This contribution is aimed at comparing two quantitative methods for determining the antibacterial effectiveness of non-woven textiles and assessment of permanence of the antimicrobial finish of the nonwoven textile materials prepared from polypropylene fibers. Experience and results obtained by the quantitative test methods specified in AATCC TM 100 and STN EN ISO 20743 intended to evaluate the effectiveness of the antibacterial finish are published in the contribution. Emphasis is placed on comparability of the selected test methods, on the test microorganism used in the study as well as on evaluation of the results of antibacterial effectiveness. The non-woven fabrics, that were the subject of the evaluation, were pre-treated by surface activation with low-temperature plasma at atmospheric pressure and subsequently finished using antimicrobial (AMB) nanosol solution with a concentration of 15 ppm Ag+, 30 ppm Ag+, 60 ppm Ag+ and 120 ppm Ag+. Antibacterial effectiveness before washing and after 5 washing cycles is demonstrated on the specific examples obtained from practice.

The article is aimed at evaluating the air permeability of various types of non-woven fabrics prepared by Spunbond, Spunbond-Meltblown-Spunbond technology and non-woven fabrics reinforced mechanically by needling and thermal calendering. These are commercially available non-woven fabrics with various mass per unit area and thickness made of 100 % polypropylene, without special surface finish. By combining individual types of non-woven fabrics, three-layer and four-layer textile materials were prepared, meeting the minimum requirement of technical standardization information TNI CWA 17553 for air permeability, intended for application in the community face masks. As part of the experimental works, the effect of increased humidity on the air permeability of three-layer non-woven fabrics was verified as well.

This work is devoted to the study of antimicrobial properties of cellulose-containing textile materials treated with new safe biocidal products of thiosulfonate structure. A resource-saving method of providing antimicrobial properties to cellulose-containing textile materials is presented. High antimicrobial activity of biocidal products after washing was established. The duration of action and expediency of their use in the textile industry are proved. It is shown that after 10 washes the treated tissues lose only 14-15% of antimicrobial properties.

Fabrics are never ideally smooth. Their texture varies between fine and coarse, quantified through the surface’s vertical deviation. Fabric roughness, or its opposite smoothness, is employed as measure of the surface texture of fabrics. In general, texture depends upon fiber properties, yarn count, yarn twist, and fabric structure and fabric design). This research aims to determine the limitations in visual perception of surface roughness in comparison to objective surface roughness measurements of low weight polyamide fabrics. Subjective evaluation is used for the visual assessment, while instrumental measurement of the properties was conducted using a noncontact laser profilometer. Subjective evaluation was conducted by a panel of forty untrained evaluators on a sample of seven polyamide knitted fabrics with different yarn count and composition. The roughness profile parameters were measured using Talysurf CLI 500 according to ISO 4827. Although the surface roughness measured as arithmetic mean deviation (Ra) and roughness through visual inspection of the fabric are correlated, instrumental measurements of roughness are more precise. Differences in the surface roughness arising from significantly different yarn structures will be observed, while those due to the knitted fabric structure are negligible in visual inspection.

The study aims to investigate the ability of smart self-sensory carbon roving to detect damaged zones in TRC structures. State of the art monitoring procedures are based on integrative measurements and accordingly are limited in detecting only the occurrence of damage. This study aims to handle this limitation and offers to adopt the Time Domain Reflectometer (TDR) technique. The TDR concept is widely used in Bayonet Nut Coupling (BNC) cables to identify defects along the cable (opens, shorts, etc.). The current study adopts its principle to carbon rovings. To simulate the BNC cable configuration, the study offers to connect two parallel carbon rovings to the TDR Data Acquisition (DAQ) system. The proposed monitoring technique is investigated by loading two textile reinforced MPC beams under uniaxial tensile loading. Results show the potential of the suggested technique to locate damage zones in TRC structures and highlights its limitation.

Colour fastness is one of the important characteristics, which depends on the further effective and rational use of the potential fabric resource, durability, wear resistance, and the level of competitiveness in the market. Therefore, evaluating the light fastness of colours of cotton fabrics, in the wear of which sunlight plays a major role, is an urgent scientific task. Chenille cotton fabric, which is currently in demand by textile decorators and modern interior decoration, was chosen for the research. The research was carried out using methods of visual and instrumental colorimetry. The conducted research is valuable for providing information to the market and for further analysis and implementation of the process of developing a system technology for designing chenille cotton fabrics.

The paper features the rawhide collagen defibrillization process in the elastic leather materials manufacturing. Optimal colloid-chemical properties of semi-processed products were defined by way of using mathematical optimization of rowhide liming process. It was found that during the alkaline treatment of raw material (in the operating temperature range) the degree of defibrillation of raw material raises (in proportion to the derm collagen swelling) with increase in the ratio of process solution to the mass of raw material, and the extremum of hydrothermal stability and leather yield can be estimated. It was also shown that the degree of swelling decreases with a decreasing ratio of sodium sulphide and sodium hydrosulphide, and the leather area yield reaches the maximum value at the equal proportion of these reagents. Multicriteria optimization of rawhide liming process using the Harrington’s desirability function was carried out. The developed technology of soaking and liming was tested under production conditions. The above-mentioned low-waste technology provides elastic leather materials with a yield increase by 3.5%, which meet the industry standards requirements.

Numerical modelling, namely finite element modelling, is a standardised tool in many branches of engineering. In textile engineering, due to the complexity of the structure, many limitations occur in using this approach. Despite the limitations the finite element modelling of textiles has huge potential for the future. This contribution deals with FE modelling of tensile test in wale and course direction of single jersey knitted fabric. The meso level of the structure was chosen for the model, so it could be possible to track the behaviour of yarn interlacement during the simulated deformation. The virtual model was created according to parameters of single jersey knitted fabric sample, which was produced from polyester monofilament. By using monofilament instead of staple yarn, contacts between fibres in yarn could be excluded in FE model preparation. Two different computational programs were used for simulations – MSC Marc Metant for implicit computing approach and ANSYS LS-DYNA for explicit computing approach. The results from implicit and explicit solver were compared and discussed. Validation of models was done and results were included in the discussion. Due to big deformations of textiles, explicit solver appears to be more suitable for finite element modelling in textile engineering.
数值模拟，即有限元建模，是许多工程分支的标准化工具。在纺织工程中，由于结构的复杂性，使用这种方法存在许多局限性。尽管存在局限性，纺织品的有限元建模在未来仍有巨大的潜力。本文研究了平纹针织物纵向和纵向拉伸试验的有限元模型。该模型选择了结构的细观水平，因此可以跟踪纱线在模拟变形过程中的交错行为。根据涤纶单丝针织织物样品的参数，建立了虚拟模型。在制备有限元模型时，采用单丝代替短纤维，可以消除纱线中纤维间的接触。采用MSC Marc Metant隐式计算和ANSYS LS-DYNA显式计算两种不同的计算程序进行模拟。对隐式求解和显式求解的结果进行了比较和讨论。对模型进行了验证，并将结果纳入讨论。由于纺织品变形大，显式求解法更适合于纺织工程中的有限元建模。
