본 발명은 자동차 도어트림용 부직포의 제조 방법에 관한 것으로서, 보다 상세하게는 부직포와 다른 중첩물과의 접착 방법을 개선함으로써 자동차 도어트림의 제조를 보다 용이하게 한 자동차 도어트림용 부직포의 제조 방법에 관한 것이다.The present invention relates to a method for manufacturing a nonwoven fabric for automobile door trim, and more particularly, to a method for manufacturing a nonwoven fabric for automobile door trim, which makes it easier to manufacture an automobile door trim by improving a bonding method between a non- .
자동차 내부에는 여러 가지 내장재가 쓰이는데, 예를 들면, 도어 트림(Door trim), 헤드 라이너, 리어 셸프, 트렁크 매트, 카매트 등이 그것이다. 이들은 대체로 자류, 비닐, 섬유 직ㆍ편물, 부직포, 합판 또는 연질 목재 압착물 등의 조합으로 이루어진 중첩물로 되어 있다.Various interior materials are used in the interior of the vehicle, such as door trim, head liner, rear shelf, trunk mat and car mat. They are usually made up of a combination of self-extinguishing, vinyl, fiber knitted or woven, non-woven, plywood or soft wood pressed.
이들 자동차 내장재는 차량 내부를 보다 안락하게 보이도록 장식할 뿐만 아니라, 차음, 흡음 및 충격완화를 위한 쿠션 역할을 한다. 이러한 자동차 내장재가 갖추어야 할 기능으로서는 미려한 외관을 지녀야 하고, 보온 단열성, 차음성, 흡음성 및 쿠션이 좋아야 하며, 또한 차량의 무게를 줄이기 위하여 경량이어야 할 뿐만 아니라, 차량의 복잡한 내부 구조 및 차종에 따른 구조 변화에 잘 적응하여 성형될 수 있어야 하므로 성형성이 좋아야 한다.These automotive interiors not only decorate the interior of the vehicle to make it look more comfortable, but also act as a cushion for sound insulation, sound absorption and shock reduction. Such automobile interior materials should have a beautiful appearance and should have good thermal insulation, sound insulation, sound absorbing property and cushion, and should be lightweight in order to reduce the weight of the vehicle. In addition, the interior structure of the vehicle and the structure The moldability should be good because it must be able to adapt to the change and be molded.
자동차 내장재중 도어 트림(Door trim)은 자동차 도어의 내부 하단에 소용되는 내장재로서 상술한 바와 같은 역할과 기능을 만족시키도록 제조되며, 제1도는 통상적인 일예로서 도어 트림의 단면 층구조를, 제2도와 제3도는 대체적인 외형 구조 및 차량내 위치를 보여주고 있다.A door trim of an automobile interior material is manufactured to satisfy the roles and functions as described above as an interior material used in the interior lower part of an automobile door. The first figure shows a conventional door trim structure, Figure 2 and Figure 3 show the alternative topography and location in the vehicle.
제1도 및 제2도를 참조하면 통상의 도어 트림(1)은 단면이 3층 구조로서 상층(표면층)(2)은 PVC 시트, 중간층(3)은 부직포 또는 우레탄폼, 하층(도어의 내벽과 접착되는 층)(4)은 합판 또는 목재 부스러기를 압착하여 만들어지는 칩보드로 이루어져 있다.1 and 2, the conventional door trim 1 has a three-layered structure in which the upper layer (surface layer) 2 is a PVC sheet, the intermediate layer 3 is a nonwoven fabric or a urethane foam, (4) is composed of a chip board made by pressing a plywood or wood shavings.
이와 같은 도어 트림의 제조는 중간층(3)이 부직포로 이루어지는 경우에 부직포 제조업자가 적정 규격의 부직포를 제조하여 도어 트림 제조업자에게 인도하면 도어 트림 제조업자는 상기 부직포의 양면에 접착제인 본드를 분사하는 본드 스프레이 공정을 거친 후 건조시킨 다음, 상, 하층(2,4)에 PVC 시트 및 칩 보드를 적층하여 제2도와 같은 최종 성형구조를 갖는 금형을 갖춘 프레스에 의해 최종 모양으로 고주파 절단하면서 압착, 부착함으로써 이루어진다.When the intermediate layer 3 is formed of a nonwoven fabric, the manufacturer of the nonwoven fabric manufactures the nonwoven fabric of an appropriate standard and delivers the nonwoven fabric to the door trim maker. The door trim maker attaches a bond After spraying and drying, the PVC sheet and the chip board are laminated on the upper and lower layers (2, 4), and then subjected to high frequency cutting in a final shape by a press having a mold having a final molding structure such as the second drawing, .
그러나, 이와 같은 종래의 도어 트림의 제조 방법에 있어서는 본드 스프레이 공정에서 인체에 유해한 본드 냄새가 심하게 나고 또한 상당한 시간을 요하는 건조 단계를 거쳐야 하므로 공정 지연을 초래하는 단점이 있었다.However, in the conventional method for manufacturing the door trim, there is a disadvantage that the bond smell badly harmful to the human body in the bond spraying process is severe and the drying step requiring a considerable time is required.
