響を及ぼすという問題点があった。[0003] The novolak type phenol resin used as a binder contains 8 to 15% by weight of hexamine as a curing agent, so that gas components such as ammonia and formaldehyde which adversely affect the human body are generated at the time of molding, thereby reducing the working environment. In addition to being contaminated, it also remains inside the molded product, and when used as an interior material for automobiles, there is a problem that an ammonia odor is generated and adversely affects the environment inside the automobile.

ない。The saccharide is used as an aqueous solution, and the water content at this time is preferably 25 to 45% by weight. If the water content of the saccharide is less than 25% by weight, the viscosity of the saccharide becomes high and it is difficult to mix uniformly with the fiber. On the other hand, if the water content exceeds 45% by weight, separation occurs at the time of mixing with the polyisocyanate compound, In any case, sufficient strength cannot be obtained.

も、多くとも成形物の強度は不十分なものとなる。The fibrous material has a water content of 5 to 3 in advance.
It must be adjusted to 0% by weight. At least the moisture content of the molded product is insufficient at most.

臭気となる。[0011] The molded felt obtained by the present invention has an increased bonding strength with the fiber and an increased bending strength due to the strong adhesive force of the reaction product of the saccharide and the polyisocyanate compound. Further, in the reaction between the saccharides and the polyisocyanate compound, the molded felt obtained has a low odor because no gas is generated.
