Abstract: The present invention is directed to a method of increasing the brightness of non-wood fibers and nonwoven fabric fabrics produced by the method. In one aspect, the method includes forming a mixture of non-wood fibers and exposing the mixture to a brightening agent to produce brightened fibers. The brightening agent is oxygen gas, peracetic acid, a peroxide compound, or a combination thereof. The brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.

Abstract: The present invention is directed to a method of increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers and exposing the mixture to a brightening agent, the brightening agent being a permanganate compound, an acid, or a combination of the permanganate compound and the acid. The resulting brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.

Abstract: This present invention relates to methods for preparing premium or near-premium brightness pulps for towel and tissue applications from fiber sources comprising substantial amounts of lignin-containing pulp and chemical pulp while controlling fines, scale and anionic trash. These methods use alkaline hydroxide in combination with peroxide and oxygen for initial bleaching stages followed by treatment with a peroxide activating agent to convert residual peroxide in the pulp into peracetic acid followed by a final reductive bleaching stage.
