Abstract:
The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.
