Transversely tearable textile sheet, e.g. supporting sheet or non-woven, comprises longitudinal fibers embrittled by brief, targeted application of energy

A textile sheet (41), consisting mainly of longitudinally oriented fibers (42), is such that brief, targeted application of energy over the whole sheet surface causes an increase in the degree of crystallization of the longitudinal fibers at the molecular level and/or embrittlement of the fibers, so...

Beschreibung
Zusammenfassung:	A textile sheet (41), consisting mainly of longitudinally oriented fibers (42), is such that brief, targeted application of energy over the whole sheet surface causes an increase in the degree of crystallization of the longitudinal fibers at the molecular level and/or embrittlement of the fibers, so that transverse tearing of the sheet is possible. Die vorliegende Erfindung betrifft ein textiles Flächengebilde, welches aus vorrangig längsorientierten Fasern gebildet ist. Durch eine gezielte Einbringung von Energie in das textile Flächengebilde wird dieses in Querrichtung zur Orientierung der Fasern reißbar.
