Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to shorts and a method for manufacturing the same, and more particularly to shorts that are comfortable to wear and can be easily manufactured and a method for manufacturing the same.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, shorts have been manufactured by sewing together a number of body pieces with different curvatures to follow the curves of the body in order to improve the feeling of wearing the shorts. Then, in order to simplify the sewing process of the shorts, as in the shorts described in Japanese Patent Application Laid-Open No. 57-21501, a cylindrical knitted fabric was cut open, and the cut fabric was folded in half and sewn together. There are shorts manufactured by ζ, shorts such as those described in Jitsuma YS4S-84T No. 9, and shorts knitted with ribs with a slightly narrow center and sewn together.

However, the former type of shorts is manufactured by a method in which only one piece of shorts can be knitted in the second step, and furthermore, this method involves difficulty in cutting the cylindrical cloth.

In addition, the latter shorts have the disadvantage that the shorts fabric is a weft knitted fabric, so they tend to fray at cut points.

Further, Japanese Utility Model Application Publication No. 49-30110 discloses shorts manufactured using a fabric knitted by a warp knitting machine. The leg surrounding area is formed by providing a notch 10 at a predetermined location of the fabric, and since the fabric does not have a knitted part for forming a crotch area, the form as shown in Figure 2 of the same publication is used. In fact, as shown in Figure 7, the waist belt part A and the leg circumference opening are parallel, there is no three-dimensional clearance in the crotch part C, and the leg opening is insufficiently long. This makes it uncomfortable to wear.

Therefore, an object of the present invention is to provide shorts that are comfortable to wear and can be easily manufactured, and a method for manufacturing the shorts.

Only the section l'' has the side ends 6 of the 4° of the crotch section facing the double-knit section 5 for cutting, and another double-knit section for cutting that faces the crotch section 4 of the front section l of the shorts. It is organized so that it is connected via 5.

In addition, in the above knitting, the above 2
The rows are consecutively arranged via the first boundary part forming the linear leg enclosing part 8° on the back side L of the shorts, and the first row in the one row is connected only to the front part L of the shorts. The fabric is knitted so that a second boundary part constituting the concave leg enclosing part 8 of one example of the front part of the shorts is formed inside each of the boundary parts.

Further, as shown in FIG. 4, the back layer of the strip-shaped two-layer fabric A' has a shorts back part 1' on the back side of the shorts front part l in the surface layer marked with "-", and a shorts back part l' in the front layer. A front part 1 of the shorts is arranged on the back side of each shorts, and the shorts are knitted so that the back layer is the same as the front layer.

Next, the band-shaped two-layer fabric A° obtained as described above was cut by cutting the double knitted part 5 for cutting along the cutting line 10 and cutting at the first boundary, that is, the leg surrounding area 8°. rear,
By cutting at the second boundary, that is, the leg enclosing part 8, and inverting it so that the double knitted part 5 for cutting is located inside, the shorts 8 as shown in FIGS. 1 and 2 are obtained.

Moreover, FIG. 5 is a plan view showing a part of another example of the belt-shaped two-layer fabric from the surface layer side (or back layer side). It is formed in the same manner as the belt-shaped two-layer fabric shown in FIGS. 3 and 4, except that it is formed in the shape of a "ri".

Next, an embodiment of the second shorts of the present invention will be described with reference to FIG. 6 along with an embodiment of its manufacturing method.

The second shorts of the present invention differ from the first shorts in the following points, as is clear from the above description and FIG. 6 showing a part of the strip-shaped two-layer fabric forming the second shorts. ing.
