Abstract
An absorbable multifilament draw-textured yarn having a bulky structure, and a manufacturing method and medical use thereof The absorbable multifilament draw-textured yarn is obtained by draw-texturing a multifilament made of an absorbable polymer and has bulkiness and a superior soft touch, which are the characteristics of draw-textured yarns. As a result of partially imparting a bulkiness of 150-1000% to the multifilament draw-textured yarn, it is possible to culture cells in the bulky structure, and the multifilament draw-textured yarn is suitable for cell delivery or drug delivery.
