“…17 Thus, summarising the results of the data obtained, according to a comparative assessment of the effects of the existing and proposed methods of WHT of sewing parts, it can be stated that when processing textile material with the existing WHT method, the indicators of fabric thickness, breaking load, and breathability decrease on average by 32.9%, 21.41%, and 22.51%, respectively. Considering the importance of such properties of textile materials as fabric thickness, breaking load, and breathability for ensuring the quality of manufacturing of clothing parts, it can be concluded that the use of a vacuum installation allows maintaining the specified properties of the materials used [17].…”

Relevance. Investigation in the field of textile materials and the effect of processing on their properties, is relevant, as it helps to develop more effective processing methods and increase the resistance of textile materials to the influence of various factors, which is important for both manufacturers and consumers. Purpose. The purpose of the study was to examine the effect of hydrothermal processing of textile materials on their physical and mechanical properties, develop a technology for the production of clothing using a new method (device) of press equipment for hydrothermal processing of composite material. Methodology. The analysis method was used during the study, and an experiment was also conducted in which the temperature of the steam that did not fall below 160°C was used when processing the selected fabric samples, and the temperature of the working bodies of the press for forming the back was at least 110°C. Results. As a result, the influence of hydrothermal treatment on the properties of textile materials was examined in detail and established. Having analysed the existing method of hydrothermal treatment using a vacuum unit, it was established that the conventional method of treatment leads to a substantial decrease in fabric thickness, breaking load and air permeability. It was also noted that during the hydrothermal treatment of the material, it is exposed under the influence of pressure. This leads to densification and flattening of the threads inside the material, creating flat areas, which causes adverse changes in the physical and mechanical characteristics of the fabric. Conclusions. These factors indicate a potential deterioration in the quality and durability of textile products, which can increase the percentage of defects and negatively affect consumer satisfaction. This study also points to the prospects of using a vacuum installation in hydrothermal treatment, which allows preserving the desired properties of materials, improving the quality of the final products. The practical importance of the results of this study lies in the possibility of improving the quality of textile products and reducing the damage to materials, which is important for ensuring longer operation of textile products and increasing consumer satisfaction

“…The masks were processed as a whole (three layers) and each layer separately. Air permeability was evaluated according to GOST ISO 9237-2013 on an A0003-PC instrument (IDM Instruments, Australia) at a pressure drop of 100 Pa, sample area 20 cm 2 . The water vapor penetration rate (vapor permeability) was determined on a UTX-3100 device (Textest AG, Switzerland) (test area 0.3 cm 2 , t = 25.50 °C).…”

“…Nonwoven materials are raw materials for the production of disposable medical products: clothes, underwear, masks [1,2]. In the context of the coronavirus pandemic and the impossibility of quickly producing a large number of medical masks, the task of developing sterilization technologies for medical masks and respirators is relevant.…”

The paper considers the influence of plasma flow of a high-frequency capacitive discharge at reduced pressure (as a potential sterilization tool) on the main physical and mechanical characteristics of a three-layer medical mask (spunbond-meltblown-spunbond). The treatment was carried out using argon and air as plasma-forming gases. It is shown that the breathability of the mask determines (limits) the breathability of the middle layer (meltblown). Plasma treatment in the modes under consideration does not significantly affect the air permeability and mechanical tensile strength of the composite layers of the mask. There is a slight increase in vapor permeability, an increase in the hygroscopic properties of the middle and inner layers, which indicates an improvement in the hygienic characteristics of the mask, but at the same time, the hydrophobicity of the outer layer is preserved. When plasma is used to sterilize medical masks, bacterial filtration efficiency and microbiological purity will be the main deciding factor.

“…An example is food waste containers, which are more convenient to throw away with their contents. Or, for example, disposable nonwoven products for hygiene (diapers, feminine hygiene products, napkins for various purposes) are also difficult to recycle and, as a rule, are only disposed of [13][14][15][16].…”

The use of thermoplastic starch in compositions based on polylactic acid is of interest from the point of view of controlling the physicomechanical properties of materials and the time of biodegradation. The effect of thermoplastic starch containing sorbitol and / or glycerin as plasticizers on the resistance of compositions based on polylactic acid to thermal and thermomechanical action was studied. The physicomechanical properties of the compositions and their resistance to biodegradation under composting conditions have also been determined.
