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 centrifuge de-alkali solution, automatic impurity removal by floating material separator, discharge from ribbon washing machine, rinsed by spray washing machine and 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 treated recycled PET material with a vacuum drum dryer for 6.5 hours, and 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 measured water content is...
