Dyeing and finishing process of black polyester-cotton elastic fabric

Abstract

The invention discloses a dyeing and finishing process of a black polyester-cotton elastic fabric, and belongs to the technical field of fabric dyeing and finishing. The dyeing and finishing process comprises the following steps of padding the black polyester-cotton elastic fabric in a treating fluid at normal temperature, then immersing the black polyester-cotton elastic fabric in an enzyme treating fluid, pre-setting the thermally washed and dried fabric, and then carrying out reduction cleaning, cotton dyeing and soaping and fixation: putting dyed polyester and cotton into a fixation jar, adding 2 g / L of a soaping agent and 2 g / L of a dedusting agent, performing continuous soaping twice at 98 DEG C for 20 minutes, performing cleaning, adding 3 g / L of a formaldehyde-free fixing agent, performing fixing for 20 minutes at the temperature of 40 DEG C, and taking out the fabric from the jar; and performing final setting: performing heat setting on the elastic fabric subjected to soaping and fixing in a heat setting machine at 120-130 DEG C, wherein the cloth feeding speed ranges from 25 m / min to 30 m / min, and the set fabric width is 2-3 cm greater than the finished fabric width. The process is good in fixation and relatively deep in dyeing, and meets market requirements.

Description

technical field

[0001] The invention belongs to the technical field of elastic fabrics, in particular to a dyeing and finishing process of black polyester-cotton elastic fabrics. Background technique

[0002] Polyester-cotton is a mixture of polyester and cotton, with polyester as the main component. Polyester-cotton blends are textiles made of polyester as the main component, using 65% polyester and 35% cotton blended yarn. Polyester-cotton cloth is commonly known as Dacron. It is not as comfortable as cotton, and it is not as sweat-absorbing as cotton. Polyester is the largest variety with the highest output among synthetic fibers. Polyester has many trade names, "polyester" is the trade name of our country, and its chemical name is polyethylene terephthalate, which is usually polymerized by chemicals, so polyester is also called polyester. Structure and performance: The structure shape is determined by the spinneret hole, and the cross-section of conventional polyester ...
