Disclosed is a potentially elastic Interlaced-textured yarn including a
potentially crimped yarn and a composite filaments interlaced with each other,
and an elastic woven fabric produced using the same. The potentially elastic interlaced-textured
yarn is produced by interlacing the PET/PTT polyester-based potentially crimped
yarn with an ultrafine yarn having a monofilament fineness after the weight reduction
by alkali treatment of 0.01 to 0.5 deniers and a total fineness of 30 to 300 deniers.
At this time, the ultrafine yarn is selected from the group consisting of a sea-island
type composite filaments, a radial type composite filaments, and a yarn produced
through a direct spinning process. Furthermore, the potentially elastic interlaced-textured
yarn has elasticity of 15 to 40%, and the woven fabric has superior elastic recovery,
elasticity recovery, drape, and dyeability, in addition having soft, suede-like texture.
