Description
본 발명은 가변 돌출형 스위치 커버용 다층복합재 및 그 제조방법에 관한 것으로서, 일정한 신축성을 가지는 친환경 플라스틱인 실리콘계 스킨층과, 탄성섬유로 이루어진 백크로스층을 합포시킴으로서, 신축성, 기계적 물성, 내마모성, 내오염성 및 투과성이 우수한 가변 돌출형 스위치 커버용 다층복합재 및 그 제조방법에 관한 것이다.The present invention relates to a multi-layer composite material for a variable protrusion type switch cover and a method for manufacturing the same, by synthesizing a silicone-based skin layer, which is an eco-friendly plastic having a certain elasticity, and a back cross layer made of elastic fibers, thereby providing elasticity, mechanical properties, abrasion resistance, and resistance. The present invention relates to a multilayer composite material for a variable protrusion type switch cover having excellent contamination and permeability and a method for manufacturing the same.
종래 차량 내장재에 적용되는 인조피혁은 PVC 외에도 폴리우레탄 또는 열가소성 TPO 등이 많이 사용되고 있다. 그러나, 연질 PVC는 다이옥신의 발생 원인으로 밝혀지면서 대체 소재에 대한 요구가 강하게 제기되고 있다.In the conventional artificial leather applied to interior materials of vehicles, polyurethane or thermoplastic TPO, etc. are widely used in addition to PVC. However, as soft PVC is found to be the cause of dioxin, there is a strong demand for alternative materials.
이에 개선된 PU계 원단은 고급화를 이룰 수 있었으나 적층 소재별 접착제를 사용 및 높은 원료비로 제품 단가 상승의 원인이 되는 문제가 발생하였다. Accordingly, the improved PU-based fabric was able to achieve high quality, but the use of adhesives for each laminated material and high raw material cost caused a problem that caused a rise in product cost.
또한 열가소성 TPO 원단은 접합시 본드가 사용되지 않으며 공정 및 원료비용에서 상대적으로 원가절감이 가능하나, 표면 촉감이 딱딱하고 진공성형과 같은 특정한 공법에 최적화되어 있기 때문에 공정 투자비가 많이 발생하여 범용적으로 쉽게 생산하기 어렵다는 한계가 있었다.In addition, the thermoplastic TPO fabric does not use bonds for bonding and can be relatively cost-effective in terms of process and raw material costs, but it has a hard surface and is optimized for a specific method such as vacuum forming. There was a limitation that it was difficult to produce easily.
최근 친환경 생활패턴의 변화로 자동차에서 머무는 시간이 늘어나고 있어 자동차 인테리어용 내장재는 자동차 내부공간에서 운전자 및 승객과 항상 같이 움직이며 호흡하는 제품이기 때문에 그 역할과 기능에서 무엇보다도 다양한 기능 및 성능이 요구되며, 다른 일반적인 자동차 부품에 비해 소비자가 차이점을 쉽게 알고 몸으로 느낄 수 있으므로 감성 요소 및 심미적 요소가 중요하게 대두되고 있다. 이에 따라 기존의 단순한 백라이트 발광형태의 내장재 스위치를 넘어서는 가변 돌출형 스위치와 같은 고급 기능과 심미적인 디자인 형태를 갖춘 차별화된 기술이 요구되고 있다. 이러한 가변 돌출형 스위치에 적용되는 커버용 원단은 기본적으로 높은 인장력, 신축성 및 내구성은 물론이며, 투과성 까지 필요하나 이를 충족하는 원단은 거의 미비한 수준이다.Due to the recent changes in eco-friendly life patterns, the time spent in automobiles is increasing. As interior materials for automobile interiors are products that always move and breathe together with the driver and passengers in the interior space of the automobile, various functions and performance are required above all in their roles and functions. , as compared to other general auto parts, consumers can easily recognize and feel the difference, so emotional and aesthetic elements are emerging as important. Accordingly, a differentiated technology with advanced functions such as a variable protrusion type switch that goes beyond the existing simple backlight-emitting type of built-in switch and an aesthetic design form is required. The fabric for the cover applied to these variable protrusion switches basically requires high tensile strength, elasticity and durability as well as permeability, but there are few fabrics that meet these requirements.
본 발명은 상기의 문제를 해결하기 위하여 고안된 것으로서, 정한 신축성을 가지는 친환경 플라스틱인 실리콘계 스킨층과, 탄성섬유로 이루어진 백크로스층을 합포시킴으로서, 신축성, 기계적 물성, 내마모성, 내오염성 및 투과성이 우수한 가변 돌출형 스위치 커버용 다층복합재 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention is devised to solve the above problems, and by synthesizing a silicone-based skin layer, which is an eco-friendly plastic having predetermined elasticity, and a back cross layer made of elastic fibers, variable elasticity, mechanical properties, abrasion resistance, stain resistance and permeability are excellent. An object of the present invention is to provide a multilayer composite material for a protruding type switch cover and a method for manufacturing the same.

또한, 자동차 내장재로 적용 시, 승객의 피부에 직접 닿고 접촉되는 부위에 적용되므로 차내 안락감 및 고급감 향상은 물론 터치 시 보다 부드럽고 쿠션성 높은 감성을 제공할 수 있다.In addition, when applied as an automobile interior material, it is applied to the part that directly touches and comes into contact with the passenger's skin, so it can improve the comfort and luxury of the vehicle, as well as provide a softer and more cushiony sensibility when touched.
