Abstract

The invention provides an anti-ultraviolet polyester fiber composite finishing method which comprises the steps of firstly adding polymer powder and tetrabutylammonium hexafluorophosphate into a mixedsolvent of N, N-dimethylformamide and acetone, and completely dissolving to prepare a spinning mixed solution with the mass fraction ranging from 14 to 20 percent, wherein a polymer is polyacrylonitrile, nylon 6, polyether sulfone or thermoplastic elastomer polyurethane; carrying out high voltage electrostatic spinning on the obtained spinning mixed solution, and obtaining a nanometer polyester fiber membrane; then mixing soluble ferric iron salt, ethyl alcohol and water, and obtaining a ferrite complex solution; and under a protective atmosphere and a vibration condition, soaking the nanometer fiber membrane into the ferrite complex solution, adding NaBH4 for carrying out reduction reaction, and obtaining a nanofiber membrane loaded nanoscale zero-valent iron composite material. According to a textile fabric or braided fabric prepared by anti-ultraviolet polyester fibers provided by the invention, an ultraviolet protection factor (UPF) value is 30+, an arithmetic mean value T (UVA) AV of transmittance of an ultraviolet A (UVA) section is smaller than 5 and meets the national standards, and the average ultraviolet shield rate is more than 85 percent.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, in particular to a method for composite finishing of ultraviolet-resistant polyester fibers. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for clothing are not only beautiful and durable, but more and more focus on comfort. At the same time, people have higher and higher requirements for the health, safety and environmental protection of clothing fabrics. With the increase of people's outdoor activities, the trend of mutual penetration and integration of casual wear and sportswear has become increasingly popular among consumers. The fabrics of this type of clothing not only require good comfort, but also require less damage to people's bodies when they are active. Therefore, anti-ultraviolet requirements are put forward for the fibers of the fabric. [0003] Generally speaking, the selection of anti-ultraviolet agent ...
