Embodiment 1

[0060] The production process of the far-infrared polyester staple fiber of the present invention adopts recycled PET material as raw material, and the concrete steps are as follows:

[0061] (1) Pre-treatment: The recovered recycled PET material is washed with lye in sequence, decontaminated by de-alkali liquid in the centrifuge, automatically removed by the floating material separator, discharged from the ribbon washing machine, rinsed by the spray washing machine and then extracted. Pretreatment of material, centrifuge dehydration, conveyor belt delivery to pick table, pick table for manual material picking, pick out impurities, and then weigh and pack;

[0062] (2) Drum drying: first dry the recycled PET material after the treatment with a vacuum drum dryer for 6.5h, then add far-infrared masterbatch (Hairunhe Nano Materials Co., Ltd.), the final mass of the far-infrared masterbatch The fraction is 5%, the total drying time is 10h, and the drying is completed when the meas...

Abstract

The invention discloses a manufacturing technology for far-infrared polyester short fibers, which takes recycled PET (Polyethylene Terephthalate) as a raw material, and the recycled PET is processed sequentially through pretreatment, rotating drum drying, melt spinning, cooling formation, winding, drawing, curling, oil application, cutting and heat setting, so as to obtain finished products, wherein in the rotating drum drying step, the recycled PET is dried for 5.5 to 6.5 hours firstly, then far-infrared master batches are added, the final mass fraction of the far-infrared master batches ranges from 5 to 7 percent, the total drying time ranges from 9.5 to 10.5 hours, and far-infrared ceramic powders account for 19 to 21 percent in the far-infrared master batches; in the melt spinning step, the temperatures of a screw bolt and a spinning box body of a screw bolt extruder range from 268 to 278 DEG C, and cooling formation is carried out through circular air blow; in addition, the total drawing ratio is 3.0 to 3.5, the heat setting temperature ranges from 162 to 168 DEG C, and the heat setting time ranges from 8 to 12 minutes. The manufacturing technology can save cost and is beneficial to environmental protection, and the prepared finished products achieve good warmth retention and health protection properties.

Description

technical field [0001] The invention relates to a production process of polyester fiber, in particular to a production process of far-infrared polyester staple fiber. Background technique [0002] Polyester (that is, polyester fiber) is an important variety of synthetic fibers, and it is an important textile raw material. Synthetic fibers have recently been transformed from applicable to functional, and various functional processing needs to be performed on them during production. Among them, the far-infrared fiber can absorb light or emit far-infrared heat to promote blood circulation in the human body. It has far-infrared emission function, antibacterial function and heat preservation function. [0003] The conventional production process of far-infrared polyester fiber is mostly made by mixing and melting raw materials and far-infrared masterbatches and then spinning. The cost of raw materials is high, and it is a waste of resources and is not conducive to environmental ...
