Description
본 발명은 자동차의 내장재에 적용되는 부직포매트의 제조방법에 관한 것으로, 특히 화학섬유와 천연섬유을 적절히 혼용하여 습기와 냄새의 차단은 물론 우수한 성형성과 강도 및 단열효과를 유지하여 변형성의 최소화와 장기간의 안정적인 사용을 보장하여 제품의 신뢰성을 향상시킬 수 있도록 제공되는 부직포매트의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a non-woven fabric mat applied to the interior of the automobile, in particular, by using a suitable mix of chemical fibers and natural fibers to prevent moisture and odors, as well as to maintain excellent formability and strength and insulation effect to minimize deformation and long-term The present invention relates to a method of manufacturing a nonwoven mat provided to ensure stable use and to improve product reliability.
이른바, 자동차의 도어트림이나 천정 및 바닥 등에는 단열과 흡·차음 및 완충효과와 부드러움을 부여하기 위해 섬유재질의 매트가 내장처리된다.So-called door trims, ceilings and floors of automobiles are fabricated with mats made of fibrous materials to provide insulation, sound absorption, sound insulation, cushioning effects and softness.
이러한 내장재는 성형성이 우수하고, 습윤되지 않으면서도 우수한 단열성을 요구받는데, 종래에는 매트를 구성하는 주 소재로 페놀수지를 함침시킨 것과 폐사·폐섬유 등에 폴리프로필렌 단섬유를 혼용하여 니들펀칭한 부직포를 사용함으로서 위와 같은 요구사항을 전혀 만족하지 못하였다.These interior materials are excellent in formability and are required to have excellent heat insulating properties without being wet. Conventionally, nonwoven fabrics needle-punched by mixing impregnated phenolic resin as the main material of the mat and short polypropylene fibers such as dead sand and waste fiber are used. By using, the above requirements were not satisfied at all.
즉, 종이에 페놀수지를 함침하여 제품이 제조됨으로 습기가 종이에 습윤되기 용이하고 성형 후 주름이 발생되어 외관이 불량함은 물론 강도가 약해 손쉽게 꺾여지는 등 그 형상 유지가 곤란하였다.That is, since the product is manufactured by impregnating phenolic resin on paper, moisture is easily wetted on the paper, wrinkles are generated after molding, and appearance is poor as well as weak in strength, and it is difficult to maintain its shape.
따라서, 제조후 바로 취부하지 아니하면 습기로 인한 변형이 발생할 우려가 매우 높았다.Therefore, there is a high risk of deformation due to moisture if not immediately after installation.
한편, 제조과정에서 함유된 페놀수지 가루는 페놀분진 및 역한냄새를 발생시키게 되어 인체에 유해한 영향을 주며, 경직성으로 가공이 용이하지 못하고 전술한 바와 같이 많은 주름으로 인해 흡음이나 단열효과가 매우 낮다는 문제점을 포함하고 있어, 수입규제의 대상으로 지목받거나 작업기피 현상을 유발하기도 하였다.On the other hand, the phenolic resin powder contained in the manufacturing process generates phenol dust and cold smell, which has a detrimental effect on the human body, which is not easy to process due to its rigidity, and the sound absorption or thermal insulation effect is very low due to many wrinkles as described above. It included problems, which were pointed out as the subject of import regulation or caused work evasion.
때문에, 인체의 유해성분 발생없이 자동차의 내장재로 요구되는 사항을 만족하는 매트가 제공될 수 있도록 각별히 배려되어야 만 한다.Therefore, it must be specially considered to provide a mat that satisfies the requirements of the interior material of the car without generating harmful components of the human body.
따라서, 본 발명은 화학섬유와 천연섬유를 일정 비율로 적절히 혼용처리하여 상호 일체화함으로 높은 강도의 유지와 습윤성을 방지하며, 성형후 주름발생이나 변형의 우려없이 우수한 흡음, 차음 및 단열성능을 보유함과 동시에 사용후 오염물질의 발생없는 폐기처리와 재활용이 가능한 친환경적 성격의 부직포매트를 제공함에 그 안출된 목적이 있다.Therefore, the present invention prevents the maintenance of high strength and wettability by integrating chemical fibers and natural fibers in a proper ratio and integrating them together, and has excellent sound absorption, sound insulation, and heat insulation performance without fear of wrinkles or deformation after molding. At the same time, the aim is to provide an eco-friendly nonwoven mat that can be disposed of and recycled without generating contaminants after use.
상기의 목적을 달성하기 위해 본 발명은 융합용 촉매제로 사용되는 폴리프로필렌(PP) 단섬유 10~20중량부와, 폴리에스테르(PET) 단섬유 20~30중량부 및 저융점 폴리에스테르 단섬유(L/M사) 30~50중량부를 1차 혼용처리한 후 여기에 아마포(FLAX) 및 면(COTTON)으로 이루어진 천연섬유 10~20중량부를 2차 혼용처리하여 제조되는 부직포를 기준으로 그 상/하단에 열 융착 바인더 기능의 핫 멜트(HOT-MELT)와, 니들(NEEDLE)펀치로 교락된 부직포를 배치한 후 상기 핫 멜트 상단에 내장재 원단을 위치시킨 다음 200 ~ 250℃의 열풍 및 로울러 프레스를 2~7m/sec의 속도로 통과시킴으로 혼용된 저융점 폴리에스테르 단섬유가 용해되어 화학섬유와 천연섬유가 결합된 후 냉각과정을 통해 소정의 성형품이 제공될 수 있음을 특징으로 한다.In order to achieve the above object, the present invention provides 10 to 20 parts by weight of polypropylene (PP) short fibers, 20 to 30 parts by weight of polyester (PET) short fibers and low melting point polyester short fibers (used as a catalyst for fusion) L / M company) 30-50 parts by weight of the first mixed treatment, and then 10/20 parts by weight of the natural fiber made of flax and cotton (COTTON) is mixed on the basis of the nonwoven fabric Hot melt (HOT-MELT) and a nonwoven fabric entangled with a needle punch (NEEDLE) punch is placed at the bottom, and then the interior fabric is placed on the top of the hot melt, followed by hot air and roller press at 200 to 250 ° C.
