Es vnirden Verfahren vorgeschlagen, mit denen Schrumpftextureffekte, gegebenenfalls unter Erzielung von Mehrfarbeneffekten an Dekorationsgeweben aus Glasfaserstoff erreicht werden. Bei diesen Verfahren unterliegen die Flächengebilde einer chemischen oder chemisch-thermischen Behandlung und eignen sich nur für Dekorationsgewebe aus Glasfaserstoff. Methods are proposed with which shrink texture effects, optionally with the achievement of multicolor effects on decorative fabrics made of fiberglass can be achieved. In these processes, the flat structures are subject to a chemical or chemical-thermal Treatment and are only suitable for decorative fabrics made of fiberglass.
Desgleichen sind Verfahren zur Texturierung oder Strukturierung von Flächengebilden bekannt, die im wesentlichen auf einer mechanisch-thermischen Verformung, beispielsweise durch Heißkalander mittels profilierter Kalanderwalzen oder dem unterschiedlichen Schrumpfvermögen von zwei oder mehreren Faserstoffkomponenten beruhen.The same applies to methods for texturing or structuring known of flat structures, which are essentially based on a mechanical-thermal deformation, for example by hot calenders using profiled calender rolls or the different shrinkage capacity based on two or more fiber components.
Bekannt ist auch, daß Faserstoffe und daraus hergestellte Produkte, wie Gewebe, Gewirke und andere textile Flächengebilde bei strahlenchemischen Prozessen einem Schrumpf unterliegen können, der beispielsweise von der Bestrahlungsdosis, der Art des Faserstoffes und von der Art und der Menge der bei den strahlenchemischen Prozessen verwendeten Substanzen abhängt.It is also known that fibrous materials and those made from them Products such as woven, knitted and other textile fabrics in radiation-chemical processes may be subject to shrinkage, for example from the radiation dose, the type of fiber and of the type and quantity of the radiation chemistry Processes used depends on the substances.

Dieser Behandlungsprozeß führt jedoch zu keiner Flächentexturierung, da die Flächengebilde einem homogenen Schrumpf unterliegen.However, this treatment process does not lead to any surface texturing, since the flat structures are subject to homogeneous shrinkage.
Weiter ist bekannt, daß eine strahlenchemische Behandlung hochpolymerer Flächengebilde, insbesondere ein strahleninitiiertes Aufpfropfen von Vinylverbindungen, zu einem veränderten FarbstoffaüfnahmevermÖgen führen kann. Textur- oder Struktureffekte werden dabei aber nicht erreicht.It is also known that a radiation-chemical treatment of high-polymer fabrics, in particular a Radiation-initiated grafting of vinyl compounds, lead to an altered dye absorption capacity can. Texture or structure effects are however not reached.
