ABSTRACT:
A soft, non-woven fabric containing no binding agents and composed, at least in part, of thermoplastic fibers bonded to other fibers at their crossing points, which non-woven fabric is produced by a process which comprises passing a mat composed of said thermoplastic fibers over a surface and to said mat applying an uneven heated surface, said heated surface being sufficient to fuse, at least in part, a portion of said thermoplastic fibers to other fibers at some but not all of their crossing points, while at the same time the fusing is effected without any substantial compression of the fabric.
