Abstract
A bulky, resilient, durable, dimensionally stable nonwoven fabric is prepared by (a) intermittently attaching contractible elements to a nonwoven fibrous layer, (b) contracting the elements to simultaneously gather the fibrous layer to 25-75% of its original area and form a series of waves or protuberances that project from the plane of the layer and then (c) stitchbonding the gathered fibrous layer with inextensible inelastic yarn. The fabrics are particularly useful for toweling, insulating layers, fire-resistant cloths, upholstery and the like.
