Abstract

The article examines the environmental aspects of finishing leather materials in the light industry using natural plant dyes. The relevance of the study is обусловлена высокой экологической нагрузкой традиционных процессов крашения, основанных на использовании синтетических химических веществ. The purpose of this work is to investigate the possibility of using extracts from local plant raw materials for environmentally safe dyeing of materials used in the production of footwear and leather goods. The objects of the study were sheepskin leather samples dyed with extracts of madder, oak bark, and zhuzgun (Calligonum aphyllum). The technology for obtaining plant extracts and the sequence of finishing operations are described. The strength properties of the dyed samples, including thickness, tensile strength, and elongation at break, were determined in accordance with the requirements of current standards. The research results showed that the use of natural plant dyes ensures uniform coloration of materials, preservation of structural homogeneity, and satisfactory strength characteristics of leather. The use of plant extracts makes it possible to reduce the chemical load on the environment and obtain environmentally safe materials that meet modern requirements for the sustainable development of the light industry.
