FIG. 1A is a block diagram showing a process of a sewing method according to the present invention, and FIG. 1B shows an embodiment in which the sewing method according to the present invention is applied.

In the following description, the core tape is shown as an embodiment, but the welding tape can be applied in the same or similar way. However, the welding tape has a difference in that it can be bonded by ultrasonic waves.

1A, a sewing method according to the present invention includes fixing a core tape or a welding tape on a lining and attaching the outer surface of the core tape or hot-pressing to bond the welding tape or the core tape to the outer surface to form a down- . Specifically, the method of sewing down garment according to the present invention includes: a step (P11) of preparing a lining; Attaching a welding tape or a core tape to the prepared lining (P12); (P13) sewing the lining with the welding tape or the core tape; Preparing a cloth (P14); And attaching the outer surface to the welding tape or the core tape by welding or hot pressing (P15).

In the present specification, a seam tape is used in a sense including a welding tape. Seam Tape can be bonded in various ways and welding is one of the bonding methods.

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 as limited to garments such as parka, The present invention is not limited thereto.

In order to apply the method according to the present invention, a lining for the manufacture of clothes such as parka should first be prepared (P11). The parka may be in the form of a padded garment or a waterproofed coat, but may be in any garment or coat form known in the art without limitation. The lining can be any material known in the art, such as nylon or polyester, and can be a waterproof coating. When the lining of the parka is prepared, a welding tape or seam tape can be attached (P12). A seam tape 12 may be affixed to a predetermined area or position of the lining 11 as shown in Figure 1 (b) .

The shim tape 12 may be a hot_melt_adhesive film and may be a film of a material made of, for example, a polyurethane, a polyolefin, a polyester, a nylon, a polyamide, or a combination thereof, But it is not limited thereto.

The shim tape 12 may have a sealing function and may have an adhesive force by applying heat or pressure. On the other hand, the core tape 12 may have an adhesive function on both sides or one side. 1B, the shim tape 12 may be temporarily adhered to the lining 11 and fixed firmly to the lining by, for example, a seam line 13 (P13). The shim tape 12 may be fixed to have a predetermined shape, and for example, the shim tape 12 may be disposed along a curved shape. Alternatively, the shim tape 12 may first be fixed to the lining 11 and sewn, and the adhesive component may be coated on the shim tape 12. The width of the core tape 12 is not particularly limited, but may be, for example, 1 to 50 mm, but the present invention is not limited thereto.

When the core tape 12 and the lining 11 are fixed by the seam line 13, the outer cloth 14 can be prepared (P14). The outer surface 14 may be of the same or similar material as the lining 11 or may be a different material, but is not limited thereto and may be any introduction known in the art.

A certain space may be formed between the core tapes 12a and 12b as shown in FIG. 1B (B), and the constant space may be filled with goose hair, goose hair, or other filling material. The filling material may be filled in the predetermined space before the outer cloth 14 is joined or after the outer cloth 14 is joined. Each of the seam tapes 12a and 12b can be fixed to the lining by the seams 13a and 13b and the cloth 14 can be disposed above the seam tapes 12a and 12b (P14).

When the outer cloth 14 is disposed above the core tapes 12a and 12b (P14), the core tapes 12a and 12b can be adhered to the inside of the outer cloth 14 by a hot pressing process, Lines 15a and 15b may be formed (P15). Between the bonding lines 15a and 15b, a filling material such as down can be filled.

In the present specification, the hot pressing process means that the core tapes 12a and 12b are adhered to the outer surface while simultaneously applying heat and pressure. The hot pressing in this specification includes a welding adhesion as described below. Welding adhesion means, for example, adhesion by ultrasonic waves. However, the lining 11 can also be adhered if necessary. The adhesive lines 15a and 15b may be formed to have a width corresponding to a part of the width of the core tapes 12a and 12b or may be formed to correspond to the entire width of the core tapes 12a and 12b.

For example, a heat of 55 to 150 DEG C may be applied to the hot pressing process, while a pressure of 2.0 to 6 bar or 29 to 87 psi may be applied to the adhesion site. And the hot pressing process can be performed by applying heat and pressure for 5 to 30 hours by the hot pressing machine.

