Abstract

A tissue sheet includes softwood fibers and treated non-wood fibers from plants in the Poaceae family, wherein the treated non-wood fibers have less than 15 percent hemicellulose. Also, a tissue sheet consists essentially of softwood fibers and treated non-wood fibers, wherein the treated non-wood fibers have less than 15 percent hemicellulose. Customizing the tensile index and Canadian standard freeness (CSF) of fibers in a tissue sheet includes treating non-wood fibers by removing a portion of hemicellulose from the non-wood fibers; forming a tissue sheet comprising softwood fibers and the treated non-wood fibers; and adjusting the portion of hemicellulose removed from the non-wood fibers to achieve a desired the tensile index and Canadian standard freeness (CSF) of the treated non-wood fibers.
