Abstract
Description
본 발명은 가죽의 상품성 및 쿠션성 향상을 위하여 가죽의 뒷면에 스펀지를 연속적으로 접착시킬 수 있도록 한 가죽과 스펀지의 라미네이팅 제조 방법에 관한 것이다.The present invention relates to a method for producing a laminating of the leather and the sponge to continuously adhere the sponge to the back of the leather in order to improve the merchandise and cushioning properties of the leather.
일반적으로 라미네이팅(Laminating)이란 접착수지와 열을 이용하여 원재료와 부재료를 접착하는 공법을 말하며 가죽 뒷면에 스펀지를 라미네이팅 접착시키는 방법에는 두 가지가 있다.In general, laminating refers to a method of bonding raw materials and subsidiary materials using adhesive resin and heat. There are two methods of laminating a sponge on the back of leather.
첫 번째는 핫 멜트 공법으로 공개번호 특1996-0017143에서와 같이 핫 멜트 접착제를 스펀지에 도포하여 건조한 후 재단된 가죽과 함께 가열로 내에서 가압하여 접착한다. The first is a hot melt method, which is applied as a hot melt adhesive to a sponge as in Publication No. 1996-0017143, dried, and then pressurized together with the cut leather in a heating furnace.
상기 핫 멜트 공법은 핫 멜트 접착제 특성상 140-180℃ 조건에서 20-30초 동안 가압을 하여야 하는데 이러한 고온의 가압 조건에 의해 가죽이 경화되어 강연도가 불량하게 되므로 상품성이 크게 저하되어 극히 일부 부분에만 제한적으로 적용되고 있다. The hot melt method should be pressurized for 20-30 seconds at 140-180 ° C. due to the characteristics of the hot melt adhesive. As the leather is hardened by the high temperature pressurized condition and the stiffness is poor, the merchandise is greatly deteriorated and only a part of the melt is poor. Limited application.
또한, 핫 멜트용 접착제 도포 및 건조, 가열, 가압 등 복잡한 공정으로 인하여 생산성이 저하되고 비용이 증가하는 단점이 있다. In addition, there is a disadvantage that the productivity is lowered and the cost is increased due to a complex process such as hot melt adhesive coating and drying, heating, pressurization.
두 번째는 등록신안실용 제20-0346633호와 같이 불꽃 라미네이팅 공법으로 스펀지의 표면을 가스 불꽃으로 녹이면 액상의 점착제가 되고 직물이나 인조가죽 뒷면에 붙여 한 쌍의 롤러로 가압하면 스펀지가 접착하게 되는데, 통상 가죽은 원소재의 수율 향상을 위해 피혁회사에서 각 형상 별로 재단한 다음에야 스펀지와 접착하는 라미네이팅 처리를 해야 한다. The second is flame laminating method like registration model room 2-2-346633. When the surface of sponge is melted by gas flame, it becomes liquid adhesive and when it is pressed with a pair of rollers, it is attached to the back of fabric or artificial leather. Normally, leather must be laminated to the sponge only after it has been cut by the leather company to improve the yield of raw materials.
그러나 롤 상태의 스펀지에 재단된 가죽만 선택적으로 부착시킬 수 있는 방법이 없으며, 스펀지 일면을 녹이면 가죽이 없는 부분에서는 녹은 스펀지가 롤러에 부착되어 연속적인 생산을 할 수가 없게 된다. However, there is no way to selectively attach only the cut leather to the rolled sponge, and if one side of the sponge is melted, the melted sponge is attached to the roller in the non-leather portion, and thus continuous production is not possible.
따라서, 부득이 가죽과 동일한 형상으로 재단된 스펀지를 겹쳐 놓고 가장자리만 재봉을 하여 부착하므로 하중을 가한 후 제거하면 가죽과 스펀지의 신율 및 복원율 상이에 따라 서로 이격되고 이로 인하여 주름 발생 및 표피 부상 등의 품질 문제가 발생되고 있다.Therefore, it is unavoidable that the sponges cut into the same shape as leather are overlapped and only the edges are sewn and attached. Problems are occurring.
본 발명은 이와 같은 종래의 결점을 해결하기 위한 것으로, 본 발명의 목적은, 스펀지의 일측 표면을 녹여서 가죽 뒷면에 부착시키되, 상온에서 처리함으로써 고온의 가압 조건에서 발생되는 가죽의 경화를 막아 부드러움을 유지하도록 하고 연속적인 작업을 통해 생산성을 향상시킬 수 있도록 하는 가죽과 스펀지의 라미네이팅 제조 방법을 제공하는데 있다.The present invention is to solve such a conventional drawback, the object of the present invention is to melt the surface of one side of the sponge attached to the back of the leather, by treating at room temperature to prevent the hardening of the leather generated under high pressure conditions to soften It is to provide a laminating method of leather and sponge that can be maintained and improved in productivity through continuous operation.
