Abstract

The invention discloses a polyester-nylon-woven elastic fabric and a producing method thereof. The elastic fabric is deep dyed, warp yarns are nylon fibers, weft yarns are polyester bicomponent elastic fibers, and an L value ranges from 10 to 18. One bath dyeing is adopted, the pH value of the dyeing bath is adjusted twice, deep dyeing effect of the finished product is optimized well, and incidence of dyeing defects is reduced.

Description

technical field [0001] The invention relates to a textile, in particular to a polyester-nylon interwoven elastic fabric which can be dyed in thick colors and a production method thereof. Background technique [0002] At present, elastic fabrics on the market are mainly divided into two categories: one is elastic fabrics containing spandex core-spun yarn, such as polyester / spandex core-spun yarn. This kind of product has been favored by people because of its high elasticity and excellent rebound performance. However, spandex is not resistant to high temperature, chlorine bleaching and susceptible to microbial attack. It is also well known, especially the dyeability of spandex. It has always been a big problem in the industry. There have been related literatures reporting the relationship between the dye structure and the dyeability of spandex. It was found that the dyeability of spandex fibers to dyes of different structures is very different, and the dyeing rate of disperse...
