Embodiment 1

[0021] A kind of silk fabric anti-wrinkle finishing process, described process comprises the following steps:

[0022] (1) The real silk fabric is mixed with a mass concentration of 10g / L sodium sulfite aqueous solution, and reacted for 2 hours under normal temperature conditions. After the reaction is completed, it is repeatedly washed with deionized water and dried naturally;

[0023] (2) Soak the silk fabric treated in step (1) in phosphate buffer for 24 hours, take it out and dry it at a constant temperature of 55°C;

[0024] (3) Add water-soluble polyurethane, chitosan and deionized water to the Erlenmeyer flask, and add hydrochloric acid dropwise to make the pH value of the solution 1.5, place it in a water bath at 30°C, and shake vigorously for 12 minutes;

[0025] (4) Add softener, strong protective agent, catalyst and penetrating agent to the system in step (3), and stir and mix evenly under the condition of 40° C. to prepare anti-wrinkle finishing solution;

Abstract

The invention discloses an anti-wrinkle finishing process for a natural silk fabric. The process comprises the steps of pretreatment of the natural silk fabric, preparation of an anti-wrinkle finishing solution, anti-wrinkle finishing and the like. The natural silk fabric obtained by finishing in the process disclosed by the invention has the advantages of good wrinkle recovering property, strength retention rate as well as excellent hydrophilcity and hand feeling; wear resistance of the natural silk fabric obtained by finishing in the process is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a preparation method of functional fabrics, in particular to an anti-wrinkle finishing process of real silk fabrics. Background technique [0002] Since there is no chemical crosslinking between the protein macromolecules of real silk, when the silk fiber absorbs water and swells, the salt bond breaks. When the silk fabric is wet, the molecular chain is easy to slip relative to each other, and when the external force is removed, there is not enough binding force between the molecules to make it return to its original position, which makes the wet wrinkle resistance of the silk fabric very poor, which greatly affects the practical effect of the fabric. This is a serious shortcoming of real silk fabrics, which brings a lot of inconvenience to the use of silk, so it is necessary to carry out anti-wrinkle finishing on real silk fabrics. [0003] In the prior art, the composition of o...
