This paper study methods to obtain composite materials based on recycled rubber from End-of-Life tires and scrap textile. Rubber particles was obtained by industrial shredding procedures and separated by dimension, using sieves. Recycled cotton weave was obtained from scrap cotton textiles. The composite material was produced mixing the recycled rubber powder with a solution of acrylate rubber (AR), (NipolR AR 51) in acetone/ethyl acetate, then coating that composition on a 100% recycled cotton weave. After application, the composite was dried in a dryer with ventilation. The final composite material will be chemical characterized. Attempts will be made to determine whether the composite can be used as isolation material with temperature dissipation characteristics.

Electromagnetic shielding based on textile fabrics is important in applications for ensuring proper work of electronic equipment and for protection of human’s health. Fibre-based materials include a good capability for a precise design of the physical and electric properties of the EM shields. There are two main methods to impart electroconductive properties to textile fabrics: insertion of conductive yarns into the fabric structure and coating with conductive layers. In our approach, both methods were applied: cotton woven fabrics with conductive yarns of stainless steel and silver, were coated by magnetron sputtering with stainless steel layers. Electromagnetic shielding effectiveness (EMSE) was determined by Transversal-Electric- Magnetic (TEM) cell measurement system, according to standard ASTM ES-07. Moreover, EMSE was determined for the superposition of the manufactured textile shields. The stainless-steel plasma coating improves EMSE with 20 dB in case of the fabrics with stainless steel yarns and with 15-17 dB in case of the fabrics with silver yarns, in the frequency range of 0.1-1000 MHz. By superposition of the plasma coated shields, the gain in EMSE achieved was of 6 dB for the fabrics with stainless steel yarns and of 5-8 dB for the fabrics with silver yarns, on the same frequency range. EMSE has significant higher values in case of the superposed shields with silver yarns and stainless-steel coating for the frequency domain of 100-1000 MHz, due to the higher thickness and the significant contribution of the multiple reflection term.

Magnetic textile materials represent a new category of smart materials, whose properties are obtained either by adding magnetic materials during the technological processes of obtaining fibres and yarns, either by applying some magnetic materials on textile surfaces during the chemical finishing processes (electroless plating, electroplating, magnetron sputtering). Therefore, by adding magnetic nano powders in the spinning solution, fibres with magnetic properties are obtained, by adding metallic fibres, with magnetic properties, during the spinning process, magnetic yarns are obtained, and by the insertion of a certain percent of metallic/magnetic yarns during the weaving or knitting process, textile materials with magnetic properties are obtained. Thus, magnetic textile materials will possess the uniqueness of a textile structure due to specific features as flexibility, breathability or lightweight, but at the same time, also the magnetic properties necessary in multiple applications such as magnetic sensors, actuators and electromagnetic shielding used in technical applications for defence, automotive and aerospace.

Adolescence is a period of transition from childhood to adulthood, defined by major changes in physical, behavioural and social plan. The interest of teenagers for computer technology is in a perpetual growing and shopping online is one of their favourite activities. The garment industry is extremely competitive in terms of virtual simulation, consisting of 3D virtual bodies, virtual garments and virtual try-on systems. The paper presents the advanced method of designing 2D patterns, started from the 3D surfaces, obtained by real scanning of several teenager bodies. The development of a jacket model for girls, by using Optitex software with its high-performance modules 3D Flattening, 3D Simulations and PDS, based on the anthropometric standard for children, SR 13546: 2012, will be presented. These modules enable the designer to preview the shape of the product and its fitting to the body dimensions, which offer the possibility of developing to an infinite number of clothing collections just by changing the characteristics of the material, various seams, accessories or colours.

Textile materials are often subjected to different stresses, acting on them in two phases: during the knitting phase, when the yarns and the obtained structure are subjected to cyclic stress, but also during the use phase, when the knitted structures are subjected to various stresses. The dynamic behaviour of knitted fabrics in a vibrating environment is usually evaluated by standardized methods, such as the method using vibration exciters (e.g., ISO 10819:2013). However, in recent years, the authors' collective has carried out research to characterize the behaviour of knitted structures in a vibrating environment, using a well-known method for generating vibrations by impact excitation, which is specific to the mechanical field but also has a high potential for application in the textile field. This method refers to the determination of the free vibrations of an elastic system. Its measurement in the design phase of the system is considered a crucial step, since by knowing the frequency range of the system, the resonance phenomenon in the operational phase can be avoided. Similar results obtained by applying standardized methods for measuring vibration transmissibility and the currently adapted method from the field of mechanics to the field of textiles, represent a validation for this type of investigation process and also show the high potential of knitwear to be used in the vibration environment.

