Benefits of technology

[0007]Sportswear of the present invention is sportswear that is worn with a tight fit to the surface of a wearer and that includes a stretch base fabric and partially a non-stretch or low-stretch material, wherein the non-stretch or low-stretch material is separately arranged in a region A that covers at least the back of the waist, a region B that includes rounded portions of the hips, and a region C that includes the back of the thighs, and the non-stretch or low-stretch material reinforces tension in a direction of extension of the hip joints.
[0008]Because sportswear of the present invention includes a stretch base fabric and partially a non-stretch or low-stretch material, wherein the non-stretch or low-stretch material is arranged separately in a region A that covers at least the back of the waist, a region B that includes rounded portions of the hips, and a region C that includes the back of the thighs to reinforce tension in a direction of extension of the hip joints, it is possible to exert a function of lifting up the back of the thighs from the buttocks, suppress the bending of the lower body with respect to the upper body, and provide a function of smoothing protruding body parts while satisfying a function of high mobility.
[0009]That is to say, by arranging a non-stretch or low-stretch material separately in the regions A to C, the tension

Problems solved by technology

Conventional swimsuits have been designed focusing on reducing the friction resistance of the material (see, for example, Japanese Patent No. 2715088, JP 2004-292962A, WO 2007/142232), but nothing has been done to reduce the shape resistance, which accounts for a high percentage of the water resistance.
Also, bending of the lower body with respect to the upper body, which

example 1

[0067]As shown in FIGS. 1A and 1B, a region A (2a, 2b) that covers at least the back of the waist, a region B (3a, 3b) that includes the rounded portions of the hips, and a region C (4a, 4b) that includes the back of the thighs were separately arranged on the surface of a stretch base fabric 1 by providing a non-stretch or low-stretch sheet by attaching a transfer sheet by thermal pressing so as to reinforce tension in the direction of extension of the hip joints.

[0068]As the stretch base fabric, a fabric woven in a plain weave with a weight per unit area of 110 g / m2 was used. For the warp yarn, a yarn made by covering 44 dtex (decitex) polyurethane (Pu) filaments with 33 dtex (decitex) nylon filaments with a filament number of ten was used, and for the weft yarn, a yarn made by covering 44 dtex (decitex) polyurethane (Pu) filaments with 33 dtex (decitex) nylon filaments with a filament number often was used. The number of warp yarns per inch was 161, and the number of weft yarns pe...

[0071]A pair of half leggings was produced in the same manner as in Example 1 except that the half leggings were configured as shown in FIGS. 2A and 2B.

[0072]Five male competitive swimmers were instructed to wear the half leggings of Comparative Example 1 and Examples 1 and 2, and to respond to the items shown in Tables 1 to 3. Each item was rated on a scale of 1 to 5, with 5 being strongly agreed, 4 being mostly agreed, 3 being somewhat agreed, 2 being somewhat disagreed, and 1 being disagreed.

[0076]A one-piece type swimsuit was produced in the same manner as in Example 1 except that the swimsuit was configured as shown in FIGS. 9A and 9B. As in Examples 1 to 2, five female competitive swimmers were instructed to wear the swimsuit and to respond to the items shown in Table 5.

Abstract

Sportswear (10) that is worn with a tight fit to the surface of a wearer and that includes a stretch base fabric (1) and partially a non-stretch or low-stretch material, wherein the non-stretch or low-stretch material is arranged separately in a region A (2a, 2b) that covers at least the back of the waist, a region B (3a, 3b) that includes rounded portions of both hips and a region C (4a, 4b) that includes the back of the thighs, and the non-stretch or low-stretch material reinforces tension in a direction of extension of the hip joints, whereby it is possible to provide sportswear that suppresses the bending of the lower body with respect to the upper body, has a function of smoothing protruding body parts and satisfies a function of high mobility.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to sportswear that is worn with a substantially tight fit to the surface of a wearer.[0003]2. Description of Related Art[0004]Swimsuits with low water resistance are required for competitive swimming. Water resistance can be divided into fluid friction resistance between water flowing along the body surface and the body or swimsuit, and shape resistance that depends on the body shape. Conventional swimsuits have been designed focusing on reducing the friction resistance of the material (see, for example, Japanese Patent No. 2715088, JP 2004-292962A, WO 2007 / 142232), but nothing has been done to reduce the shape resistance, which accounts for a high percentage of the water resistance.[0005]In order to reduce the shape resistance, it is required to flatten protruding body parts, such as hips and women's breast curves, to the highest degree possible. Also, bending of the lower body with respec...
