摘要:
A high loft, low density, nonwoven fibrous material is provided comprising two layers of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled fibers, one of the layers including thermoplastic synthetic wood pulp fibers at least in the portion thereof at the interface to the other layer, at least some of the thermoplastic synthetic wood pulp fibers in the one layer being in contact with and fused with segments of fibers of said other layer.The material is produced by air-laying the aforementioned layers successively so that some thermoplastic synthetic wood pulp fibers in one layer are in contact with some fibers in the other layer, and then applying heat without pressure to fuse and bond at least some of the thermoplastic synthetic wood pulp fibers in one layer to fibers in the other layer.
