Abstract

Disclosed is a polyester and polyamide compound fine denier fabric dyeing method. The polyester and polyamide compound fine denier fabric dyeing method comprises the following steps of splitting and soda boiling, dyeing, reductive soaping and drying. Compared with the prior art, the polyester and polyamide compound fine denier fabric dyeing method obtains good dyeing stability. Polyester and polyamide fiber fabric obtained through the polyester and polyamide compound fine denier fabric dyeing method is uniform in dyeing and avoids dyeing mess and accordingly obtains excellent performance.

Description

technical field [0001] The invention relates to the technical field of textile chemical industry, in particular to a method for dyeing polyester-nylon composite fine-denier fabrics. Background technique [0002] Polyester-nylon composite fiber is formed by melt-spinning in a certain proportion in the production process by utilizing the difference in chemical structure of PET and PA6 polymers, and their weak interfacial bonding force, which can be separated from each other. Polyester-nylon composite fibers with different characteristics determine the difference in dyeing, and are also likely to cause differences in dyeing rate. As a result, polyester-nylon composite fiber fabrics are easy to be dyed. Therefore, controlling the dyeing rate is one of the keys to dyeing superfine fiber fabrics with disperse dyes, which also makes the dyeing of polyester-nylon composite fiber fabrics more complicated than single-component pure polyester fabrics or pure nylon fabrics.