이와 같은 목적을 달성하기 위한 본 발명은, 수평 컨베이어 벨트 또는 테이블위에 이형지를 깔고 이형지 위에 각기 다른 형태로 재단된 가죽을 배치하여 연속적으로 이송되게 하고, 다른 한편으로는 스펀지의 일측 표면에 열을 가해 녹인 후 가죽위로 공급하는 동시에 한 쌍의 롤러로 가압하여 가죽 뒷면에 스펀지를 접착시킴으로써 달성할 수 있다.In order to achieve the above object, the present invention lays out a release paper on a horizontal conveyor belt or a table, arranges the cut leather in different shapes on the release paper, and continuously transfers the heat to one surface of the sponge. This can be achieved by adhering the sponge to the back of the leather by melting and feeding it onto the leather and simultaneously pressing it with a pair of rollers.
이상과 같은 본 발명은 직물 또는 인조가죽과 스펀지의 라미네이팅 공정처럼 스펀지를 가죽 뒷면에 연속적으로 라미네이팅 처리하도록 함으로써 현재의 고질적인 품질 불량인 주름 발생 및 표피 부상 등을 근본적으로 해결하여 가죽의 상품성을 향상시키고, 자동차용 시트, 가정용 및 사무용 가죽 소파나 의자, 의료기기용 의자 등 설비, 가방, 핸드백, 신발, 의복 등 가죽을 적용하는 전 분야에 파급 적용이 가능한 효과가 있다.The present invention as described above, by laminating the sponge on the back of the leather like the laminating process of the fabric or artificial leather and sponge to fundamentally solve the current inferior quality defects such as wrinkles and cuticle injuries improve the merchandise of the leather In addition, there is an effect that can be applied to all areas of applying leather, such as seats, bags, handbags, shoes, clothing, such as seats for automobiles, home and office leather sofas and chairs, medical equipment.

도 4는 본 발명에 의해 각 형상 별로 재단된 가죽 형상을 나타낸 것이다.Figure 4 shows the leather shape cut for each shape by the present invention.
이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.
통상, 롤 상태로 생산된 직물이나 인조가죽(8)은 상품성 및 쿠션성 향상을 위하여 스펀지(3) 표면을 불꽃이나 히터(4)로 녹여 원단인 직물이나 인조가죽 뒷면에 라미네이팅하여 사용한다.In general, the fabric or artificial leather (8) produced in a roll state is used by melting the surface of the sponge (3) with a flame or a heater (4) in order to improve the merchandise and cushioning properties, laminated to the back of the fabric or artificial leather.
이러한 공정은 도 2와 같은 연속공정으로 이루어지나, 가죽의 경우는 원소재의 수율 향상을 위해 도 3, 도 4와 같이 피혁회사에서 각 형상 별로 재단한 다음에 스펀지(3)과 접착하는 라미네이팅 처리를 하게 된다. This process is made of a continuous process as shown in Figure 2, but in the case of leather lamination treatment bonded to the sponge (3) after cutting for each shape as shown in Figure 3, 4 in order to improve the yield of raw materials Will be
그런데 롤 상태의 스펀지(3)에 도 4와 같이 재단된 가죽만 선택적으로 부착시킬 수 있는 연속 제조방법이 아직까지는 제안된 것이 없다.By the way, a continuous manufacturing method for selectively attaching only the cut leather to the
또한, 불꽃이나 히터(4)로 표면을 녹임으로써 점착성이 생긴 스펀지(3)를 가죽(5)의 뒷면에 접착함과 동시에 가죽(5)이 없는 부분에서는 롤러 또는 컨베이어 벨트에 스펀지가 고착되어 연속적인 생산을 할 수가 없다. In addition, the
따라서, 본 발명에서는 롤 상태로 생산된 직물이나 인조가죽과 동일하게 가죽과 스펀지를 라미네이팅 할 수 있는 방법을 제공하고자 한다. Accordingly, the present invention is to provide a method for laminating leather and sponge in the same manner as the fabric or artificial leather produced in a roll state.
즉, 도 1과 같이 한 쌍의 롤러(1)(2)에 연속으로 이형지(6)가 공급되도록 하고, 상기 이형지(6) 위에 각기 다른 형태로 재단된 가죽(5)을 뒷면이 상방을 향하게 배치하여 연속적으로 이송되게 하고, 다른 한편으로 스펀지(3)의 일측 표면에 가스 불꽃 또는 히터(4)로 열을 가해 녹인 다음 가죽(5)위로 공급함과 동시에 한 쌍의 롤러(1)(2)로 가압하여 가죽(5)의 뒷면에 스펀지(3)을 접착시킨다. That is, as shown in FIG. 1, the
이때, 가죽이 없는 부분은 이형지(6)에 스펀지(3)가 접착되어 이송되므로 연속작업이 가능하게 된다. At this time, the part without the leather is transported because the sponge (3) is bonded to the release paper (6) to enable continuous operation.
또한, 라미네이팅이 완료되면 도 4와 같은 가죽 테두리를 따라 스펀지(3)와 이형지(6)를 절단하며 가죽 이외의 부분을 폐기하면 본 발명의 목적이 달성된다.In addition, when the laminating is completed, the object of the present invention is achieved by cutting the
