Claim 1
Independent Claim
178 words
THE PROCESS FOR BONDING CONTIGUOUS FIBERS OF A FIBROUS TEXTILE FABRIC HAVING SUBSTANTIAL THICKNESS AND IN WHICH SURFACE FIBERS HAVE ONE END HELD WITHIN THE FIBROUS STRUCTURE AND ONE FREE END PROTRUDING THEREFROM FORMING A RAISED SURFACE, WHICH COMPRISES FORMING A SOLUTION COMPRISING 1 TO 25 WEIGHT PERCENT OF A LATENT SOLVENT FOR THE FIBERS OF THE FIBROUS TEXTILE FABRIC, CONVERTING THE SOLUTION TO A MIST OF LIQUID PARTICLES HAVING AN AVERAGE PARTICLE SIZE OF LESS THAN ABOUT 0.012 INCH IN DIAMETER, DEPOSITING A CONTROLLED AMOUNT OF THE THUS FORMED MIST CONTAINING THE LIQUID PARTICLES ON CONTIGUOUS FIBERS OF THE TEXTILE FABRIC WHILE SAID FABRIC IS HORIZONTALLY DISPOSED BY PASSING THE MIST OF LIQUID PARTICLES TO THE RAISED SURFACE OF THE TEXTILE FABRIC IN THE ABSENCE OF SUBSTANTIAL PROPELLING FORCE TO SETTLE THE PARTICLES THEREON WITHOUT DISPLACEMENT OF THE FIBERS, AND THEREAFTER BONDING CONTIGUOUS FIBERS ON WHICH THE DISCRETE LIQUID PARTICLES HAVE BEEN DEPOSITED BY HEATING THE TEXTILE FABRIC CONTAINING THE LATENT SOLVENT PARTICLES AT A TEMPERATURE OF ABOUT 215*F. TO ABOUT 350*F. TO ACTIVATE SAID LATENT SOLVENT.
