The present invention is a method of making a laminated fabric 1 having a first fabric 10 and a second fabric 20, as shown in FIGS. 1-3.

The first laminated fabric manufacturing method of the present invention includes a first adhesive sheet preparation step of preparing a first adhesive sheet 100 including a first hot melt adhesive layer 110 and a second hot melt adhesive layer 220, and a unit a second adhesive sheet preparation step of preparing a second adhesive sheet 200 having a hot-melt adhesive adhesion area per unit area larger than that of the first adhesive sheet 100; 100 first hot melt adhesive layer 110 is placed and a second hot melt adhesive layer 220 of a second adhesive sheet 200 is placed on one side of the first fabric 10 in an area different from the predetermined area. a through-hole forming step of forming through-holes 30 in the first fabric 10 and the second adhesive sheet 200 in the region where the second adhesive sheet 200 exists; and a second fabric bonding step of bonding one side of the second fabric 20 to the hot melt adhesive layer 220 .

As shown in FIGS. 1 to 3, the laminated fabric 1 is a fabric in which a first fabric 10 and a second fabric 20 are laminated. The laminated fabric 1 is preferably a fabric that constitutes clothing. In the present invention, clothing refers to what is worn, and includes upper garments such as hoodies, sweatshirts, coats, jackets, and jumpers, lower garments such as trousers and skirts, and coveralls in which upper and lower garments such as dresses and coveralls are integrated. include. In addition, clothes in the present invention include swimwear, underwear, and the like. Garments containing the laminated fabric 1 can also be used for cold protection, heat protection, sports, and outdoor use.

Examples of fibers forming the first fabric 10 and the second fabric 20 include synthetic fibers such as nylon, polyurethane, and polyester, and natural fibers such as cotton, hemp, wool, and silk. Examples of the material that constitutes the synthetic resin sheets, which are the first fabric 10 and the second fabric 20, include chloroprene rubber and the like. Among others, the first fabric 10 and the second fabric 20 are preferably knitted or woven fabrics. Since the first fabric 10 and the second fabric 20 are knitted fabrics or woven fabrics, when the laminated fabric 1 having the first fabric 10 and the second fabric 20 constitutes a garment, it is comfortable to wear and excellent in durability. It can be used as clothing.

In the first adhesive sheet preparation step, the first adhesive sheet 100 including the first hot-melt adhesive layer 110 is prepared. In the second adhesive sheet preparation step, the second adhesive sheet 200 including the second hot melt adhesive layer 220 and having a larger hot melt adhesive adhesion area per unit area than the first adhesive sheet 100 is prepared.

The second adhesive sheet 200 has a larger hot-melt adhesive adhesion area per unit area than the first adhesive sheet 100 . In order to make the adhesion area of the hot-melt adhesive per unit area of the second adhesive sheet 200 larger than that of the first adhesive sheet 100, for example, the hot-melt adhesive is arranged in a plane as the second adhesive sheet 200. As the first adhesive sheet 100, the hot-melt adhesive is partially arranged and the hot-melt adhesive is not present in some areas. Although not shown, the first adhesive sheet 100 in which the hot-melt adhesive is partially arranged and has a portion where the hot-melt adhesive does not exist includes, for example, the hot-melt adhesive in a mesh shape, a dot shape, or the like. Examples include those arranged in a grid, stripe, wavy line, or the like.

It is preferable that the first adhesive sheet 100 has a hot-melt adhesive arranged in a mesh pattern, and the second adhesive sheet 200 has a hot-melt adhesive arranged in a plane. The hot-melt adhesive is arranged in a mesh pattern on the first adhesive sheet 100 and in a planar pattern on the second adhesive sheet 200 , so that the first adhesive sheet 100 causes the first adhesive sheet 100 to adhere to the first fabric layer in the laminated fabric 1 . In the part where the 10 and the second fabric 20 are joined, the hot melt adhesive is partially present and partially absent, so that breathability and flexibility can be improved. At the part where the first fabric 10 and the second fabric 20 are joined by the sheet 200, the joining strength between the first fabric 10 and the second fabric 20 is increased, and the first fabric 10 and the second fabric 20 are difficult to separate. can be done. As a result, in the laminated fabric 1, both the bonding strength between the first fabric 10 and the second fabric 20 and the breathability and flexibility of the laminated fabric 1 can be achieved.

The adhesion area of the hot-melt adhesive per unit area of the second adhesive sheet 200 is preferably 1.001 times or more the adhesion area of the hot-melt adhesive per unit area of the first adhesive sheet 100 . It is more preferably 01 times or more, more preferably 1.1 times or more. By setting the lower limit of the ratio of the hot melt adhesive adhesion area per unit area of the second adhesive sheet 200 and the first adhesive sheet 100 to the above range, the first fabric 10 and the first fabric 10 by the second adhesive sheet 200 and the first adhesive sheet 100 The bonding strength between the two fabrics 20 can be increased, and the first fabric 10 and the second fabric 20 are less likely to separate. In addition, the hot-melt adhesive adhesion area per unit area of the second adhesive sheet 200 is preferably 50 times or less, such as 45 times, the hot-melt adhesive adhesion area per unit area of the first adhesive sheet 100. It is more preferably 40 times or less, more preferably 40 times or less. By setting the upper limit of the ratio of the hot-melt adhesive adhesion area per unit area between the second adhesive sheet 200 and the first adhesive sheet 100 to the above range, the first adhesive sheet 100 exists in the laminated fabric 1. It is possible to improve the breathability and flexibility in the part where it is.

