The Optimized Analysis of the Dyeing Property of Coptis Chinensis towards Natural Bamboo Fiber

Abstract

The paper researches the dyeing property of coptis chinensis and bamboo fiber through orthogonal experimental analysis and single factor comparative analysis, gets the optimized process of direct dyeing, pre- mordant dyeing, one-bath dyeing and post-mordant dyeing, as well as tests and compares the dyeing fastness and fracture tensile property of the optimized process of the four dyeing methods.
