ABSTRACT:
A novel adsorptive nonwoven fabric having good strength as well as good permeability and softness and a method of making the same is disclosed. This product consists essentially of supporting fibers containing a heat-fusible fiber and an adsorptive material, said supporting fibers being disintegrated in air before they are admixed with an adsorptive material, and a web is formed from the final mixture followed by being subjected to a heat treatment at a temperature above the melting point of said heat-fusible fiber to firmly fix said adsorptive material in the web by heat-fusion of the heat-fusible fiber.
