Abstract: A sanitary paper product made from newspapers containing coarse cellulosic fibers and printed with ink that contains oil and a method for making the same is provided. The method has the step of (a) pulping the newspapers in water with agitation to produce a pulp slurry at a consistency between 3% and 12% and a pH below about 8.0; (b) adding to the slurry an enzyme selected from the group consisting of cellulase, hemicellulase, and lipase and maintaining the pulp slurry at a temperature above about 100.degree. F. for at least 15 minutes; (c) maintaining at least about 2% of the oil in contact with the newspaper fibers beginning with the making of the pulp slurry in step (a) through step (b); and using the enzyme treated pulp as a major source of fiber in the paper making process to produce sanitary paper products.

Abstract: This invention provides an integrated system for recovering fibers from mixed grades of waste paper and simultaneously cleaning (deinking) waste fibers. The system comprises a mild alkaline pulping process with oxygen and hydrogen peroxide followed by rapid decompression of fibers and then by hot washing.

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.
