Influence of sorption and vapor permeability in providing normal conditions when operating hydrophobized footwear

Аннотация

hoes should provide normal conditions during the entire cycle of socks. In the work, the main objects for research were: acrylic emulsion A-1, polyvinyl ethinyl dihydroxychlorosilane, industrial oil IA-20, penetrator and widely used polyethyl hydrosiloxane. Based on them, a composition of water repellents was prepared in various initial ratios. Water repellents were prepared by sequentially mixing the above materials at a temperature of 20–22, ° C for 3-4 hours. It seems to us that in order to determine the role of sorption and permeability of materials in the implementation of moisture exchange processes, it is necessary to compare the amount of human skin's moisture loss while wearing shoes with the ability of the material to absorb moisture and remove it through vapor permeability.
