Abstract:
1. A fibrous cellulosic product, comprising conventional cellulosic fibers and laterally expanded cellulose fibers, exhibiting a broadened X-Ray diffraction peak for the most prominent reflection having a width at half-height, (W 1/2h ) A , of at least about 3.0° 2θ, said laterally expanded cellulose fibers exhibiting at least two broad overlapping maxima in their Raman spectrum between 285 and 500 cm −1 the height of the two tallest of said maxima in said spectrum between 285 and 500 cm −1 being between 35 and 50% of the height of a peak near 1098 cm −1 ; said at least two maxima between 285 and 500 cm −1 being at least 10% broader at half height than the corresponding maxima in the pulp from which said laterally expanded cellulose fibers were prepared.
