<p><P>PROBLEM TO BE SOLVED: To solve the problem that, when functional particles are firmly fixed with an increased amount of binder, the air-flow resistance is increased and also the function of the particles cannot be developed fully, and to permit the used nonwoven fabric to be easily disposed of. <P>SOLUTION: The particle-including nonwoven fabric has a layer including 50-500 wt.%, based on the weight of the nonwoven fabric, of particles with an average particle size of 100-1,000μm in the nonwoven fabric mainly comprising electlet-made aliphatic polyester fiber and the particles are fixed to the fabric by its thermal shrinkage of the nonwoven fabric made mainly of the aliphatic polyester. <P>COPYRIGHT: (C)2004,JPO</p> |