The hot-melt adhesives of the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 are, for example, ethylene-vinyl acetate copolymers, polyolefins such as polyethylene and polypropylene, butyl rubber and polyisoprene. containing rubber or polyurethane as a main component. The hot melt adhesive contained in the first hot melt adhesive layer 110 may be different from the hot melt adhesive contained in the second hot melt adhesive layer 220, but is preferably the same. . Since the hot-melt adhesive contained in the first hot-melt adhesive layer 110 is the same as the hot-melt adhesive contained in the second hot-melt adhesive layer 220, when the laminated fabric 1 is manufactured, The conditions of temperature and pressure to be applied for joining the first fabric 10 and the second fabric 20 can be made the same, and the efficiency of manufacturing can be improved.

In order for the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 to join the first fabric 10 and the second fabric 20, it is preferable that they can be joined by heating at 60° C. or higher, and 90° C. or higher. It is more preferable that the bonding can be performed by heating at 120° C. or higher. In addition, in order for the first hot melt adhesive layer 110 and the second hot melt adhesive layer 220 to join the first fabric 10 and the second fabric 20, it is preferable that they can be joined by heating at 190° C. or less. It is more preferable to be able to bond by heating at 140° C. or less, and more preferably to be able to bond by heating at 140° C. or less. Above all, it is particularly preferable that the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 can join the first fabric 10 and the second fabric 20 by heating at 120°C or higher and 140°C or lower. By setting the heating temperature required for the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 for bonding the first fabric 10 and the second fabric 20 to the above range, the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 are Defects such as scorching of the fabric 10 and the second fabric 20 are less likely to occur, and the laminated fabric 1 can be manufactured efficiently.

As shown in FIG. 1 , in the first fabric bonding step, a first hot-melt adhesive layer 110 of a first adhesive sheet 100 is placed in a predetermined region on one side of the first fabric 10 , and the one side of the first fabric 10 is The second hot-melt adhesive layer 220 of the second adhesive sheet 200 is arranged in a region different from the predetermined region of .

That is, in the first fabric bonding step, the first hot melt adhesive layer 110 of the first adhesive sheet 100 and the second hot melt adhesive layer 220 of the second adhesive sheet 200 are attached on one surface of the first fabric 10. , the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 are arranged so as not to overlap each other. The first hot-melt adhesive layer 110 of the first adhesive sheet 100 is arranged in a predetermined region on one side of the first cloth 10, and the second adhesive sheet 200 is arranged in a region different from the predetermined region on the one side of the first cloth 10. By arranging the second hot melt adhesive layer 220, the first hot melt adhesive layer 110 of the first adhesive sheet 100 having a hot melt adhesive adhesion area per unit area smaller than that of the second adhesive sheet 200; The second hot-melt adhesive layer 220 of the second adhesive sheet 200 does not overlap each other. The first hot melt adhesive layer 110 and the second hot melt adhesive layer 220 do not overlap each other, so that the first fabric 10 and the second fabric 20 joined by the second adhesive sheet 200 of the laminated fabric 1 Partial breathability and flexibility can be ensured.

FIG. 1 shows that there is no gap between the first hot melt adhesive layer 110 and the second hot melt adhesive layer 220, but in the first fabric bonding process, the first hot melt adhesive layer There may be a gap between 110 and second hot melt adhesive layer 220 . The gap between the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 makes it difficult for the first hot-melt adhesive layer 110 and the second hot-melt adhesive layer 220 to overlap each other. can be done.

As shown in FIG. 2, in the through-hole forming step, through-holes 30 are formed in the first fabric 10 and the second adhesive sheet 200 in regions where the second adhesive sheet 200 exists.

In other words, the through-hole forming step is performed after the first cloth bonding step, and the predetermined region of the first cloth 10 where the second adhesive sheet 200 is placed on the first cloth 10 in the first cloth bonding step Through holes 30 are formed in the first fabric 10 and the second adhesive sheet 200 in different regions. Since the second adhesive sheet 200 has a larger hot-melt adhesive adhesion area per unit area than the first adhesive sheet 100, the second hot-melt adhesive layer does not adhere even if the through holes 30 are formed in the second adhesive sheet 200. A sufficient area of the hot-melt adhesive at 220 can be secured. Therefore, the bonding strength between the first fabric 10 and the second fabric 20 by the second hot-melt adhesive layer 220 can be increased, and the first fabric 10 and the second fabric 20 are particularly separated around the through-holes 30 . can be made difficult.

In the through-hole forming step, methods for forming the through-holes 30 include laser processing, processing using a knife, processing using a punch, and the like. Above all, it is preferable that the through-hole forming step forms the through-hole 30 by laser processing. By forming the through-holes 30 by laser processing, the through-holes 30 can be quickly and neatly formed in the first fabric 10 and the second adhesive sheet 200, and the laminated fabric 1 can be manufactured efficiently. .

