Problems solved by technology

Among the Taslan processed yarns used in the existing uniform materials, it is more common that the core and sheath all use polyester as the processing raw material. For example, patent CN101200830B discloses a polyester imitation cotton filament and its fabric, using the Taslan processing method, polyester POY is used as the sheath filament, and polyester FDY is used as the core filament. Because polyester POY has the characteristics of easy dyeing, the overall dyeability of the formed yarn is better, but the core filament fineness is larger than the sheath filament fineness, and the sheath filament monofilament fineness is lower. Will affect the dyeing properties of fabrics formed from this yarn

Abstract

The invention discloses polyester composite yarn and densely stained fabric which is made of the polyester composite yarn. The composite yarn is air textured yarn which is formed by core yarn and sheath, wherein full-dull or semi-dull polyester fully-drawn yarn is adopted to serve as the core yarn, and full-dull or semi-dull polyester pre-oriented yarn serves as the sheath yarn; the yarn-length different between the sheath yarn and the core yarn is 11-30%, the total denier of the sheath yarn is greater than that of the core yarn, the denier of a single core-yarn filament is 1.2-7.5 Denier, and the denier of a single sheath-yarn filament is 1.3-12.5 Denier. The polyester composite yarn is fluffy in outer layer, stiffening in inner layer, good in elastic resilience and high in dye absorption rate, the densely stained (deeply stained) fabric which is made of the polyester composite yarn can be used in women' s and men's model clothes, super-black full dresses, Middle-East national costume and the like.

Description

technical field [0001] The invention relates to a polyester composite yarn and a deep-dyed fabric prepared therefrom. More specifically, the present invention relates to a polyester air textured yarn and a deep-dyed fabric prepared therefrom with excellent dark effect and no color difference. Background technique [0002] Since its inception, polyester fiber has been the most productive synthetic fiber in the chemical fiber industry. With its low price, moderate resilience, good wrinkle resistance and crispness, it is widely used as clothing fabric fiber. Among them, polyester black dense dyed fabrics are used as materials for men's and women's dresses in Japan, South Korea, Taiwan and other countries and regions. The sales price is relatively high and the profit is considerable. This kind of polyester black intensive dyed fabric is mainly woven with polyester fully drawn yarn (FDY) or polyester false twisted yarn (DTY), and the color development after dyeing is not very id...
