Abstract:
Medical textile is an extremely important subcategory of technical textile because it is covering a wide range of products. The term medical textile itself covers all types of textile materials that are used in the healthcare system for various purposes. Medical textile is also known as health textile and is one of the fastest growing sectors in the technical textile market. The growth rate of technical textiles in this area is due to constant improvements and innovations in both areas: textile technologies and medical procedures. Textile structures used in this field include yarns, woven, knitted and non-woven textile materials as well as composite materials reinforced with textiles. The number of applications is large and diverse, from simple surgical sutures to complex composite structures for bone and tissue replacement, hygiene materials, protective products used in operating rooms and in the process of postoperative wound treatment. The purpose of this paper is to emphasize the importance of technical textiles for medical, surgical and healtcare applications, to indicate which textiles are currently used in this field.

Abstract:
AbstractThis work investigates changes in the physicochemical properties of dry multiuse medical textiles used in surgery and as packaging material in sterilization after 0, 1, 10, 20, 30, and 50 washing and sterilization cycles in real hospital conditions of the Clinical-Hospital Centre in Zagreb. Scanning electronic microscope (SEM) was used to perform morphological characterization. Physicochemical characterization and the resulting changes in the medical textiles were monitored using Fourier transform infrared (FT-IR) spectrometer. The change in the mass of the medical textiles as a results of temperature was determined by thermogravimetric (TG) analysis. Furthermore, structural characteristics based on the changes that resulted during the washing and sterilization processes are provided. The conclusion of the conducted research on the changes in the properties of multiuse medical textiles (Cotton/PES, Tencel®, and three-layer PES/PU/PES textile laminate) in real hospital conditions is that the medical textiles do manage to preserve properties after continuous use and it is safe to use them up to 50 washing and sterilization cycles.

Abstract:
The study focuses on the effects of Ag (silver) and Ti (titanium) ions on textiles by MEVVA (metal vapor vacuum arc) ion implantation. In order to comprehend this, the research was executed in three parts. In the first part, the antibacterial efficiencies of Ag and TiO2 were investigated in detail since the antibacterial capabilities of Ag and TiO2 are well known. A group of polyester- and cotton-based medical textiles were modified by Ag and TiO2 ions, with doses ranging from 5 × 1015 to 5 × 1016 ion/cm2. To determine the adhesion capabilities of the implanted ions on surfaces, after the first round of antibacterial tests, these medical textiles were washed 30 times, and then antibacterial tests were performed for the second time. The results were also compared with nanoparticle-treated medical textiles. In the second part, the corrosion and friction capabilities of Ag and Ti ion-implanted polyester textiles, with a dose of 5 × 1015 ion/cm2, were investigated. Finally, the UV protection capabilities of Ag and Ti ion-implanted polyester textiles, with a dose of 5 × 1015 ion/cm2, were investigated. The experiments showed that even after 30 washes, the TiO2 ion-implanted polyester textile had almost 85% antibacterial efficiency. In addition, Ti ion implantation reduced the friction coefficiency of a polyester textile by almost 50% when compared with an untreated textile. Finally, the Ag-ion-implanted polyester textile provided a UV protection factor of 30, which is classified as very good protection.

Abstract:
E-textiles, hybrid products that incorporate electronic functionality into textiles, often need to withstand washing procedures to ensure textile typical usability. Yet, the washability—which is essential for many e-textile applications like medical or sports due to hygiene requirements—is often still insufficient. The influence factors for washing damage in textile integrated electronics as well as common weak points are not extensively researched, which makes a targeted approach to improve washability in e-textiles difficult. As a step towards reliably washable e-textiles, this review bundles existing information and findings on the topic: a summary of common failure modes in e-textiles brought about by washing as well as influencing parameters that affect the washability of e-textiles. The findings of this paper can be utilized in the development of e-textile systems with an improved washability.

