Description

  The present invention relates to clothing such as trousers, a skirt or the like bottoms that can be stretched around the waist, and dresses such as skirts that are partly around the waist. Related to waist stretchable clothing such as waist stretchable bottoms that can prevent the occurrence of darts and improve the appearance by eliminating darts for handling floats, and can respond to various design needs It is.

  Here, “bottoms” (also referred to as bottoms in this specification, claims, and drawings) is a term for “bottoms”.) ”Is a term for tops that are clothing worn on the upper body. And trousers (pants) for men's trousers (pants) or women's trousers (pants), more specifically, slacks, boot-cut (full-length) pants, pantalon, croft (6 / 4-length) pants, Cropped pants, half pants, culottes, shorts, G bread (jeans), cotton buns, chinos, training trousers, and skirts. It means clothing to be worn.

  For bottoms such as sportswear, the waistband of flat rubber is used around the entire circumference of the waist belt to prevent falling off when worn or to respond to changes in flexion and waist circumference during exercise. Some are provided with rubber. For example, one of the inventors of the present invention also has a structure in which a waist rubber-filled bottoms, which has been previously applied, is worn by tightening around the waist with only the waist rubber (Patent Document 1).

  By the way, in the bottoms with a waist rubber of the invention which concerns on patent document 1, the upper end of a waist belt part and the upper end of a body part become a line which curves toward both sides from a front center and a rear center instead of a straight line. The waist belt part and the line in the vicinity thereof have a three-dimensional shape that fits around the waist. For this reason, according to the waist rubber-containing bottoms of the invention according to Patent Document 1, a smoother silhouette can be formed when worn.

Can be set at intervals of 6 to 8 cm, for example, and efficient production is expected.

By the way, since the upper end and lower end of flat rubber or the like have a linear shape, a conventional waist rubber or the like has a difference n between the upper end of the front waist belt portion 3A and the upper end of the rear waist belt 3B (FIG. 1 (a )) Is limited (average of about 3 to 4 cm), but the elastic belt core 5 according to the first embodiment has the upper end and the lower end extending from the front center direction and the rear center direction to both sides. Since it is cut into an arbitrary shape so as to have a curved shape that rises upward, the difference n between the upper end of the front waist belt portion 3A and the upper end of the rear waist belt 3B can be set large (for example, 4 .5 to 5.5 cm). Therefore, according to the waist stretchable bottoms 1 of the first embodiment, when worn and crouched or sat down, the back waist belt portion 3B and the tops are opened and the back is exposed. It can be expected to be prevented, and it becomes possible to cope with a low-waist type design with a shallow rise that is popular among young people.
Furthermore, conventional rubber rubber and other waist rubbers are difficult to bias-cut because they are unraveled by cutting, and the upper and lower ends of the rubber that are linearly shaped on both ends are stitched together and stitched together. Therefore, there is a limit in increasing the difference between the circumferences of the upper end and the lower end of the waist belt portion 3 (about 5 cm). However, according to the stretchable belt core 5 of the first embodiment, the waist belt It becomes possible to set large the difference of the circumference of the upper end of the part 3, and a lower end (for example, 8-10 cm). Therefore, according to the waist stretchable bottoms 1 of the first embodiment, it can be expected that a more beautiful silhouette along the waistline is formed.
