Deep drawing method for interlining material for automotive interior trim

Abstract

Abstract PURPOSE:To deep draw while preventing tearing or breakage, by a method wherein a fiber fabric is provided on the surface or in the inside part of an uncured bulky felt obtained by adding a thermosetting resin or the like to a fibrous material as a binder, and the resultant material is pressed with heating. CONSTITUTION:A thermosetting resin or a thermoplastic resin is added as a binder to a fibrous material such as wood fibers, natural fibers, chemical synthetic fibers or a mixture thereof to produce an uncured bulky felt. A fiber fabric having a predetermined tensile strength is provided on one or both sides or in the inside part of the felt, the resultant material is pressed with heating to deep draw it into the interlining material for automotive interior trim. The fiber fabric may be a roughly woven natural fiber fabric such as gauze, a chemical fiber fabric or other nonwoven fabric which has the predetermined tensile strength.
