of the laticeal simplex type A {q, m}, with three factors (q=3) and four discretization intervals on the axes of the major simplex (m=4). The experimental matrix of the plan (dosed mass fractions) was designed, as well as the components of the mixtures. The plan was tested for optimality in D and A criteria. The measured experimental response was the apparent density of the hydrogel. The evaluation of the antimicrobial activity of the textile structures was performed using standardized strains: Staphylococcus aureus ATCC 6538, Escherichia coli ATCC 8739 and Candida albicans ATCC 10231. The biocompatibility assessment of textile supports for layers I and III was performed by MTT viability test and the LDH cell integrity test. The in vitro study for testing the biocompatibility of the functionalized multilayer matrix showed that they are biocompatible because the phenomenon of cell adhesion was present, regardless of the cell line used. In vivo testing according to ISO 10993-6 used the model of thermal burn injury on white rats (Wistar albino). The treated rats showed a rate of rapid healing and at 7 days of treatment the closure of the wound was observed between 40% - 60%, with areas of tissue regeneration. Inhibition of the invasion of exogenous microorganisms has been noted.

Review question / Objective: To compile evidence and determine the utility of various methods used to sanitize footwear and textiles, and the use of novel antimicrobial materials for eradication of pathogens known to cause superficial fungal infections of the foot. Rationale: Fungal infections of the feet such as onychomycosis are common, affecting approximately 6% of the global population. There are a number of available treatment methods for onychomycosis, with topical (e.g., efinaconazole, tavaborole, ciclopirox), oral (e.g., terbinafine, itraconazole, fluconazole), or a combination of both, being the most popular. Sanitization of shoes, socks/stockings, and other textiles (as well as the feet themselves through proper hygiene) is integral to the reduction, spread, and recurrence of superficial fungal infection. The goal of the present review is to examine the currently available methods of sanitization for footwear and textiles against superficial fungal infections, and assessing which are effective or not.
