Creping adhesive and products and process incorporating same

Abstract

The present invention is generally directed to base webs that are creped after a bonding material has been applied to at least one side of the web according to a predetermined pattern. According to the present invention, the bonding material contains a creping adhesive mixed with composite particles. The composite particles generally have a median particle size of less than about 5 microns and a particle size distribution of less than about 10 microns.
