Abstract: The slip-proof trouser hanger faultlessly stretches trousers hung thereupon. The legs of the trousers cannot slide off from stretching prongs of the trouser hanger and the material of the trousers is not undesirably deformed or distorted by the trouser hanger. Differences in the width of the trousers' legs are permitted and compensated for by one movable pair of stretching prongs at a stretching rod of the trouser hanger. It is of significance in the design of the trouser hanger that engaging edges for engaging the legs of the trousers in the movable pair of stretching prongs are rearwardly offset with respect to a pivot axis of such movable pair of stretching prongs, i.e. in a direction towards the other pair of stretching prongs, by an amount in the range of about 3 to about 4 mm.

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 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.
