Problems solved by technology

[0003] Due to the excellent hygroscopic properties of vinylon fiber, it is often used to make summer clothes. However, the summer weather is hot and the intensity of ultraviolet rays is high, so sun protection has become an important thing. Due to the characteristics of vinylon fiber, its sunscreen and anti-ultraviolet properties The ability is poor, so it needs to be modified for sun protection and UV protection. At the same time, the temperature in summer is suitable, and bacteria and other microorganisms are easy to breed on the surface of clothing. For the physical and mental health of consumers, the antibacterial performance of clothing has become extremely important.

Abstract

The invention belongs to the technical field of production of textile fibers and discloses a sun-proof and antibacterial fiber protofilament. The sun-proof and antibacterial fiber protofilament is produced from the raw materials such as polyvinyl alcohol, a sun-proof additive, an antibacterial additive and water and the like, wherein the sun-proof additive comprises fibrous titanium dioxide, glucose and sodium ascorbate; the antibacterial additive comprises aluminum phosphate, calcium phosphate and aluminum tripolyphosphate. The sun-proof antibacterial fiber protofilament based on polyvinyl acetal fiber is high in strength, high in tenacity and excellent in moisture absorption property and has sun-proof, ultraviolet-proof and antibacterial functions; the sun-proof property of the fiber protofilament meets the national standard; the antibacterial property of the fiber protofilament is excellent.

Description

technical field [0001] The invention relates to the technical field of textile fiber manufacturing, in particular to a sunscreen and antibacterial fiber precursor. Background technique [0002] Polyvinyl acetal fiber, also known as vinylon fiber, has a relative density of 1.26-1.30g / cc, a softening point of 220-230°C, and a softening point of 110°C in water; the fineness of cotton-type short fibers is 1.4 denier; the dry and wet strengths are 5.4 gram force / denier, 4.3 gram force / denier, dry and wet elongation are 16.5%, 17.5% respectively, Young's modulus 550 kg force / mm, elastic recovery rate (3%) 70%; it is characterized by high strength, toughness Good moisture absorption, wear resistance, acid and alkali resistance, high wet strength, not afraid of mould, etc. Vinylon fiber is mainly used to make clothes, and can also be used to make various cables, canvas, agricultural windproof, cold-proof gauze, etc. [0003] Due to the excellent hygroscopic properties of vinylon fi...
