2. Description of the Related Art Conventionally, shorts have been manufactured by sewing a large number of body pieces having different curvatures so as to follow a curve of a body in order to improve a wearing feeling. Then, in order to simplify the sewing process of the shorts, a cylindrical knitted fabric is incised as in the shorts described in JP-A-57-21501, and the cut knitted fabric is folded and sewn. Shorts manufactured as described above, and shorts described in Japanese Utility Model Application Laid-Open No. 48-8419, in which the center is slightly thinned by rib knitting and stitched, and the like.

However, the former shorts are manufactured by a method capable of knitting only one piece in one process, and this method involves difficulty in cutting a cylindrical cloth. Further, the latter shorts have a disadvantage that the cut portions are easily frayed because the shorts fabric is a weft knitted fabric.

Japanese Utility Model Laid-Open No. 49-30110 discloses shorts knitted by a warp knitting machine.
As can be inferred from the description in FIG. 1 of the publication, the shape is not the same as that shown in FIG. 2 of the publication, but the legs are surrounded (a portion constituted by the notch 10 in FIG. 1 of the publication). Is the band part
Since it became a straight line parallel to 3 and 4, it was difficult to exhibit a desirable wearing feeling.

Accordingly, an object of the present invention is to provide a method for producing shorts which is excellent in a feeling of wearing and can be easily produced.

[Means for solving the problem]

As a result of various studies, the present inventors knit a shorts composite fabric of a specific shape using a warp knitting machine, cut this shorts composite fabric into shorts fabric that can form one short, fold it into two, and sew it. Alternatively, it has been found that shorts that can achieve the above object can be manufactured by bonding.

The present invention has been made on the basis of the above knowledge, and in a knitting machine, two upper and lower bases each having the same length are used.
The front waist band forming part, the front body forming part, the crotch part forming part, the rear body forming part and the rear waist band forming part are sequentially connected in series in the course direction in a medium constriction shape in which the upper bases of the equilateral trapezoids are butt-connected. And a shorts fabric having a form in which the crotch portion forming portion is disposed in the middle constricted portion, in which n (n is 3 or more) or n-1 shorts fabrics are connected in series in the course direction, and n shorts fabrics are connected in series. And the combined fabric of the shorts fabrics in series with the n-1 pieces are alternately and continuously arranged in the wale direction, and are integrally knitted. At this time, the front and rear waistband forming portions and the crotch portion forming portion are formed. Are arranged in series in a direction perpendicular to the wale direction, and the elastic yarns having a high elongation recovery force (the elongation recovery force at the time of 50% elongation; the “elongation recovery force” in this specification are all synonymous) are used. Organize And it allows to manufacture a shorts composite fabric the shorts fabric is bonded integrally to many aspect,
Then, the shorts composite fabric is cut off for each shorts fabric, and then the shorts fabric is folded in two so that the front waistband forming portion and the rear waistband forming portion overlap each other, and both ends thereof It is intended to provide a method for manufacturing shorts in which part or all of both ends of the front body forming part and the rear body forming part are sewn or adhered.

Then, the shorts composite fabric A 'is obtained.

FIG. 1 shows, as shorts composite fabric A ', combined fabrics 10 and 2 in which three shorts fabrics A are arranged in series in the course direction q.
In the present invention, an example is shown in which, in the present invention, shorts dough A in the course direction q is used as the bond dough 10 'in the wale direction p. (N is 3 or more, preferably 3 to 6) in series, and the knitted fabric 10 'can be knitted in a depth of n-1 in the wale direction p. And the connecting fabric 10 'may be alternately connected in series, and there is no limitation on the number of connected fabrics in the wale direction p.

In addition, each shorts fabric A constituting the shorts combination fabric A ′ has a predecessor in the middle constriction portion of the crotch portion forming portion 3 in order to form a short constriction shape (substantially drum-shaped) that can form a shorts B having excellent wearing feeling. The angle α between one side edge of the back body forming section 2 and one side edge of the back body forming section 4 is preferably 110 to 150 °.

Next, a preferred embodiment of each shorts cloth A will be described with reference to FIG.

Since the front waistband forming part 1 and the rear waistband part 5 form the waistband of the shorts B, they may be knitted so as to be suitable as a waistband (about 1 to 4 cm in width), and are preferable. The yarn is knitted (knitted) with elastic yarn so that the elongation recovery force becomes 200 to 500 g. As this yarn, a polyurethane yarn (described later) knitting the crotch portion forming part 3 is continuous. Used as is. The length a in the wale direction p of the front waistband forming portion 1 and the rear waistband forming portion 5 is approximately 1/2 of the length around the waist of the target shorts, and is usually 15 to 30 cm.

Further, the front body forming part 2 and the rear body forming part 4 are for forming the forward body and the rear body of the shorts B, and in order to improve the fit with the body, a flexible material having elasticity, for example, 10 to 210 denier polyurethane thread 5 to 20
About 30% to 100S cotton yarn or polyester,
It is preferable to use a cloth cross-knitted with nylon or the like, or a twisted yarn of polyurethane yarn, cotton, synthetic fiber, or the like. The fabric weight of the front body forming part 2 and the back body forming part 4 is 100 to 150 g. / m ² is preferable. Further, in order to give the hip part a favorable wearing feeling when worn, the length of the front body forming portion 2 in the course direction q is smaller than the length of the rear body forming portion 4, preferably 20 to 30% smaller. .

