Abstract: THE ARTICLE IS MANUFACTURED BY WINDING A FILAMENT COMPOSED OF POLYMERS WHEREIN ONE POLYMER IS DISPERSED AS FIBRILS IN A LOWER MELTING POINT POLYMERIC MATRIX ONTO A MANDREL FOLLOWED BY BONDING THE FILAMENTS TOGETHER THROUGH HEATING THEM TO A TEMPERATURE ABOVE THE MELTING POINT OF THE MATRIX-FORMING POLYMER BUT BELOW THE MELTING POINT OF THE DISPERSED FIBRILS AND PERMITTING THEM TO BOTH SELF-BOND AND SELF-COMPACT DUE TO SHRINKAGE THEREOF.