Abstract:
Fungal deterioration is one of the highest risk factors for damage of historical textile objects in Egypt. This paper represents both a study case about the fungal microflora deteriorating historical textiles in the Egyptian Museum and the Coptic museum in Cairo, and evaluation of the efficacy of several combinations of polymers with fungicides for the reinforcement of textiles and their prevention against fungal deterioration. Both cotton swab technique and biodeteriorated textile part technique were used for isolation of fungi from historical textile objects. The plate method with the manual key was used for identification of fungi. The results show that the most dominant fungi isolated from the tested textile samples belong to Alternaria, Aspergillus, Chaetomium, Penicillium and Trichoderma species. Microbiological testing was used for evaluating the usefulness of the suggested conservation materials (polymers combined with fungicides) in prevention of the fungal deterioration of ancient Egyptian textiles. Textile samples were treated with 4 selected polymers combined with two selected fungicides. Untreated and treated textile samples were deteriorated by 3 selected active fungal strains isolated from ancient Egyptian textiles. This study reports that most of the tested polymers combined with the tested fungicides prevented the fungal deterioration of textiles. Treatment of ancient textiles by suggested polymers combined with the suggested fungicides not only reinforces these textiles, but also prevents fungal deterioration and increases the durability of these textiles. The tested polymers without fungicides reduce the fungal deterioration of textiles but do not prevent it completely.

Abstract:
Biodegradable polymers are currently discussed for applications in different fields and are becoming of increasing interest in textile research. While a plethora of work has been done for PLA in medical textiles, other biodegradable polymers and their textile application fields are studied less often, presumably due to higher costs and fewer market opportunities. However, some are emerging from research to pilot scale, and are already utilized commercially in packaging and other sectors but not, unfortunately, in textiles. The commercialisation of such polymers is fuelled by improved biotechnological production processes, show¬ing that textile applications are increasingly conceivable for the future. Additionally, commonly accepted definitions for biodegradability are probably misleading, if they are used to estimate the environmental burden of waste management or recycling of such materials. In this review, the current state of research in the field of biodegradable polymers for the application in textile materials is presented to identify emerging developments for new textile applications. It was clearly seen that PLA is most dominant in that field, while others facilitate new options in the future. The production costs of raw materials and the current patent situation are also evaluated. A special focus is placed on fibre raw materials, coatings, and additives for clothing and technical textiles. Fibre-reinforced composites are excluded, since polymers applied for the matrix component require very different properties compared to the textile materials. This represents a topic to be discussed separately. As a result, these new biodegradable polymers might serve as interesting coating materials for textiles that seem to sneak on to the textile market, as the patent search for such coating formulations suggests. Moreover, new biodegradable fibrous materials for clothing applications can be suggested, but some material properties must be addressed to render them processable on common textile machines.

Abstract:
Technical textiles are one of the fastest emergent sectors of textile industries worldwide. Medical textiles and healthcare textiles are the most important development areas within technical textiles. A rapid advancement in the health care and hygiene sector together with an increase in health consciousness has made medical textiles an important field. In order to protect people against harmful pathogens, an antimicrobial textile has been developed and as a result, finishes began to evolve in recent years. A critical problem regarding healthcare and hygiene products chemical based synthetic antimicrobial finishes or coatings for infection control. To provide the potential solution and to avoid such critical problem, seaweeds may be used. Seaweeds are plant-like organisms that commonly live attached to rocks in the coastal areas. Seaweeds of brown, green and red colour contain major pigments such as chlorophyll, carotenoids, phycobiliproteins, beta carotene and lutein; these are used for the extraction of natural dyes in textiles. Marine macroalgae (seaweeds) is rich in bioactive compounds that could potentially be exploited as functional ingredients with potential medicinal, health care or pharmaceutical activities for both human and animal health applications. The present review discusses the research potential of different bioactive compounds and its salient features that are mainly responsible for the antioxidant and antimicrobial properties present in seaweeds and their applications in the area of medical textiles.

