ABSTRACT:
Nonwoven fabrics of improved abrasion resistance are produced by applying to a dry-laid fibrous web an aqueous dispersion of ultra-short fibers of 50 to 300 microns in length, said ultra-short fibers being coated with a polymeric binder and being suspended in an aqueous phase which is substantially free of binder. The dry-laid fibrous web may be bonded in a separate operation, optionally with a different polymeric binder and in a discontinuous pattern.
