TH36940B - A hydrophilic fiber sheet with modified polyvinyl alcohol. - Google Patents

Abstract

DC60 (24/12/42) Filament sheet using modified polyvinyl alcohol. Is a binder with a solution of Liquids containing soluble organic salts, dissolved inorganic salts and / or soluble boron compounds Thus, the wet strength of the fibers can be maintained. It has a very good hydrophilicity and strength, and dissociation capacity. Got in the water and its strength has not decreased Although at high temperatures, it can also crack. It is very good in water. Although in cold water Fibrous panels using modified polyvinyl alcohol. Is a binder with a solution of Liquid containing dissolved organic salts Water soluble inorganic salts and / or water soluble byron compounds. Thus, the wet strength of the fibers can be maintained. It has a very good dissolution in water and is strong. And the ability to break Got in the water and its strength has not decreased Although at high temperatures, it can also crack. It is very good in water. Although in cold water
