Claim 10

A process for making a soft, absorbent tissue paper web comprising the steps of (1) forming an aqueous papermaking furnish; (2) forming from said papermaking furnish a fibrous pattern densified embryonic web having a multiplicity of discrete zones of relatively high density disposed in a predetermined pattern array; (3) supporting said embryonic web on an array of spaced supports so that each of a predetermined sub-array of said high density zones is justaposed one of a predetermined sub-array of said supports; (4) at least partially impregnating at least a substantial proportion of the supported predetermined sub-array of said high density zones with a binder by biasing said predetermined sub-array of said supports towards a contacting type impregnating means with said sub-array of said high density zones disposed between said sub-array of said supports and said impregnating means; (5) drying said embryonic web; and (6) creping said dried web wherein said papermaking furnish is an aqueous slurry comprising: (a) papermaking fibers; (b) at least one quaternary ammonium compound having the structure ##STR4## wherein R is an aliphatic hydrocarbon radical selected from the group consisting of alkyl radicals having from about 12 to about 18 carbon atoms, alkylene radicals having from about 12 to about 18 carbon atoms, coconut, and tallow, X is halogen, m and n are both integers each having a value of at least 1, and the sum of m and n is from about 2 to about 15; and (c) at least one nonionic surfactant selected from the group consisting of (1) ethylene oxide adducts of fatty alcohols; and (2) ethylene oxide adducts of fatty acids wherein said fatty alcohols and fatty acids each have from about 12 to about 18 carbon atoms and wherein said adducts contain from about 2 to about 12 moles of ethylene oxide; wherein said quaternary ammonium compound is present at from about 0.5 to about 5.0 grams per kilogram of papermaking fiber and said nonionic surfactant is present at from about 0.5 to about 5.0 grams per kilogram of papermaking fiber.
