N-butyl salicylate anti-ultraviolet blended yarn and production process thereof

Abstract

The invention belongs to the technical field of novel spinning, and relates to an n-butyl salicylate anti-ultraviolet blended yarn. The n-butyl salicylate anti-ultraviolet blended yarn comprises, by weight, 40-80 parts of cotton fiber, 10-30 parts of spandex fiber and 10-30 parts of bamboo fiber. The production process of the n-butyl salicylate anti-ultraviolet blended yarn comprises the followingsteps of pretreating and opening; dipping the cotton fiber into an n-butyl salicylate ultraviolet absorbent for 3 hours, taking out and airing to prepare the cotton fiber with the n-butyl salicylateultraviolet absorbent on the surface; performing "sandwich" type layering mixing on the prepared cotton fiber and the spandex fiber according to a blending ratio; performing an opening and picking process: sequentially enabling the cotton fiber and the spandex fiber after layering mixing to pass through a bale plucker, a cotton blending machine and a lap machine to complete a cotton opener process; performing a cotton carding process, a drawing process, a roving process and a spinning process to prepare roving; and blending the bamboo fiber and the roving to prepare the yarn. The prepared yarnhas good anti-ultraviolet performance, washing resistance and good elasticity.

Description

technical field [0001] The invention belongs to the technical field of novel spinning, and in particular relates to n-butyl salicylate anti-ultraviolet blended yarn and a production process thereof. Background technique [0002] With the development of living standards, for textile fabrics, people are no longer only satisfied with clothing, people are more looking for functional fabrics to meet functional requirements. Preventing ultraviolet rays from harming the human body has been valued by more and more consumers. Ultraviolet rays in the solar spectrum not only make textiles fade and embrittle, but also cause sunburn and aging of human skin, resulting in melanin and stains, and more seriously, it can induce cancer and endanger human health. Anti-UV fabric is a material that protects the human body from excessive ultraviolet radiation. Yet the elasticity and warmth retention property of the cotton fiber blended yarn on the market are not good at present, therefore, there...
