Abstract

A non-woven material and a method for making it, for use as a backing for a semipermeable membrane which comprises binding fibres, the distribution of which corresponds to that of a wet-laid non-woven material, the binding fibres being fused and flattened, without restriction of the porosity of the material in the surface region of the material.
