100℃) Aqueous emulsion “Acronal 1100D”
(trade name, solid content 46% by weight)" was applied with a Ritzker roller to a solid content of 250g/ m2 , and then the emulsion was applied with a Nipprol to 50% of the thickness of the fiber mat. The fiber mat of the present invention was manufactured by impregnating the fibers until the end of the process.

This is made using a press mold at 140°C with a wall thickness of approximately 6mm.
The carpet was heated and pressure-molded for 5 minutes at a pressure such that the carpet was molded under pressure, and then cooled to obtain a carpet having an uneven shape.

た場合、うき上りはなくフロアによく適合した。 This carpet had high surface elasticity, and the portion corresponding to the back layer of the fiber mat bonded to the felt was highly rigid. In addition, the shape retention of this carpet was good, and when it was laid on the floor of an automobile, it did not rise up and conformed well to the floor.
