Abstract

The invention provides silk with high light resistance and a preparation method thereof, and specifically relates to the technical field of silk processing. The invention improves the light resistance of silk from the source of silk preparation. Firstly, after cocoon cooking, a protective agent is added for soaking, then a penetration aid is added to reel silk, and then a protective film is formed on the surface of silk by radiation polymerization, so that the silk can be exposed to ultraviolet light. Under the conditions of the light-accelerated destruction test, it maintains good color, toughness and mechanical strength, so that the change in breaking strength is less than 5cN, the elongation at break is reduced within 5%, and the whiteness reduction rate is within 5%.

Description

【Technical field】 [0001] The invention relates to the technical field of silk processing, in particular to a silk with high light resistance and a preparation method thereof. 【Background technique】 [0002] Silk is a continuous long fiber formed by solidification of the silk liquid secreted by cooked silkworms when cocooning. It is also called natural silk. It is a natural protein fiber material and one of the earliest animal fibers used by humans. one of the main raw materials. Silk is a product of ancient Chinese civilization. According to legend, the concubine of the Yellow Emperor, Luo Zu, first taught the people to raise silkworms. According to archaeological findings, about 4,700 years ago, China had used silk to make silk threads, woven ribbons and simple silk fabrics. By the Shang and Zhou dynasties, silk weaving such as Luo, damask, Wan, yarn, crepe, Qi, brocade and embroidery had appeared. And other silk fabrics. [0003] Silk not only has good hygroscopicity, m...
