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.

First claim

The invention claimed is:

1. A garment comprising:
a covering fabric;
padding to be filled inside the covering fabric; and
quilting stitches,
wherein the padding is constituted by a plurality of polyester staple fibers having a circular outer peripheral cross section and the padding has an open fiber structure,
each single fiber of the plurality of polyester staple fibers constituting the padding has an irregular diameter, with a difference between a maximum diameter and a minimum diameter of the irregular diameter in each of the polyester staple fibers being 2 μm to 20 μm based on an observation of a side face of each of the polyester staple fibers, and a smoothing agent is fixed to surfaces of each of the plurality of polyester staple fibers that imparts to the polyester staple fibers an increased sliding property between fibers relative to the sliding property between fibers of the polyester staple fibers without the smoothing agent,
the polyester staple fibers have a fineness of 1.1 dtex to 5.5 dtex and a length of 20 mm to 120 mm, and have a crimp change rate of 25% or less determined in accordance with JIS L 1015 (Test methods for man-made staple fibers) by the following formula:
crimp change rate =(F−E)/E×100,
where E represents the number of crimps before filling (number/2.5 cm), and F represents the number of crimps after filling (number/2.5 cm), and
a dewatering rate of the garment determined by the following formula is 24% or less:
dewatering rate (%) =D/C×100,
where C represents a weight of the garment before washing, and D represents a weight of the garment directly after dewatering.

2. The garment according to claim 1 , wherein an area surrounded by the quilting stitches is 3 cm 2 to 800 cm 2 .

3. The garment according to claim 1 , wherein a filling amount of the padding per unit area is 50 g/m 2 to 500 g/m 2 .

4. The garment according to claim 1 , wherein the polyester staple fibers are hollow.

5. The garment according to claim 4 , wherein a number of crimps of the hollow polyester staple fibers is 2 to 9/2.5 cm.

6. The garment according to claim 1 , wherein at least part of the padding is fixed to the covering fabric by the quilting stitches.

7. The garment according to claim 4 , wherein the polyester staple fibers have a hollow rate of 10% to 50%.

8. The garment according to claim 1 , further comprising a nonwoven fabric disposed inside the covering fabric together with the padding.

9. The garment according to claim 1 , wherein the garment has a Clo value (heat retaining property) of 2.00 or more.
