Embodiment 1

[0051] Polyethylene terephthalate (high-strength part) with an IV of 0.65dl / g and polyethylene terephthalate (low-strength part) with an IV of 0.50dl / g are respectively spun to produce high Strength POY and low strength POY, the obtained low strength POY is combined with the high strength POY at the yarn guide after external drafting, enters the false twist zone at 160~240℃, and after interlacing, the monofilament size is obtained 0.49dtex hairy composite yarn (140T-288-DTY).

[0052] The hairiness-like composite yarn obtained by the above method has a strength and elongation product of 8.2, and the number of hairiness of the hairiness-like composite yarn with a length of 1 mm and above is 735 pieces / 10 meters. The fusion rate of the hairy composite yarn is 3.2%, and the anti-pilling effect is level 3.

Embodiment 2

[0054] Polyethylene terephthalate (high-strength part) with IV of 0.75dl / g and polyethylene terephthalate (low-strength part) with IV of 0.50dl / g are respectively spun to make high Strength POY and low strength POY, the obtained low strength POY is combined with the high strength POY at the yarn guide after external drafting, enters the false twist zone at 160~240℃, and after interlacing, the monofilament size is obtained 0.49dtex hairy composite yarn (140T-288-DTY).

[0055] The hairiness-like composite yarn obtained by the above method has a strength and elongation product of 12.3, and the number of hairiness of the hairiness-like composite yarn with a length of 1 mm and above is 712 per 10 meters. The fusion rate of the hairy composite yarn is 3.0%, and the anti-pilling effect is level 3.

Embodiment 3

[0057] Polyethylene terephthalate (high-strength part) with an IV of 0.90dl / g and polyethylene terephthalate (low-strength part) with an IV of 0.50dl / g are respectively spun to make high Strength POY and low strength POY, the obtained low strength POY is combined with the high strength POY at the yarn guide after external drafting, enters the false twist zone at 160~240℃, and after interlacing, the monofilament size is obtained 0.49dtex hairy composite yarn (140T-288-DTY).

[0058] The hairiness-like composite yarn obtained by the above method has a strength and elongation product of 15.8, and the number of hairiness of the hairiness-like composite yarn with a length of 1 mm and above is 769 / 10 meters. The fusion rate of the hairy composite yarn is 3.8%, and the anti-pilling effect is level 3.

Abstract

The invention discloses a hairiness-shaped composite yarn. The composite yarn contains high-strength yarns and low-strength yarns, a part of low-strength yarn monofilaments are cut off, or a part of low-strength yarn monofilaments and a part of high-strength yarn monofilaments are cut off to form hairiness, the product of strength and elongation of the hairiness-shaped composite yarn is 5-30, andthe hairiness-shaped composite yarn has a fusion effect. The hairiness-shaped composite yarn has the same degree of hairiness as a cotton yarn, is excellent in strength, elongation and pilling resistance, and is suitable for preparing various fabrics with the feeling similar to that of the hairiness of the cotton yarn.

Description

Technical field [0001] The invention relates to a hairy composite yarn containing high-strength yarns and low-strength yarns. Background technique [0002] Cotton-like polyester fiber is a major subject that the current polyester fiber developers are working hard to promote. The cotton imitation technology of polyester fiber needs to start from imitating the appearance and performance of cotton yarn. The cotton yarn feel, tightness, gloss, moisture absorption, anti-pilling and dyeing performance of polyester fiber are all in the cotton imitation technology. What needs to be considered. [0003] Although there has been a technology to obtain intertwined mixed filaments with ultra-fine multifilaments such as sea-island type and split type as the sheath yarn and high-shrinkage yarn as the core yarn, hairiness is generally forced to be produced by the raising process in the dyeing finishing process. As the production cost becomes higher, the hairiness obtained will be concentrated on...
