Polyester glossy composite yarn and preparation method thereof

Abstract

The invention discloses polyester glossy composite yarn and a preparation method thereof. The polyester glossy composite yarn is prepared from the components in parts by weight of 80-90 parts of terephthalic acid, 20-30 parts of ethylene glycol, 10-15 parts of fluorine-containing acid, 10-13 parts of antioxidant, 10-15 parts of viscose-based chitin, 16-19 parts of modified Bi2O3 and 20-30 parts of coupling agent. A gearbox is arranged at the bottom end of a supporting rod; and through cooperation of a driving gear and a rotating gear, a deflection shaft rotates, then a thrust spring in a mounting block and a steel ball in a rolling groove block are utilized to make stirring blades on a rotating rod rotate, and a sliding relation between a stroke groove and a limiting block is utilized to make the rotating rod move up and down during rotation, therefore, raw materials at the lower part and the upper part can be fully mixed, so that the mixing efficiency is improved, the mixing time is shortened, and the production speed is accelerated.

Description

technical field [0001] The invention relates to the technical field of polyester yarn, in particular to a polyester yarn composite yarn and a preparation method thereof. Background technique [0002] Since the industrial production of polyester fiber, due to its high strength, good elasticity, excellent heat resistance and chemical resistance and excellent dimensional stability, it is widely used as textile raw materials, which largely relieves the natural fiber The situation of shortage has greatly promoted the development of the textile market, and polyester silk is polyester glossy silk, which is made of purified terephthalic acid (duPTA) or dimethyl terephthalate (DMT) and ethylene glycol. (EG) is a fiber-forming high polymer prepared by esterification or transesterification and polycondensation of raw materials—polyethylene terephthalate (PET), and fibers made by spinning and post-processing. [0003] At present, the production of this kind of polyester fiber composite...

AI Technical Summary

Problems solved by technology

[0003] At present, the production of this kind of polyester fiber composite yarn needs to mix raw materials such as dimethyl terephthalate and ethylene glycol, and the current mixing equipment is required to fully mix various raw materials. Mixing for a long time to ensure the quality of the composite yarn, but this method takes more time, so the efficiency is relatively low, and the vibration will be generated due to the rotation of the motor during the mixing, so after a long time, it will affect the have an effect on its lifespan
