Patent number: 11116262Abstract: A garment includes a covering fabric; padding to be filled inside the covering fabric; and quilting stitches. The padding is constituted by polyester staple fibers including fibers having a circular outer peripheral cross section and has an open fiber structure. The fibers constituting the padding have an irregular diameter, and a smoothing agent is fixed to surfaces of the fibers. Thus, it is possible to provide a garment free from problems of uneven distribution of padding and having favorable water removability at the time of washing, quick dryability, and a favorable sliding property between fibers. This garment is suitable as a garment for sports to be washed repeatedly. Further, since the garment can be worn in a puffy state even when wet, it dries quickly by the body heat.Type: GrantFiled: December 3, 2015Date of Patent: September 14, 2021Assignee: Mizuno CorporationInventors: Atsushi Shiraishi, Junji Nakamitsu, Hiroki Sakurai, Masataka Kannoto, Takahiro Yoshimi
