일반적으로 신발, 가방, 지갑 또는 각종 파우치와 같은 제품들은 시대적 유행에 따르는 패션 감각을 갖는 제품들로써, 직물 또는 합성수지 원단의 본체에 각종 부품 또는 장식품을 봉제에 의해 부착하게 된다. In general, products such as shoes, bags, purses or various pouches are products having a fashion sense according to the trend of the times, and various parts or ornaments are attached to the main body of the fabric or the synthetic resin fabric by sewing.
상기 제품들 중 신발의 제조과정을 예로 들면, 도 1에 도시된 바와 같이, 신발 갑피 원단(1)의 외부에 선포(vamp)(3)와 뒷일자 보강(back stay)(2)을 덧대어 봉제한 다음, 그 외부에 앞일자 보강(fore stay)(4)을 덧대어 봉제한 후, 앞보강(toe cap)(5)을 덧대어 봉제하고, 그리고 최종적으로, 앞보강(5)의 외부에 접착제를 이용하여 다양한 형상의 장식물(6)을 접착시키는 과정을 거쳐 통상적인 신발이 제조되며, 가방이나 지갑과 같은 제품들의 경우에도 상기 신발의 제조과정과 같은 공정을 거쳐 제조된다.Taking the manufacturing process of the shoes among the above products, for example, as shown in Figure 1, by applying a vamp (3) and back stay (2) to the outside of the shoe upper fabric (1) After sewing, the front stay reinforcement (fore stay) (4) on the outside, and then sewn with a toe cap (5), and finally, the outside of the front reinforcement (5) The conventional shoe is manufactured through the process of adhering the ornaments 6 of various shapes using an adhesive. In the case of products such as bags and wallets, the shoes are manufactured through the same process as the manufacturing process of the shoe.
하지만 상기와 같은 부착방법은 복잡한 단계의 봉제 공정을 거쳐 신발의 갑피 부분에 복잡한 형태의 봉제선들이 형성됨으로써, 장기간 신발을 신을 경우에는 봉제선이나 또는 봉제선의 틈 사이에 흙, 먼지 등이 끼여 검게 변색되어 고가의 신발이 훼손되어 패션성이 떨어지는 문제점이 발생할 뿐만 아니라 특히 제조과정에서도 다수의 봉제단계를 거침에 따라 봉제선에 의한 불량률이 매우 높아 생산성을 저하시키는 문제점이 있었다.However, the attachment method as described above is a complex sewing seams are formed in the upper portion of the shoe through a complex sewing process, when the shoes are worn for a long time, the seams or dirt between the seams or the gap of the seams become black and discolored In addition to the problem that the expensive shoes are damaged and the fashion is inferior, in particular, the manufacturing process has a problem of lowering the productivity due to the high failure rate due to a plurality of sewing steps.
따라서, 최근들어 원단과 각종 부품 또는 장식품 사이에 폴리우레탄 등의 합성수지로 이루어진 핫멜트 필름을 적층하고, 이를 가열,가압하여 무봉제로 접착시키는 기술이 개발되고 있으며, 관련 선행기술로써, 대한민국 공개실용신안공보 제20-2012-0002543호, 대한민국 특허등록공보 제10-0750612호 및 대한민국 특허등록공보 제10-0835612호 등이 있다.Therefore, recently, a technology for laminating a hot melt film made of a synthetic resin such as polyurethane between a fabric and various parts or ornaments, and heating and pressing the adhesive to a non-sewing adhesive has been developed. As a related prior art, the Republic of Korea Utility Model Publication No. 20-2012-0002543, Republic of Korea Patent Registration No. 10-0750612 and Republic of Korea Patent Registration Publication No. 10-0835612.
하지만, 상기와 같은 종래의 기술은 원단과 각종 부품 또는 장식품의 부착면 전체에 걸쳐 핫멜트 필름이 형성됨에 따라 원단의 통풍, 방습 등의 기능이 저하될 뿐만 아니라, 특히, 원단의 유연성을 현저하게 저하시키는 문제점이 있었다.However, the conventional technology as described above, as the hot-melt film is formed over the entire surface of the fabric and the various parts or ornaments, not only the function of ventilation, moisture proof, etc. of the fabric is lowered, but also, in particular, the flexibility of the fabric is significantly reduced. There was a problem letting.
따라서, 상기와 같은 문제점을 해결하기 위해 대한민국 공개특허공보 제10-2001-0076027호에서는 도 2에 도시된 바와 같은 일정한 규격으로 구멍(12)을 가진 롤러(14)를 이용하여, 도 3에 도시된 바와 같이 열 경화성 자기가교형 접착제 수지(32)를 점(dot) 형태로 원단(20)에 코팅하는 단계를 거친 후, 각종 부품을 합포함으로써, 원단에 우수한 투습도와 부드러운 촉감을 부여한 기술이 공개되어 있다.Therefore, in order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2001-0076027 uses a roller 14 having a hole 12 to a predetermined standard as shown in FIG. As described above, after the step of coating the thermosetting self-crosslinking adhesive resin 32 to the fabric 20 in the form of a dot (dot), by combining various parts, a technique that gives excellent fabric permeability and soft touch is disclosed It is.
하지만, 상기와 같은 종래의 기술은 상기 롤러의 구멍에 충전되는 접착제 수지가 원단 측으로 모두 전이되지 않고 잔류하는 현상이 빈번하게 발생하여 접착제의 양이 일정하게 전이되지 않음에 따라 원단 제품의 접착상태 불량 등의 불량률을 증가시키는 등 생산효율을 저하시키는 원인이 될 뿐만 아니라 상기 롤러의 수명을 단축시키게 되는 문제점이 있었다.However, the prior art as described above is a phenomenon that the adhesive resin filled in the hole of the roller does not all transition to the fabric side, the phenomenon occurs frequently, so that the amount of adhesive is not constantly transferred, poor adhesion state of the fabric product There is a problem that not only causes a decrease in the production efficiency, such as increasing the defective rate of the back, but also shortens the life of the roller.
