Embodiment 1

[0020] A process for preparing a highly moisture-absorbing, moisture-retaining, and stretch-resistant fabric using silk, comprising the steps of:

[0021] S1. 15 parts of silk were degummed and swelled sequentially in parts by weight, then 18 parts of monomethoxypolyethylene glycol and 75 parts of methylene chloride were added, mixed evenly, 3 parts of acetic acid were added and stirred evenly, and 2 parts of Jones reagent were added dropwise , adjust the temperature to 5°C and stir for 20 minutes, filter and wash to obtain silk fiber prefabricated material;

[0022] S2. After the silk fiber prefabricated material is dried, soak it in the moisturizing solution, let it stand for 3 hours, the standing temperature is 30°C, dry it, and then soak it in the silk fibroin aqueous solution, remove the excess solution on the surface after taking it out, ethanol water Steam setting, washing, drying, and interweaving to obtain high moisture absorption, moisture retention and stretch resis...

Embodiment 2

[0025] A process for preparing a highly moisture-absorbing, moisture-retaining, and stretch-resistant fabric using silk, comprising the steps of:

[0026] S1. 25 parts of silk were degummed and swelled sequentially by weight, then 10 parts of monomethoxypolyethylene glycol and 85 parts of methylene chloride were added and mixed evenly, 1 part of acetic acid was added and stirred evenly, and 4 parts of Jones reagent were added dropwise , adjust the temperature to 2°C and stir for 40 minutes, filter and wash to obtain silk fiber prefabricated material;

[0027] S2. After drying the silk fiber prefabricated material, soak it in the moisturizing solution, let it stand for 1 hour, and the standing temperature is 40°C; dry it, and then soak it in the silk fibroin aqueous solution, remove the excess solution on the surface after taking it out, and ethanol water Steam setting, washing, drying, and interweaving to obtain high moisture absorption, moisture retention and stretch resistan...

Embodiment 3

[0030] A process for preparing a highly moisture-absorbing, moisture-retaining, and stretch-resistant fabric using silk, comprising the steps of:

[0031] S1. 18 parts of silk were degummed and swelled sequentially by weight, then 16 parts of monomethoxypolyethylene glycol and 78 parts of methylene chloride were added and mixed evenly, 2.5 parts of acetic acid was added and stirred evenly, and 2.5 parts of Jones reagent was added dropwise , adjust the temperature to 4°C and stir for 25 minutes, filter and wash to obtain silk fiber prefabricated material;

[0032] S2. After drying the silk fiber prefabricated material, soak it in the moisturizing solution, let it stand for 2.5 hours, and the standing temperature is 32°C; dry it, then soak it in the silk fibroin aqueous solution, remove the excess solution on the surface after taking it out, and ethanol Steam setting, washing, drying, and interweaving to obtain high moisture absorption, moisture retention and stretch resistance ...

Abstract

The invention provides a technology for preparing stretch-proof fabric with high moisture absorption and moisturizing performance from silk. The technology comprises the steps as follows: silk is sequentially subjected to degumming and swelling treatment, methoxy polyethylene glycol and dichloromethane are added and uniformly mixed, acetic acid is added and uniformly mixed, a Jones reagent is dropwise added, temperature adjustment, stirring, filtration and washing are performed, and prefabricated silk fiber is obtained; the prefabricated silk fiber is aired, then dipped in a moisturizing solution, left to stand, dried, dipped in a silk fibroin aqueous solution and taken out, the extra solution on the surface is removed, ethanol steam setting, washing and drying are performed, and the stretch-proof fabric with high moisture absorption and moisturizing performance is obtained. The obtained silk fabric has excellent moisture absorption up to 39% or above, cannot break easily, has good toughness and excellent mechanical performance and has the breaking strength up to 576 Mpa and elongation at break up to 126% or above.

Description

technical field [0001] The invention relates to the technical field of silk textiles, in particular to a process for preparing high moisture-absorbing, moisturizing and stretch-resistant fabrics by using silk. Background technique [0002] With the gradual improvement of people's living standards, people have put forward higher requirements on the clothing fabric itself, not only to be durable and comfortable, but also to have antibacterial and antibacterial functions. As we all know, silk fabrics have always been famous for their skin-friendly comfort and certain health benefits, but the hygroscopicity of silk fabrics is not high, and the moisture regain is only 11%, which greatly limits the application of silk fabrics in the field of moisture absorption. In addition, the silk fiber is processed through processes such as degumming, which causes the silk fabric to break easily. Contents of the invention [0003] The purpose of the present invention is to provide a process...
