Radiation treatment of high-polymer textile materials

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.

Zusammenfassung:	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 nonirradiated areas of the material. The other method resides in homogeneously irradiating a high-polymer material so as to form chemically active species in the material. The chemically active species in certain areas of the material are at least partially destroyed by contacting selected areas of the material with a suitable medium. The material is again 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 those areas of the material where chemically active species are present will shrink to a different extent in dependence upon the concentration of the chemically active species and/or that those areas of the material where chemically active species are present will shrink to a different extent than the areas where no chemically active species are present.
