Nano-antibacterial deodorant PET (polyethylene glycol terephthalate) fiber and preparation method thereof

Abstract

The invention relates to a nano-antibacterial deodorant PET (polyethylene glycol terephthalate) fiber which comprises 1 to 10% of antibacterial special master batch particles and 90 to 99% of PET sections. The invention also relates to a preparation method of the nano-antibacterial deodorant PET fiber. The preparation method comprises the following steps: (1), drying the antibacterial master batch particles by a drying machine, mixing with the PET polyester sections, to obtain antibacterial special master batch particles; and (2), mixing the antibacterial special master batch particles with the PET sections, carrying out melt spinning on spinning equipment, so as to obtain the nano-antibacterial deodorant PET fiber. The nano-antibacterial deodorant PET and the preparation method have the following beneficial effects that through adding the nano-silver antibacterial master batch particles as an effective antibacterial component in the melt spinning process of the nano-antibacterial deodorant PET, the antibacterial and deodorant purposes are realized, the fiber has a significant inhibiting function to escherichia coli and staphylococcus aureus, and the antibacterial rate is higher than 90%. In addition, the fiber further has excellent mechanical property.

Description

technical field [0001] The invention belongs to the technical field of antibacterial materials, and in particular relates to a nano antibacterial and deodorant PET fiber and a preparation method thereof. Background technique [0002] PET (polyester) fiber has excellent physical and chemical properties. It is the fiber with the largest production volume and the widest application field among synthetic fibers. Its application range has been extended to various fields such as clothing, decoration and industrial use. Due to the poor water absorption of PET fibers, the free water content on the surface of PET fabrics is more, resulting in the growth rate of bacteria is higher than that of natural fibers with excellent water absorption properties; at the same time, the polymer part of PET fibers can be decomposed by microorganisms, and PET fabrics in During the processing, it is usually necessary to add substances that can be used as nutrients for microorganisms. When the external...

Problems solved by technology

Due to the poor water absorption of PET fibers, the free water content on the surface of PET fabrics is more, resulting in the growth rate of bacteria is higher than that of natural fibers with excellent water absorption properties; at the same time, the polymer part of PET fibers can be decomposed by microorganisms, and PET fabrics in During the processing, it is usually necessary to add substances that can be used as nutrients for microorganisms. When the external temperature and humidity conditions are ripe, PET fabrics are prone to breed a variety of microorganisms, resulting in discoloration of the fabric, spotting enzymes, and odors, etc.
