Problems solved by technology

[0003] At present, there is no cashmere product with flame retardant and anti-ultraviolet radiation in China. The research on flame retardant of textiles has made some progress, especially the research on flame retardant systems containing halogen, phosphorus and titanium elements, some of which have been applied, but these retardant The combustion system contains toxic and harmful substances and urgently needs to be improved; similarly, textile UV absorbers such as benzophenones, p-aminobenzoic acids, and salicylates have poor heat resistance, short service life, great skin irritation, and poor washing resistance. And other shortcomings, also need to improve and break through

Abstract

The invention provides a method for preparing flame retardant anti-UV radiation cashmere fiber product, belongs to the technical field of textile. The method includes the main steps of firstly washing pure cashmere fibers and drying, secondly preparing a silicon alumina oxide sol impregnation solution, wherein the silicon alumina oxide sol is an environmental-friendly flame retardant, then impregnating the pure cashmere fibers with the silicon alumina oxide sol, performing flame retardant treatment for the pure cashmere fibers, then preparing a TiO2-ZnO hydrosol which is also an environmental-friendly chemical reagent, finally impregnating and roll-drying the pure cashmere fibers with the TiO2-ZnO hydrosol repeatedly, performing anti-UV radiation treatment on pure cashmere fibers, and then washing and drying the pure cashmere fibers to get the flame retardant anti-UV radiation cashmere with high performance. Compared with the prior art, cashmere fibers processed by the method have good flame retardant anti-UV radiation function, and the added value of cashmere is further improved. Treated by the sol-gel technique, breaking strength and shrinkproof performance of the cashmere fabric are improved to some extent.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing cashmere fibers which are flame-retardant and ultraviolet-resistant. Background technique [0002] Cashmere is a thin layer of fine wool that grows in the outer cortex of goats and at the root of the goat's coarse hair. Cashmere is much thinner than wool, and the outer scales are also finer and smoother than wool. Therefore, it is light in weight, soft and tough. It is especially suitable for making underwear. When worn next to the skin, it is light, soft, soft and smooth, and very comfortable. It is incomparable to any fiber. It is called "soft gold" among fibers. Cashmere is a natural protein fiber, containing more cystine, glutamic acid, arginine, etc., and a cross-linked polypeptide with a folded molecular structure. Natural cashmere has high flame resistance, but cashmere fabrics are processed with a lot of additives, which makes them ea...
