Abstract:
An apparatus for performing a continuous radiation-induced graft polymerization treatment on substrates in the form of a web of woven or non-woven fabric, which comprises a series arrangement of an electron beam exposing unit for applying electron beams to a substrate in the form of a web of woven or non-woven fabric in a nitrogen atmosphere, a monomer impregnating vessel for bringing the irradiated substrate into contact with a specified amount of a monomer in a nitrogen atmosphere and a graft polymerization vessel for grafting the monomer onto the substrate in a nitrogen atmosphere, which apparatus further including a transport means by which the substrate web of woven or non-woven fabric is continuously passed through said units of the apparatus in the order written, the graft polymerization vessel including sheet transport rolls which form a long, zigzag pathway of the substrate web.
