Problems solved by technology

[0003] However, the shrinkage rate of silk and linen fabrics is generally high, which seriously affects the performance and dimensional stability of the fabrics.
At home and abroad, there are few studies on the anti-shrinkage technology of silk and linen fabrics, and the existing anti-shrinkage technology still cannot meet the relevant standards. It has become an important problem to be solved urgently for silk and linen fabrics

Embodiment 1

[0035] Such as figure 1 Shown is the padding tank that needs to be used in chemical finishing. The unimpregnated fabric 1 first passes through the impregnation tank 2 filled with impregnation liquid, and is impregnated for 30 minutes under the action of the impregnation roller 3, and then the impregnated fabric is introduced into the pressure roller 5 through the cloth guide roller 4, and the excess finishing liquid in the fabric is impregnated. The fabric that is rolled out by the roller is the fabric that is padded, and finally the padding process is repeated.

[0036] Concrete preparation process is as follows:

[0037] (1) Physical shrinkage

[0038] Soak the silk and linen fabric in a constant temperature water bath at 65°C for 60 minutes, then move it into an electric blast oven, and dry it at 65°C for 5 minutes to obtain a preshrunk silk and linen fabric;

[0039] (2) chemical finishing

[0040] ① Preparation of finishing solution: finishing solution includes ci...

Embodiment 2

[0062] use figure 1 The padding tank shown. Concrete preparation process is as follows:

[0063](1) Physical shrinkage

[0064] Soak the silk and linen fabric in a constant temperature water bath at 30°C for 90 minutes, then move it into an electric blast oven, and dry it at 95°C for 25 minutes to obtain a preshrunk silk and linen fabric;

[0065] (2) chemical finishing

[0066] ① Preparation of finishing solution: finishing solution includes citric acid, polymaleic acid, sodium hypophosphite, triethanolamine, boric acid, fatty alcohol polyoxyethylene ether;

[0067] The composition of described finishing solution is:

[0068] Citric acid 40g / L

[0069] Polymaleic acid 20g / L

[0070] Sodium hypophosphite 40g / L

[0071] Triethanolamine 20g / L

[0072] Boric acid 4g / L

[0073] Fatty alcohol polyoxyethylene ether 3g / L

[0074] Weigh the above amount of chemical finishing agent, and then add deionized water to prepare 1000mL finishing s...

Embodiment 3

[0088] use figure 1 The padding tank shown. Concrete preparation process is as follows:

[0089] (1) Physical shrinkage

[0090] Soak the silk and linen fabric in a constant temperature water bath at 80°C for 120 minutes, then move it into an electric blast oven, and dry it at 80°C for 10 minutes to obtain a preshrunk silk and linen fabric;

[0091] (2) chemical finishing

[0092] ① Preparation of finishing solution: finishing solution includes citric acid, polymaleic acid, sodium hypophosphite, triethanolamine, boric acid, fatty alcohol polyoxyethylene ether;

[0093] The composition of described finishing solution is:

[0094] Citric acid 50g / L

[0095] Polymaleic acid 16.67g / L

[0096] Sodium hypophosphite 50g / L

[0097] Triethanolamine 25g / L

[0098] Boric acid 6g / L

[0099] Fatty alcohol polyoxyethylene ether 4g / L

[0100] Weigh the above amount of chemical finishing agent, and then add deionized water to prepare 1000mL fi...

Abstract

The invention discloses a preparation method of an anti-shrink silk-linen fabric, and belongs to the technical field of textile post treatment. In the provided preparation method, a physical pre-shrinking and chemical finishing combined method is adopted to carry out a post treatment on silk-linen fabrics. The post-treatment method comprises a physical technology and a chemical technology, the used finishing agent is an environment-friendly flame retardant, and the whole finishing process is easy and simple. After the treatment, the warp-direction shrinkage rate is reduced from 6.8% to 0.7% or less; the weft-direction shrinkage rate is reduced from 2.5% to 0.7% or less, the textile drape coefficient is 0.58 U or less, warp-direction wrinkle recovery angle is 130 to 150 degrees, the weft-direction wrinkle recovery angle is 74.6 to 85 degrees, the textile weight gain rate is 2.5 to 3.6%; the application performance of the silk-linen fabrics is enhanced, and the provided method is an ideal method for silk-linen fabric anti-shrink treatment.

Description

technical field [0001] The invention relates to a method for preparing an anti-shrinkage silk hemp fabric, which belongs to the technical field of textile finishing. Background technique [0002] With the improvement of living standards, people's requirements for clothing fabrics tend to be more comfortable, light and thin, and high-end. As a newly developed high-grade interwoven fabric, silk-linen fabric has both the smoothness and softness of silk and the coolness and crispness of hemp. It has the advantages of good moisture absorption and moisture conductivity, and good antibacterial properties. It is a very popular textile fabric. But also has a high added value. [0003] However, the shrinkage rate of silk and linen fabrics is generally high, which has a strong impact on the performance and dimensional stability of the fabrics. At home and abroad, there are few studies on the anti-shrinkage technology of silk and linen fabrics, and the existing anti-shrinkage technolo...
