ABSTRACT:
Two basic methods for texturizing or structurizing high-polymer materials are disclosed. One method resides in selectively irradiating a high-polymer material so as to form chemically active species in the material. The material is contacted with a treating medium which reacts with the chemically active species in such a manner as to cause shrinkage of the material. The texturizing or structurizing effects are due to the fact that the irradiated areas of the material will shrink to a different extent in dependence upon the concentration of the chemically active species and/or that the irradiated areas of the material will shrink to a different extent than the non-irradiated areas of the material.
