Abstract
Fibrous cellulosic products incorporating both conventional cellulosic fibers and laterally expanded cellulose fibers exhibit exceptional porosity, bulk, absorbency and resiliency properties. Typical products include absorbent tissue products, absorbent fluff products and flat papers. The laterally expanded cellulose fibers exhibit: (i) a broadened X-Ray diffraction peak for the most prominent reflection having a width at half-height, (W), of at least about 3.0° 2Θ, (ii) broad overlapping maxima in their Raman spectrum between 285 and 500 cm, the height of the two tallest of said maxima in said spectrum between 285 and 500 cmbeing between 35 and 50% of the height of the peak near 1098 cmand (iii) a blue stain when treated with Graff C-stain, the stain exhibiting less red than the stains exhibited with bleached hardwood kraft fibers and bleached softwood kraft fibers.
