Abstract

The invention relates to a preparation method of an antibacterial conductive polypropylene fiber yarn, and relates to the technical field of yarn production. According to the preparation method, a melt electrostatic spinning device serves as a generating device, the melt electrostatic spinning device comprises a melt spinning machine, an air spraying device and an electrostatic spinning machine, the air spraying device is arranged on the melt spinning machine, and the polypropylene fiber yarn prepared through melt spinning has certain thermal viscosity; the semi-molten polypropylene yarn can be directly combined with functional particles or functional powder. According to the polypropylene fiber yarn prepared through melt spinning, only polypropylene particles need to be fused and drawn into filaments at high temperature, compared with solution dry spinning and solution wet spinning, the technology is free of coagulating bath and solvent, the raw material cost and the production cost are greatly reduced, the preparation process is free of toxicity and pollution, and continuous preparation can be achieved.

Description

technical field [0001] The invention relates to the technical field of yarn production, in particular to a preparation method of an antibacterial conductive polypropylene yarn. Background technique [0002] The production process of melt-spun polypropylene is an important method for producing melt-blown polypropylene nonwovens. The emergence of smog weather and various epidemic diseases has made the control of air pollution once again the focus of social attention. In 2016, the China Textile Business Association released the group standard for "PM2.5 protective masks" (TAJ 1001-2015), which is the first mask standard officially released to the society in my country that can effectively protect against haze hazards, which also means that Masks without PM2.5 function will be eliminated from the market, and masks with high protection function will occupy the market. Compared with the mature dry spinning in the current market, melt spinning polypropylene has the advantages of s...
