<p>PROBLEM TO BE SOLVED: To provide a stretchable conjugate yarn using a polylactic acid stereocomplex excellent in mechanical properties, durability, wet heat stability, and heat resistance.SOLUTION: A stretchable conjugate yarn is obtained by conjugating a polylactic acid filament composed of a polylactic acid resin in which at least a part of the carboxyl group terminals of a polylactic acid block copolymer constituted of a poly-L-lactic segment having L-lactic acid as a main component and a poly-D-lactic segment having D-lactic acid as a main component is blocked by an isocyanurate compound represented by general formula (1), and an elastic fiber, wherein at least one of R1 to R3 is glycidyl group and the remainings are functional groups such as H, a C1-C10 alkyl group, a hydroxyl group, or an allyl group.</p> |
