Selected textile materials (polyester and polyamide woven fabrics, polypropylene non-woven fabric) were pre-treated by surface activation with low-temperature plasma at atmospheric pressure and subsequently finished using an antimicrobial (AMB) nanosol with a concentration of 60 ppm Ag+, 120 ppm Ag+ in the application solution. The goal was to increase the permanence of AMB nano-coating of textiles after washing and drying. To verify the effect of low-temperature plasma on increasing the permanence of the nanolayer, washing and drying was performed in accordance with the STN EN ISO 6330 standard. To determine antibacterial activity and effectiveness of the nano-coated textile materials, a quantitative test method was used in accordance with the technical standard AATCC TM 100. Evaluation of the antibacterial activity of the textile materials was performed before washing and after 20 washing cycles.","PeriodicalId":39508,"journal":{"name":"Vlakna a Textil","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134889014","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}

The metal oxide nanoparticle-contained fabric exhibits a self-cleaning effect under ultraviolet (UV) illumination. The nanostructure of the prepared samples was detected using Scanning Electron Microscopy (SEM) analysis. The chemical composition changes of the fabrics before and after the modification were detected using The Fourier transform infrared (FT-IR) and Energy Dispersive X-ray Spectroscopy (EDS). After modification with ZnO nanoparticles, the cotton fabric exerted adsorption and decomposition properties again various chemical compounds. Stains of methylene blue (MB), and methylene orange (MO) were introduced into cotton fabric, under UV light, the dyes were faded and ultimately discolored. The degradation of pigments in the solution happened faster and was expressed by the concentration of dyes decreasing over time through UV-vis measurement results. The self-cleaning ability for MB and MO stained cotton fabrics is evaluated quantitatively over time through the K/S value, which showed a good self-cleaning effect.","PeriodicalId":39508,"journal":{"name":"Vlakna a Textil","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134889023","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}

Main types of interaction of viruses with human cells are briefly described. The basic method of suppressing the spread of viruses from the surroundings of a healthy person and into the surroundings of an infected person is the use of protective equipment, especially face masks and respirators, where the active element is a fibrous structure. The protective functions of these structures depend on their composition (usually hydrophobic materials), construction (fabrics, knitted fabrics, nonwoven fabrics, nano-meshes), morphology (porosity, thickness, pore distribution), the form of virus propagation (usually in water droplets as a type of aerosol), interaction conditions with the surface of the protective layer (speed of impact, conditions of capture on the surface of the fibrous phase, speed of penetration) and the method of virus inactivation (usually contact or very short-range interaction). It is therefore a very complicated problem that is often solved using a combination of mathematical modeling and simulation. The purpose is to present some methods of solving problems related to the protective function of fiber structures, which allow the specification of the suitability of these structures for real use.","PeriodicalId":39508,"journal":{"name":"Vlakna a Textil","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134889777","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}

Seersucker woven fabrics are highly preferred in recent years due to their features such as providing wearing comfort and being user-friendly by not requiring ironing. However, in order to provide the three-dimensionality/wrinkle effect in woven seersucker fabrics in the currently used methods, it is necessary to use elastane in the weft/warp or to use double beams during production. At this point, it is not possible to produce completely natural fabric in the method using elastane, and in the other method, a special several warp and machine requirements are emerging. In this study, the literature on seersucker fabrics was reviewed and experimental seersucker weaving applications were carried out. Studies have been carried out in order to produce fabrics using completely natural raw materials (cotton), to improve production efficiency and to increase design possibilities. In this context, instead of the traditional methods used in seersucker fabric creation, seersucker fabric production was carried out with a single beam on the weaving machine by using different weaves in the dobby for fabric design. In this way, it has been provided that the seersucker weaving process can be performed with a single beam on any desired machine by using existing direct warps without the need for a special warp preparation.","PeriodicalId":39508,"journal":{"name":"Vlakna a Textil","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134889780","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}

They are resistant against high frequency repeat deformation but they are able to absorb water which is not optimal for use in different climatic conditions. Challenge is to create parachute fabrics made of PES multifilament yarns which are more versatile. Main aim of this work is to investigate influence of parachute fabric composition and construction characteristics on real end use properties. The relationships based on the prediction of bulk densities were used to calculate the volume porosity. The morphology of the parachute fabrics was evaluated using scanning electron microscopy. Mechanical and dynamic mechanical properties of parachute fabric Ortex made from multifilament PA 66 and PES yarns by Sky Paragliders company are compared.","PeriodicalId":39508,"journal":{"name":"Vlakna a Textil","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134889791","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}
