Problems solved by technology

Under alkaline conditions, the dyeing rate of spun silk fibers is very low, a large amount of dyestuffs are washed off by water, and the dyeing washed off by water stains cotton and spun silk, which not only affects the color fastness, but also stains the fibers and affects product quality

Embodiment 1

[0012] The sample specifications of lyocell, cotton and spun silk fabrics are: lyocell 20X spun silk 15 / cotton 85 30 116X78 +57 / 58, and the weight is 252g / ㎡. The above samples are dyed and finished by the following steps:

[0013] Pre-treatment: including desizing, scouring, bleaching and other processes: desizing adopts enzyme oxygen cold stack process, in desizing, add 2000L 10g of desizing enzyme per liter of water, 2g of chelating dispersant cm-5, wax remover 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.

[0014] Dyeing: The specific operation is: add water according to the bath ratio of 1:4-5 of the weight of the lyocell fiber to be dyed and the weight of the cotton and spun silk blended fabric, put the fabric into operation for 3 minutes, and then add neutral fixation at a temperature of 40°C Alkali-free reactive dyes—Kayacelon React dyes produced by Nippon Kayaku and ...

Embodiment 2

[0019] 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.

[0020] All the other are with embodiment 1.

Embodiment 3

[0022] 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 5.7 g, stabilizer 6 g.

[0023] All the other are with embodiment 1.

Abstract

The invention relates to a blended fabric dyeing and finishing technology, and particularly relates to a dyeing and finishing technology of a Lyocell and cotton and spun silk blended fabric. The invention aims at providing a dyeing condition capable of well coordinating Lyocell and cotton and spun silk to produce a high-quality product. The dyeing and finishing technology of the Lyocell and cotton and spun silk blended fabric comprises the processes of pretreatment, dyeing and the like; the pretreatment process comprises desizing and bleaching, wherein the desizing is performed by an enzyme-oxygen cold batch technology, and desizing enzyme, a chelating dispersant, a dewaxing agent and a refining agent are added in the desizing process; and 100% hydrogen peroxide and a stabilizer are added in the bleaching process. Through the invention, the problems of difficult color register and long technological flow are successfully solved; and through the method, the dyeing flow of the fabric is more reasonable, the production is clean and environment-friendly, and the product quality is stable.

Description

technical field [0001] The invention relates to a blended fabric printing and dyeing process, in particular to a dyeing and finishing process of lyocell fiber, cotton and spun silk blended fabric. Background technique [0002] Lyocell fiber and cotton spun silk fabric not only have lyocell fiber smooth feel, high strength, good drapability and dimensional stability, but also have good moisture absorption and breathability of cotton fiber, comfortable wearing and other properties, and also contain spun silk It has good water absorption and softness, and has a health care effect on the skin. The good characteristics of lyocell fiber, the hygroscopicity of cotton fiber, and the health care function of spun silk fiber are widely used in various clothing fabrics. This fabric meets people's pursuit of health, comfort and fashion. Consumer demand, deeply loved by consumers. However, since lyocell spun silk and cotton fibers have different structures and different dyeing properties...
