PROBLEM TO BE SOLVED: To provide a latent-crimped polyester conjugate fiber providing a stretchable woven fabric providing very good dyed quality, and having both of soft feeling with bulking, and drape with massive feeling. SOLUTION: The latent-crimped polyester conjugate fiber is a conjugate fiber in which each single filament constituting a multifilament has a cross section shape obtained by cladding two kinds of polyester components having different viscosities in a side-by-side shape. The low-viscosity polyester component contains 1.5-8.0 mass% ceramic fine particles having 0.2-2.0μm average particle diameter and≥3.5 g/cm<SP>3</SP>density. The content of the ceramic fine particles in the high-viscosity polyester component is≤0.5 mass%. The recovery stress of the crimp of the multifilament is≥0.010 cN/dtex. COPYRIGHT: (C)2007,JPO&INPIT
