The purpose. An investigation of the shielding effectiveness against electromagnetic radiation (EMR) by woven fabrics that are presented on the Ukrainian interior textile market. Methodology. Theoretical and experimental research is based on the general principles of textile materials science. The shielding effectiveness to EMR of textile fabrics was tested and measured using EM-2107A (Electro Metrics) in accordance with ASTM 4935-10 in the frequency range 30 MHz – 1.5 GHz. Results. Flexible screens based on textile materials are widely used for EMR shielding. The shielding effectiveness against EMR by textile materials can be improved with fabric modifying by metal fibers/threads, metal particles or conductive polymers at various stages of textile production. It possible to substantiate the expediency of using metal-containing textile materials as interior textiles on the result of carried out analysis of the modern assortment of interior textiles and the experimental studies. Studies results have shown that the proposed fabrics have a high shielding ability by the classification "professional use" according to FTTS-FA-003 Specified Requirements of Electromagnetic Shielding Textiles, the shielding efficiency of which is within 30 ÷ 60 dB. Scientific novelty. The expediency of using modern metal-containing textile materials as interior textiles for windows decoration has been substantiated. The studied textile materials make it possible to clarify a new promising segment of the interior textile market - windows decoration. The main goal of such textile - the decoration of the residential and administrative buildings is expanded and supplemented by the function of electromagnetic radiation shielding. Practical significance. The complex of scientific research on the shielding effectiveness against EMR allowed offering a new range of interior textile materials for window decoration.

Investigation of the influence of the peculiarities of raw material composition and structure of traditional and innovative linen textile materials on their hygienic properties. Theoretical and experimental investigations are based on the main positions of textile materials science. In experimental studies, modern standardized methods for determining the hygienic properties of textile materials were used, as well as techniques specially developed taking into account the peculiarities of the operating conditions of underwear. The peculiarities of the operating conditions and the basic functions of hospital underwear were determined. The comparative analysis of hygienic properties of traditional and modern fabrics for underwear was carried out. Using the standardized and the developed methods, adapted to the peculiarities of the conditions of use of the products, the indicators characterizing the processes of water absorption of the materials were experimentally determined. On the basis of the obtained values of quality indicators, a comprehensive assessment of the ability of materials to transfer moisture and air, with the calculation of the arithmetic complex quality index was done. This allowed to determine the material that is optimal in properties, which provides thermophysiological comfort when operating hospital underwear. Using the developed methods, which take into account the specifics of the operating conditions, a comparative analysis of the hygienic properties of traditional and innovative materials for underwear was carried out. A new range of textile materials for underwear has been proposed, taking into account the peculiarities of the operational situation of consumption.

Lead aprons that are lead-shielding products are generally used for personal protection of physicians and patients from X-ray (gamma) radiation during medical operations; lead has environmental disadvantages, with high toxicity, though. Therefore, the aim of this research was to produce an environmentally friendly and flexible textile-based radiation shielding material. In this work, 2/2 twill, 3/1 twill, Herringbone, Whipcord, which are twill derivatives, Barathea and Crêpe woven fabrics, which are sateen derivatives, woven with textured steel yarns, which have soft feeling and flexibility, and gamma radiation shielding effectiveness of these fabrics were investigated and were not studied in the references. The effects of fabric structural characteristics such as weave, conductive weft yarn density, fabric thickness and porosity on these properties were analysed graphically and statistically. It is observed that with the biggest thicknesses and lowest porosities, Barathea and Crêpe woven fabrics performed better gamma radiation shielding performance than other woven fabrics. The samples F1 and E1, woven with Barathea and Crêpe weave, have the highest gamma radiation shielding effectiveness, thanks to the highest fabric thicknesses and lowest porosities. In addition, the increases of textured steel yarn density improved the gamma radiation shielding effectiveness of woven fabrics.

Electromagnetic Shielding Effectiveness

Electromagnetic radiation is becoming increasingly serious around our living environment, which seriously endangers people's health and interferes with the operation of electronic equipment. The research and development of anti-electromagnetic radiation fabric have drawn more and more attention. However, the influencing rules and mechanisms of conductive fiber content, fabric tightness, warp–weft density, conductive yarn arrangement, weave type, and electromagnetic wave frequency on fabric electromagnetic shielding effectiveness have not been clarified. Therefore, in this study, a series of fabrics containing stainless steel fibers were produced. Meanwhile, the influencing rules of various factors on electromagnetic shielding effectiveness and the quantitative relationship between some factors and electromagnetic shielding effectiveness were discussed. The results showed that all factors had different degrees of influence on electromagnetic shielding effectiveness, and the relationship between electromagnetic shielding effectiveness and electromagnetic wave frequency could be approximately expressed as: [Formula: see text]. At the same time, the influencing mechanisms of various factors on electromagnetic shielding effectiveness were analyzed in combination with fabric microstructure and macrostructure, the intrinsic parameters of the fabric and the electromagnetic shielding effectiveness mechanism. The results are expected to provide a reference for the establishment of electromagnetic shielding fabric model and enterprise production.
