Preparation and method for treating hybrid yarns

A preparation (I) for the treatment of hybrid yarn made from glass fibres and polyolefin (preferably polypropylene) fibres contains silanols resulting from the stoichiometric hydrolysis of silanes with water. Independent claims are also included for (1) A method for the treatment of hybrid yarn as a...

Beschreibung
Zusammenfassung:	A preparation (I) for the treatment of hybrid yarn made from glass fibres and polyolefin (preferably polypropylene) fibres contains silanols resulting from the stoichiometric hydrolysis of silanes with water. Independent claims are also included for (1) A method for the treatment of hybrid yarn as above by application of a silanol-containing preparation (I); (2) Hybrid glass/polyolefin yarn treated with (I); and (3) Composite materials and textile sheet material made from this treated hybrid yarn. Es wird eine Präparation zur Behandlung von Hybridgarnen aus Glas- und Polyolefinfasern, insbesondere aus Glas- und Polypropylenfasern, angegeben, die Silanverbindungen aufweist, sowie ein Verfahren zum Behandeln derartiger Hybridgarne, bei dem Silanole auf die Fasern aufgetragen werden. Man möchte die Korrosion der Glasfasern verringern. Hierzu wurde die Präparation mit Wasser in einem stöchiometrischen Verhältnis zu Silanen gebildet.