Abstract:
As science and technology has developed, the manner by which drugs can be delivered has grown. This research explores an alternative method for the delivery of therapeutic compounds to the body. The basis of the study involves the application of traditional medicines on textiles. Boswellia Serrata Extract (B.S.E.) is a common traditional medicine used for curing body pains. The most common form of B.S.E. based products are creams that are applied directly to the skin. Experiments show that these creams were not suitable as a basis for applying to textile materials because the creams contain highly volatile compounds, which on drying the treated textile, post application, cause almost total loss of the B.S.E. The approach used was the application on textiles of a 'commercial' topical medicine applied as a cream for, where B.S.E. is a major constituent. Cotton woven fabric was padded with this cream and tested for washing and rubbing fastness. The presence of highly volatile substances in the topical cream resulted in a negligible amount of the medicine on the dried treated fabric. Another approach was used for the application of B.S.E. onto the textile substrate. A commercially available B.S.E. powder was applied to woven fabric using a pad mangle. Tests were carried out to validate the

Abstract:
The Sonochemistry Centre at Coventry University is one of a group of organisations working on a project to develop a new technology for producing antimicrobial textiles. This technology involves the use of an ultrasonic process (sonochemical) to generate and impregnate fabrics with antibacterial metal oxide nanoparticles. The expectation is that these textiles can be produced at an affordable price for routine use in hospitals as uniforms, curtains, hospital bed sheets and linen. The aim of this PhD project was to assess the antibacterial activity of fabrics impregnated with ZnO and CuO NPs against a variety of Gram positive and Gram negative bacteria. The testing was principally carried out according to the absorption method from ISO 20743:2007. Research was also extended to compare different methods of assessing antibacterial activity of textile fabrics. These included disc diffusion tests and shake flask tests in saline or nutrient broth. Overall the results from absorption tests demonstrated that both the ZnO and CuO impregnated fabrics showed very good levels of antibacterial activity (A>2) against the test bacteria (Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa). During the optimisation of lab scale process to the pilot scale, two different types of CuO fabrics were produced to test and compare the antibacterial activity. One type of fabrics were impregnated with pre-made CuO nanoparticles by a ‘throwing the stones’ technology termed TTS and the other with sonochemically formed nanoparticles (in-situ), same as the lab process. The results indicated that the fabrics impregnated with sonochemically formed NPs displayed better antibacterial activity than the pre-made NPs. Leaching of the antibacterial agents in to saline was investigated using a shake flask method. CuO and ZnO coated fabrics prepared at laboratory scale were tested against Staphylococcus aureus, Acinetobacter baumannii and Escherichia coli. It was found that leachates prepared by shaking the fabrics in saline for 3 hours showed no antibacterial activity for CuO fabrics. However, leachates from ZnO fabrics showed an excellent activity after 24 ± 3 hours against all three bacterial species. Flow cytometry (FC) was investigated as an alternative to standard agar plate count (PC) methods for the determination of viable cell numbers. There was a general agreement between the results from agar plate counts and flow cytometry except that post incubation counts were greater with FC. The higher numbers of viable cells detected with FC may have been due to the presence of viable but not culturable cells (VBNC). Viable cells were observed by fluorescence microscopy in post incubation samples in which no viable cells were detected on nutrient agar plates. Cytotoxicity studies were conducted on ZnO and CuO fabrics from the pilot scale (both in-situ and TTS) against human dermal fibroblast cells (HDF) and human hepatocellular carcinoma cells (HepG2) using a MTT assay to determine cell viability. The results showed that ZnO and CuO are not toxic to HDF cells. However, cytotoxicity was seen in HepG2 cells with cell viability decreasing by > 14% for all the fabrics after 24 hours.

