Estimating the term…
An absorbent sheet of cellulosic fiber typically includes at least about 15% by weight of high coarseness, generally tubular and lignin-rich cellulosic fiber based on the combined weight of cellulosic fiber in the sheet. Lignin-rich high coarseness, generally tubular fiber employed may be characterized by a coarseness of at least about 20 mg/100 m and an average length of 2 mm. The sheet is prepared by way of a process including applying a dewatered web to a heated rotating cylinder and creping the web from the heated cylinder with an undulatory creping blade. Preferred lignin-rich, high coarseness, generally tubular fibers include thermo and chemi mechanical pulps. A particularly preferred embodiment is a sheet including at least about 15% BCTMP.