또한, 스킨층에 탄성섬유를 포함하는 백크로스층이 형성되므로, 차량용 내장재로서 감싸기 작업성이 보다 용이해지며, 스위치 형태에 따른 신축 및 복원성능 자유도도 더욱 우수해지는 효과를 가진다.In addition, since a back cross layer including elastic fibers is formed on the skin layer, wrapping workability as an interior material for a vehicle becomes easier, and the degree of freedom of expansion and contraction and restoration performance according to the switch shape is further improved.

다음으로, 백크로스층에 대해 상세히 설명한다.Next, the backcross layer will be described in detail.
상기 백크로스층은 신축성이 우수한 폴리우레탄계 탄성섬유를 포함하는 원단으로서, 통상 스판텍스(Spandex) 또는 엘라스테인(Elastane), 크레오라(Creora) , 라이크(Lycra)라고 호칭되는 원단일 수 있다.The back cross layer is a fabric including a polyurethane-based elastic fiber having excellent elasticity, and may be a fabric commonly called Spandex, Elastane, Creora, or Lycra.
상기 백크로스층은 원착사 스킨층의 실리콘 재질 칼라 매칭성이 용의하다는 장점을 가지며, 내구성을 더욱 높여 줄 뿐만 아니라 신축성 및 반복내구력 등의 성능 역시 높일 수 있다.The back cross layer has the advantage that it is easy to match the color of the silicone material of the original yarn skin layer, and not only further increases durability, but also improves performance such as elasticity and repeat durability.
본 발명에 따른 상기 백크로스층은 폴리우레탄계 원사 외에, 폴리에스터, 나일론, 아크릴, 코튼, 울, 레이온 또는 폴리아미드 소재의 원사 등을 함께 교편, 교직하여 제조할 수 있다. 본 발명의 일 구체예로 상기 백크로스층은 폴리우레탄계 원사를 주재로 하고, 폴리에스터 원사와 혼?d형태로 제조할 수 있다. 이는 상기 폴리에스터 원사가 내열성, 내습성 및 기계적물성이 우수하기 때문이다. 이때 주재인 폴리우레탄계 원사와 폴리에스터계 원사를 각각 95:5 내지 60:40 비율로 하여 제조하는 것이 보다 바람직하다.The back cross layer according to the present invention may be manufactured by interweaving and interweaving yarns made of polyester, nylon, acrylic, cotton, wool, rayon, or polyamide in addition to polyurethane-based yarns. In one embodiment of the present invention, the back cross layer is mainly made of a polyurethane-based yarn, and may be manufactured in the form of a polyester yarn and a blend-d type. This is because the polyester yarn is excellent in heat resistance, moisture resistance and mechanical properties. In this case, it is more preferable to prepare the polyurethane-based yarn and the polyester-based yarn in a ratio of 95:5 to 60:40, respectively.
상기 백크로스층은 원사를 니트 또는 트리코트 형태로 형성시키고, 루프 형태를 길이 방향으로 연결시켜 더블 니트 메쉬 구조를 형성할 수 있다. 여기서 더블 니트 메쉬 원단이라 함은 원사를 더블 니트 방식으로 제직(製織)하여 제조한 것을 의미한다. 보다 구체적으로, 원사를 원단의 폭 방향으로 제공하며, 제공된 원사를 루프 형태로 형성시키고, 형성된 루프 형태를 순차적으로 원단의 길이 방향으로 연결시켜 제조할 수 있다.The back cross layer may form a double knit mesh structure by forming yarns in a knit or tricot form, and connecting loops in a longitudinal direction. Here, the double knit mesh fabric means a fabric manufactured by weaving yarn in a double knit method. More specifically, it may be manufactured by providing the yarn in the width direction of the fabric, forming the provided yarn in a loop shape, and sequentially connecting the formed loop shape in the length direction of the fabric.
바람직하게는 상기 백크로스층을 이루는 원사의 굵기가 10 내지 80 D(denier)일 수 있고, 보다 바람직하게는 30 D일 수 있는데, 이는 상기 범위에서 신율 및 원단의 신축성에 대한 원단 복원력이 우수하기 때문이다.Preferably, the thickness of the yarn constituting the backcross layer may be 10 to 80 D (denier), and more preferably 30 D, which has excellent fabric restoring force with respect to elongation and elasticity of the fabric in the above range. Because.
상기 스킨층은 0.1 내지 1.0 mm일 수 있고, 상기 백크로스층은 0.2 내지 0.8 mm일 수 있는데, 상기 범위에서 보다 신율 및 원단 복원력이 우수하기 때문이다.The skin layer may be 0.1 to 1.0 mm, and the back cross layer may be 0.2 to 0.8 mm, because elongation and fabric restoring force are superior to those in the above range.
또한, 상기 슬립용 실리콘층은 착색제인 무기안료를 더 포함할 수 있는데, 그 투입량은 상기 슬립용 실리콘층 전체 중량 기준으로 상기 무기안료를 0.2 내지 10 중량% 일 수 있다. 도 6에서 투입되는 무기안료의 첨가량에 따른 투과성 및 선명도가 차이가 발생하게 된다.In addition, the silicone layer for slip may further include an inorganic pigment as a colorant, and the amount may be 0.2 to 10% by weight of the inorganic pigment based on the total weight of the silicone layer for slipping. In FIG. 6 , there is a difference in transmittance and clarity according to the amount of inorganic pigment added.
