Problems solved by technology

However, disperse dyes have high affinity to spandex and good dyeability. At the same time, disperse dyes dyed on spandex can easily migrate out of spandex fibers, thereby affecting the overall color fastness of crystal linen. Therefore, it is urgent to provide A Dyeing Process for Improving the Color Fastness of Crystal Linen Fabric

Embodiment 1

[0038] refer to figure 1 , a dyeing process of crystal hemp fabric, the following steps are performed on the gray cloth: wherein the gray cloth is composed of 92% polyester and 8% spandex.

[0039]S1: pre-processing. The gray cloth is transported to the wrinkle removal machine for processing, the temperature in the wrinkle removal machine is adjusted to 180°C, and the wrinkle removal treatment is continued for 15 minutes.

[0040] S2: Pre-shrunk. The gray cloth after S1 treatment is transported to the high temperature and high pressure overflow dyeing machine, and then caustic soda solution is added into the high temperature and high pressure overflow dyeing machine for preshrinking treatment. The concentration of caustic soda is 1g / L, and the temperature is controlled at 110°C. for 2h.

[0041] S3: Initial washing. Rinse the gray cloth after S2 pre-shrinking with clean water for 10-15 minutes.

[0042] S4: Staining. Dyeing the gray cloth after the initial water washing ...

Embodiment 6

[0050] The difference between embodiment 6 and embodiment 1 is that there is no fatty alcohol polyoxyethylene ether and babassu oleamidopropyl betaine in the raw material of the dye used for dyeing in S4 dyeing.

Embodiment 7

[0051] The difference between Example 7 and Example 1 is that there is no ammonium polyacryloyl dimethyl taurate, fatty alcohol polyoxyethylene ether and babassu oleamidopropyl betaine in the raw materials of the dye used in the dyeing of S4.

[0052] The difference between embodiments 8-11 and embodiment 1 is that the raw materials of the reduction cleaning agent in S5 washing again are as shown in table 2 in parts by weight: unit: part

Abstract

The invention relates to the technical field of textiles, and discloses a dyeing process of a crystal linen fabric. The dyeing process is characterized by comprising the following steps of S1, carrying out pretreatment; S2, carrying out pre-shrinking; S3, carrying out primary washing; S4, carrying out dyeing, namely dyeing the grey cloth after being treated in the S3, wherein a dye used for dyeingcomprises the following raw materials in parts by weight of 25-45 parts of disperse dye, 20-30 parts of dispersant MF, 15-25 parts of ammonium sulfate, 25-45 parts of fatty acid methyl ester polyoxyethylene ether sulfonate and 5-10 parts of sodium cocoyl isethionate, and adjusting the pH of a dyeing solution to be 5-6 by adopting acetic acid; S5, performing water washing again; S6, carrying out color fixing treatment, and S7, performing shaping to obtain the crystal linen fabric with high color fastness through the step S7. Ammonium sulfate serves as a corrosion inhibitor, so that the dyeingspeed of the disperse dye and spandex can be slowed down, the dyeing speed of the disperse dye and the polyester and the spandex is equivalent; and the sodium cocoyl isethionate can increase the acting force of the disperse dye and the spandex, so that the connection fastness between the disperse dye and the spandex is enhanced.

Description

technical field [0001] The invention relates to the technical field of textiles, more specifically, it relates to a dyeing process of crystal linen fabrics. Background technique [0002] Crystal linen is a kind of fabric, which consists of 92% polyester and 8% spandex. It is characterized by fine and smooth lines, excellent hand feeling, strong drapability, strong hemp feeling, and wrinkle resistance. Because crystal hemp has delicate texture, good drape, slight hemp feeling, and is not easy to wrinkle, it is suitable for high-end women's clothing fabrics in spring and autumn such as fashion, women's clothing, evening wear, etc. It is a high-grade and high-quality fabric; It is very comfortable to wear, loved by customers, and can be worn in all seasons. [0003] In order to be suitable for different occasions and different groups of people, crystal hemp needs to be dyed. The essence of crystal linen fabric is a polyester-spandex blended fabric with low spandex content. As...
