Embodiment 1

[0014] Dyeing and finishing of wool and recycled polyester blended fabrics, the process includes the following steps:

[0015] Pre-treatment: adopt continuous pad dyeing equipment, including desizing, bleaching and other steps: desizing adopts enzyme desizing process, in desizing, add 2000L 10g of desizing enzyme per liter of water, chelating dispersant Wax WR is 4 g, refining agent 88ECO is 4 g; in the bleaching process, 5.5 g of 100% hydrogen peroxide and 7 g of stabilizer are added per liter of water.

[0016] Shaping: Shaping the pre-treated fabric, the shaping process conditions are: temperature 200°C±1°C, time 25-30 seconds.

[0017] Dyeing: The specific operation is: add water according to the bath ratio of 1:4-5 of the weight of wool and recycled polyester blended fabric to be dyed, put the fabric into operation for 3 minutes, add dyeing auxiliaries, acetic acid and disperse dyes in sequence The amount of acetic acid added per liter of water is 3mL, so that the pH val...

Embodiment 2

[0021] In the pretreatment process, add 2000L 9g of desizing enzyme per liter of water during desizing, 2.5g of chelating dispersant cm-5, 3g of wax remover WR, and 5g of refining agent 88ECO; in the bleaching process, add 100 % hydrogen peroxide 6 g, stabilizer 8 g.

[0022] All the other are with embodiment 1.

Embodiment 3

[0024] In the pre-treatment process, add 2000L 11g of desizing enzyme per liter of water, 1.5g of chelating dispersant cm-5, 5g of wax remover WR, and 3 g of refining agent 88ECO; in the bleaching process, add 100 % hydrogen peroxide 5 g, stabilizer 6 g.

[0025] All the other are with embodiment 1.

Abstract

The invention relates to dyeing processes of blended fabric, in particular to a dyeing and finishing process of blended fabric of wool and recycle polyester, and aims to provide the dyeing and finishing process capable of coordinating dyeing conditions of wool and polyester to produce high-quality blended fabric. According to the technical scheme, the dyeing and finishing process includes pretreating, setting, dyeing, post-treating and the like. The pretreating includes desizing by adding desizing enzyme, chelating dispersant, dewaxing agent and refining agent and bleaching by adding 100% hydrogen peroxide and stabilizer. The problems of overdye difficulty and long process flow are solved. By the process, dyeing flow of the fabric is more reasonable, production is clean and environment-friendly, and product quality is stable.

Description

technical field [0001] The invention relates to a blended fabric printing and dyeing process, in particular to a wool and recycled polyester blended fabric dyeing and finishing process. Background technique [0002] Wool and recycled polyester fabric not only has good moisture absorption and breathability, but also has the advantages of good elasticity of wool, high wear resistance, high fiber density of polyester polymer, high strength, high temperature resistance, etc. It is widely used in various clothing fabrics, and is deeply Loved by the majority of consumers. However, because polyester and wool fibers have different structures and different dyeing properties, dyeing often brings problems such as color registration difficulties and long process flow to enterprises. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing and finishing process of wool and recycled polyester blended fabrics that can solve the above problems, a...