본 발명의 목적은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로서 특별한 부직포와 바인더의 조합을 채용하여 도어트림의 제조 과정에서 본드 스프레이 공정을 생략할 수 있게 한 자동차 도어트림용 부직포 및 그를 이용한 자동차 도어트림의 제조 방법을 제공함에 있다.It is an object of the present invention to solve the problems of the prior art as described above, and it is an object of the present invention to provide a nonwoven fabric for automobile door trim, which can eliminate the bond spraying process in the process of manufacturing door trim, And a method for manufacturing a door trim.
본 발명의 자동차 도어 트림용 부직포는 저융점을 가진 PVC계 단섬유 또는 폴리프로필렌 단섬유와 폴리에스테르 단섬유가 중량비로 10 : 90 내지 50 : 50으로 혼합된 열융착 니들펀치 부직포의 양면에 PVC 또는 PVDC계 수성 바인더를 스프레이하여 제조되는 것이 특징이다.The automotive door trim nonwoven fabric of the present invention is characterized in that a PVC-based short-staple fiber or polypropylene staple fiber having a low melting point and a polyester staple fiber are mixed in a weight ratio of 10: 90 to 50:50, And a PVDC-based aqueous binder.
또한, 본 발명의 상기 부직포를 이용한 자동차 도어 트림의 제조 방법은 상기 본 발명의 부직포의 상하층에 PVC 시트 및 칩보드 등의 통상의 중첩물을 중첩시킨 다음 소정의 고온 금형 프레스에 의해 고주파 절단하면서 중첩물을 압착 및 부착하여 이루어진다.Further, in the method for manufacturing the automobile door trim using the nonwoven fabric of the present invention, normal overlays such as a PVC sheet and a chip board are superimposed on upper and lower layers of the nonwoven fabric of the present invention, and then high frequency cutting is performed by a predetermined high temperature mold press And pressing and adhering the overlay.
상기 부직포 소재중 폴리에스테르는 그 대신에 또는 혼합되어 나이론, 폴리프로필렌, 폴리에틸렌 등의 화학섬유가 사용될 수 있다는 것은 당업자에게는 명백한 것이다. 또한 상기 PVC계 섬유 대신에 다른 저융점 화학섬유를 사용하는 것도 가능하다.It will be apparent to those skilled in the art that among the nonwoven fabrics, polyester may be used instead of or in admixture with chemical fibers such as nylon, polypropylene, and polyethylene. It is also possible to use other low melting point chemical fibers in place of the above PVC-based fibers.
본 발명의 부직포중 혼합되는 PVC계 섬유는 저융점을 가짐으로써 부직포 제조공정중 열융착용 고온 고압 로울러를 통과하면서 약 150 내지 200℃의 온도에서 부분용융되어 폴리에스테르 섬유와 융착 결합되며, 도어트림 제조 공정에서는 상층의 PVC 시트와 동종의 고분자이므로 서로 잘 부착되는 이점을 가지고 있다.The PVC-based fibers mixed in the nonwoven fabric of the present invention have a low melting point and are partially melted at a temperature of about 150 to 200 캜 while being passed through the heat-resistant high-temperature high-pressure roller during the nonwoven fabric manufacturing process to fuse with the polyester fiber, In the process, since it is the same kind of polymer as the PVC sheet in the upper layer, it has an advantage of being adhered to each other well.
상기 PVC 또는 PVDC계 수성 바인더는 분말상으로 접착시 악취가 없고 접착공정후 특별히 건조시킬 필요가 없다. 따라서, 도어 트림 제조업자로서는 본 발명의 부직포를 채용하면 악취가 나며, 장시간의 건조 공정을 요하는 본드 스프레이 공정을 생략할 수 있게 된다.The PVC or PVDC-based aqueous binder is odorless when adhering in powder form and does not need to be particularly dried after the bonding process. Therefore, when the nonwoven fabric of the present invention is used as a door trim maker, odor is generated and a bond spraying process requiring a long drying process can be omitted.
본 명세서에서 특별히 언급 및 설명되지 않은 부직포 제조공정은 통상의 공정에 따르는 것이며, 그와 같은 공정들은 당업계에서 통상의 지식을 가진 자라면 쉽게 알 수 있을 것이다.The nonwoven fabric manufacturing process not specifically mentioned and described herein is subject to conventional processes, and such processes will be readily apparent to those skilled in the art.
상술한 바와 같이 본 발명에 따르면 자동차 도어트림의 제조에 있어서 본드 스프레이 공정을 생략할 수 있어서 공정중의 악취를 없앨 수 있고 공정 시간을 단축시킬 수 있는 자동차 도어 트림용 부직포가 제공되는 효과가 있다.As described above, according to the present invention, it is possible to omit the bond spraying process in the manufacture of automobile door trim, thereby eliminating odors during the process and shortening the process time.
이상에서 본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 기술 사상 범위내에서 다양한 변형 및 수정이 있을 수 있음은 해당 분야에서 통상의 기술을 가진 자에게는 명백한 것이며 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It goes without saying that it falls within the scope of the claims.
