Abstract:
A method of creping paper webs comprising:a) applying to a rotating creping cylinder a creping adhesive and a creping release aid; b) pressing the paper web against the creping cylinder to effect adhesion of the web to the surface of the cylinder; and c) dislodging the paper web from the creping cylinder with a doctor blade to form a paper product, wherein the creping release aid comprises 0 to about 10% by weight water, 0 to about 20% by weight of one or more emulsifying surfactants and from about 70 to about 100% by weight of a non-oil-based chemical compound selected from the group consisting of alkoxylated alkylphenols, alkoxylated fatty acids and alkoxylated alcohols, wherein the alkoxylated alkylphenol, alkoxylated fatty acid or alkoxylated alcohol is prepared by reacting a C8 to C20 alkylphenol, fatty acid or alcohol with y molar equivalents of propylene oxide and z molar equivalents of ethylene oxide, wherein y plus z is greater than about 20, and y is greater than z, and wherein the y moles of propylene oxide and the z moles of ethylene oxide are added in random or block fashion.
