Problems solved by technology

Li Yongqiang et al. (Research on D4 plasma surface modification of mulberry silk fiber, Journal of Textile Science, 2006, 6th issue) used D4 (octamethylcyclotetrasiloxane) low-temperature plasma to irradiate silk fiber, and the surface properties of silk were greatly improved. The silk fabric modified by plasma has higher interweaving resistance, wrinkle resistance and softness have also been significantly improved, and good water repellency effect has been obtained, but due to the limitations of equipment and conditions, it is not yet possible Industrial application

Abstract

The invention discloses soft lubricous grafting-modified silk and a preparation method thereof and a grease emulsion. Epoxidized soybean oil or epoxidized soybean oil fatty acid methyl ester is grafted to a silk fiber; a long-chain oleophilic compound is grafted to the surface of macromolecules of the silk fiber; the silk fiber is soft and smooth to touch. Since the graft material is a natural biomass material which is biodegradable and environmentally friendly, a functional finishing method of the ecological silk fiber herein is green.

Description

technical field [0001] The invention relates to soft and lubricating grafted modified silk and a preparation method thereof, and also relates to an oil emulsion used for soft and lubricated grafted modification of silk, which belongs to the technical field of silk modification. Background technique [0002] Silk is an animal protein material, mainly composed of sericin and silk fibroin, of which silk fibroin accounts for about 3 / 4, and sericin accounts for about 1 / 4. Sericin and silk fibroin are composed of 18 kinds of amino acids and contain about 97% pure protein. The fiber processed and finished by silk is a kind of high-grade fabric raw material. The chemical and physical properties of the fiber material directly affect the comfort and feel of the fabric. Exploring the methods of soft finishing and improving the feel of silk fabrics has become an increasing silk product. It is an effective way to develop high-grade functional silk fabrics. The softener of chemical mate...