When the hot pressing process is completed (P15), the filling material such as down can be filled in an appropriate manner and the finishing process can proceed.

While the embodiments in which the core tapes 12, 12a, 12b are arranged in a straight line in the illustrated embodiment are shown, the core tapes 12, 12a, 12b can be arranged in various shapes and the present invention is not limited to the illustrated embodiment Do not.

When the bonding lines 15a and 15b are formed by the hot pressing process, the bonding lines 15a and 15b are not filled with the down, so that a cold spot can be formed. Cold spots can reduce the warmth of clothing while at the same time lowering the comfort of the garment. According to the present invention, only a part of the welding tape or the core tape 12, 12a, 12b can be adhered to the cloth 14 to reduce the cold spot.

1C shows an embodiment of a method of bonding a core tape and a surface layer in a sewing method according to the present invention.

1C, when the seam tape 12 is fixed to the lining 11 by the seam 13, the seam tape 12 forms the partial adhesive lines 151 and 152, As shown in Fig. The center portion of the shim tape 12 is fixed to the lining 11 by a seam line 13 and both end portions are attached to the cloth 14 to form a partial adhesive line (Fig. 151 and 152 may be formed. The shim tape 12 can be adhered to the cloth 14 so as to form a curved clearance portion 16 adhered to the cloth 14 in the unfolded state as shown in Fig. The smaller the width D of each of the partial adhesive lines 151 and 152 the smaller the cold spot and the narrower the width between the partial adhesive lines 151 and 152 is, . Therefore, it is advantageous to narrow the widths of the partial adhesive lines 151 and 152 while narrowing the interval between the partial adhesive lines 151 and 152 at the same time. However, since the margin portion 16 can prevent the downward protrusion, at the same time, the warm air layer can be formed, so that the size of the margin portion 16 needs to be appropriately adjusted.

On the other hand, the number of partial adhesive lines 151 and 152 is not limited. For example, the number of partial adhesive lines 151, 152 can be one or more, and can have, for example, a structure in which a plurality of mountains and valleys are formed.

Referring to FIG. 2, the adhesive lines 15 may be arranged in a shape in which the curves intersect with each other to be combined with the outer cloth 14. The lining 11 and the seam line 13 may be formed in a curved shape according to the arrangement of the core tapes. Preferably the shim tapes form at least one closed curve or may be arranged to form at least one intersection point. The formation of the closed curve or the formation of the intersection has the advantage that it is possible to arrange the down or fill material appropriately according to the structure of the garment or parka while preventing the down or fill material from being bundled in one part.

Adhesive lines may be formed in a variety of ways and the present invention is not limited to the embodiments shown.

In the embodiment shown, a shim tape is used to bond the lining and the outer surface, and the shim tape is fixed by lining and sewing and can be fixed by hot pressing with the outer surface. As described above, a Welding Tape may be used as an alternative to the shim tape. When a welding tape is used, the welding tape can be fixed by sewing on a down back. And the welding tape may be attached to the outer surface in a structure identical or similar to that of the core tape adhered to the outer surface. For example, the welding tape can be attached to the outer surface by ultrasonic waves. Welding tapes are advantageous in forming curves as compared to core tapes, and thus, various shapes can be easily produced. Also, by attaching the welding tape to the lining by sewing, the welding tape is prevented from being separated from the lining and the downward protrusion is prevented.

The sewing method according to the present invention is advantageous in that it is possible to form a boundary surface for preventing the bunching or bunching of the down, thereby enabling an appropriate down distribution according to the shape of the clothes. In addition, the sewing method according to the present invention has an advantage that the distribution of down is uniform by forming various types of curved surfaces, for example. Also, the method according to the present invention has the advantage that the downward protrusion can be prevented in spite of long-term use. Further, the sewing method according to the present invention reduces cold spots caused by adhesion of the core tape to the outer surface in the down filling process. And it has an advantage that the warmth can be improved by this.