Abstract:
Technical textiles are one of the fastest growing sectors of the global textile industry, especially in the medical application which is considered as one of the most important applications of technical textiles. Plaster (gypsum) and plastics casts are widely used nowadays in hospitals, pharmacies and health care centers. But they are heavy, not washable, do not offer a suitable fixation for bone fractures (e.g. hand wrist) and always in individually sizes. After decrease of swelling, the cast is in a hard form and the stabilization effect of the cast is insufficient due to the occurring of distance between the skin and the cast. In this work, a new pneumatic cast is developed, that depends on a coated fabric as an outer layer, skin friendly fabrics as internal layers, air chamber and metal braces. For more comfort, the cast is anatomically formed and includes four internal layers of cotton/viscose fabric and polyester spacer fabric. The new developed cast controls the pressure on the injured part by using a pneumatic system. In a comparison with plaster and plastic casts that are heavy, not washable, provide an insufficient fixation after swelling decrease and always in individually sizes; the new developed pneumatic cast is light weight, easy to use, washable, mass-produced and offer the required fixation to the injured part during swelling conditions.

Abstract:
Polyurethane (PU) foam has unique characteristics making it suitable for many applications such as: aeronautics, automotive, building construction, marine, and many house-hold applications. PU’s biodegradability, biocompatibility, lightweight, and durability make it suitable for several medical applications. The porous structure of PU foams enables them to be used for lightweight components and for medical applications where the permeability allows nutrients to reach cell growth areas. The foam components are currently mainly manufactured by material removal i.e. subtractive machining or a casting/moulding processes. Additive Manufacturing (AM) processes (3D printing), build components in 2D layers and have been utilised to manufacture a range of products for many applications including: jewelry, footwear, industrial design, architecture, engineering and construction, etc. The additive processes have the ability to generate internal hollow structures or scaffolds. The nature of parts produced by AM technologies makes it fit for lightweight products such as aerospace parts, medical scaffolds, etc., in metals and polymers, however the technology has not been used to produce objects using PU as its material, due to the foaming nature of the material when its two base materials (polyol and Diisocyanate) encounter with each other. This research has undertaken a critical review of PU foaming processes, medical applications, and characteristics of AM technology processes. The effect of resins mixing ratios, temperature, and foaming direction on the physical and mechanical properties of PU foam have been investigated and used as a base to establish a platform for further development. The research has evaluated the suitability of Additive manufactured PU foam structures for further application such as medical scaffolds by comparing the foams produced using traditional method and have developed an AM production method (In-flight mixing system) for the material (PU). Based on the evaluations, a new technique has been pro-posed and tested which is able to generate PU 3D structures. Foam produced by the designed system has average pore size of 689μm which will allow the following: the flow of fluid such as blood, diffusion of waste products out of the scaffold, and cell infiltration and can therefore be suggested for the production of medi-cal scaffolds.

