Abstract

The development of innovative, resource-efficient technologies for textile finishing — with a focus on utilizing local raw materials- — is a priority in modern industrial development. In this context, replacing expensive imported synthetic dyes with natural alternatives derived from secondary resources, food industry waste, and local flora represents a viable and economically sound approach. Ensuring the environmental sustainability of the technological process is of particular importance when dyeing natural silk with natural dyes. This, in turn, facilitates the production of high-quality textile goods that meet modern contemporary environmental standards and encompass a wide range of items, -including branded national products, souvenirs, exclusive goods, and interior textiles. Given the lack of domestic synthetic dye production, the use of natural dyes derived from local flora rich in pigment-yielding plants and from secondary resources is becoming an especially relevant and sought-after solution, particularly from an environmental protection perspective. This paper presents the results of developing a method for dyeing natural silk with a natural dye derived from black elderberry. The study investigated investigates the effect of mordant salts(CuSO₄, KAl(SO₄)₂, K₂Cr₂O₇, Fe₂(SO₄)₃, Ni(NO₃)₂, CoCl₂, Al₂(SO₄)₃, SnCl₂) on the quality and color characteristics of natural silk samples. The research aims to provide a scientific basis for an environmentally safe textile production technology that ensures high quality and resource conservation while reducing wastewater contamination by aniline compounds associated with synthetic dyes.
