VERWENDUNG EINES CELLULOSISCHEN FORMKÖRPERS

摘要

The invention relates to the use of a cellulosic moulded part produced by the amine oxide method and treated with an enzyme capable of breaking down cellulose or another substance contained in said moulded part, as a membrane. The invention further relates to a method for producing a cellulosic membrane by producing a moulded part from a solution of cellulose in an aqueous tertiary amine oxide. Said method is characterized in that the moulded part contains a substance (A) which differs from cellulose and can be broken down by enzymes and in that said moulded part is treated with an enzyme capable of breaking down said substance (A).
