Embodiment 1

[0092] The present embodiment provides a method for mercerizing, comprising the following steps:

[0093] Step 1, testing the alkali resistance of each dye in a plurality of fabrics to be mercerized.

[0094] Specifically include the following steps:

[0095] The textile fabric 100 dyed with the dye to be tested is sewn between the cotton cloth 200 and the fiber cloth to obtain a test piece 10 , and the test piece 10 is weighed.

[0096] Soak the test piece 10 in the lye (sodium hydroxide solution), the pH of the lye is 13, the temperature of the lye is 30°C, the soaking time is 1min to 3min, the quality of the lye and the test piece 10 The ratio is 45:1.

[0097] Take out the test piece 10 soaked in alkaline solution, squeeze out the liquid, and shake the test piece 10 in the washing liquid at a temperature of 70°C for 1 min. The mass ratio of the washing liquid to the test piece 10 is 45:1.

[0098] The test piece 10 was taken out, and after the liquid was squeezed out, t...

Embodiment 2

[0110] Dye preparation, the fabric dyed with a single dye will be tested for the alkali resistance performance of the dye and scored. Select dyes of four grades in yellow, red and blue after scoring, as shown in Table 1 below.

[0111] Table 1 Alkali resistance performance score of dyes

[0112] dye name Alkali Resistance Score of Dye Yellow Yellow 1 0.7 Yellow Yellow 2 1 Yellow Yellow 3 1.46 Yellow Yellow 4 1.94 Red Red 1 0.86 Red Red 2 1.24 Red Red 3 2 Red Red 4 2.36 Blue Blue 1 0.2 Blue Blue 2 1.36 Blue Blue 3 1.96 Blue Blue 4 2.72

[0113] Fabric preparation, use the dyes in the above table 1 to dye the yarn, and then weave the fabric with the dyed yarn, and weave into light, medium and dark solid color cloth and plaid cloth. At the same time, the length of these six fabrics with different patterns is 1,000 yards, and the specification is plain weave 40s*40s / 130*80. The relevant informat...

Abstract

The invention relates to a mercerizing method. The mercerizing method comprises the following steps: testing the alkali resistance of each dye in a plurality of fabrics to be mercerized; according to the alkali resistance and dosage ratio of the dye in each to-be-mercerized fabric, judging the easy-to-drop staining degree of each to-be-mercerized fabric; and sequentially mercerizing the plurality of fabrics to be mercerized according to the easy-to-drop staining degree from low to high. According to the mercerizing method, the multiple to-be-mercerized fabrics are sequentially mercerized according to the easy-to-drop staining degree from low to high by judging the easy-to-drop staining degree of each to-be-mercerized fabric, and the fabrics which are mercerized firstly are not easy to drop staining, that is, the degree of hydrolysis decoloring in the mercerizing process is low, and the degree of hydrolysis decoloring in the mercerizing process is low. Compared with the prior art, the color change degree of the treatment liquid is low, and the influence on the subsequent to-be-mercerized fabric is small, so that the water changing frequency can be reduced, the water consumption is reduced, the steam energy consumed by heating the treatment liquid is also saved, meanwhile, the equipment starting rate is increased, and the production efficiency is also correspondingly improved.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a mercerizing treatment method. Background technique [0002] Yarn-dyed fabrics are fabrics woven from dyed yarns. Among textile fabrics, yarn-dyed fabrics have the characteristics of bright colors and various patterns. With the change of weaving method, they have richer visual effects than other types of fabrics. Due to its complex processing technology and high production cost, yarn-dyed fabrics are generally only used to manufacture high-end fabric products. [0003] After the yarn-dyed fabric is woven, it generally needs post-processing such as desizing and mercerizing. Among them, for the mercerizing process, the reactive dyes commonly used in pure cotton fabrics have poor tolerance, and will be hydrolyzed and decolorized in large quantities during the mercerizing process. As the mercerizing process progresses, the color of the washing liquid gradually becomes d...
