Title:
THERMOCOMPRESSION-BONDING LONG-FIBER NONWOVEN FABRIC HAVING EXCELLENT MOLDING PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2014/069562
Kind Code:
A1
Abstract:
Provided is an inexpensive thermocompression-bonding long-fiber nonwoven fabric suitable as a skin material for an automotive acoustic absorbing material and having excellent molding properties and design properties, and not being subjected to a mechanical interlacing process, the long-fiber nonwoven fabric comprising a polyester-based resin having a melting point of at least 250°C, and the long-fiber nonwoven fabric having a weight of 20-80 g/m2, the sum of the 5% tensile loads in the MD direction and the CD direction being 1.0-1.9 (N/5 cm)/(g/m2), and the 180°C dry heat shrinkage in the MD direction or the CD direction being 3.5% or less.
