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 an anti-ultraviolet DTY yarn and a production process thereof, belonging to the technical field of textiles. The raw materials used for the anti-ultraviolet DTY yarn comprise the following components in parts by weight: 15-25 parts of uran grass fiber, 18-22 parts of coconut charcoal fiber, corn 20-25 parts of fiber, 30-40 parts of polylactic acid fiber, and 35-45 parts of polypropylene fiber, the anti-ultraviolet DTY yarn of the present invention has the effect of long-term anti-ultraviolet ability.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an anti-ultraviolet DTY yarn 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 usually made by first spi...
