Abstract

The invention provides a making method of a polyester yarn and a superfine denier polyester yarn. The making method of the polyester yarns comprises the steps: POY protofilament making, pre-networking, feeding with a first feeding roller, processing with a first deformation heat box, processing with a cooling plate, twisting with a false twister, feeding with a second feeding roller, forming of amiddle network, shaping with a second shaping heat box, processing with a shaping overfeeding roller, oiling with an oiling roller, DTY winding shaping and spinning cake checkout. According to the making method, 12 dtex / 7f of POY is processed into the 8 dtex / 7f of DTY by adopting a special false twisting process, so that the breakage rate is greatly reduced in the knitting process, and the production efficiency and the product quality are effectively improved. The fabric processed by the product is very good comfort, hand feeling and visual or touch effects, and has the light and ethereal characteristics in style.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation method of polyester yarn and superfine polyester yarn. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the diversity, comfort and functionality of clothing are becoming more and more extensive. Fiber fine denier and functionalization are an important direction for the development of differential fibers, and also the main development trend of polyamide fiber spinning. Fabrics processed from conventional polyester varieties have limitations in elasticity, softness, air permeability, and functionality. Due to its unique characteristics, polyester ultra-fine denier fiber has relatively thin filaments and high bending strength. The woven fabric has softness, good air permeability, light and thin fabric, and good comfort. Due to the thinner filaments of ultrafine denier fibers, the production process...
