Abstract

The invention discloses a functional synthetic fiber capable of removing formaldehyde and preparation and application of the fiber. Rod-like zinc oxide is adopted as a vector, loaded with a halogen bismuth oxide, and then added to a synthetic fiber by adopting a fusing method, so as to obtain the functional synthetic fiber capable of removing the formaldehyde. The functional synthetic fiber has the advantages and effects that (1) the rod-like zinc oxide is adopted as the vector, so that the agglomeration of the halogen bismuth oxide can be prevented, and the catalyst activity is obviously improved; (2) the rod-like zinc oxide is taken as the vector, loaded with a halogen bismuth oxide visible-light-driven photocatalyst, and then fused and added to the synthetic fiber, so that the problems of recovery and reutilization of the visible-light-driven photocatalyst can be solved, the functional synthetic fiber has the reusability, the secondary pollution can be avoided, and the cost is reduced; (3) the obtained functional synthetic fiber has the visible-light catalytic activity, and can play a role of removing the formaldehyde under irradiation of visible light, so as to prepare curtains, clothes, textiles and the like with the effect of removing the formaldehyde. Thus, the application range of the synthetic fiber is further expanded.

Description

technical field [0001] The invention belongs to the field of synthetic fiber materials and relates to a functional synthetic fiber capable of removing formaldehyde and its preparation and application, in particular to a functional synthetic fiber containing rod-shaped zinc oxide / bismuth oxyhalide and its preparation and application. Background technique [0002] Synthetic fiber is a chemical fiber made from artificially synthesized linear polymers with suitable molecular weight and solubility (or meltability) through spinning and post-processing. It mainly includes carbon chain synthetic fibers, such as polypropylene fiber (polypropylene fiber), polyacrylonitrile fiber (acrylic fiber), polyvinyl formal fiber (vinylon); and hybrid chain synthetic fiber, such as polyamide fiber (nylon), polyparaffin Ethylene phthalate (polyester), etc. In order to broaden its application range, high temperature resistant fibers, high temperature corrosion resistant fibers, high strength fiber...
