Abstract
A woven fabric includes a plurality of interlaced multifilament yarns, wherein at least one of the multifilament yarns includes first and second filaments having a pentagram cross-section, and the first and second filaments have a degree of modification between 1.4 and 2.6. The woven fabric has at least one surface calendered so that at least part of the multifilament yarns are compressed and the first and second filaments interlock with one another to retain low air permeability after repeated washing.
