In this study, it was aimed to production and characterization of paracetamol (PCT) loaded microcapsules and microcapsule added electro spun PVA nanofibers. Eudragit RS 100 and PVA were used as the shell in the microcapsule structure, and PCT was used as the core material. First of all, the PCT loaded Eudragit RS 100/PVA microcapsules were produced by solvent evaporation method under the optimum process parameters. Then, properties such as conductivity, viscosity and surface tension of the microcapsule loaded PVA solution were measured and the effects of microcapsule concentration on the solution properties were determined. According to the solution results, while the viscosity increased with the microcapsule concentration, conductivity and surface tension did not change significantly except for the PVA-10 sample. After the electrospinning process, fibre morphology was determined by SEM and incorporation of microcapsules into the nanofibers was clearly demonstrated. It was calculated from the SEM images that average microcapsule size is 9.81μm, average fibre diameter is 550 nm and fibre diameter uniformity coefficient is 1.025. Finally, the incorporation of PCT loaded microcapsules into the nanofibers was chemically confirmed by FT-IR analysis. It is thought that the results of this study will be useful for controlled drug release, especially in medical textiles.

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%.

This work presents several aspects concerning the e-learning courses about composite materials developed for capacity building in the field of advanced materials for new or upgraded research centers in Morocco and Jordan. The proposed course for capacity building in the field of advanced materials development is represented by 3D advanced composites obtained through textile technologies and additive manufacturing processes. This course presented using e-learning technologies received increased interest from students attending the learning sessions in the framework of the Fostex Erasmus+ project because can be applied to obtain composites for a large area of industries such as automotive, construction, medicine, electronics/electrotechnical and aerospace. The textile composites are materials made from 2/more constituent materials with different chemical, physical and electrical properties. When combined, these materials generate a material (composite) with different characteristics than the initial individual components. The design and development of the composite can lead to new materials with superior characteristics: more robust, lighter, flexible, and less expensive in comparison with traditional materials such as metal, ceramics.

Fabrics produced from microfilaments are superior to conventional fiber fabrics, due to their properties such as light weight, durability, waterproofness, windproofness, breathability and drapeability. Tightly woven fabrics produced from microfilament yarns have a very compact structure due to small pore dimensions between the fibers inside the yarns and between yarns themselves. It is almost very difficult to distinguish the structures of densely woven fabrics with the visual evaluation. Therefore, it is very important to automatically determine the differences in the texture properties of such fabrics. Thanks to the developments in image acquision technology and image processing methods, the texture classification of fabrics can be estimated more quickly and reliably than visual inspection. In this study, the classification of high-density microfilament woven fabrics according to different texture types and thread density was achieved by using the ResNet-50 algorithm. The obtained results were evaluated in a confusion matrix form. The classification accuracy of the CNN algorithm was measured as 0.95 on average.

The awareness of the fact that the leading cause of the bad environmental conditions in our world is the human factor, has been increasing in recent years. This awareness enables people, companies, and organizations to decrease water consumption, to decrease carbon emission, to decrease using harmful chemicals, consequently people who are aware of global warming and depletion of resources are taking actions to save our planet for a sustainable life. Textile is one of the big sectors affecting the environmental pollution in a very bad way. For that reason, the present water footprint research was conducted on textiles and a denim company was especially chosen to examine the water footprint because of denim sector’s being one of the biggest polluters and wasting water in a huge amount in the textile industry. Firstly, the limits of the research were obtained as finishing operations under the scope of water footprint. The production steps and wastewater occurring points were obtained carefully for different denim finishing processes. After that stage, personal water consumption during denim apparel production was examined in detail. To create a good inventory analysis, many meetings were performed, and a survey was prepared to collect the data about wastewater of the company. By the help of this water footprint evaluation, the processes that create the most wastewater and the distribution of water footprint according to processes and other sources that cause water consumption were determined for one pair of denim trouser accepted as a functional unit in the context of the research.

Traditional uses of clay as medicine started in prehistoric times (Aboriginal times). Natural clays have been used in ancient and modern medicine, but the mechanism that makes certain clays lethal to bacterial pathogens has not been yet identified. The aim of this paper is to identify the proper clays that could be used in textile industry for improving textiles` functionality, based on the information extracted from literature. It is important, to differentiate between the properties that make a clay ‘healing’, versus what makes it ‘antibacterial’. So far, literature is abundant in reports regarding ‘healing’ clays, but, when tested against pathogens in vitro and compared to controls, they do not appear to have bactericidal properties. The studies carried out up to this point established that the physical adsorption of water and organic matter is the main feature which leads to healing properties of clays; however, the chemical interaction between clay and bacteria has received less attention. Clay properties, with potential application in medicine, have recently been started to be investigated and the results indicate that certain natural clays can have noticeable and extremely specific effects on microbial colonies. Further studies will be directed towards the characterization of the selected ‘claytextile’ pairs.

Functional properties such as; water resistance, flame retardancy, antibacterial efficiency etc. are required from textile products. One of the most commonly demanded products among functional textile products is the flame-retardant textiles. In this study, it is aimed to produce polypropylene filament yarn with permanent flame retardancy functionality by adding boron compound, which is Anhydrous disodium tetraborate powder (particle size < 38 micron), to the fiber structure during melt spinning process. In this study two different yarn samples are produced with anhydrous disodium tetraborate content by mass ratios of 2% and 5%. A control polypropylene filament yarn sample is also produced with no additive. By this way, three samples are produced by a conventional BCF polypropylene melt spinning machine with the same production parameters. Then, three knitted fabric samples were produced flat knitting machine. Limiting Oxygen Index (LOI) and vertical flammability tests were applied to the samples. According to results an important level of increase for LOI value is obtained with the sample which has 2% boron compound additive. Nevertheless, there is not a consistent effect of increasing boron content in yarn structure for LOI value. The reason of this situation may be resulted due to the uneven distribution of the boron compound in the yarn structure because of the particle size.

Nano and micro plastics (NP/MPs) represent one of the most challenging classes of micropollutants, with occurrence across all ecosystems and size distributions ranging from the nanometre to the millimetre scale. Natural environments are receiving MPs in the form of anthropogenic direct release as well as disintegrated and loose products of larger plastics via biological activities, mechanical abrasion, and UV radiation. During the processing steps, the textile yarns are subjected to friction either by different driving organs or between themselves at the binding points. The magnitude of the friction forces is influenced by the nature of the yarns, the structure of the yarn, the type, and the raw material from which the driving organs of the machines are made. The paper presents the shape and dimensions of the particle that is released in the air during the abrasion resistance test of three types of polyester yarns: spun yarn, multifilament yarn, and monofilament yarn. The structure composition of the particles consists of more microfibrils (34%.) in the case of spun yarn and the finest microparticles were obtain from monofilament yarn (0,004μm).

During the processing steps, the textile yarns are subjected to friction either by different driving\u0000organs or between themselves at the binding points. The magnitude of the friction forces is influenced by the\u0000nature of the yarns, the structure of the yarn, the type, and the raw material from which the driving organs of\u0000the machines are made. The paper presents the shape and dimensions of the particle that is released in the air\u0000during the abrasion resistance test of three types of polyester yarns: spun yarn, multifilament yarn, and\u0000monofilament yarn. The structure composition of the particles consists of more microfibrils (34%.) in the case\u0000of spun yarn and the finest microparticles were obtain from monofilament yarn (0,004μm).","PeriodicalId":22214,"journal":{"name":"TEXTEH Proceedings","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88178799","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}
