Abstract

The invention provides a production process of an antibacterial flame-retardant polyester filament, and relates to the technical field of polyester processing. The polyester filament comprises, by mass, 80-90 parts of polyethylene terephthalate, 10-12 parts of amino resin, 6-8 parts of calcium carbonate, 5-8 parts of titanium dioxide, 8-10 of graphene, 2-5 parts of trimethylolpropane, 20-25 partsof antibacterial agents, 5-6 parts of nano silver ions, 2-3 parts of coupling agents, 2-4 parts of dispersants, 2-4 parts of antimony trioxide, 4-5 parts of magnesium oxide, 2-3 parts of ethylenediaminetetraacetic acid ferric sodium salt and 1-2 parts of polyvinylpyrrolidone. The production process includes the steps of preheating and mixing, modification, auxiliary material mixing, spinning, antibacterial agent treatment, ultraviolet drying and the like. The preparation process has the advantages that the defects of the prior art are overcome; a plurality of antibacterial and flame-retardantcomponents are added for joint spinning, so that the service life of products is effectively prolonged, the resistance to bacteria and microorganisms is effectively enhanced, and the effect of safe flame resistance is achieved; the antibacterial agents are used for treatment, so that the antibacterial properties and stability of the products are effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of polyester processing, in particular to a production process of antibacterial and flame-retardant polyester yarn. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions—— Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. [0003] As a new generation of functional fiber, polyester is the simplest of the three major synthetic fibers, and the price is relatively cheap. In addition, it is durable, elastic, not easy to deform, corrosion-resistant, insulating, crisp, and easy to wash. Quick-drying and other characteristics are loved by people. [0004] Although polyester has many advantages,...