In this study, it was achieved that crosslinking of PVP/GEL nanofibers with two-steps. Crosslinking is a process highly important for water-soluble polymers in terms of application areas and mechanical properties. Firstly, crosslinking of PVP polymers experimental studies were carried out via heat treatment at different temperatures and times. Then, GEL polymers were crosslinked with GTA vapour at different times. Morphological analysis was carried out via SEM images and chemical characteristics were determined via FT-IR analysis. Moreover, after the crosslinking process, SD and WL values were calculated. All results showed that before crosslinking of SEM images, nanofibers were smooth, fine and without beads. The average fiber diameter is 196 nm and the fiber diameter distribution is quite uniform. After crosslinking of SEM images, it is expected that all nanowebs will turn from fibrous surfaces to membranous. Generally, SD and WL values decrease with crosslinking time increase. According to all of the SEM images, SD and WL values, optimum conditions were determined for PVP as 4 hours at 180oC and for GEL as 24 hours. Lastly, the presence of PVP and GEL polymers in the nanofiber structure was verified chemically with FT-IR analysis.

This paper presents the correlation and covariance analysis of the electrical resistance dependence of mass, thickness and air permeability of textile structures coated with magneto-conductive materials and used for protection against electromagnetic waves. For this scientific approach, 9 experimental models of compositesbased fabrics with electroconductive properties were made by applying different pastes based on organic polymeric matrices polyvinyl alcohol (PVA), copper (Cu), aluminium (Al), zinc (Zn), iron oxide (Fe3O4) and polypyrrole (PPY) solution using a classical deposition method such as scraping. The surface resistance was evaluated using a resistance meter device based on two parallel electrodes. From all samples analysed 5 samples based PPY, PVA-Ni, PVA–Ni-Al and PVA-Zn present a surface resistance between 103 and 105 Ω. Because the surface resistance has a lower value this means that the samples have a good conductivity to be used as layers for electromagnetic shielding systems.

One approach to develop innovative antimicrobial wound dressing materials is to use natural polymers loaded with antimicrobial agents. The valorisation of animal proteins as biomaterials with antimicrobial properties is a new concern for development of wound healing. Plant esssential oils (EO) also indicate a potential approach for new wound dressing materials able to replace the synthetic antymicrobial agents. In this paper, plant-polymeric film was prepared by casting film-forming emulsion based on lemongrass (Cymbopogon flexuosus) essential oil/Tween 80 dispersed into rabbit collagen glue hydrolysate– chitosan biomaterial. The effect of biomaterial film composition on Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 10536 standard bacteria, and Candida albicans ATCC 10231 pathogenic fungus was studied according to European Pharmacopoeia 10/2020 as compared with biomaterial film without essential oil. The in vitro antibacterial tests against three bacterial strains showed that the rabbit collagen glue hydrolysate–chitosan biomaterial inhibited all the three microorganisms. The rabbit collagen hydrolysate glue-chitosan film loaded with lemongrass essential oil exhibits antimicrobial activity towards tested microorganisms but lower as compared with control. The explanation could be due to the short time of investigation, or maybe some active compounds constituents of EO, which favour the cellular proliferation. Preparation of rabbit collagen glue hydrolysate-chitosan biomaterial loaded with lemongrass essential oil is an environmentally friendly solution, which may contribute to the development of wound healing materials as an alternative to topical antimicrobial agents.

In recent times, waste materials such as deadstock or used clothing have captured the fashion industry's attention. These materials have been the subject of studies to design sustainable production systems and new manufacturing techniques, intending to approach a circular economy model. In this context, the fashion industry has implemented strategic, design-led actions to prevent waste and promote recycling and recovery actions. Recycled textiles are fertile ground for fashion experimentation that, starting from the circular economy concept, can involve the entire textile supply chain: all the different actors working together proactively to encourage the establishment of industrial symbiosis systems between the districts. An excursion among the ideas and techniques applied to this field can show the possibilities of sustainable material-led approaches that can make a more positive future thrive.

In this research, biodegradation behaviour of nonwoven fabrics suitable for wet wipes having different fibre types such as regenerated cellulose (viscose and Tencel), polyethylene terephthalate (PET) and their blends were investigated. Each nonwoven fabric was buried in soil and test samples were controlled in regular periods. Visual appearance was reported and examined by photographs and microscopic views. According to the changes in visual appearance and weight loss, biodegradation was examined in a systematic way. It has been observed that regenerated cellulose nonwoven fabrics and the PET nonwoven fabrics show big difference under the same degradation conditions. PET fibre content delays biodegradation in the soil and degradation behaviour is similar the content of PET fibre in fabric structure. The higher PET, lower degradation, and the higher cellulosic fibre, the higher degradation was determined for nonwoven fabrics suitable for wet wipes.

The higher PET, lower degradation, and the higher cellulosic\u0000fibre, the higher degradation was determined for nonwoven fabrics suitable for wet wipes.","PeriodicalId":22214,"journal":{"name":"TEXTEH Proceedings","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78565241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
