Abstract
In the manufacture of soft tissue products such as facial and bath tissue, a creping adhesive composition comprising from about 0.05 to about 20 dry weight percent of an ethoxylated acetylenic diol has been found to reduce skulch, improve creping blade life, and improve crepe quality. The creping adhesive composition is particularly useful for creping throughdried tissue webs.
Claims15
A method of making a creped tissue comprising the steps of:
- (a) depositing an aqueous suspension of papermaking fibers onto a forming fabric to form an embryonic web;
- (b) dewatering and drying the embryonic web to form a tissue web;
- (c) applying a creping adhesive to the surface of a creping cylinder;
- (d) adhering the tissue web to the creping cylinder;
- and
- (e) dislodging the tissue web from the creping cylinder with a doctor blade to form a soft tissue sheet, wherein the creping adhesive comprises from about 0.05 to about 20 dry weight percent of an ethoxylated acetylenic diol having the formula:
- ##STR2## wherein the sum of m+n is from about 1 to about 10.

- (e) dislodging the tissue web from the creping cylinder with a doctor blade to form a soft tissue sheet, wherein the creping adhesive comprises from about 50 to about 90 dry weight percent of a semicrystalline polymer selected from the group consisting of polyvinyl alcohol and polyvinylpyrrolidone, from about 10 to about 50 dry weight percent of a polyamide having an intrinsic viscosity of from about 10 to about 200 cubic centimeters per gram, and from about 1 to about 20 dry weight percent of a release agent comprising from about 5 to about 95 dry weight percent of an ethoxylated acetylenic diol of the formula:
- ##STR3## wherein the sum of m+n is from about 1 to about 5, said release agent having a cloud point of about 60 or less and a dynamic surface tension of about 40 dynes per centimeter or less.
