ABSTRACT:
A high-tenacity polyhexamethylene adipamide fiber is described, which has (1) a formic acid relative viscosity of 50 to 150, (2) a tensile strength of at least 7.5 g/d, (3) an intermediate elongation not larger than 8% under 5.3 g/d, (4) a difference between elongation (%) at break and intermediate elongation (%) under 5.3 g/d of at least 6%, and (5) a shrinkage factor not larger than 5% under dry heat conditions at 160.degree. C. Preferably, the fiber has (6) an elongation of 12 to 20%, (7) a dimensional stability not larger than 13%, (8) a crystal orientation degree of at least 0.85 but not larger than 0.92, (9) a crystal perfection index of at least 60%, and (10) the peak temperature Tmax of the dynamic mechanical loss tangent (tan .delta.), as measured at a frequency of 110 Hz, satisfying the formula:
