Problems solved by technology

In the traditional dyeing process, the spandex in polyester-spandex and nylon-spandex is basically not colored. Even if it can be dyed, the fastness is very poor and it is not washable. Especially when the spandex content is high, the color fastness of the fabric cannot meet the requirements. Require

Embodiment 1

[0014] The dyeing process of a polyester-spandex four-way stretch fabric involved in this embodiment comprises the steps of: pre-dyeing the polyester-spandex four-way stretch fabric, dyeing the polyester-spandex four-way stretch fabric, reducing and cleaning the dyed fabric, and dyeing the polyester-spandex four-way stretch fabric. Foam hold for fabric.

[0015] In step S1 before dyeing, the polyester-spandex four-way stretch woven fabric is selected, the content of spandex is 15%-25%, and the warp and weft yarns are all polyester spandex core-spun yarns. The warp and weft yarns used in the selected polyester-spandex four-way stretch fabric are both 150D+40D.

[0016] Inject clean water according to the selected fabric at a bath ratio of 1:15, and add ULTRAVON TC, INVATEX CRA, INVADINELUN, INVATEX KR HC, RUCOGEN WBL, and caustic soda.

[0017] ULTRAVON TC is Huntsman's high-efficiency, multi-purpose detergent, dispersant and detergent with strong wetting performance. Low foa...

Abstract

The invention discloses a dyeing process for a dacron-spandex all-around elastic fabric. The dyeing process comprises the following steps: S1, pre-treatment of dyeing: selecting a dacron-spandex all-around elastic woven fabric, wherein the content of spandex is 15-25%, and carrying out pre-treatment of dyeing on the fabric; S2, dyeing: adding soft water into a dye vat according to a bath ratio of1: 20 at room temperature and adding a penetrant, a color fixer, a leveling agent, a pH value regulator, a spandex accelerant, an acidic dye, a dispersive dye, a fiber protecting agent and a diffuserinto clean water; S3, reductive cleaning: a cleaning liquid contains caustic soda, sodium hydrosulfite, a cleaning agent and hydroxymethyl sulfonate and S4, foam setting. The invention relates to thedacron-spandex all-around elastic fabric. Compared with a conventional process, the high spandex content dacron-spandex all-around elastic fabric has same dyeing depth in uniformity of dacron-spandexdyeing. The dyeing effect to spandex is better than that of the conventional process, and the washed fabric does not change color and fade away and is relatively good in color fastness.

Description

technical field [0001] The invention relates to the technical field of textile fabric dyeing, in particular to a dyeing process of polyester-spandex four-sided elastic fabric. Background technique [0002] Spandex fabric is popular with consumers due to its excellent elasticity. Spandex is often mixed with other fibers into twisted yarn or core-spun yarn, which is used in various warp knitting, weft knitting and woven fabrics; but on the other hand, spandex Due to its unique structure, no special dyes can be dyed. In the traditional dyeing process, the spandex in polyester-spandex and nylon-spandex is basically not colored. Even if it can be dyed, the fastness is very poor and it is not washable. Especially when the spandex content is high, the color fastness of the fabric cannot meet the requirements. Require. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing process of polyester-spandex four-sided elastic fabric, which can m...
