PROBLEM TO BE SOLVED: To provide a latently crimpable polyester conjugate fiber filament yarn excellent in stretchability, surface smoothness and softness when processed to a woven knitted fabric, and to provide woven/knitted fabric.SOLUTION: A bundling latently crimpable polyester conjugate fiber filament yarn is manufactured by bundling latently crimpable polyester conjugate fiber filaments to which (A) a high heat-shrinkable polyester containing terephthalic acid as a polybasic acid component, and ethylene glycol, a 2EO adduct of bisphenol A and diethylene glycol as a polyhydric alcohol component and (B) a low heat-shrinkable polyester containing polyester mainly comprising PET or an ethylene terephthalate unit are joined as a side-by-side type or an eccentric core-sheath type, and a percentage content of the 2EO adduct of bisphenol A is 5 to 15 mol%, the percentage content of diethylene glycol is 2.0 mol% or less, an actual crimp rate (C0(%)) and a latent crimp rate (C100(%)) of the yarn satisfy a prescribed range. |
