<p>PROBLEM TO BE SOLVED: To increase a deodorizing effect and to realize low pressure loss by fixing deodorizing granules through a resin aggregate on one surface of a web comprising a hot-melt resin connecting part and the resin aggregate. SOLUTION: The web 15 consists of a connecting part 11 and a resin aggregate part 13 and both are consists of a hot-melt resin. The web 15 is obtd. by heat treating a hot-melt nonwoven fabric while the fabric is in contact with a deodorizing powder 17. As for the hot-melt resin from which the web above described can be produced, a thermoplastic polyamide resin, thermoplastic polyester resin, thermoplastic polyurethane resin, polyolefin resin, ethylene-vinyl acetate copolymer resin, etc., can be used in a single or mixed state. As for the deodorizing powder 17, the powder is preferably controlled to have the average particle size of >=0.147 mm (100 mesh) and <=1.65 mm (10 mesh) so as to obtain high efficiency and low pressure loss.</p> |
