As a result, the stretch ratio was 20% and the elongation recovery rate was 85%, indicating that it had excellent stretchability and elongation recovery.
  • the processed yarn was used as a warp and a weft, and a green fabric having a density of 2Z2 twill with a density of 8 warps Z2.54 cm and a density of 72 wps 2.54 cm was obtained in the air jet room.
  • the greige fabric was subjected to the same dyeing processing as in Example 9 to obtain a cloth having a density of 115 pieces and a thickness of 2.54 cm and a density of 97 pieces and a density of 2.54 cm.
  • the resulting fabric is soft in texture, excellent in water absorbency and quick drying, with a stretch ratio of 23% in the longitudinal direction, a stretch recovery ratio of 85%, and a stretch ratio in the weft direction of 2%.
  • the elongation / recovery rate was 2% and the elongation / recovery rate was 8%.
  • the composite yarn composed of the polytrimethylene terephthalate fiber 84 dtex / 24 f of the pretwisted false twisted yarn and the copper ammonia rayon yarn 56 dtex / 30 f obtained in Example 7 was used.

  • the texture of the obtained fabric has a refreshing feeling unique to copper ammonia, a stretch ratio of 20% in the warp direction, a recovery ratio of 83% in elongation, and a stretch ratio of 1 in the weft direction. Excellent stretch with 9% growth recovery rate of 84% It had properties and elongation recovery.
  • the pretwisted false twisted yarn of 84 dtex / 24 f polymethylene terephthalate fiber obtained in Example 3 was subjected to 45 courses using a 32 gage circular knitting machine, A smooth knitted fabric was produced at a density of 44 mm. After scouring the smooth knitted fabric, it was dyed at 120 ° C. for 30 minutes using a Circular dyeing machine, and then dried. After drying, a final set was performed at 170 ° C. for 1 minute with a width to obtain a 49-course, 54-well cloth.
  • This fabric had a stretch ratio in the weft direction and an elongation recovery ratio of 200% and 98%, respectively, indicating good performance in both stretchability and elongation recovery. .
  • the twisted false twisted yarn, the composite twisted false twisted yarn, and the composite yarn of the present invention have a soft texture, and have excellent stretchability and elongation recovery properties. It is suitable.

Abstract

L'invention se rapporte à un fil à fausse torsion et à torsion préliminaire, qui se caractérise en ce qu'il comporte de multiples filaments de fibres de téréphtalate de polytriméthylène qui ont subi une torsion préliminaire dans un sens différent de celui de la fausse torsion. Le fil à fausse torsion et à torsion préliminaire de cette invention peut servir à la fabrication d'une étoffe qui est dotée d'excellentes caractéristiques d'extensibilité et de récupération à partir d'un état étiré et qui se caractérise par sa souplesse.
