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]

2. Description of the Related Art Conventionally, shorts have been manufactured by sewing together a number of body pieces each having a different curvature to follow the curve of the body in order to improve the feeling of wearing the shorts. In order to simplify the sewing process for shorts, a cylindrical knitted fabric is incised, and the incised fabric is folded in half and sewn together, as in the shorts described in JP-A No. 57-21501. There are shorts manufactured using the above-mentioned method, as well as shorts that are knitted with a rip knit and made slightly thinner in the center, and then sewn together, such as the shorts described in Japanese Utility Model Publication No. 48-8419.

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.

Furthermore, the latter type of shorts has the disadvantage that the shorts fabric is a weft knitted fabric, so it tends to fray at cut points.

Further, Japanese Utility Model 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 5, the waist belt part A and the leg opening are parallel, there is no three-dimensional clearance in the crotch part, and the leg opening is insufficiently long. It has a bad shape and is uncomfortable to wear.

[Means for solving problems]

As a result of various studies, the inventors of the present invention have obtained shorts that can achieve the above objectives by knitting a belt-shaped two-layer fabric using a jacquard double raschel machine, which is a warp knitting machine, and devising a knitting method. I found out that it can be done.

The present invention has been made based on the above knowledge, and is made by knitting with a Jacquard double Raschel machine, which is a warp knitting machine.
These shorts are made of a combination of two layers of fabric, each forming a front part of the shorts and a back part of the shorts. The leg surroundings formed by the side edges of the body part and the crotch part are formed with the same curvature, concave on the front side of the shorts, and convex on the back side of the shorts. To provide shorts, wherein the waist belt part and the body part on the front and back sides are joined at both ends in the wale direction, and the crotch parts on the front and back are joined at the side ends in the course direction. The above objective has been achieved.

In addition, according to the present invention (1), as a preferred method for manufacturing the shorts of the present invention, a combination of two layers of fabric, each forming a front part and a back part of the shorts, is produced using a jacquard double raschel machine, which is a warp knitting machine. A method of manufacturing shorts in which the leg surroundings are formed with the same curvature so that the front side of the shorts is concave and the back side of the shorts is convex, and the front side of the shorts or the back side of the shorts are arranged in series in the wale direction. Two layers of belt-like fabric are arranged on the left and right, and the waist belt parts are arranged on both ends of the course direction.One row of the front layer is made of double knitted fabric for cutting, with only the front part of the shorts being cut. In the rows of shorts, only the back part of the shorts has the side ends of their crotch parts facing the double knitting part for cutting, and also facing the crotch part of the front part of the shorts. The above-mentioned two rows in the surface layer are connected through another double knitted part for cutting, and the two rows in the surface layer are connected through a boundary part constituting the leg surrounding part, which is formed in a convex shape toward the front side of the shorts. , and the back layer is continuous in the weal direction so that it is formed identically to the front layer, with the back side of the shorts on the back side of the front side of the shorts, and the front side of the shorts on the back side of the back side of the shorts, respectively. The present invention provides a method for producing shorts, characterized in that the obtained belt-shaped two-layer fabric is cut at the double knitting section for cutting and at the boundary section.
