ABSTRACT:
An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.
