Process for manufacturing paper from synthetic fibers

Claim 1

A SUBSTANTIALLY CONTINUOUS PROCESS FOR MANUFACTURING PAPER FROM HEAT-SHRINKABLE SYNTHETIC FIBERS SUBJECT TO SHRINKAGE WHEN EXPOSED TO TEMPERATURES ABOVE 180*F. AND BELOW 300*F. WHICH COMPRISES ANNEALING THE HEATSHRINKABLE SYNTHETIC FIBER BY HEATING IT A TEMPERATURE OF NOT LESS THAN 180*F. NOT SUBSTANTIALLY MORE THAN 300* F. TO SHRINK AND DIMENSIONALLY STABILIZE IT, CUTTING THE ANNEALED SYNTHETIC FIBER TO A PREDETERMINED LENGTH, FORMING AN AQUEOUS SLURRY OF THE SYNTHETIC FIBERS, PREPARING A FURNISH FROM THE AQUEOUS SLURRY, SAID FURNISH HAVING A PERDOMINANT PROPORTION OF THE SYNTHETIC FIBERS IN RELATION TO THE TOTAL FIBER CONTENT THEREOF, AND INCLUDING AT LEAST 2% BY DRY WEIGHT OF CELLULOSE FIBERS, FORMING A WET SEB FROM THE FURNISH WHEREIN THE SYNTHETIC FIBERS BECOME INTIMATELY INTERLACED, REMOVING WATER FROM THE WET WEB TO FORM A DAMP SHEET OF SYNTHETIC FIBER PAPER, AND DRYING THE SYNTHETIC FIBER PAPER BY APPLYING HEAT THERETO.