The shape of the through-hole 30 when viewed from above the first fabric 10 is not particularly limited, and may be, for example, a circular shape, an oval shape, a polygonal shape, or a combination thereof.

It is preferable that the number of through-holes 30 formed in the through-hole forming step is plural. By having a plurality of through-holes 30 , physical properties tend to be uniform over the entire area of the first fabric 10 in the laminated fabric 1 that is different from the predetermined area.

When the number of through-holes 30 is plural, the shape of each through-hole 30 viewed from the upper surface of the first fabric 10 may be the same or different. Further, when the number of through-holes 30 is plural, the size of each through-hole 30 in a cross section perpendicular to the thickness direction of the first fabric 10 may be the same or different.

As shown in FIG. 3, one side of the second fabric 20 is bonded to the first hot melt adhesive layer 110 and the second hot melt adhesive layer 220 in the second fabric bonding step.

The second cloth bonding step is performed after the through-hole forming step. By performing the second cloth bonding process after the through hole forming process, as shown in FIG. As a result, the physical properties of the first fabric 10 and the second adhesive sheet 200 can be reduced in a region different from the predetermined region of the laminated fabric 1, and the predetermined region of the laminated fabric 1 and the region different from the predetermined region can be reduced. They can have different physical properties.

FIG. 4 is a schematic cross-sectional view of a through-hole forming step in the first method for manufacturing laminated fabrics according to another embodiment. As shown in FIG. 4, the second adhesive sheet 200 has a release sheet 40 laminated on the second hot-melt adhesive layer 220, and the through-hole forming step is performed by It is preferable to form the through holes 30 by arranging the first cloth 10 on the upper surface and irradiating the laser from the upper surface of the first cloth 10 . Since the second adhesive sheet 200 has the release sheet 40, the second hot-melt adhesive layer 220 is prevented from adhering to unintended objects, and the handling of the second adhesive sheet 200 becomes easy. In addition, it is possible to prevent dust from adhering to the second hot-melt adhesive layer 220 and prevent the bonding strength between the first fabric 10 and the second fabric 20 from being lowered by the second hot-melt adhesive layer 220. effect can be exhibited. Further, in the through-hole forming step, the release sheet 40 is arranged on the lower surface and the first cloth 10 is arranged on the upper surface, and a laser is irradiated from the upper surface of the first cloth 10 to form the through-holes 30, thereby releasing the mold with the laser. It is possible to prevent the sheet 40 from being scorched. Therefore, when the release sheet 40 is scorched, the first fabric 10 becomes dirty and the appearance is poor. It is possible to prevent the deterioration and improve the manufacturing efficiency of the laminated fabric 1 .

As shown in FIG. 4 , the first adhesive sheet 100 preferably has a release sheet 40 laminated on the first hot melt adhesive layer 110 . Since the first adhesive sheet 100 has the release sheet 40, the first hot-melt adhesive layer 110 is less likely to adhere to unintended objects, making the handling of the first adhesive sheet 100 easier. It is possible to prevent the bonding strength from being lowered due to dust or the like adhering to the first hot-melt adhesive layer 110 .

When at least one of the first adhesive sheet 100 and the second adhesive sheet 200 has a release sheet 40, the release sheet 40 is removed after the through-hole forming process and before the second fabric bonding process. It is preferable to have a release sheet removing step to remove the mold. By having a release sheet removing step after the through-hole forming step and before the second fabric bonding step, the release sheet 40 is removed from at least one of the first adhesive sheet 100 and the second adhesive sheet 200, A second fabric 20 can be bonded to the first hot melt adhesive layer 110 and the second hot melt adhesive layer 220 .

After the second fabric bonding step, it is preferable to have a hot pressing step in which the entire laminated fabric 1 is hot pressed. By having the hot press process, heat and pressure are applied to the laminated fabric 1, and the whole laminated fabric 1 becomes familiar. As a result, the bonding strength between the first fabric 10 and the second fabric 20 is increased, and the flexibility of the laminated fabric 1 can be enhanced.

After the first fabric bonding step, through holes 30 are formed in the regions where the second adhesive sheet 200 exists. In other words, the through holes 30 are present in the knee portion of the pants. Therefore, the elongation of the laminated fabric 1 at the knee portion of the pants is improved, and the fabric expands and contracts along with the movement of the wearer's knees, making the pants easy to move. Further, in the jacket shown in FIG. 5, the through holes 30 are present at the underarm portions of the front body and the back body, and at the central portion of the back of the back body. Due to the presence of the through holes 30 in the armpit portions and the central back portion of the jacket, the elongation and breathability of the laminated fabric 1 in the armpit portions and the central back portion are enhanced. Therefore, the fabric expands and contracts according to the movement of the arms of the wearer of the jacket, making it easy to move.In addition, heat from the armpits and the back can be released to the outside, making it more comfortable to wear. Furthermore, since the jacket shown in FIG. 5 has through holes 30 in the ears of the hood, the wearer of the jacket can easily hear external sounds even when the hood is on.
