Embodiment 1

[0015] Such as figure 1 As shown, the preparation method of a kind of antibacterial polyester fiber described in the present embodiment is as follows: its components are 80 parts by mass parts of PET polyester chip, 20 parts of superfine bamboo cellulose micropowder. The slices in the PET polyester chip silo 1 are dried by the dryer and enter the feeding hopper 11, mixed with the ultrafine bamboo cellulose powder in the feeding hopper 21, and transported to the temperature of 265°C, 270°C, 280°C, 280°C, 280°C The screw extruder 3 performs melt extrusion, and the melted and mixed uniform raw materials pass through the filter 4, and the uniformly mixed melt is pressurized by the booster pump 6 and cooled by the melt cooler 7 through the conveying pipeline 5, and then the distributing valve The flow is diverted to each spinning box 8; metered by a metering pump, the polyester melt is injected into the spinning assembly, filtered, extruded, and then cooled by a ring blower to obta...

Embodiment 2

[0017] Such as figure 1 As shown, the preparation method of a kind of antibacterial polyester fiber described in the present embodiment is as follows: its components are 75 parts by mass parts of PET polyester chip, 25 parts of superfine bamboo cellulose micropowder. The slices in the PET polyester chip silo 1 are dried by the dryer and enter the feeding hopper 11, mixed with the ultra-fine bamboo cellulose powder in the feeding hopper 21, and transported to a temperature of 264°C, 269°C, 278°C, 278°C, 278°C The screw extruder 3 performs melt extrusion. The uniformly melted and mixed raw materials pass through the filter 4, and the uniformly mixed melt is pressurized by the booster pump 6 and cooled by the melt cooler 7 through the conveying pipeline 5, and then distributed to each spinning box 8 by the distribution valve; The metering pump is metered, the polyester melt is injected into the spinning assembly, filtered, extruded, and then cooled by the surrounding air to obta...

Abstract

The invention relates to the technical field of polyester fiber preparation, in particular to a preparation method of antibacterial polyester fiber. The method specifically comprises the steps as follows: (1) preparation of antibacterial polyester melt: the antibacterial polyester melt is prepared from 70-90 parts by mass of PET polyester chips and 10-30 parts by mass of bamboo cellulose micropowder; (2) preparation of polyester fiber; (3) winding forming of polyester filament. The preparation method of the antibacterial polyester fiber comprises a simple preparation process and is convenientto operate, and the prepared polyester fiber can have excellent antibacterial, deodorization and anti-ultraviolet functions through mixing of the superfine bamboo cellulose micropowder and the polyester melt. Fabric made of the polyester fiber has good wear comfort and appearance.

Description

technical field [0001] The invention relates to the technical field of polyester fiber preparation, in particular to a preparation method of antibacterial polyester fiber. Background technique [0002] Polyester is the world's largest and most widely used synthetic fiber, accounting for more than 60% of the world's synthetic fiber output. Applied to textiles such as clothing fabrics, household fabrics, industrial products, special fabrics, etc. With the sustained and rapid growth of the domestic economy and the improvement of residents' consumption capacity, the demand for polyester filaments is increasing. The increase in the output of polyester filament has made China gradually become the country with the largest output of polyester filament in the world. [0003] Polyester filament is the most processed synthetic fiber in textile fibers. Polyester filament has high strength, good heat resistance and stability. Therefore, polyester fabric has good wear resistance, wrinkl...
