Dyeing Eri Silk Yarn with Soaked Red Beans Water

Abstract

The purpose of this research was to study on dyeing of eri silk yarn with soaked red bean water. Optimal condition for preparing dye solutions was 1:5 ratio of dried red bean to water and dyeing at 100°C for 45 min. The dyeing was conducted with and without mordants, using three different mordanting methods, pre-mordanting, meta-mordanting, and post-mordanting. Each mordant caused shade changes Ion dyed yarns and mordant techniques affected to color intensity and color fastness of dyed eri silk yarn.
