Spunbonded nonwoven fabric and process for making the same

A spunbonded textile fibre of theoretically infinite length has a bi-component filament with an inner core and an outer sheath with a low melting point. The spun filament is strengthened by calander with a press surface of less than 22% and has a specific weight of less than 40 g/m. An independent c...

Beschreibung
Zusammenfassung:	A spunbonded textile fibre of theoretically infinite length has a bi-component filament with an inner core and an outer sheath with a low melting point. The spun filament is strengthened by calander with a press surface of less than 22% and has a specific weight of less than 40 g/m. An independent claim is included for a process to produce the spunbonded fibre. Spinnvlies aus Endlosfasern, wobei die Endlosfasern Mehrkomponentenfilamente, insbesondere Bikomponentenfilamente mit einer niedrig schmelzenden Komponente an der Außenoberfläche sind. Es handelt sich um eine thermisch in einem Kalander verfestigtes Spinnvlies. Das Spinnvlies weist ein Flächengewicht von über 40 g/m auf.
