A METHOD OF CONTINUOUSLY MAKING A BONDED, BRUSHED NONWOVEN FABRIC WHEREIN THE SURFACE FIBERS HAVE BEEN BRUSHED AND EXTEND OUTWARDLY FROM THE MAIN BODY OF THE NONWOVEN FABRIC TO PROVIDE A HIGH DEGREE OF SOFTNESS THERETO, WHICH COMPRISES: BONDING A LAYER OF OVERLAPPING INTERSECTING FIBERS WITH A NON-MIGRATORY BINDER IN A PREDETERMINED PATTERN OF FROM ABOUT 120 TO ABOUT 1100 BINDER AREAS PER SQUARE INCH, THE AVERAGE SIZE OF SAID BINDER AREAS BEING AT LEAST ABOUT 0.00012 SQUARE INCH AND NOT MORE THAN ABOUT 0.0028 SQUARE INCH; CONTINUOUSLY PASSING THE BONDED NONWOVEN FABRIC THROUGH A BRUSHING ZONE; AND DURING SAID PASSAGE CONTINUOUSLY BRUSHING SAID BONDED NONWOVEN FABRIC ACROSS THE ENTIRE WIDTH THEREOF SUBSTANTIALLY UNIFORMLY IN SELECTED PREDETERMINED AREAS TO CAUSE THE FIBERS TO EXTEND OUTWARDLY FROM THE MAIN BODY OF THE NONWOVEN FABRIC A RELATIVELY SHORT DISTANCE DUE TO THE LARGE NUMBER AND SMALL SIZE OF SAID BINDER AREAS, WHEREBY FABRIC SOFTNESS IS INCREASED, FIBER RUPTURE IS MINIMIZED, AND THE STRENGTH OF THE NONWOVEN FABRIC IS NOT MATERIALLY REDUCED.
