Problems solved by technology

[0004] 1. Dyeing in overflow dyeing machine or high-temperature and high-pressure dyeing machine, adopting 130°C one-bath dyeing process; the disadvantage of this method is: the color of reactive dyes on the cotton viscose position becomes relatively dim, which cannot meet the needs of home textiles. The product requires bright colors;
[0005] 2. The hot-melt machine first dyes disperse dyes at 190-220°C, and then over-dyees reactive dyes; the disadvantage of this method is that the processing process is too long, and for cotton / viscose and acetate interwoven fabrics such as interwoven jacquard multi-component distribution , due to the difference in fiber shrinkage properties during the production process, the process is long and easy to wrinkle
[0006] The above two methods are high-temperature treatment, and it cannot be produced without high-temperature equipment, which limits the production process of fabrics
In addition, acetate fiber is not resistant to high temperature, high temperature processing will lead to stiff hand feeling, and lead to heavy staining of blended cotton and viscose fiber
The current dyeing and finishing process for cotton / viscose and acetate interwoven fabrics cannot take into account the convenience of production and energy saving and emission reduction. At the same time, the hand feeling and color brightness of the dyed fabrics obtained are not very ideal.

Abstract

The invention provides a cotton / viscose glue and acetate mixed fabric dyeing and finishing process. The dyeing and finishing process is carried out in a jig and comprises steps of: fabric pretreatment, dyeing processing and fabric aftertreatment. The fabric pretreatment comprises steps of: singeing, desizing and bleaching. The fabric aftertreatment comprises steps of: softening and sizing, calendaring and shrinkage. According to the invention, cotton / viscose glue and acetate fiber mixed fabric is dyed by a mesothermal one-bath one-step method. Colors are not mutually stained. The process provided by the invention has advantages of differential dyeing, simple equipment requirement, simple and feasible process and color control, energy saving and emission reduction and green and environmentally friendly dyeing and finishing processing. By the adoption of the process, fabric design style, color, pattern effects are fully presented, variable-pigment stereo effect of high-grade cotton / viscose glue / acetate fiber mixed figured cloth is highlighted, novelty is increased, and novel fabric dyeing and finishing matching technology requirements and market requirements are met.

Description

technical field [0001] The invention relates to the field of preparation of textile printing and dyeing chemicals, in particular to a dyeing and finishing process of cotton / viscose and acetate fiber interwoven cloth. Background technique [0002] At present, cotton viscose fiber is generally dyed with reactive medium temperature or reactive low temperature, and acetate fiber is generally dyed with disperse dyes at high temperature. Cotton / viscose and acetate interwovens are usually dyed with disperse / reactive dyes. [0003] There are two ways of conventional disperse / reactive dye dyeing: [0004] 1. Dyeing in overflow dyeing machine or high-temperature and high-pressure dyeing machine, adopting 130°C one-bath dyeing process; the disadvantage of this method is: the color of reactive dyes on the cotton viscose position becomes relatively dim, which cannot meet the needs of home textiles. The product requires bright colors; [0005] 2. The hot-melt machine first dyes dispers...
