Abstract (en)
[origin: WO0220635A2] The invention relates to a wet-strength filter, especially a depth filter with a high swelling capacity. Said filter comprises an open-pored filter matrix containing cellulose fibers and having cavities, said cellulose fibers having chemically bonded polyisocyanate on the surface. According to a preferred form of embodiment, the filter matrix contains finely dispersed microparticles in its cavities. The invention also relates to a method for producing a filter of this type and to the use thereof in the food, beverages and pharmaceutical industries.
