Abstract
A dialyser membrane for use in the dialysis of caustic alkali solutions, such as those recovered by expression from cellulose, comprises a woven carrier fabric of synthetic organic, or non-metallic inorganic fibre material, which is chemically inert or resistant to caustic alkali, coated with a coating having a basis of polyvinylalcohol, a polyamide, or a polyurethane. The fabric may be woven from glass, polyvinyl chloride polyamide, or polyurethane fibres. Specification 511,739 is referred to.
