Abstract

Md. Ibrahim H. Mondal and Md. Mashiur Rahman Khan

Silk is a very fine, regular, translucent natural animal protein fibre. Raw and degummed silk fibres were dyed with extracted vegetable dyes such as catechu brown, waste dabshell and waste banana stem dyes mixed with Reactive Red 120. Silk fibre became more permanently even and bright when it was dyed with 2.0-3.0% of the mixed dyes. In each case, optimum conditions of dyeing were determined and fastness characteristics were studied.
