Abstract (en)
The present invention provides a latently crimped polyamide conjugate fiber which is suppressed in shrinkage rate variation and has few crepes or wrinkles due to dyeing speck or crimp unevenness, thereby having good quality. A crimped polyamide yarn according to the present invention is formed of a side-by-side type or eccentric core-sheath type polyamide conjugate fiber, and has a wet heat shrinkage stress variation rate of 150% or less.
