Zusammenfassung:	PROBLEM TO BE SOLVED: To provide latent crimpable polyester conjugate staple fibers capable of giving not only high elasticity but also soft touch, and improved in texture, when forming a woven or a knitted fabric therefrom and to provide a nonwoven fabric comprising the latent crimpable conjugate staple fibers, excellent in elasticity, dimensional stability, and softness. SOLUTION: This polyester conjugate staple fibers is joined together eccentrically a polyester (A) comprising a trimethylene terephthalate unit as an essential repeating unit and a polyester (B) having different crimping properties from the polyester (A), and the cojugate staple fiber has ≥75% of crimp modulus of elasticity, and ≥50/25 mm of crimp expression under no load at 180°C.
