| titleOfInvention | Polytrimethylene terephthalate fiber |
| abstract | A polytrimethylene terephthalate fiber composed of a polytrimethylene terephthalate (PTT) comprising not less than 95 mole% of a polytrimethylene terephthalate repeating unit and having an intrinsic viscosity of from 0.7 to 1.3, wherein the fiber satisfies the following features: (1) a degree of crystalline orientation of from 88% to 95%, (2) a peak value of dynamic loss tangent (tan delta ) max of from 0.10 to 0.15, (3) a peak temperature Tmax ( DEG C) of dynamic loss tangent 102 to 116 DEG C, (4) an elongation at break of from 36 to 50%, (5) a peak value of thermal stress being between 0.25 and 0.38 g/d, (6) a fiber to fiber dynamic frictional coefficient of from 0.30 to 0.50; and the PTT fiber having an excellent processability can be obtained through a drawing process in which the undrawn yarn can be stably drawn. The PTT fiber can be produced by melt-spinning PTT having an intrinsic viscosity of 0.7 - 1.3 at a withdrawal speed of 2,000 m/min or less to obtain a undrawn yarn, and then drawing and heat-treating the undrawn yarn by means of draw-twister. |
