Problems solved by technology

[0005] The common production method of functional fibers is the physical modification method, that is, blending and adding anti-ultraviolet functional substances at different stages of fiber molding, but the disadvantage of this method is that it is difficult to achieve good dispersion of anti-ultraviolet substances in polyester resin. Uneven powder materials will increase the spinning pressure during spinning, block the spinneret, and affect the spinnability of the fiber, and the uneven dispersion of the anti-ultraviolet agent will further affect the anti-ultraviolet performance of the fiber
For example, the Chinese invention whose publication number is CN1357650 discloses a kind of nylon-6 anti-ultraviolet fiber, which adopts the additive-SiO 2 -x ,TiO 2 , ZnO, etc. The disadvantage of this method is that the biggest problem when using nano-scale ultraviolet shielding additives is that they are easy to agglomerate and cannot be uniformly dispersed in the matrix, which will directly increase the difficulty of spinning and cause the decline or loss of anti-ultraviolet performance.

Abstract

The invention belongs to the field of textiles, and in particular relates to anti-ultraviolet polyester fibers. The anti-ultraviolet polyester fibers are prepared by melt-spinning the following materials in parts by weight: 100 parts of PET chips and 1-5 parts of anti-ultraviolet polyester master batches, wherein the anti-ultraviolet polyester master batches are prepared by melt-blending and extruding the PET chips, and 2-5% of pre-treated nano-ceramic powder, 1-3% of an anti-oxidant, 0.5-2% of a lubricating agent and 0.4-3% of a dispersant based on the weight of the PET chips; and the pre-treated nano-ceramic powder is obtained by coating the nano-ceramic powder with a hydroxypropyl-beta-cyclodextrin solution. According to the anti-ultraviolet polyester fibers and the preparation method thereof, the problem about uniform distribution of small-particle nano-ceramic powder in a PET substrate is solved; high-efficiency and long-lasting anti-ultraviolet polyester fibers are prepared by melt-spinning; and the method disclosed by the invention is simple and feasible, and is applicable to industrial popularization and use.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to an anti-ultraviolet polyester fiber and a preparation method thereof. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has certain special functions in addition to the physical and mechanical properties of ordinary fibers. With the improvement of people's living standards, the demand for functional fibers is increasing, and UV-resistant functional fibers are an important category. [0003] Generally speaking, appropriate ultraviolet rays are beneficial to the...
