Manufacturing process of an abrasion resistant resin impregnated nonwoven fabric and resin impregnated nonwoven fabric

摘要

Abrasion-resistant nonwoven fabrics are prepared by contracting the area of a lightweight fibrous layer to less than half its original area so that groups of fibers buckle and form inverted U-shaped loops that project from the plane of the layer and then resin impregnating the fabric to immobilize the loops and stabilize the dimensions of the contracted fibrous layer.
