MAQOLA ANNOTATSIYASI

quote
In this work, the sorption, structural and hygienic properties of modified natural leathers treated with polymer compositions based on nitrogen-containing compounds with haloids were studied. It is shown that when natural leathers are treated with the developed polymer composition, the sorption properties are improved, and the images of electron microscopic studies also contribute to the emergence of more uniform dense structural elements, which contributes to an increase in the sorption of water vapor and an increase in the specific pore volume. The compaction of the leather structure during treatment with a polymer composition affects its hygienic properties.
