Plastic foil texturizing machine - for poly,er foil contg cleavage fibres with latentcrimp

Plastic, esp. polyolefins; is exposed to high energy radiation esp. a beam of electrons, in such a way that differential cross linking build up or grafting takes place between the fibres. The foil is pre-stretched on one axis before treatment. The process may be reinforced by creating a temp. gradie...

More Information
Summary:Plastic, esp. polyolefins; is exposed to high energy radiation esp. a beam of electrons, in such a way that differential cross linking build up or grafting takes place between the fibres. The foil is pre-stretched on one axis before treatment. The process may be reinforced by creating a temp. gradient across the thickness of the foil e.g. by warm air from below and cooling air from above. Simplicity and high prodn. capacity.
