  • Tissue paper containing chemically softened coarse cellulose fibers
    Patent number: 5679218
    Abstract: Tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and napkins are provided. The composite average coarseness of the tissue papers is between about 11 mg/100 m and about 18 mg/100 m. The tissue paper comprise closed cell wall, chemically softened cellulose fibers further comprising coarse cellulose fibers such as those derived from CTMP or recycled sources. The cellulose fibers have enhanced lubricity such that they possess a depressed coefficient of friction (DCOF, in percentage points) related to the composite average coarseness, C, in mg/100 m, by the equation:DCOF>4.27*C-44.23.
