ONE PATTERN IS DISPOSED IN DISCONTINUOUS PORTIONS OF THE FABRIC, EACH OF WHICH PORTIONS INCLUDES AT LEAST ONE PIVOTAL PACKING OF FIBER SEGMENTS PROTRUDING OUT OF THE PLANE OF THE FABRIC AND A PLURALITY OF FLAT, RIBBON-LIKE GROUPS OF ALIGNED FIBERS EXTENDING OUTWARDLY FROM THE PIVOTAL PACKING. THE DISCONTINUOUS PORTIONS OF THE FABRIC ARE BOUNDED OR SURROUNDED BY YARNLIKE BUNDLES OF FIBER SEGMENTS WHICH LIE IN CONTINUOUS PORTIONS OF THE FABRIC BETWEEN THE DISCONTINUOUS PORTIONS AND CONSTITUTE A SECOND PATTERN. THE RIBBON-LIKE GROUPS OF FIBER SEGMENTS CONNECT THE PIVOTAL PACKINGS WITH EACH OTHER AND WITH SURROUNDING YARN-LIKE BUNDLES OF FIBER SEGNENTS.
