Abstract

The invention provides a method for preparing amorphous and nanocrystalline improved polyester self-cleaning shielding fibers, which mainly includes selecting polyester chips with good spinnability as spinning substrates, and selecting amorphous and nanocrystalline nano functional powders as functional additives, wherein the functional The additives are selected from CNTs (mass fraction 0.05%~8%) that can improve electrical conductivity and mechanical properties, one or all of magnetic nanoparticles FeCo, Fe3O4 (0.05%~12%), spinning matrix and functional Additive blending, melt spinning and other processes. The fiber obtained by the invention can achieve the uniform dispersion and spinnability of the nano-additive, and at the same time has the synergistic effect of improving the mechanical properties, increasing the antibacterial properties and electromagnetic shielding properties of the polyester polyester.

Description

technical field

[0001] The invention relates to a method for preparing amorphous and nanocrystalline modified polyester. The fiber obtained by the method has the functions of self-cleaning and electromagnetic shielding. Background technique

[0002] With the development of modern high-tech and the use of various household appliances, electronic equipment, office automation equipment, radar, television broadcasting and other electrical devices, electromagnetic radiation has become an invisible public hazard. Electromagnetic interference not only interferes with electrical equipment, but also poses a serious threat to human health. From the 1990s to the present, countries all over the world are scrambling to study new electromagnetic shielding materials, especially the development and development of electromagnetic shielding fibers, and have made some progress.

[0003] The first generation of shielding fiber is made of metal fiber, which is blended (knitted) with metal wire ...
