Problems solved by technology

[0004] In the above technology, although this kind of high-elastic flame-retardant polyester has overcome the disadvantages of poor air permeability and poor absorption of polyester, the elasticity of polyester is poor due to the addition of phosphate starch and diatom mud as flame retardants, making the obtained The fabric is not elastic enough. If this polyester is used in tight-fitting sportswear, the athlete will feel tight and uncomfortable when wearing it.

Abstract

The invention relates to the field of polyester yarn preparation, in particular to a high-elasticity polyester yarn and a preparation method thereof. The high-elasticity polyester yarn is prepared from, by mass, 60-80 parts of polyester masterbatch, 25-30 parts of polylactic acid fiber powder, 5-10 parts of thermoplastic polyurethane elastomer, 2-5 parts of a compatilizer, 12-18 parts of tree ashand 2-3 parts of an antioxidant. The preparation method includes steps: pretreating the materials according to the parts by mass; mixing the materials to obtain a mixture A; melting and extruding themixture A to obtain a melt B; cooling the melt B to obtain polyester filaments C; subjecting the polyester filaments C to stretching and setting to obtain polyester filaments E; coating the polyesterfilaments E with oil liquid, and subjecting the polyester filaments E to stretching and setting; finally twisting the polyester filaments E to obtain the yarn, and rolling up. The high-elasticity polyester yarn and the preparation method thereof have the advantage that the polyester yarn prepared according to the method is high in elasticity and can be applied to preparation of tight-fitting sportswear.

Description

technical field [0001] The invention relates to the technical field of polyester yarn preparation, more specifically, it relates to a high-elastic polyester yarn and a preparation method thereof. Background technique [0002] Polyester yarn is a yarn spun from polyester. Polyester is one of the important varieties of synthetic fibers. It uses purified terephthalic acid or terephthalate and ethylene glycol as raw materials through esterification or transesterification. Polyethylene terephthalate (PET) obtained by polycondensation reaction, fiber obtained by spinning and post-processing. [0003] In the prior art, the Chinese invention patent application document with the application number 201610568722.6 discloses a high-elastic flame-retardant polyester, which is made according to the following proportions by weight: 5-15 parts of polyethylene glycol, 10-30 parts of purified p-phenylene Diformic acid, 10-25 parts of plant fiber, 5-15 parts of phosphate ester starch, 5-15 pa...
