<p>A poly(trimethylene terephthalate) fiber which may be produced by a two stage process comprising low speed spinning and drawing, wherein winding conditions for undrawn fibers and the atmospheric conditions and the time for holding them are controlled within respective specific ranges. The practice of the two stage process under specified conditions as mentioned above allows inhibiting the shrinkage of undrawn fibers over time and the deformation of an undrawn fiber package due to the shrinkage and holding the unwinding tension at a constant level, which results in a good vein of the drawing and then in the production of a high quality poly(trimethylene terephthalate) fiber. The poly(trimethylene terephthalate) fiber has a high toughness and a uniform fineness and is excellent in the homogeneity of dyeing, and is significantly useful for clothing.</p> |
