ABSTRACT:
Paper products such as bathroom tissue, facial tissue, napkins and paper towels are made from high coarseness fibers such as recycled newsprint fibers, CTMP, TMP, and groundwood. These products exhibit premium level qualities in terms of softness, bulk, and flexibility. The novel process selectively treats these high coarseness fibers in a way that makes the fibers feel softer and enhances papermachine operation with this type of furnish, thereby permitting higher product quality levels than previously possible with high coarseness fibers.
