Abstract (en)
Biodegradable coating material for fibres, especially elastan fibres, contains biodegradable mineral oil with a viscosity of 2.5-100 (preferably 2.5-50) mPa.s (20 degrees C), a density of 790-880 (preferably 805-860) kg/m<3> (15 degrees C) and a viscosity-density constant (VDC) of 0.770-0.810, preferably 0.775-0.805, most preferably 0.775-0.800. An Independent claim is also included for a process for the production of fibres, filaments or yarn, especially of polyurethane (PUR), in which the surface of the freshly spun or stretched fibre etc. is coated with the above material in amounts of 0.5-15 (preferably 1.5-10, most preferably 2.5-8) wt% based on the wt. of fibre.
Abstract (de)
Die Erfindung betrifft biologisch abbaubare Beschichtungsmittel auf Basis leicht biologisch abbaubarer Mineralöle. Die Erfindung betrifft ferner die Verwendung der Beschichtungsmittel zur Präparation von Kunststoffformkörpern, Fasern oder von Garnen. Insbesondere zeigen die Beschichtungsmittel Vorteile bei der Weiterverarbeitung von mit den Beschichtungsmitteln ausgerüsteten elastischen Polyurethan-Fasern oder daraus hergestellter Flächenwaren.
