(1) Strong twisted yarn woven elastic bandage: Long-staple cotton strong twisted yarn is used as warp, and cotton thick special carded yarn is used as weft to weave dense and sparse plain weave fabric. Before weaving, sizing the strong twist warp yarn to fix the twist so that the weft yarn can pass through the shed.
