Title:
DEODORANT MATERIAL AND PROCESS FOR ITS PRODUCTION
Document Type and Number:
WIPO Patent Application WO/1989/012713
Kind Code:
A1
Abstract:
A process for producing cellulosic deodorant fibers having a remarkable amount of copper and/or zinc hydroxide firmly fixed thereto, which comprises bringing cellulosic fibers into contact with a solution containing a copper and/or zinc hydroxide colloid formed by adding an alkaline substance to an aqueous solution of a water-soluble copper and/or zinc compound. The obtained fibers exhibit an excellent deodorant action whereby various malodorous gaseous components such as hydrogen sulfide, ammonia or mercaptan can be efficiently removed. Although the fibers can be employed by themselves as an excellent deodorant material, they have such an excellent processability that they can be processed into various shapes such as a granule or a sheet and applied to a wide field of deodorization.
