Abstract

The invention belongs to the technical field of novel spinning, and relates to a phenyl salicylate anti-ultraviolet blended yarn. The blended yarn comprises the following components in parts by weight: 40-75 parts of cotton fibers, 20-50 parts of polyurethane fibers and 5-10 parts of bamboo fibers. A production process of the blended yarn comprises the following steps that pre-treating and openingare carried out; the cotton fibers are impregnated in a phenyl salicylate ultraviolet absorber with the temperature of 50 DEG C for 3 hours, and then are taken out and aired to prepare cotton fiberswith the phenyl salicylate ultraviolet absorber on the surfaces; the prepared cotton fibers and the polyurethane fibers are subjected to a sandwich type lay-up mixing according to a blending ratio; anopening and cleaning process is carried out, wherein the cotton fibers and the polyurethane fibers after lay-up mixing sequentially pass through a bale plucker, a cotton blending machine and a rolling machine to complete an opener process; a cotton carding process, a drawing process, a roving process and a spun yarn process are carried out to prepare roving; the bamboo fibers and the roving are blended to prepare the yarn. The prepared yarn has the relatively good anti-ultraviolet performance, has no irritation and anaphylactic reaction on the skin, is washable and has the high elasticity.
