Polyamide fibers having improved properties and their production |
abstract |
A polyamide fiber excellent in strength, which is characterized by having a relative viscosity of not less than 2.3 (measured on a 96% by weight sulfuric acid solution having a polyamide concentration of 10 mg/ml at 20 DEG C.), having an index of birefringence in section which satisfies the following relationship: DELTA nA- DELTA nB<0 (wherein DELTA nA is the index of birefringence of fiber at the position of r/R=0.9, DELTA nB is the index of birefringence of fiber at the position of r/R=0.0., R is the radius of the fiber section and r is the distance from the central axis of the fiber section), and showing the following physical constants: Index of birefringence of fiber ( DELTA n) (measured after 24 hours under the conditions of 30 DEG C. and 80% relative humidity) >/=50x10-3; Break strength >/=11 g/d; Fiber long period spacing value at length by small angle X-ray diffraction >/=100 ANGSTROM ; Specific gravity >/=1.140; Dry heat shrinkage </=15%. |
