<p><P>PROBLEM TO BE SOLVED: To provide a hygroscopic and deodorant sheet which has moderate gas permeability, is free from the powder leakage of a porous moisture absorbent and an adsorbent of fine particles, has good surface printability, and can be applied to various shapes. <P>SOLUTION: The hygroscopic and deodorant sheet has a laminated nonwoven fabric layer comprising three layers of (A) a thermoplastic synthetic fiber layer, (B) an ultrafine fiber layer, and (C) a thermoplastic synthetic fiber layer having a lower melting point than the (A) thermoplastic synthetic fiber layer; and (D) a nonwoven fabric layer integrally bonded on the (C) thermoplastic synthetic fiber layer side by heat bonding, wherein the particle size of the porous moisture absorbent and the adsorbent are both 1,000μm or smaller, and the porous moisture absorbent and the adsorbent are held between the (C) thermoplastic synthetic fiber layer and the (D) nonwoven fabric layer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
