WIPO Patent Application WO/2021/117894
Kind Code:
A1
Abstract:
Provided is a woven fabric to be used in a medical device for chest disease, said woven fabric comprising ultrafine fibers and having high wear resistance. This woven fabric to be used in a medical device for chest disease, which comprises at least two kinds of polyester multifilaments having different single fiber finenesses, is characterized in that: among the at least two kinds of polyester multifilaments, polyester multifilaments having the largest single fiber fineness, comprising filaments with a single fiber fineness of larger than 0.5 dtex and not larger than 10 dtex and having a total fineness of 7-120 dtex inclusive are arranged as warps; among the at least two kinds of polyester multifilaments, polyester multifilaments having the smallest single fiber fineness, comprising filaments with a single fiber fineness of 0.5 dtex or smaller and having a total fineness of 7-120 dtex inclusive are arranged as wefts; the weaving shrinkage (crimping) rate measured in accordance with JIS L1096 8.7 B of the warps is 0.2-8.0% inclusive; the crimping rate of the wefts is 3.0-14.0% inclusive; and the crimping rate of the wefts is larger than the crimping rate of the warps.