In addition, knitting such that the extension recovery force of the front body forming portion 2 in the wale direction becomes 300 to 450 g and the expansion recovery force of the rear body forming portion 4 becomes 200 to 350 g further improves the wearing feeling. preferable.

According to the present invention, the width of the shorts cloth A and the bonding cloth 10 in the bonding cloth 10 are adjusted according to the present invention as shown in FIG. ′ Can be easily changed by changing the direction of the shorts cloth A in FIG.

The crotch portion forming portion 3 forms the crotch value of the shorts B. In the case of the manufacturing method of the present invention, the waist band forming portions 1 and 5 in the wale direction p.
Since it is formed in series with the waist band forming portions 1 and 5, the yarns used for knitting the waist band forming portions 1 and 5 are knitted by performing a stitch adjustment, and the front body forming portion 2 and the back body forming portion 4 are knitted. In the course direction q, it is preferably formed by knitting a 30 to 560 denier polyurethane yarn in a stretched state over a width of 8 to 13 cm in the course direction q, and knitting such that the polyurethane yarn has a stretch recovery force of 300 to 500 g. preferable.

However, in the present invention, since the shape of the shorts fabric A is previously formed into a medium constricted shape so as to obtain shorts excellent in a feeling of wearing, if the stretch recovery force is sufficient to form a waistband. No problem. Further, it is more preferable that the crotch portion forming portion 3 has a floating structure such as pile knitting, which easily expands and contracts, and the pile length in the case of pile knitting is preferably about 1.0 to 3 mm.

Further, as shown in FIG. 1 and FIG. 2, a double knit portion, that is, a holding portion 6 such as a suction pad is knitted at both ends along the wale direction p on the inner surface side of the crotch portion forming portion 3. If it is used, it can be used as a pad-attached short for sanitary or incontinent persons.

Then, as described above, the shorts cloth A having a predetermined form
The shorts composite fabric A ′ obtained by knitting a large number of pieces horizontally and horizontally is cut for each shorts fabric A. This cutting is preferably performed by a cutting device having a cutting blade formed in advance in correspondence with the shorts composite fabric A 'including a predetermined number of shorts fabrics A.

Each shorts fabric A obtained by cutting the shorts composite fabric A 'is formed in a medium constriction shape in advance, and furthermore, the crotch portion forming portion 3 is further contracted by the elasticity of the crotch portion forming portion 3 so that the medium constriction is further reduced. It has a shape (substantially drum-shaped), and the length of the crotch portion forming portion 3 is 8 to 13 cm, preferably 5 to 13 cm.
Change to 10cm. The shorts cloth A does not fray at the cut portion as a characteristic of the warp knitted fabric.

Thereafter, each shorts fabric A obtained as described above is obtained.
The front waistband forming portion 1 and the rear waistband forming portion 5 are folded in two without any treatment on the cut portion so that the front waistband forming portion 5 and the rear waistband forming portion 5 are overlapped with the absorbing pad holding portion 6 inside. Then, a part or the whole is sewn or adhered to both ends thereof and both ends of the front body forming part 1 and the back body forming part 5 respectively. As a result, shorts B having a shape as shown in FIG. 3 are manufactured.

When the shorts composite fabric A ′ is manufactured, the forming portions 1 to 5 may be knitted according to the form of the target shorts fabric AA, and knitted using an elastic yarn having a high elongation and recovery force. Since the front and rear waistband forming parts 1 and 5 and the crotch part forming part 3 can be knitted in series in the wale direction, the shorts cloth A provided with the predetermined forming parts 1 to 5 by performing the stitch adjustment. Can be easily and continuously manufactured in the wale direction. Although the shorts dough A is in the form of a medium constriction, the shorts composite dough A 'is formed by alternately connecting the connecting doughs 10 and the connecting doughs 10' in the wale direction alternately as shown in FIG. Since the knitting is performed, the shorts dough A can be manufactured with substantially no waste only by generating an unnecessary portion C. Further, these two C portions may be sewn or bonded at their crotch forming portions to obtain another shorts fabric.

In the shorts obtained by the manufacturing method of the present invention, if a bulging portion is provided in the abutting portion of the short portion by heat setting using a mold or the like, a more preferable wearing feeling is exhibited. Further, the knitting method itself by the warp knitting machine may be performed according to a known method so as to correspond to knitting of the shorts cloth targeted in the present invention.

〔The invention's effect〕

According to the method for manufacturing shorts of the present invention, a shorts composite fabric in which a plurality of shorts of a predetermined form are vertically and horizontally combined by a warp knitting machine can be continuously manufactured, and the resulting shorts composite fabric is cut into each shorts fabric. Since it is only necessary to fold and sew the shorts cloth in half, a large amount of shorts can be easily manufactured, and at that time, there is substantially no waste of the cloth, and the shorts obtained are obtained from a single piece of shorts cloth. Despite being made, it has a good feeling of wearing.
