The waist band portion 100 is manufactured in a band form by connecting at least one of both ends, as shown in FIGS. 1 to 4. At this time, the waist band portion 100 is manufactured to a width sufficient to cover the abdomen along with the waist, and when the leggings according to the present invention are worn, the waist band portion 100 presses the waist and the abdomen at the same time to form the body. It is desirable to configure the correction effect to be enhanced.

At this time, the waist band portion 100, as shown in [Fig. 2], the both ends of the waist band portion 100 are thermally treated and attached integrally without seam (Margin to seam), followed by thermal fusion of the reinforcing band 110 And integrally formed.

One. Thermal knife  process

Thermal knife treatment, as shown in [Fig. 2], the edges of the waist band portion 100, while the edges are in contact with each other while cutting the edge portion while applying heat with a thermal knife (C), the edge is folded into the seam (Margin to Seam ) Does not occur and refers to a technique in which both edges of the waist band portion 100 can be integrally attached as if it were a single material. The thermal knife treatment uses a conventional technique of joining two fabrics or vinyls, such as a heat cutter or a heat sealer, and joining them together by cutting them.

On the other hand, in the present invention, when performing such a thermal knife treatment, both edges of the waist band portion 100 are overlapped and thermally treated as shown in [FIG. 2], so that both edges are formed as shown in [FIG. 2 (b)]. It is desirable to be able to heat-treat as if it is a single fabric.

If the waist band portion 100 is made of a band shape, the thermal knife treatment may be performed only once on both edges, but when the waist band portion 100 is made of a plurality of pieces, neighboring pieces are repeatedly formed into one band shape. It is manufactured in a band form by thermal knife treatment.

2. Column reinforcement Fusion

As shown in FIG. 2 (c), the reinforcing band 110 is heat-sealed to the joining portion of the waist band portion 100 treated with the thermal knife. Here, the reinforcing band 110 is attached so that both edges of the waist band portion 100 are superimposed on the line formed by attaching them as if they were one as they are thermally cut.

At this time, the reinforcing band 110 may be made of the same material as the waist band portion 100, but any material can be used as long as it can support the thermally treated edge line portion so as not to be easily torn or torn. have.

In addition, the reinforcing band 110 may be attached using an adhesive used for clothing, but most preferably, a hot melt is used. Here, the hot melt refers to a thermoplastic resin that melts when heated and solidifies when cooled, and is produced by a conventional technique used for adhesives or coatings.

These hot melts can be placed on the reinforcing band 110 and then welded by applying weak heat, and then the reinforcing band 110 can be placed on the above-described hot-knife-treated portion and then combined by being fused integrally by applying high heat. Of course, the hot melt may be integrally heat-sealed by inserting a hot melt in the form of a film between the reinforcing band 110 and the thermal knife treatment. In addition to this, anyone who is a person in the technical field to which the present invention belongs may find that the hot melt can be heat-sealed in various ways, such as by placing the pre-heated part in advance on a heat-treated part and then welding it, then placing the reinforcement band 110 thereon and heat-sealing it. Anyone will know easily.

On the other hand, the leg insertion portion 200, the edge portion facing each other to insert the leg, or the portion connected to the above-described waist band portion 100, the adjacent edge of each other by overlapping each other thermally treated by seam seam (Margin to seam) and then integrally formed by heat-sealing the reinforcing band 110. Since this thermal knife treatment and heat-sealing have already been described in the above-described waistband portion 100, the detailed description thereof is omitted here. do.

In addition, the leg insertion portion 200, as shown in [Fig. 1] and [Fig. 5], heat-sealing a separate reinforcing band 210 at the inner edge of the end portion. Here, the reinforcing band 210 is to prevent the end portion of the leg insertion portion 200 from being curled or coiled, and also to increase the design aesthetics by preventing the end portion from being blunt. And the heat fusion method at this time is made in the same manner as the method described in the waist band portion 100 described above.

Finally, the leg insertion portion 200 is configured by adding a hip-up portion 220, as shown in [Fig. 1], [Fig. 3], and [Fig. 4]. The hip-up portion 220 starts from the front upper portion of the inguinal part (the upper portion of the thigh front) when the leggings according to the present invention are worn, and is formed to cross the hip portion along the panty line. At this time, it is preferable that the hip-up portion 220 is configured to be able to obtain a body shape correction effect with the above-described compression band 120 by supporting the hip muscle upward while becoming a "V" shape as a whole.

As described above, the present invention adopts a non-sewing method, but is thermally processed to adhere integrally without seam (Margin to seam), and then heat-sealed with a reinforcing band, so as to be integrally manufactured, even if the structure is complicated, it can be easily and quickly manufactured to increase productivity Can be increased. In addition, the compression effect of the waist and abdomen through the crimping band and the hips are supported through the hip-up part, so that the body is supported while supporting the waist, and the end of the leg insertion part is reinforced with a reinforcement band to dry or easily The quality can be improved by not folding.

On the other hand, the present invention can be easily understood by anyone skilled in the art to which the present invention pertains to be able to enhance the aesthetic sense by decorating the edge of the waist band portion or the edge of the leg insertion portion.
