Abstract

The invention discloses a cashmere dyeing process utilizing natural vegetable dyes and cashmere products. The cashmere dyeing process utilizing natural vegetable dyes include the steps of washing of cashmere yarn, cationization of cashmere fiber, neutralization, primary soaping, dyeing, mordanting, secondary soaping, softening, dehydrating, and drying. Cashmere is modified through the special modification technology, and the fiber has cationized charge after being modified by a modifier; high-quality natural vegetable dyes of RAKUTO KASEI INDUSTRIAL CO., LTD. are adopted, are bonded with cationic groups on the cashmere fiber under action of different mordants, and the cashmere fiber is dyed with different colors naturally through deionized fixation. The cashmere products dyed with the natural vegetable dyes have the advantages that natural quality of cashmere is guaranteed, and additional value of products is increased; the textile has health function, is safe and comfortable to wear,is popular to world high-end brand buyers and top dress designers, and has good prospects.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a process for dyeing cashmere with natural plant dyes and cashmere products. Background technique [0002] From ancient times to the present, people have begun to use natural plant dyes to dye textiles, but only limited to cotton and wool products. At present, there are few papers on the use of natural plant dyes for cashmere dyeing, and this technology is still in the research and development stage. [0003] Cashmere is a rare special animal fiber. It is expensive as "diamond in fiber" and "soft gold". It is thin, light, soft, smooth and warm. Cashmere is different from wool. It presents irregular thin and deep curls. It is composed of scale layer and cortex layer. There is no medulla layer. The density of scales is about 60-70 / mm. The fiber cross section is approximately circular and the diameter is thinner than Wool is even finer, with an average fineness of 14-16 μm, a fin...
