ABSTRACT:
Creping of fibrous webs to enhance their softness and bulk is improved and the resulting creped web is made strong, water dispersible and non-blocking by employing a bonder and creping adhesive composition containing four components which are blended to produce a mixture having a percent solids of from 10% to 40% and an initial modulus for a film of the solids of less than 1.75 .times. 10.sup.8 dynes/cm.sup.2. The composition (mixture) functions as a bonder for the fibers to impart strength and as a creping adhesive for the web so that creping enhances softness and bulkiness. Also disclosed are methods of creping employing such a bonder and creping adhesive composition and sheet materials creped with such compositions.
