PURPOSE:To obtain an excellent deodorant performance against ammonia and hydrogen sulfide, etc., by sticking and fixing Zn(OH)2 in a colloid state to a cellulose system fiber. CONSTITUTION:Zn(OH)2 is sticked and fixed in a colloid state to a cellulose system fiber and fixed. To stick and fix Zn(OH)2 in the colloid state, for instance, a Zn(OH)2 colloid is produced by making pH6.2-12 with an alkaline substance added in the aqueous solution, in which the cellulose system fiber is dispersed, of a water soluble zinc compound, and a colloid is sticked to the cellulose system fiber to be fixed. A Zn(OH)2 colloide can be produced only in a range of PH6.2-12. When pH is high, water washing after fixing is preferable. And the cellulose system fiber can be made acid treatment using acid of hydrochloric acid, sulfuric acid, sulfurous acid, and nitric acid, etc, before the cellulose system fiber is dispersed in the aqueous solution of the water soluble zinc compound. |
