Structural and Performance Characteristics of Pigskin Leather with Different Tanning Methods

摘要

This article studies the influence of mineral and organic tanning methods on a set of physico-mechanical, thermophysical and hygienic properties of pigskin. The dialdehyde method of tanning with subsequent anionic polymer filling provides the formation of a homogeneous porous structure of leather in various topographical areas with the necessary set of structural and performance characteristics. The described tanning technologies provide the formation of leather with appropriate hydrothermal resistance and adequate elastic-plastic properties. It meets the standard requirements for garment leather DSTU 3115-95. The resulting leather can be recommended for the manufacture of wide range goods, including chrome tanned for spring-summer goods and the dialdehyde tanned for autumn-winter goods.
