Abstract

The invention discloses a finishing technology for the yellowing prevention silk fabric, and belongs to the technical field of silk. The finishing technology comprises the following steps: dissolving waste silk by using a lithium bromide solution to prepare a silk fibroin solution; immersing silk fabric into the silk fibroin solution containing ethylene glycol diglycidyl ether, taking out the silk fabric, naturally curing, and then immersing the silk fabric into a titanium dioxide sol solution; performing heat treatment after twice immersing and twice rolling; washing and drying to obtain the silk fabric subjected to yellowing-prevention finishing. The finishing method is simple and convenient to operate, can protect silky luster of the silk fabric, and has outstanding advantages in anti-aging and yellowing prevention; the waste silk is used as a raw material, so that the finishing method is environment-friendly and conducive to resource regeneration; the silk fabric prepared by the finishing method is comfortable, safe, environment-friendly, healthy and fashionable.

Description

Technical field: [0001] The invention relates to the technical field of silk, in particular to an anti-yellowing finishing process of silk fabrics. Background technique: [0002] Sunlight contains a large amount of ultraviolet rays, most of which will be absorbed by the ozone layer in the air, and only about 10% of the ultraviolet rays will be projected onto the ground. A moderate amount of ultraviolet radiation is necessary for the growth of human body and plants, but excessive exposure to ultraviolet radiation can cause many problems. [0003] Silk is a kind of natural protein fiber, which mainly contains silk fibroin, sericin and a small amount of other substances. Under the action of light, heat, biology and other factors, silk fiber will turn yellow. Its mechanical properties, surface morphology, aggregate structure, molecular The quality and so on have all changed, and the light has a greater effect on the yellowing process of silk fabrics. [0004] Usually, refined ...
