絡合分が、耐熱性芳香族ポリアミド繊維よりなる低融点
のため溶融し、両者は強固に一体化される。As a result, the surface of the fiber layer made of heat-resistant aromatic polyamide fibers is burnt and smoothed, and the fibers made of heat-resistant fibers are dispersed into the fiber layer made of heat-resistant aromatic polyamide fibers by needle punching. The fiber entangled portion of the layer melts due to the low melting point of the heat-resistant aromatic polyamide fiber, and the two are firmly integrated.
なお、上記耐熱性芳香族ポリアミド繊維よりなる繊維層
の表面の毛焼きは、予めなされていてもよい。Note that the surface of the fiber layer made of the heat-resistant aromatic polyamide fiber may be burnt in advance.

、平滑化しているので、繊維くずやガラスクロスの粉末
が鏡面板や熱板へ付着することもない上、これらへのな
じみもよく、これら両繊維層も強固に一体化される。Moreover, since the surface of the fiber layer made of heat-resistant aromatic polyamide fiber is pressed with a heat roll or the like to burn it, melt it, and smooth it, fiber scraps and glass cloth powder will not adhere to the mirror plate or hot plate. Not only that, but it also conforms well to these layers, and both of these fiber layers are firmly integrated.
また、表面が耐熱性芳香族ポリアミド繊維よりなる繊維
層よりなるので、抜群の耐熱性がある。Furthermore, since the surface is made of a fiber layer made of heat-resistant aromatic polyamide fibers, it has excellent heat resistance.
更に、中間シートの存在によりクッション材全体の伸び
も規制出来、その取扱いもこしが出来て容易である。Furthermore, the presence of the intermediate sheet makes it possible to control the elongation of the entire cushioning material, making it easy to handle.
