The stiffener foam 40 uses a thickness of 3 to 6 mm to provide sufficient stiffness.

상기 제4 접착층(41)은 보강재폼(40)의 하면에 돌기형 메쉬천(50)을 접착하기 위해서 사용된다. 돌기형 메쉬천(50)의 상부면에 폴리우레탄계 접착제를 스프레이 도포하여 형성된다. The fourth adhesive layer 41 is used to adhere the protruding mesh cloth 50 to the lower surface of the reinforcing foam 40. And is formed by spraying a polyurethane adhesive onto the upper surface of the protruding mesh cloth 50.

상기 돌기형 메쉬천(50)은 섬유로 이루어진 메쉬천의 일부 표면으로 파이버가 돌출되는 제품이며, 예를 들어, 수 밸크로를 사용할 수 있으며, 0.1~0.5mm 두께의 메쉬천에 1~2 mm 길이의 돌기를 가진다. The protruding mesh cloth 50 is a product in which a fiber protrudes from a part of the surface of the mesh cloth made of fibers. For example, a male thread can be used, and a mesh cloth having a thickness of 0.1 to 0.5 mm may be applied to a mesh cloth of 1 to 2 mm It has a projection of length.

표면층(10)에 형성된 스티치(60)는 메모리폼 스펀지(20)와 부직포(30)를 관통하여 형성된다.The stitches 60 formed on the surface layer 10 are formed through the memory foam sponge 20 and the nonwoven fabric 30.

도 3에 도시된 바와 같이, 본 발명에 따른 바닥재(100)는 섬유가 도포된 차량의 내부 바닥(200)에 수밸크로로 이루어진 돌기형 메쉬천(50)의 돌기들이 걸려서 걸레로 닦거나 발로 밀칠 경우에도 움직이지 않게 된다.As shown in FIG. 3, the floor material 100 according to an embodiment of the present invention includes protrusions of a protruding mesh cloth 50, which is made of a multi-valley, on the inner bottom 200 of a vehicle to which the fiber is applied, Even if it does not move.
