Description
본 발명은 촉감성과 쿠션성이 우수하여 쾌적감이 뛰어난 시트용 쿠션재의 제조방법 및 이를 이용한 차량용 시트의 제조방법에 관한 것이다.The present invention relates to a method for producing a cushioning material for a seat, which is excellent in feeling of comfort and cushioning property, and a method for manufacturing a vehicle seat using the same.
일반적으로 부직포는 천연 또는 화학, 재생 등의 각종섬유 소재를 상호간에 일정한 방향성이 없이 엉키게 하여 웹(Web)을 형성한 다음, 이를 화학적, 물리적인 방법으로 결합, 안정화시켜 제조된다. 이러한 부직포는 종이나 천과 같은 형태로 제조되어 산업 자재나 생활주변에서 그 사용목적에 따라 광범위하게 활용되고 있다.Generally, a nonwoven fabric is produced by binding a variety of fiber materials such as natural, chemical, and regenerated yarns to each other without forming a certain direction to form a web, and then bonding and stabilizing the web by chemical and physical methods. Such a nonwoven fabric is manufactured in the form of paper or cloth, and is widely used in industrial materials and living environments according to the purpose of use.
특히, 부직포는 천연피혁이 주로 사용되면서 쿠션감이 요구되는 차량용 시트, 휠체어용 시트, 의자용 시트 등의 소재뿐만 아니라 각종 가방, 의류, 볼, 신발 등의 소재로 활용되고 있다. 또한, 최근에는 환경 친화적이면서 대량생산이 용이한 인조피혁 및 천의 활용도가 높아짐에 따라 인조피혁 또는 천의 소재로도 활용될 수 있도록 품질 및 기능성이 향상된 부직포가 요구되고 있다.In particular, nonwoven fabrics have been used as materials for various kinds of bags, clothes, balls, and shoes as well as materials for automobile seats, wheelchair seats, chair seats, etc. requiring cushioning feeling while natural leather is mainly used. In recent years, there has been a demand for a nonwoven fabric which is improved in quality and functionality so that it can be utilized as a material for artificial leather or cloth, as artificial leather and cloth, which are environmentally friendly and easy to mass-produce, are increased in utilization.
종래 부직포를 제조하는 방법으로는 나일론 단섬유, 일반 폴리에스테르 단섬유 등을 주원료로 사용하여 혼타면, 카딩, 크로스레핑, 니들펀칭, 카렌더 등의 공정에 의해 제조하는 방법과, 나일론 단섬유와 고수축 폴리에스테르 섬유를 혼용하여 혼타면, 카딩, 크로스레핑, 니들펀칭, 수축, 카렌더 등의 공정에 의해 고밀도 부직포를 제조하는 방법이 주종을 이루고 있으나, 이 방법에 의해 제조된 부직포들은 천연피혁, 인조피혁 또는 천의 기능성을 부여하는데 한계가 있었다.Conventional methods for producing the nonwoven fabric include a method of producing nylon staple fibers and general polyester staple fibers by a process such as hornsurface, carding, cross-refining, needle punching, and calendering, Density nonwoven fabric is produced by a process such as kneading, carding, cross-refining, needle punching, shrinking, calendering or the like using mixed shrinkable polyester fibers. However, the nonwoven fabric produced by this method is a natural leather, There was a limit in imparting the functionality of the leather or cloth.
즉, 단섬유만을 니들펀칭하여 제조한 부직포는 설비특성상 단섬유를 물리적 결합에 의해 엉키게하여 제조하는바 섬유의 방향성이 없기 때문에 종, 횡으로 인장력을 가했을 때에 신축 회복율이 작고, 또한 섬유의 반발 탄성이 적기 때문에 쿠션기능도 없어 쿠션 및 신축 회복성 부여에는 한계가 있었다. 또한, 고밀도 부직포의 경우에는 단섬유만으로 제조된 일반 부직포와 비교하여 섬유밀도 및 절단신도는 높지만, 단섬유의 섬도가 가늘고 방향성이 없으며 단섬유만으로 교락되어 있기 때문에 쿠션 및 신축회복성이 아주 약한 문제가 있다.That is, a nonwoven fabric manufactured by needle-punching only short fibers is produced by tangling short fibers by physical bonding due to the characteristics of the apparatus. Since there is no directionality of the fibers, the expansion and contraction recovery rate is small when the tensile force is applied longitudinally and transversely. There is no cushioning function because there is little elasticity, and there is a limit to the cushioning and stretching restorability. In addition, in the case of a high-density nonwoven fabric, the fiber density and the cutting elongation are higher than those of a general nonwoven fabric made of only a single fiber. However, since the fineness of the single fibers is small and the fibers are not directional, .
따라서 부직포의 품질 및 기능성을 향상시켜 천연피혁, 인조피혁, 천 등의 어떠한 표피재에도 적용이 가능하며, 촉감성과 쿠션성이 우수한 쿠션재를 제조할 수 있는 방법이 요구되고 있다. Accordingly, there is a demand for a method for manufacturing a cushioning material which can be applied to any skin material, such as natural leather, artificial leather, cloth, etc., by improving the quality and functionality of the nonwoven fabric.
본 발명의 목적은 촉감성과 쿠션성이 우수하여 쾌적감이 뛰어난 시트용 쿠션재를 제조하는 방법을 제공하는데 있다.An object of the present invention is to provide a method for producing a cushioning material for a seat which is excellent in tactility and cushioning property and excellent in comfort.
또한, 본 발명의 다른 목적은 상기 제조방법에 의해 제조된 시트용 쿠션을 이용하여 차량용 시트의 제조방법을 제공하는데 있다.Another object of the present invention is to provide a method for manufacturing a vehicle seat using the cushion for a seat manufactured by the above-described manufacturing method.