Abstract:
I december 2019 rapporterades de första fallen av ett virus benämnt som covid-19 i Wuhan, Kina. Viruset sprider sig snabbt och i takt med den okontrollerade spridningen blir också trycket på sjukvården allt högre. Samtidigt som vården gör allt i sin makt för att räcka till så rapporteras det om global brist på skyddsutrustning. Tillverkningen av ett kirurgiskt munskydd, från fiber till färdig produkt, består av ett omfattande system och kräver material av specifika fibrer som framställs i avancerade processer. Att skapa ett munskydd som besitter möjligheten för återanvändning hade varit ett alternativ i syfte att minska risk för att munskydd tar slut samtidigt som engångsförbrukning minimeras. Syftet med denna studie är att studera och analysera materialval, framställning, konstruktion och krav för kirurgiska munskydd. Studien syftar också till att undersöka alternativa möjligheter till att skapa ett återanvändbart munskydd. Val av metod för insamling av material har haft sin utgångspunkt i litteraturstudier av främst vetenskaplig karaktär. Då ämnet är högaktuellt har nyhetsartiklar från betrodda dagstidningar varit av värde. Intervjuer av kvalitativ läggning genomfördes i syfte att skapa en överskådlig inblick i vårdarbetet. Ett kirurgiskt munskydd fungerar som en skyddande barriär mot överföring av smittämnen mellan personal och patient och är generellt uppbyggt i tre olika lager. Det inre lagret, mittenlagret, är tillverkat genom en process kallad nonwoven meltblown medan de två yttre lagren, det övre och det undre, tillverkas genom en process kallad nonwoven spunbond. Dessa tre lager kalendreras sedan samman och bildar själva filtermediet som därefter veckas och sys i en konverteringslinje. Munskydd är en engångsvara och slängs direkt efter användning. Nawar Kadi, som är professor på Textilhögskolan i Borås, arbetar för tillfället med ett projekt som syftar till att utveckla ett delvis tvättbart munskydd som fungerar att återanvända. I dagsläget finns många aspekter att beakta och frågor att besvara innan projektet går att förverkliga i praktiken men med rätt förutsättningar, ekonomisk stöttning och framförallt beprövade metoder med bakomliggande forskning är möjligheten till att skapa ett återanvändbart munskydd inte långt borta.
In December 2019, the first cases of a virus called covid-19 were reported in Wuhan, China. The virus is spreading rapidly and in connection with the uncontrolled spread, the pressure on healthcare is also increasing. At the same time as healthcare is doing everything in its power to suffice, a global lack of protective equipment is reported. The manufacture of a surgical face mask, from fiber to finished product, consists of a comprehensive system and requires materials of specific fibers produced in advanced processes. Creating a face mask that possesses the possibility of reuse would have been an alternative with the aim of reducing the risk of face mask ending while minimizing disposable consumption. The purpose of this study is to analyze material selection, manufacture, construction and requirements for surgical face masks. The study also aims to explore alternative ways of creating a reusable face mask. The choice of method for collecting material has been based on literature studies of a primarily scientific nature. As the topic is highly current, news articles from trusted newspapers have been of value. Qualitative interviews were conducted with the aim of providing a clear insight into the healthcare work. A surgical face mask serves as a protective barrier against the transmission of infectious agents between staff and patients and is generally constructed in three different layers. The inner layer is made by a process called nonwoven meltblown, while the two outer layers, the upper and the lower, are made by a process called nonwoven spunbond. These three layers are then calendered together to form the filter media, which is then pleated and seamed in a converting line. The surgical face mask is a disposable item and is discarded immediately after use. Nawar Kadi, who is a professor at Textilhögskolan in Borås, is currently working on a project aimed at developing a partially washable face mask that thus functions to reuse. At present, there are many aspects to consider and questions to answer before the project can be realized in practice but with the right conditions, financial support and proven methods with underlying research, the possibility of creating a reusable face mask is not far away.

