Abstract:
The present invention is directed to a method for scouring and increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers, exposing the mixture to a scouring liquor and a scouring agent comprising oxygen gas to form a scouring mixture, and scouring the scouring mixture by radially circulating the scouring liquor throughout the scouring mixture to provide scoured fibers.
