Abstract

The odor removing fibers having biomimetic functions have been developed applying the enzymelike catalytic functions of iron (III) or cobalt (II) phthalocyanine (Fe (III)-, Co (II)-pc) derivatives and their polymers. The oxidoreductase role as antidote against poisonous substance invading the body by activating oxygen in the blood. We have studied the kinetics of model reaction of Fe (III)- or Co (II)-pc derivatives and their polymers, which have similar structure to active center, hematoporphirine IX, of oxidation-reduction enzymes. The Fe (III)- or Co (II)-pc derivatives and remarkably effective catalyst for the metal complexes. Next, various kinds of new odor removing materials by supporting Fe (III)-, Co (II) -octacarboxyphthalocyanines [M-oapc, M = Fe (III), Co (II) ] on various polymer materials and fiber have been developed.<BR>The kinetics of odor removing mechanism of Mt-oapc supporting on porous and amorphous enriched rayon stable fiber have been also investigated.<BR>It was found that the foul oder su bstances such as thiols, amines, etc. can be removed by the enzymelike reaction of Mt-oapc supporting on the rayon fibers. Further, the odor-removing abilities of these fibers by the room for bedridden patients, waste water treatment place and lavatory were evaluated. These results showed trace amount sulfur compounds which are main compound in odor were effectively removed less than 0.1 ppb using the fiber containing Mt-oapc. The fiber eliminated more quantity of the foul oder substances by 20 to 100 times than did activated carbon, and can withstand 50 times of washing.<BR>Applying these properties, new types of odor-removers such as mattress, quilt, blanket, wad, woven, and nonwoven materials produced from odor-removing fibers have been developed.
