Abstract:
1. A latently crimpable conjugate fiber, comprising: a conjugate fiber that includes wherein a surface of the first component is exposed with an exposed length viewed in cross section of not less than 20% relative to a peripheral length of the fiber, wherein the fiber has: (1) a monofilament dry heat shrinkage percentage of not less than 50%, which is determined according to JIS-L-1015 (dry heat shrinkage percentage) at a temperature of 100° C. under an initial tension of 0.018 mN/dtex (2 mg/d) for a time of 15 minutes; and (2) a monofilament dry heat shrinkage percentage of not less than 15%, which is determined according to JIS-L-1015 (dry heat shrinkage percentage) at a temperature of 100° C. under an initial tension of 0.450 mN/dtex (50 mg/d) for a time of 15 minutes.
