Title:
BASE MATERIAL FOR ARTIFICIAL LEATHER AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/081003
Kind Code:
A1
Abstract:
A base material for artificial leather comprising a laminate wherein a nonwoven fabric
layer (A) composed of bundles of ultrafine fibers having an average filament denier
of 0.5 decitex (T) or less and a cushion layer (B) composed of an elastic polymer
sheet are integrated together. Some part of the ultrafine fibers constituting the
nonwoven fabric layer (A) penetrate through the cushion layer (B) and form an
ultrafine fiber layer (C) on the outer face of the cushion layer (B). The inner face
of the elastic polymer sheet has a wavy structure having a vertical interval of
100 μm or more and a space having a height in the thickness direction of 100
μm or more is formed between the wavy face of the elastic polymer sheet and
the nonwoven fabric layer (A). By using the base material for artificial leather as
described above, it is possible to manufacture a skiver-type artificial leather which
shows a less reflective softness and a massive texture comparable to natural sheepskin
and has voluminous folded wrinkles.
