Problems solved by technology

The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball. At present, the polyester filament on the market is mainly coarse denier fiber, and there are few fine denier fibers. Fiber is even rarer. With the improvement of living standards, the existing coarse denier fiber is difficult to meet the needs of consumers. In view of the above situation, the company successfully researched a super-soft and ultra-fine denier fiber on November 02, 2017. The preparation method of polyester filament is used to prepare ultra-soft and ultra-fine polyester filament, and an application for an invention patent was filed on November 02, 2017. After a long period of use, it was found that the ultra-soft and ultra-fine polyester filament prepared by this method The comfort, hand feel and visual or tactile effects of the fabrics processed from silk still have certain deficiencies, which cannot meet the needs of consumers. silk preparation method

Abstract

The invention discloses a method for preparing ultra-fine denier skin-affinity polyester filaments. The method comprises the steps of POY precursors, pre-interlace, first feeding roller, first deformation heat box, cooling plate, false twister, second feeding roller, intermediate interlace, second heat box, third feeding roller, oiling roller, DTY winding shaping and spinning cake inspection, wherein the intermediate interlace procedure can be removed, the temperature of the first deformation heat box is 165 DEG C-175 DEG C, the temperature of the second heat box is 130 DEG C-140 DEG C, the draft ratio is 1.58-1.68, the false twist ratio is 1.66-1.80, and the interlace air pressure is 0.03-0.15 MPA. The method has the advantages of being simple and easy to operate, fabric prepared by polyester filaments prepared by means of the method has the advantages of being more flexible, good in comfort performance and strong in visual and tactile feeling.

Description

technical field [0001] The invention specifically relates to a preparation method for producing polyester filaments, in particular to a preparation method for producing superfine denier skin-friendly polyester filaments. Background technique [0002] Polyester filament is made of polyester filament. Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation. - Polyethylene terephthalate (PET), fibers made by spinning and post-processing. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball. At present, the polyester filament on the market is mainly coarse denier fiber, and there are few fine denier fibers. Fiber is even rarer. With the improveme...
