Влияние неравновесной низкотемпературной плазмы на потребительские характеристики спанмелт-материала

Abstract

Nonwovens (nonwovens) are widely used in medicine, for the manufacture of medical linen, sanitary and hygienic items, medical clothing, surgical materials (including dressings). The rapid development of the clothing market requires domestic manufacturers to be competitive not only through new products and technologies, but also new sensations for the consumer, provided that the price is competitive. According to medical workers, disposable surgical gowns based on spunmelt materials give a feeling of discomfort during use. One and relatively new method for modifying nanomaterials is treatment with nonequilibrium low-temperature plasma (NLTP). The main advantage of this type of material modification is the environmental friendliness of the method, as in the process of processing aqueous solutions of chemicals are not used, as in the case of using special impregnations. Modern research of medical services. As a result of the work, it was revealed that the modification of NM NNTP allows you to change the NM for changes in surface, physical and mechanical, as well as consumer properties, while maintaining the strength characteristics. It is shown that after plasma treatment spunmelt materials increase such consumer characteristics as air permeability, hygroscopicity, while maintaining the strength during elongation; reduction of material stiffness during bending. It was also found that after the processing of NTPP, the electrification rate increases within the normal range, in GOST 12.1.045-84. Manufacturers are recommended to process spunmelt material with non-equilibrium low-temperature plasma on a high-frequency capacitive plasma installation with a power of Wp = 1.5 kW, processing time τ = 180 s and pressure P = 21.5 Pa. Use argon gas with a gas flow of 1500 cm3/min as a plasma-forming gas.
