NONWOVEN FABRIC FOR INTERIOR MATERIAL OF AUTOMOBILE AND AUTOMOBILE INTERIOR MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a nonwoven fabric for an interior material of automobile and suitable as a backing cloth having high elongation, low modulus and excellent softness, following the motion of a surface skin material and foamed material and resistant to the formation of wrinkles and provide an interior material of automobile produced by using the fabric. SOLUTION: The invention discloses (1) a polyamide filament nonwoven fabric having an elongation at break of >=40% and a partial heat-bonded area of 3-30% wherein the polyamide filament nonwoven fabric is produced by using a mixed resin composed mainly of nylon 6 and containing 1-20 wt.% nylon 610 or nylon 612 and the relative viscosity of the nylon 610 or the nylon 612 is higher than the relative viscosity of the nylon 6 by 0.5-4 and (2) an interior material of automobile produced by using the polyamide filament nonwoven fabric as at least a part of the material.
