Multifunctional modification treatment method for silk

Abstract

The invention discloses a method for multifunctional modification of silk, which comprises: dipping and rolling silk twice in a finishing liquid containing chitosan guanidine hydrochloride, polycarboxylic acid and sodium hypophosphite, and the excess ratio is 80~120%, microwave irradiation for 1~5min, power 300~700W, fully wash with hot water at 50℃, wash with cold water, and finally dry. The invention has simple process, saves energy, reduces or prevents environmental pollution, and is suitable for industrialized production; the silk fabric modified by the invention not only has good wrinkle resistance and antibacterial properties, but also can greatly improve the active dyes used in silk after treatment. Dyeing performance of silk fabrics with acid dyes.

Description

Technical field: [0001] The invention belongs to the field of silk modification treatment, in particular to a multifunctional modification treatment method of silk. Background technique: [0002] As we all know, silk has long been well-known in the market for its smooth feel, soft luster, excellent moisture absorption and comfort, and has the reputation of "fiber queen". China is the birthplace of silk. Silk weaving is a major contribution of ancient my country to the material and spiritual civilization of the world. Although silk has a long cultural history and is loved by people, there is no strong chemical cross-linking between the molecules of silk, and the salt bonds, hydrogen bonds and van der Waals forces of protein macromolecules are easily destroyed, which determines its easy occurrence. wrinkled properties. [0003] At present, the modification methods of silk mainly include physical modification, chemical modification and blending modification with nanoparticles,...

AI Technical Summary

Problems solved by technology

For example, the traditional chemical modification of silk is mostly carried out by heat conduction heating. This method of heating often has problems such as uneven heating and long heating time.
