DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

Fig. 1 schematically shows an embodiment of a sewing method according to the present invention. ]

Referring to FIG. 1, a method for sewing a garment fabric according to the present invention comprises the steps of: (P11) preparing a welding tape on which a sewing line has been determined; Determining a downfill space (P12); (P13) determining a seam line to the lining and the outer fabric based on the downfilling space in the weld tape; (P15) sewing the lining and the outer fabric along the seam line (P14) to form a first interface (P15); Forming a second interface at a location opposite the first interface; And forming a downfill space by the first interface and the second interface (P16).

The method according to the present invention can be applied to any production process in which the filling material is filled between the lining and the outer material, such as clothing, mat covers or bedding, and the invention will be described below with reference to garments such as parka, The present invention is not limited thereto.

For application of the method according to the present invention, a welding tape or welding film should be prepared (P11). A seam tape may be prepared as an alternative to a welding tape or a welding film. The welding tape or welding film may be made from, for example, an acrylic material, a nylon polymer, a polyester polymer, a polylactic acid (PLA) polymer, a polyvinyl chloride polymer, or a combination thereof. The core tape can also be, for example, a hot-melt adhesive film and can be a film of a material made of, for example, polyurethane, polyolefin, polyester, nylon, polyamide or a combination thereof. The prepared welding tape or core tape may have a thickness of 30 to 250 mu m and the width may be appropriately selected according to the lining or the surface. Welding tape or shim tape may have a waterproof function or an insulating function and may further have a moisture permeable waterproof function.

When the welding tape or the core tape is prepared (P11), the down space can be determined (P12). The down space means the space where the down is filled and can be determined according to the design of the down garment. The down-space may be determined by the relative distance between the lining and the outer surface to be formed by the down and the distance between the seams on the welding tape, which may have a generally linear shape or a curved shape. The sewing line can be set according to the determined down space (P13).

A sewing line is a line that allows the welding tape to be fixed to the fabric by the lining or sewing with the lining. The setting of the seam line can be determined by whether the adhesion by a method such as hot pressing will be done or by the design of the filling space. The determination of the seam line includes, for example, the distance from the outer edge of the welding tape to the inside. Once the seam line is determined, the sewing can be done accordingly and one edge of the welding tape can be fixed to the outer surface and the other edge to the lining (P14). If necessary, the outer portion of the seam can be adhered to the lining and the outer surface, respectively, by a method such as hot pressing. In such a portion, the down-filled portion of the down space is prevented from escaping to the outside by adhesion, and at the same time, the boundary portion is formed to be double, thereby improving the warmth. The adhesive portion can be, for example, an outer portion of the seam and an inner portion of the seam, with reference to the seam, so that damage to the seam can be prevented by including the seam in the adhesive.

When the sewing or bonding is completed, a first interface can be formed (P15). The first interface may be formed by a welding tape or a cored tape having both edge portions joined to the lining and the outer surface by sewing or bonding. The height of the first interface can be appropriately set in accordance with the width of the welding tape and the position of the seam line.

When the first interface is formed, a second interface may be formed at a position facing the first interface in the same or similar manner as the first interface. A downfill space may be formed by forming the second interface (P16). And a down-filled space formed by the first interface and the second interface can be filled with down. By forming the downfill space by the first interface and the second interface, it is possible to prevent cold spots from being formed, and at the same time the warmth is improved and the seams can be prevented from being damaged.

The following is an explanation of embodiments of the respective processes to which the method according to the present invention is applied.

2A and 2B illustrate an embodiment of a structure in which a lining and a cloth are connected by a welding tape in a sewing method according to the present invention. Fig.

And the two side portions of the welding tape 23 can be fixed to the lining 21 and the cloth 22 on the seam lines 24a and 24b. If the both edges are fixed by the seams 24a and 24b, the edge portions can be adhered to the lining 21 and the surface 22, for example, by hot pressing, if necessary. The adhesive portion can be predetermined and can, for example, be a constant portion about the seam lines 24a, 24b. When the welding tape 23 is fixed to the lining 21 and the surface cloth 22, a first interface is formed.

Referring to FIG. 2B, a plurality of welding tapes 23a, 23b, and 23c may be separately fixed to the lining 21 and the outer surface 22 at regular intervals, and the first, second, . And a downfill space may be formed between the first interface and the second interface, and between the second interface and the third interface. The portions to which the welding tapes 23a, 23b, and 23c are bonded may form a straight line or a curved line and may have the same or different adhesive thickness. The distances between the two different interfaces may be the same or different from each other.

2C is a plan view of the downfilling space formed by the lining 21 and the surface 22 and FIG. 2C is a plan view showing the welding tape 23 fixed to the lining or outer surface In the second embodiment.

Referring to FIG. 2C, the lining 21 and the outer cloth 22 may be separated by the welding tapes 23a and 23b. The seams 27a and 27b of the lining 21 can be formed in consideration of the volume of the downfilling space in each of the welding tapes 23a and 23b. The seams 28a and 28b of the outer cloth 22 may also be formed maintaining a distance apart from each other. As described above, an adhesive surface by hot pressing around the seams 27a, 27b, 28a and 28b can be formed. The size of the seams 27a, 27b, 28a and 28b and the adhesive surface may be predetermined and may be adhered to the lining 21 or the surface 22 by, for example, ultrasonic, microwave, ultraviolet or infrared rays . Alternatively, it can be adhered by pressure or thermal resistance. Adhesion by thermal resistance can be achieved by, for example, arranging conductive leads along the seams 27a, 27b, 28a, 28b. A down filling space can be formed by different welding tapes 23a and 23b.
