- Abstract
Aiming at solving the problem that color fastness to light and to washing of cashmere fibers dyed with rubia plant dyes was lower than grade 3 and color repeatability is poor, cashmere fibers were dyed by alum pre-mordant dyeing method. Test results show that when alum pre-mordant dyeing is used, pH value of dye solution is 4.0-4.5, concentration of alum mordant is 0.5-1. 0 g/L, and dosage of rubia plant dyes is lower than 0.5%(owf), dye solution can be almost absorbed, color reproduction is good, and the hand feeling of cashmere fiber is not affected. Color fastness to both light and washing is improved by more than 0.5 grade. Hand feeling of cashmere after mordant dyeing can be improved by using wool protectant. Color shade change of cashmere before and after mordant dyeing is less than that of alum mordant dyeing. Through the study of pre-mordant dyeing method and process conditions, this paper provides a reference for the implementation and control of cashmere plant dyeing products.
