Problems solved by technology

[0003] Silk is a natural protein fiber with unique styles such as moisture absorption, breathability, softness and smoothness, and soft luster. According to research reports, silk fabrics are treated with organic phosphorus flame retardants, and the flame-retardant silk fabrics obtained have high residual free formaldehyde content. , and the strength of silk fabric also decreased

Abstract

The invention discloses a preparation method of a flame-retardant photochromic silk fabric. The method comprises the following steps: (1) preparing a padding liquid: ultrasonically and uniformly stirring photochromic powder, a flame retardant, a softening agent, a crosslinking agent, catalyst and deionized water to obtain the padding solution; (2) soaking the silk fabric in the padding solution, padding twice and rolling twice, wherein the pick-up rate is 80-90%; (3) taking out the silk fabric, washing for 2-3 times by using hot water, washing for 2-3 times by using cold water, drying for 5-10 min at 50-80 DEG.C, baking for 2-5 min at 120-150 DEG.C to obtain the flame retardant photochromic silk fabric. The flame-retardant photochromic silk fabric prepared by the invention is soft and comfortable, the limiting oxygen index reaches up to 40% or above, the free formaldehyde is less, and the environment is protected.

Description

Technical field: [0001] The invention relates to the technical field of silk, in particular to a method for preparing a flame-retardant photochromic silk fabric. Background technique: [0002] In recent years, fires have occurred frequently in our country, which has caused a great threat to the safety of human life and property. The textile industry and interior decorations have the highest frequency of fires. Similarly, the harmful gas released by combustible textiles is far greater than that of flame-retardant textiles. And along with the raising of people's living standard, people can not only consider the comfort of fabric when choosing fabric, also can consider the fashion and functionalization of fabric etc. Therefore, multifunctional silk textiles have become a research hotspot. [0003] Silk is a natural protein fiber with unique styles such as moisture absorption, breathability, softness, smoothness, and soft luster. According to research reports, silk fabrics are...
