Abstract

A method to prepare, pulp, and bleach cannabis bast and hurd fibers to allow for the fiber to be incorporated into absorbent cellulosic structures on a wet-laid paper machine while keeping the pectin within the fibers. The wet laid paper machine can use the ATMOS, NTT, ETAD, TAD, or UCTAD method to produce the absorbent cellulosic structure. Absorbent cellulosic structures are produced with the cannabis bast and hurd fibers or with the bast fibers alone with the hurd fibers being combined with paper mill sludge or dust to form a fuel pellet.
