Abstract

The invention relates to an antimicrobial heating regenerated polyester fiber and a preparation method thereof. The preparation method comprises the steps: S1, preparing antimicrobial heating regenerated polyester master batches: mixing nanometer ZrO2 powder that is subjected to heating pretreatment, inorganic antimicrobial powder and 90-110 meshes regenerated polyester powder according to a weight ratio of 15-20:15-20:60-70, and thus forming the antimicrobial heating regenerated polyester master batches; S2, preparing antimicrobial heating regenerated polyester fibers: drying the antimicrobial heating regenerated polyester master batches and regenerated polyester chips to water content of less than 100-110 mg / kg, then mixing the dried regenerated polyester chips with the antimicrobial heating regenerated polyester master batches according to a weight percentage of 85-90wt%:10-15wt%, fusing through being extruded by a screw extruder, controlling the temperature of melt to be 280+ / -15 DEG C, firstly spinning precursors, then processing the precursors, and thus acquiring the antimicrobial heating regenerated polyester fibers, wherein the inorganic antimicrobial powder is 5% sodium zirconium phosphate copper-carried antimicrobial powder and 4.5% silver or zinc-carried apatite antimicrobial powder.

Description

technical field [0001] The invention belongs to the technical field of synthetic fiber production, and in particular relates to an antibacterial and heat-generating regenerated polyester fiber and a manufacturing method thereof. Background technique [0002] Antibacterial and heating fiber fabrics are significantly different from traditional fiber fabrics: traditional fiber fabrics mainly avoid heat loss and isolate bacteria by increasing the still air inside the fabric. , moisture, and temperature; the antibacterial heating fiber fabric uses its internal phase change material to regulate heat, antibacterial rather than isolation, and is a new thermal insulation and antibacterial fiber that can provide a comfortable experience for the human body. It can reduce changes in skin temperature and continue Thermal comfort, coupled with antimicrobial features, make the wearer more comfortable and healthy. [0003] Therefore, antibacterial heating fibers are widely used in ski clot...
