Abstract 1. A NONWOVEN MAT WHICH COMPRISES SOLELY OF: A PLURALITY OF RANDOMLY DISPERSED SUPERFINE DISCONTINUOUS FIBERS WHICH FIBERS HAVE BEEN PREPARED FROM A MELT-BLOWING PROCESS IN WHICH TWO OR MORE COMPONENTS, ONE OF WHICH IS A THERMOPLASTIC FIBER-FORMING RESIN, ARE BLENDED TOGETHER, EXTRUDED IN THEIR MOLTEN STATE THROUGH A ROW OF DIE OPENINGS IN A DIE HEAD, CONTACTED WITH STREAM OF HOT GAS AT SAID DIE HEAD IN ORDER TO ATTENUATE THE EXTRUDED RESIN IN A DIRECTION AWAY FROM THE DIE OPENINGS TO FORM FIBERS AND COLLECTING SAID FIBERS AT A DISTANCE BETWEEN FROM 1 TO 30 INCHES FROM THE DIE OPENINGS, SAID FIBERS HAVING AVERAGE DIAMETERS OF FROM 0.5 TO 5 MICRONS, WHEREIN EACH FIBER COMPRISES A BLEND OF A MAJOR PORTION OF SAID FIBER-FORMING THERMOPLASTIC RESIN AND AT LEAST ONE OTHER COMPONENT SELECTED FROM THE GROUP CONSISTING OF DYES SUITABLE FOR COLORING SAID BLEND, NON-FIBER FORMING THERMOPLASTIC RESINS AND COMBINATIONS OF THE FOREGOING, WHEREIN SAID BLEND COMPRISES NOT MORE THAN 10 WT. PERCENT OF SAID DYES BASED ON THE TOTAL BLEND, WHEREIN SAID MAT IS FREE OF SHOT AND ROPE AND WHEREIN SAID ONE OTHER COMPONENT IS GENERALLY DISSIMILAR IN CHEMICAL PROPERTIES FROM SAID FIBER-FORMING THERMOPLASTIC RESIN.
