Title: Antimicrobial and deodorizing carpet
Inventor: KOBAYASHI IKUO
IPC: D03D15/00
Filed: 1989-05-16
Abstract: PURPOSE:To obtain the carpet which has a high deodorizing effect and has a sterilizing effect by disposing fibers subjected to a antimicrobial finishing and catalyst type deodorant fibers contg. a metal chelate to at least a part of the carpet. CONSTITUTION:The carpet constitutes the piles 2 formed by applying the deodorant fibers 4 on a base fabric 1 applied with the antimicrobial fibers 5 and the rear surfaces is packed with a latex 3. For example, the chromatic deodorant fibers 4 are the deodorant fibers in the form of a metal chelate-contg. catalyst type and the metal chelate catalyst is a phthalocyanine deriv. and a chelate compd. having a porphyrin nucleus. For example, the moth-proof fibers 5 are formed by depositing the quaternary ammonium salt of silicone on polyester, nylon, acryl, rayon, cotton, and wool. Since the chromatic deodorant fibers 4 are blended with the piles, the area in contact with the air in a room is wide and the deodorizing effect increases. The malodor in the room and the smells penetrated in the piles are thereby more effectively decomposed and neutralized. The propagation of bacteria in the base fabric 1 is entirely obviated by applying the moth-proof fibers 5 on the base fabric 1 and the propagation of bacteria even under the piles and carpet is entirely obviated as well.
