PAPER MADE WITH CELLULOSE FIBERS HAVING AN INNER CORE OF CELLULOSE ACETATE

摘要

A composition of paper comprising 99 to 10 weight percent cellulose fibers and 1 to 90 weight percent cored cellulose fibers that are uniformly dispersed within the paper. The cored cellulose fibers are composed of a cellulose sheath that is 4 to 15 weight percent of the weight of the fiber and a cellulose acetate core. The cored cellulose fibers contain no substantial crimp and have an average length of 1 to 7 mm, a density of 1.20 to 1.35 gm/cc, a denier 1 to 30 grams per 9,000 meters and a uniform dispersion index of less than 0.15.
