Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: because the rayon fabric is not treated with anti-wrinkle treatment, the garments made of this fabric are prone to wrinkles. In order to maintain the crispness of the clothing, it is often necessary to iron the clothing. hot, resulting in poor wearing performance of the fabric

Embodiment 1

[0063] The dyeing and finishing process of a kind of rayon fabric disclosed by the invention specifically comprises the following process steps:

[0064] S1: Singeing, specifically singeing the fabric with a singeing machine to obtain a singeed gray cloth.

[0065] S2: Pretreatment, that is, descouring, bleaching, mercerizing, and presetting are performed on the burnt gray cloth obtained in step S1, so as to obtain a pretreated gray cloth.

[0066] S3: non-ironing finishing, specifically taking the pre-treated gray cloth obtained in step S2, putting it into the non-ironing modified solution for padding, the specific process of padding is as follows, the excess rate of padding is 85%, and the padding is completed The final gray cloth is dried at 80°C for 3 minutes, and then the preliminarily dried gray cloth is baked at 160°C for 3 minutes. After the baking is completed, the gray cloth is stacked for 24 hours to obtain a non-ironing gray cloth.

[0067] Wherein, the non-iron m...

Embodiment 43

[0114] The difference between Example 43 and Example 1 is that no hydrophobic treatment is performed between Step S4 and Step S5, that is, the post-treatment of Step S5 is directly performed on the pad-dyed gray fabric obtained in Step S4.

Abstract

The invention relates to a dyeing and finishing process of rayon fabric, and belongs to the technical field of dyeing and finishing processes. The dyeing and finishing process comprises the followingprocess steps of S1, singeing, wherein singeing grey cloth is obtained; S2, pretreatment, wherein, specifically, the singeing grey cloth obtained in the step S1 is subjected to pretreatment, and pretreatment grey cloth is obtained; S3, non-ironing finishing, wherein, specifically, the pretreatment grey cloth obtained in the step S2 is taken to be placed into non-ironing modification liquid to be subjected to padding, the padding rate ranges from 85% to 90%, then the grey cloth obtained after padding is dried for 3-5 min at the temperature ranging from 80 DEG C to 90 DEG C, the grey cloth obtained after preliminary drying is baked for 2-3 min at the temperature ranging from 150 DEG C to 160 DEG C, the baked grey cloth is piled for 18-24 h, and non-ironing grey cloth is obtained;S4, pad dyeing, wherein, specifically, the non-ironing grey cloth obtained in the step S3 is subjected to pad dyeing, and pad dyeing grey cloth is obtained; and S5, aftertreatment, wherein, specifically, the paddyeing grey cloth obtained in the step S4 is subjected to aftertreatment, and finished grey cloth is obtained. The process has the effect that the non-ironing performance of the fabric can be improved.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing processes, in particular to a dyeing and finishing process for rayon fabrics. Background technique [0002] Rayon, also called artificial cotton or viscose fiber, referred to as viscose fiber, is a cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose with "wood" as the raw material. The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It has the characteristics of smooth and cool, breathable, antistatic, anti-ultraviolet, colorful and good color fastness. It has the essence of cotton and the quality of silk. It is an authentic plant fiber, derived from nature and superior to nature. Widely used in various underwear, textile, clothing, non-woven and other fields. However, rayon also has natural disadvantages. One of the most important disadvantages is that it is prone to wrinkles, which makes the rayon fa...
