Problems solved by technology

[0004] From the analysis of the actual test results of mass production, after dyeing with high temperature and high pressure disperse dyes, the color fastness of polyester fiber dyeing is better after reduction cleaning. The main technical problem is that the color fastness of cotton fiber is poor, especially the color fastness to washing and staining. , the customer's quality requirements are 3~4 grades, sometimes the product's fastness is only 2~3 grades, which cannot meet the quality standards, which restricts the development of production

Abstract

The invention discloses a bright red dyeing method of a polyester-cotton interwoven product and belongs to the technical field of polyester-cotton interwoven product dyeing. The method is characterized in that in the color registering step, a dye is fully and evenly stirred and dissolved in an auxiliary cylinder in advance, no dye particles exist, the dye is added into a dye jar and heated to 60 DEG C for constant-temperature dyeing, dyeing is conducted twice, anhydrous sodium sulphate powder with the concentration of 80 g/L is added in the third dyeing process and the fourth process in twice, alkaline powder with the concentration of 20 g/L is added in the seventh dyeing process and the eighth dyeing process in twice, constant-temperature dyeing continues for ten times, soaping, water washing and acid pickling are conducted, and the product is wound and taken out of the dye jar. The cotton fiber active dye is selected, so dye absorption of cotton fibers is improved, the deep dyeing property is good, lifting force is high, dye consumption is small, reactivity between the dye and the fibers is improved, flooding of fiber surfaces is eliminated, and color fastness is improved.

Description

technical field [0001] The invention discloses a bright red dyeing method of polyester-cotton interwoven products, which belongs to the technical field of dyeing polyester-cotton interwoven products. Background technique [0002] The wide-width polyester-cotton interwoven jacquard product is bright red, passionate and festive. It is mainly used to make wedding bedding sets and is very popular among consumers in the market. [0003] Polyester-cotton interwoven jacquard products refer to the warp thread is polyester fiber, the weft thread is pure cotton fiber, the two fibers are interwoven, the common weave specification is 100d×32s / 2 173×60, the warp thread is 100d stretch textured yarn dty, and the weft thread is 32s Combed cotton plied yarn. Polyester-cotton interwoven jacquard products are dyed in bright red, produced in jiggers, using disperse dyes to dye polyester fibers at high temperature and high pressure, commonly known as "priming" color, jigging reactive dyes at r...
