  • Publication number: 20230042529
    Abstract: A garment 1 indudes an outer fabric and a lining 2. The lining 2 is a stretch fabric. An elastic thread is partially inserted in the stretch fabric in the body width direction, and an elastic thread insertion portion 4 contracts to make gathers 5. The stretch fabric is a one-way fabric that is stretchable in the body width direction. It is preferable that a plurality of elastic threads are inserted in the stretch fabric in parallel with each other, and the gathers 5 are oriented in the body length direction. Thus, the garment has a high heat retention effect by dividing the space between the garment and the human body into small areas to prevent warm air from escaping to the outside.

  • Patent number: 11116262
    Abstract: 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.

  • Publication number: 20180271182
    Abstract: A garment of the present invention is a garment (1) including: a covering fabric; padding to be filled inside the covering fabric; and quilting stitches (2a, 2b). The padding is a polyester staple fiber cotton 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 after repeated washing, fatigue, etc., and having favorable water removability at the time of washing, quick dryability, and a favorable sliding property between fibers even though synthetic fiber cotton is used as the padding. 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 with sweat, rain, snow, water, etc., it dries quickly by the body temperature and prevents the coldness of the body.
