Embodiment 1

[0044]The ordinary polyester PET (SD) filament POY with a monofilament fineness of 0.89dtex and the cationic dyeable polyester (CD) filament with a monofilament fineness of 1.96dtex are merged and fed to the first roller, and then stretched by hot needles. The elongation ratio is 1.162, and then passes through the second roller, and then enters the hot box for heating. The temperature of the first hot box (1HT) is 175°C. It is cooled by the cooling plate, and then enters the false twisting disc for false twisting deformation, where the untwisting tension is the same as The ratio of twisting tension is 0.53, and then it passes through the nozzle for intertwining and then winding forming. Among the mixed filament yarns obtained by winding, the measured number of hairiness lengths of 1 mm or more was 813 pieces / 1000 meters, and the measured number of hairiness lengths of 2 mm or more was 29 pieces / 1000 meters. After dyeing the fabric made from the hairiness melange false-twisted ...

Embodiment 2

[0046] The ordinary polyester PET (SD) filament POY with a monofilament fineness of 1.96dtex and the cationic dyeable polyester (CD) filament with a monofilament fineness of 0.89dtex are combined and fed to the first roller, and then stretched by hot needles. The elongation ratio is 1.162, and then passes through the second roller, and then enters the hot box for heating. The temperature of the first hot box (1HT) is 175°C, and it is cooled by the cooling plate, and then enters the false twisting disc for false twisting deformation, where the untwisting tension is the same as The ratio of twisting tension is 0.53, and then it passes through the nozzle for intertwining and then winding forming. Among the mixed filament yarns obtained by winding, the number of measured hairiness lengths of 1 mm or more was 900 pieces / 1000 m, and the number of measurement numbers of hairiness lengths of 2 mm or more was 35 pieces / 1000 m. After dyeing the fabric made from the hairiness melange fal...

Embodiment 3

[0048] The ordinary polyester PET (SD) filament POY with a monofilament fineness of 0.89dtex and the cationic dyeable polyester (CD) filament with a monofilament fineness of 1.96dtex are merged and fed to the first roller, and then stretched by hot needles. The elongation ratio is 1.162, and then passes through the second roller, and then enters the hot box for heating. The temperature of the first hot box (1HT) is 175°C, and it is cooled by the cooling plate, and then enters the false twisting disc for false twisting deformation, where the untwisting tension is the same as The ratio of twisting tension is 0.30, and then it passes through the nozzle for intertwining and then winding forming. In the mixed fiber yarn obtained by winding, the measured number of hairiness length 1mm or more was 350 pieces / 1000m, and the measurement number of hairiness length 2mm or more was 15 pieces / 1000m. After dyeing the fabric made from the hairiness melange false-twisted processed yarn, the p...

Abstract

The invention discloses a hairiness color-mixed false-twist processed yarn which comprises polyester filaments A and polyester filaments B. The polyester filaments A and/or the polyester filaments B are/is of a slub structure, and part of slubs in the slub structure are cut off to form hairiness. The number of hairiness with the diameter larger than 2 mm is 100/1000 m or below. The anti-pilling effect of the hairiness color-mixed false-twist processed yarn is good. Meanwhile, after being dyed, the fabric made of the false twist processed yarn has natural stripe feelings with different colors, and the color mixing effect is good.

Description

technical field [0001] The invention relates to a false-twisted processed yarn and a preparation method thereof, in particular to a false-twisted processed yarn with hairiness on the processed yarn and a natural pattern feeling of different colors after dyeing and a preparation method thereof. Background technique [0002] Cotton fiber is a natural fiber of traditional spinning, which has the advantages of fluffy, soft touch, soft hand feeling and soft surface luster. With the continuous increase of market demand, there is a certain pressure on the supply of cotton fiber. At the same time, cotton planting is easily affected by the climate, which makes the supply of cotton raw materials very unstable. Therefore, it is very necessary to use chemical fibers instead of cotton fibers to produce cotton-like fibers that have the advantages of cotton and can solve the shortcomings of cotton. [0003] Although there are various forms of cotton-like fiber products in the market, most...
