摘要： A method of making regenerated cellulose microfibers includes forming segmented fibers with multiple longitudinally-extending segments of slightly different composition such that there is defined splittable interfaces between juxtaposed segments of the fibers which are then split into microfibers at yields of greater than 50%. Fibers so produced may be incorporated into absorbent sheet with other papermaking fibers to provide strength, softness, bulk and absorbency to tissue, towel, and personal care products.
