Claim 1

A METHOD OF FORMING A WEB PRODUCT COMPRISING THE STEPS OF FORMING A STABLE DISPERSION OF FINELY DIVIDED PARTICLES OF POLYVINYL CHLORIDE RESIN IN DIOCTYL PHTHALATE, SAID DISPERSION HAVING A VISCOSITY WITHIN THE RANGE OF 2900 TO 16,000 CENTIPOISES, SAID DISPERSION CONTAINING 42 TO 46 PARTS BY WEIGHT OF POLYVINYL CHLORIDE RESIN, APPLYING SAID DISPERSION OVER AT LEAST A PORTION OF THE SURFACE OF A THREAD WEB, HEATING SAID THREAD WEB HAVING SAID DISPERSION THEREON TO A TEMPERATURE OF BETWEEN 240 TO 295* F. TO ONLY PARTIALLY FUSE SAID POLYVINYL CHLORIDE RESIN IN SAID DIOCTYL PHTHALATE AND THEREBY SOLIDIFY SAID DISPERSION ON THE THREADS OF SAID WEB WITHOUT SUBSTANTIAL IMPREGNATION OF RESIN WITHIN SAID THREADS, DEPOSITING AN APPLIQUE OF SEPARATED FIBERS ON THE SURFACE OF SAID WEB HAVING SAID SOLIDIFIED DISPERSION THEREON, REHEATING SAID FIBER CONTAINING WEB TO A TEMPERATURE OF BETWEEN 265 AND 320* F. TO SOFTEN SAID DISPERSION AND TO CAUSE FURTHER FUSION OF SAID RESIN, AND CALENDERING SAID FIBER CONTAINING WEB WHILE IN SAID HEATED CONDITION TO BRING THE WEB AND APPLIQUE INTO INTIMATE CONTACT WITH SAID DISPERSION WHEREBY THE WEB AND APPLIQUE ARE EMBEDDED IN SAID DISPERSION, SAID REHEATING BEING INSUFFICIENT TO COMPLETELY FUSE SAID POLYVINYL CHLORIDE RESIN WHEREBY SAID DISPERSION REMAINS SOLIDIFIED ON THE SURFACE OF THE THREADS OF SAID WEB WITHOUT SUBSTANTIAL IMPREGNATION OF RESIN WITHIN SAID THREADS.
