Abstract

The invention discloses a water-less dyeing method applicable to zippers and belongs to the technical field of dyeing and finishing of textiles. The dyeing method includes the steps of (1), winding ofzippers; (2), dyeing and washing; (3), dehydrating and drying to obtain the finished product. During dyeing, only a small amount of non-toxic dyeing promoter is added. Zero emission of sewage is achieved by application of the method, while dying uniformity and color fastness of disperse dyes can be improved effectively; besides, media can be recovered, so that ecological dyeing of zippers is realized in deed.

Description

technical field [0001] The invention relates to a waterless dyeing method suitable for zippers, without using a large amount of water, dispersant and carrier, reducing the degree of pollution, and realizing zero discharge of sewage, belonging to the technical field of textile ecological dyeing and finishing. Background technique [0002] In the past two years, my country's zipper enterprises have developed greatly, no matter in terms of the number, scale or development speed of enterprises, it is unprecedented. The zipper industry has encountered great opportunities for development, but challenges and crises also exist, and even the challenges are greater than the opportunities. Facing the pressure of environmental pollution, the entire industry will face losses and huge crises. [0003] The most important raw material for zippers is polyester. For zipper dyeing, polyester is mainly dyed with disperse dyes to obtain finished zippers. Taking polyester zipper dyeing with dispe...
