Problems solved by technology

However, the combination of chemical bonds between the added UV-shielding agent and the woven fabric cannot occur, and the washing fastness is poor. Therefore, after washing the fabric several times, the UV-shielding agent will be washed off, so that the fabric loses its anti-ultraviolet properties. ability

Abstract

The invention relates to a DTY yarn containing an anti-ultraviolet agent and a production process thereof, belonging to the technical field of textiles. The production process of the DTY yarn comprises the following steps: S1: melt-blending and extruding the mixed fibers at a temperature of 260-290° C. out, to obtain the mixed pellets; S2: pre-crystallize the compound pellets at a temperature of 160-164 °C for 10-20 min, and then dry at a temperature of 160-170 °C to obtain dry mixed pellets; S3: dry the pellets The mixed pellets and the dried anti-ultraviolet agent are put into the screw extruder, melt-blended and extruded, and then put into the spinning machine, and the spinning process is carried out to obtain POY yarn; S4: POY yarn is passed through the first Roller, hot box deformation, false twister twisting, second roller, network nozzle, hot box setting, third roller, oiling, winding, to obtain DTY yarn with anti-ultraviolet agent, the DTY yarn prepared by the present invention has The effect of long-lasting UV resistance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a DTY yarn containing an anti-ultraviolet agent and a production process thereof. Background technique [0002] DTY yarn, also known as stretch textured yarn, usually uses POY yarn as raw yarn, which is continuously or simultaneously stretched on a texturing machine, and then a finished yarn after being deformed by a twister. Textile, processed into fabrics. [0003] In recent years, with the destruction of the natural environment, the ozone layer has gradually become thinner. For every 1% decrease in the ozone layer, the radiation intensity of ultraviolet rays will increase by 2%. Excessive ultraviolet rays are irradiated on the human body, which is prone to accelerated wrinkles and skin aging. , and even burns, skin cancer and other lesions. Therefore, the research on anti-ultraviolet fabrics has gradually developed. [0004] The existing anti-ultraviolet fabrics are usuall...
