NON-WOVEN STRUCTURE USING FIBROUS WAD COMPOSED OF RANDOMLY DISTRIBUTED STAPLE FIBER AND PRODUCTION OF THE SAME STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a cushion material scarcely causing deformation due to swelling and/or compression after been loaded in a high temperature atmosphere. SOLUTION: This non-woven structure constituted by adhering many fibrous wads composed of staple fibers features that the fibrous wads comprise matrix fibers and binder fibers and substantially are adhered to one another in part of mutual contact zones, and that the staple fibers making up the fibrous wads are distributed so as to be directed randomly within at least two planes of the wads themselves.
