Abstract

The invention discloses a modification method of anti-ultraviolet aging polyester fiber. The method is characterized in that spherical TiO2 nanoparticles are firstly prepared, a porous carbon shell layer is prepared on the surfaces of the particles, TiO2@C nanoparticles with core-shell structures are prepared, then the nanoparticles are used as main ingredients to prepare a finishing agent, an impregnation method is utilized to support the nanoparticles on polyester fiber, and modified polyester fiber is obtained. After the modified polyester fiber is dried, the anti-ultraviolet aging polyester fiber is obtained. The modification method is simple, the anti-ultraviolet aging capability of the polyester fiber can be improved, the mechanical strength of the polyester fiber can be also better kept, and the modification method has an important application significance.

Description

technical field [0001] The invention relates to an anti-ultraviolet aging modification method of polyester fibers, which belongs to the technical field of functional fibers and textile engineering. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. Its synthesis process is simple, the price is cheap, and it is not easily deformed, insulated, crisp, easy to wash and quick-drying, so it is loved by people and is currently widely used in clothing, footwear, bedding and other fields. In addition, due to its excellent physical and mechanical properties, high chemical stability, and good weather resistance, polyester fibers are also used as cords for tire casings and binding yarns in glass fiber composite mats. [0003] Although the chemical stability of polyester fiber is good, but with the development of industry, the degree of environmental pollution increases, resulting in the destructio...
