Example Embodiment

[0044] Example 1

[0045] Use 56dtex-24f-semi-dull PET-FDY as the core wire, 93dtex-36f-semi-dull PET-POY as the sheath wire, and feed it into the air deforming nozzle. The processing conditions are as follows: core wire overfeed rate 5%, sheath wire overfeed With a rate of 16%, a processing speed of 350m / min, and a hot plate temperature of 180°C, the 165dtex-60f-PET composite yarn of the present invention was prepared with a strength of 1.51cN / dtex and an elongation of 35.1%. The parameters are shown in Table 1.

Abstract

The invention discloses a polyester composite yarn and a deep-dyed fabric prepared therefrom. The composite yarn is an air textured yarn formed by using full-dull or semi-dull polyester fully-drawn yarn as the core yarn and fully-dull or semi-dull polyester pre-oriented yarn as the sheath yarn. The length difference is 11% to 30%, and the total fineness of the aforementioned sheath filaments is greater than the total fineness of the core filaments. The single filament fineness of the core filaments is 1.2 to 7.5 deniers, and the single filament fineness of the sheath filaments is 1.3 to 12.5 deniers you. The polyester composite yarn of the present invention has a fluffy outer layer, a stiff inner layer, good reversibility (rebound elasticity), and a high dye absorption rate. The densely dyed (deeply dyed) fabric made by it can be used for women's and men's fashion, special black Dresses, and Middle Eastern national costumes, etc.

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...
