Abstract (en)
An insulation material for sound wave absorption and for thermal insulation containing thermoplastic staple fibers as matrix fibers and thermoplastic adhesive melt fibers containing a mechanically and thermally strengthened nonwoven, where the nonwoven has a ratio Vair to Vfiber exceeding 40:1, where V = volume, a weight related flexural stiffness of less than 0.5, and a separating strength of at least 3N/5 cm.
Abstract (de)
Isolations-Material zur Absorption von Schallwellen und zur thermischen Isolierung aus thermoplastische Stapelfasern enthaltendem mechanisch und thermisch verfestigtem Vliesstoff. Der Vliesstoff des Isolations-Materials hat ein Volumen-Verhältnis von größer 40 : 1 zwischen Luft und Faserstoff, besitzt ein gewichtsbezogenes Biegesteifigkeitsverhältnis von kleiner 0,5 und hat eine Trennfestigkeit von mindestens 3N/5cm.