Abstract:
L'utilisation des microcapsules fabriquées à partir de matériaux respectueux de l'environnement pour des applications textiles médicales a été étudiée et développée fortement au cours des dernières années. Le but de cette thèse est d'élaborer les textiles anti-inflammatoires à base de microcapsules respectueuses de l'environnement, utilisant trois types de matériaux textiles (coton, peco 65/35 et polyester) et cinq niveaux de longueur de boucle (2.81, 2.83, 2.87, 2,96 et 3,05 mm) sur étoffes tricotées à verrouillage de coton (nombre de fils Ne40). Les influences de la concentration en saponine, de la vitesse d'agitation au cours de l'étape d'émulsification et du volume d'éthyle acétate ajouté à la phase aqueuse sur les caractéristiques des microcapsules ont été étudiées. L'étude a également étudié les effets du rapport massique du coton et de la longueur de boucle des étoffes tricotées sur la distribution des microcapsules, la capacité de chargement des microcapsules et la capacité de libération de l'ibuprofène des étoffes tricotées traités par microcapsules. Les microcapsules d'Eudragit RSPO contenant de l'ibuprofène ont été élaborées par la technique d'évaporation de solvant, en utilisant le tensioactif bio-sourcé quillaja saponine et le solvant non halogéné d'éthyle acétate. Les microcapsules obtenues présentaient les formes sphériques avec un diamètre d (0,5) de 21,5 μm, approprié pour les applications textiles. Il a été trouvé que, pour empêcher la déformation des microcapsules pendant la traitement du textile, la séchage doit être effectuée sous vide à 45 ° C. Lorsque le rapport de teneur en fibres de coton dans le tissu augmentait, la distribution des microcapsules était moins régulière, ce qui entraînait un taux de libération plus faible de l'ibuprofène à partir des étoffes tricotées traités aux microcapsules. En outre, lorsque la longueur de la boucle augmente, la capacité de chargement des microcapsules des étoffes tricotées traités augmente, la distribution des microcapsules sur le tissu devient moins régulière et la vitesse de libération de l'ibuprofène des tissus traités aux microcapsules diminue. De plus, l'augmentation de l'extension du étoffes tricotées a favorisé la libération d'ibuprofène à partir des étoffes tricotées traités par les microcapsules à travers la peau de porc
The use of the microcapsules made from eco-friendly materials for medical textile applications has been researched and developed strongly in recent years. The aim of this thesis is to elaborate the anti-inflammatory textiles basing on eco-friendly microcapsules,using three kinds of textile materials (cotton, peco 65/35 and polyester)and five levels of the loop length (2.81, 2.83, 2.87, 2.96 and 3.05 mm) on the cotton interlock knitted fabrics (yarn count Ne40). The influences of the saponin concentration, the stirring rate during the emulsification step and the volume of ethyl acetate added to the aqueous phase on the characteristics of the microcapsules were studied. The influence of condition in drying on microcapsule’s morphology was also investigated.The thesis also researched the effects of cotton mass ratio and loop length of fabric on the microcapsule distribution, the microcapsule loading capability and the release capability of ibuprofen from the microcapsule treated fabrics. The Eudragit RSPO microcapsules containing ibuprofen were successfully elaborated by solvent evaporation technique, using the bio-sourced surfactant quillajasaponin and the non-halogenated solvent ethyl acetate. The obtained microcapsules exhibited the spherical shapes with d(0.5) diameter of 21.5 m, suitable for the textile applications. It was found that in order to keep the microcapsules from deformation during the textile finishing, the drying stage should be carried out in vacuum at 45oC. When the content ratio of cotton fibers in the fabric increased,the microcapsule distribution was less even, resulting in the lower release rate of ibuprofen from the microcapsule-treated fabrics. Besides, when the loop length increased, the microcapsule loading capability of the treated fabrics increased, the microcapsule distribution on the fabric became less even and the release rate of ibuprofen from the microcapsule-treated fabrics decreased. Furthermore, increasing the fabric extension favored the release of ibuprofen from the microcapsule-treated fabrics through the pigskin

Abstract:
In recent years, due to the combination of technological advances in the fields ofmeasurement instrumentation, communications, home-health care and textile-technology thedevelopment of medical devices has shifted towards applications of personal healthcare.There are well known the available solutions for heart rate monitoring successfully providedby Polar and Numetrex. Furthermore new monitoring applications are also investigated. Amongthese non-invasive monitoring applications, it is possible to find several ones enable bymeasurements of Electrical Bioimpedance.Analog Devices has developed the AD5933 Impedance Network Analyzer which facilitatesto a large extent the design and implementation of Electrical Bioimpedance Spectrometers in amuch reduced space. Such small size allows the development of a fully wearable bioimpedancemeasurement.With the development of a Electrical Bioimpedance-enable wearable medical device in focusfor personal healthcare monitoring, in this project, the issue of power management has beentargeted and a battery-driven Electrical Bioimpedance Spectrometer based in the AD5933 hasbeen implemented. The resulting system has the possibility to operate with a Li-Po battery with apower autonomy over 17 hours.

