Embodiment 1

[0026] The process of dyeing and finishing wool and polyester fabrics includes the following steps:

[0027] Pre-treatment: adopt continuous pad dyeing equipment, including desizing, bleaching and other steps: desizing adopts enzyme desizing process, in desizing, add 2000L10g of desizing enzyme per liter of water, 2g of chelating dispersant cm-5, wax removal The agent WR is 4g, the refining agent 88ECO is 4g; in the described bleaching process, 5.5g of 100% hydrogen peroxide and 7g of stabilizer are added per liter of water.

[0028] Shaping: Shaping the pre-treated fabric, the shaping process conditions are: temperature 200°C±1°C, time 25-30 seconds.

[0029] Dyeing: The specific operation is: add water according to the bath ratio of 1:4-5 of the weight of wool and polyester fabric to be dyed, put the fabric into operation for 3 minutes, add dyeing auxiliaries, acetic acid and disperse dyes in sequence, Add 3mL of acetic acid into the water so that the pH value of the dyeing...

Embodiment 2

[0033] In the pretreatment process, add 2000L9g 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 per liter of water 6g, stabilizer 8g.

[0034] All the other are with embodiment 1.

Embodiment 3

[0036] In the pretreatment process, add 2000L11g of desizing enzyme per liter of water during desizing, 1.5g of chelating dispersant cm-5, 5g of wax remover WR, and 3g of refining agent 88ECO; in the bleaching process, add 100% hydrogen peroxide per liter of water 5g, stabilizer 6g.

[0037] All the other are with embodiment 1.

Abstract

The invention belongs to the technical field of wool polyester drying and sliver-mixing, and particularly relates to a wool polyester drying and sliver-mixing method, including the processes such as pre-processing, sizing, dyeing and after-finishing. The process of pre-processing includes desizing and bleaching, wherein a desizing enzyme, a chelating dispersant, a wax remover and a refiner are added in the desizing process, and 100% of hydrogen peroxide and stabilizer are added in the bleaching process. From optimization of the processes of pre-processing, to screening of dyestuff and additives, and to optimization of the after-finishing, a great quantity of development experiments are performed, and problems about difficulty in color topping and long flow are solved successfully finally.By the method, dyeing of fabric is reasonable, production of fabric is clean and environmentally friendly, products have stable quality, and the wool polyester fabric is high graded, comfortable, fashionable, green and environmentally friendly, and has differential styles; the wool-series casual fabrics which come into the market for customers fill in gaps of domestic or international markets effectively, and are a great innovation in spinning, weaving, dyeing and finishing.

Description

technical field [0001] The invention relates to the technical field of drying and mixing wool polyester slivers, in particular to a method for drying and mixing wool polyester slivers. Background technique [0002] Wool and polyester fabrics not only have good moisture absorption and breathability, but also have the advantages of good elasticity of wool, high wear resistance, high fiber density, high strength, and high temperature resistance of polyester polymers. They are widely used in various clothing fabrics and are well received. Consumers love it. 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. [0003] In order to solve the above problems, this application proposes a method for drying and mixing wool polyester. Contents of the invention [0004] (1) Purpose of the invention [0005] In order to solve the ...
