Laminated deodorant filter medium and method of making the same |
摘要 |
A laminated deodorant filter medium is constituted by a plurality of laminate units (19;21) laminated together; each of which includes a fiber web (15) constituted by a connecting portion (11) and a resin-aggregating portion (13), both of which are made of a hotmelt resin, and a deodorant particle (17) firmly attached to one surface of the fiber web (15) by way of the resin-aggregating portion (13). Employable as the deodorant particle is at least two kinds of deodorant particles including an acidic odor deodorant particle, an alkaline odor deodorant particle, and a physically adsorbing particle. As the resin-aggregating portion is formed at a part where a hotmelt nonwoven fabric and the deodorant particle are in contact with each other, the deodorant particle can be firmly attached to the fiber web as a single layer without using a binder, whereby a deodorant filter medium having a low pressure loss and high efficiency can be obtained. <IMAGE> |
