STUDY ON NATURAL DYEING OF SILK YARNS USING FERMENTED TURMERIC RHIZOMES WITH THEOBROMA CACAO FRAGRANCE

This study explores the use of a natural colouring method on silk strands. Before and after dyeing, the chemical composition changes in silk yarn are inspected using a Fourier-Transform Infrared Spectroscopy (FTIR) study. The outcomes showed that colourants and fragrances could be introduced to silk yarns without compromising their basic assembly. Physical examination of the yarns revealed that the natural dyeing method consumed no effect on breaking strength, only moderately increased elongation and colourfastness for staining, and barely altered other characteristics like nep count and unevenness. The significance of the naturally dyed fabrics increased as a result of the study's significant findings regarding the decrease of thin spots and the long-lasting retention of the Theobroma cacao scent.