Abstract:
To prevent the renewed rupture of ligaments and tendons prior to the completed healing process, which frequently occurs in treated ruptured tendons, a temporary support structure is envisaged. The limitations of current grafts have motivated the investigation of tissue-engineered ligament replacements based on the braiding technology. This technology offers a wide range of flexibility and adjustable geometrical and structural parameters. The presented work demonstrates the possible range for tailoring the mechanical properties of polyester braids and a variation of the braiding process parameters. A finite element simulation model of the braiding process was developed, which allows the optimization of production parameters without the performance of further experimental trials. In a second modelling and simulation step, mechanical properties of the braided structures were virtually determined and compared with actual tests. The digital element approach was used for the yarns in the numerical model. The results show very good agreement for the process model in terms of braiding angles and good agreement for the structural model in terms of force-strain behaviour. With a few adaptions, the models can, thus, be applied to actual ligament replacements made of resorbable polymers.

Abstract:
Current generation of textiles, including technical textiles are passive. However, the next generation of textiles will have the ability to monitor its environment and interact accordingly in order to accomplish a pre-programmed functionality. One of the solutions for incorporating the above components into a textile structure is to create electrically active zones within the structure, whose electrical characteristics could vary due to an environmental change or whose structural properties could be changed by the application of an electrical signal, for example change of dimensions due to the flow of an electrical current in the electrically active area. Generally textiles are made out of materials of very high electrical resistance and therefore these structures can be considered as materials with good electrical insulating properties. In this paper we are presenting application of electrically active textiles for strain gauge application. Electromechanical tests shows the chractersitics of electronic textile for strain gauge application.

Abstract:
Abstract Anisotropic textiles are commonly used in wearable applications to achieve varied bi-axial stress-strain behavior around the body. Auxetic textiles, specifically those that exhibit a negative Poisson’s ratio (v), likewise exhibit intriguing behavior such as volume increase in response to impact or variable air permeability. Active textiles are traditional textile structures that integrate smart materials, such as shape memory alloys, shape memory polymers, or carbon nanotubes, to enable spatial actuation behavior, such as contraction for on-body compression or corrugation for haptic feedback. This research is a first experimental investigation into active auxetic and shearing textile structures. These textile structures leverage the bending- and torsional-deformations of the fibers/filaments within traditional textile structures as well as the shape memory effect of shape memory alloys to achieve novel, spatial performance. Five textile structures were fabricated from shape memory alloy wire deformed into needle lace and weft knit textile structures. All active structures exhibited anisotropic behavior and four of the five structures exhibited auxetic behavior upon free recovery, contracting in both x- and y-axes upon actuation (v = −0.3 to −1.5). One structure exhibited novel shearing behavior, with a mean free angle recovery of 7°. Temperature-controlled biaxial tensile testing was conducted to experimentally investigate actuation behavior and anisotropy of the designed structures. The presented design and performance of these active auxetic, anisotropic, and shearing textiles inspire new capabilities for applications, such as smart wearables, soft robotics, reconfigurable aerospace structures, and medical devices.

Abstract:
Abstract Poor posture leading to neck and back pain can be caused by long hours sitting in front of computer screens in ergonomically inadequate office furniture or in makeshift home offices. For most individuals, recognizing and correcting for poor posture is an uncommon practice. Poor seated posture is characterized by protracted scapulae, increased kyphosis, and a flexed lumbar spine. Toward a wearable system that performs continuous monitoring, we developed a textile sensor embedded garment. Using textile sensors sewn into a shirt, we test the capability of our design to read curvatures related to seated posture. First, textile sensors were evaluated for fabrication and data collection ease. Next, sensors embedded in shirt designs were evaluated for their ability to produce data that can be recognized as good or poor posture across a user’s back. Designs leveraging e-textiles and snap circuitry enable textile sensor posture readings in a wearable device that is soft and durable. Results from this proof-of-concept prototype show that such customizable garments may enable the study of specific muscle groups related to various postures in the future. Sensor technology embedded in everyday wear garments holds promise for integrating continuous postural monitoring to commercially available clothing.

Abstract:
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.