Further, when the polyamide web is used, strength and elongation at break of the cushioning material of the present invention can be further improved.
이러한 폴리아미드 웹의 밀도는 50 내지 300 g/m2, 바람직하게는 80 내지 200 g/m2이다. 폴리아미드 웹의 밀도가 상기 하한치 미만인 경우에는 쿠션재와 표피재가 단단하게 접착되지 않을 수 있으며, 상기 상한치 초과인 경우에는 통기저항 및 촉감이 저하될 수 있다.The density of such a polyamide web is 50 to 300 g / m 2 , preferably 80 to 200 g / m 2 . If the density of the polyamide web is less than the lower limit value, the cushioning material and the skin material may not be firmly adhered to each other.

본 발명에 따라 시트용 쿠션재를 제조하는 방법은 도 1에 나타낸 바와 같이, 먼저 실리콘 섬유(110)를 포개어 놓고 니들펀칭 공정을 통해 필요한 두께의 실리콘 섬유 부직포(120)를 형성한다.1, a method of manufacturing a cushioning material for a seat according to the present invention includes first forming a silicon fiber
다음으로, 상기 형성된 실리콘 섬유 부직포(120)의 일면에 폴리아미드 웹(130)을 구비한 후 실리콘 섬유 부직포와 폴리아미드 웹을 니들펀칭하여 시트용 쿠션재(100)를 제조한다. Next, a
상기 실리콘 섬유 부직포(120)와 폴리아미드 웹(130)은 니들펀칭에 의하여 서로 엉키면서 결합된다. 하지만 이때 실리콘 섬유 부직포(120)와 폴리아미드 웹(130)이 일체로 합체되는 것이 아니라 실리콘 섬유 부직포의 일면에 폴리아미드 웹이 결합되어 있는 상태로 결합된다.The silicone fiber
실리콘 섬유 부직포와 폴리아미드 웹을 니들펀칭으로 결합하지 않고 용액 상태인 접착제(예컨대, 폴리아미드 용액)를 이용하는 경우에는 추후 쿠션재와 표피재를 결합시 표피재에 잔주름이 발생하고 탄성이 저하될 수 있다.
In the case of using an adhesive (for example, a polyamide solution) in a solution state without bonding the silicone fiber nonwoven fabric and the polyamide web by needle punching, fine wrinkles may occur on the skin material and the elasticity may be deteriorated when the cushioning material and the skin material are later combined .
이와 같이 제조된 시트용 쿠션재(100)의 인열강도는 15 내지 25 kgf; 인장강도는 40 내지 45 kgf/5cm; 유연성은 14,000 내지 20,000 mgㆍcm; 탄성율은 30,000 내지 38,000 kg/㎠; 통기성은 7%이하일 수 있다.The tear strength of the
또한, 시트용 쿠션재(100)는 탄성이 높아 고른 압력분포를 보이며, 강도, 쿠션성, 유연성, 탄성, 내습성 및 난연성이 우수하고, 표피재와의 굴곡에 의한 상호 간섭을 최소화하여 제품으로 제조시 표피재에, 특히 영곡면(표면이 접어지는 방향으로 굽어진 곡면)이나 복곡면(2개 이상의 방향으로 굽어지는 곡면)의 부위에 굴곡주름이 형성되지 않는다.

도 2에 도시된 바와 같이, 시트용 쿠션재(100)의 폴리아미드 웹이 구비된 면에 표피재(210)를 구비한 다음 상기 표피재(210)를 히팅롤(heating roll, 220) 측으로, 상기 시트용 쿠션재(100)를 프레스롤(press roll, 230) 측으로 통과시켜 시트용 쿠션재와 표피재를 결합시킨다. 시트용 쿠션재(100)의 폴리아미드 웹이 구비된 면에 표피재(210)를 구비하지 않고 실리콘 섬유 부직포가 구비된 면에 폴리아미드 웹을 구비하면 쿠션재와 표피재가 단단히 결합되지 않을 뿐만 아니라 표피재의 일부는 쿠션재와 결합되고 대부분은 결합되지 않음에 따라 롤을 통과하면서 표피재에 구김이 발생할 수 있다. 2, the
히팅롤(220)에서 발생된 열에 의하여 쿠션재(100)의 폴리아미드 웹이 용해되면서 쿠션재(100)와 표피재(210)가 결합된다.The polyamide web of the
쿠션재는 폴리아미드 웹을 포함하므로 표피재의 종류에 상관없이 높은 접착력을 얻을 수 있지만, 바람직한 표피재로는 천연피혁, 천 또는 합성피혁을 들 수 있다.Since the cushioning material includes a polyamide web, a high adhesive force can be obtained regardless of the kind of the skin material, and preferable skin materials include natural leather, cloth, and synthetic leather.
도 2의 방법으로 제조된 시트재(200)를 이용하면 촉감성과 쿠션성이 우수하고, 굴곡주름 등의 주름이 형성되지 않는 차량용 시트(도 3)를 제조할 수 있다.
