Abstract

The invention provides a dying method for cotton / cashmere blended yarn, which sequentially comprises pre-treatment, dying, post-treatment and oven-drying. The method is characterized in that the pre-treatment process comprises enzyme scouring treatment and oxygen bleaching treatment, and the dying process is achieved by bath dying using an active dye. The invention can effectively solve the problems of influencing the dying quality of cotton / cashmere blended product, such as dyeing defect and poor level dyeing property occurred in bath dying process as well as poor homochromatic property in cotton and cashmere dying, thus achieving better effect.

Description

Technical field [0001] The invention provides a method for dyeing cotton / cashmere blended yarn, in particular to a process for dyeing cheese and warp beams with reactive dyes. Background technique [0002] Cashmere is a precious and rare special animal fiber in the world and a high-grade raw material for the textile industry. It is known as "fiber diamond" and "soft gold". Soft to the touch, plump suede, good warmth retention, strong hygroscopicity, natural and soft luster, comfortable to wear and other features combined to give people a luxurious and elegant feeling. Consumers can gain warm enjoyment and elegant demeanor after wearing it It is an ideal product for people to pursue high-end and perfect clothing. Cotton / cashmere blends combine the advantages of both cotton and cashmere fibers, and are one of the best blended fibers for high-end clothing fabrics. On the problem of the same color of cotton and cashmere dyeing, the two-bath method is usually adopted. Cashmere ...
