Patents by Inventor Samantha C. Ackerly

Samantha C. Ackerly has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20250146219
    Abstract: Disclosed are non-wood pulps having a fiber length greater than about 1.70 mm and a brightness of about 80% or greater. The relatively high degree of brightness is achieved without a loss fiber length or pulp yield. The high degree of brightness and relatively long fiber length makes the pulps well suited for the manufacture of wet-laid fibrous products, particularly wet-laid tissue products. The pulps may be prepared from plants of the family Asparagaceae by mechanical pulping and more preferably by a chemi-mechanical pulping using a sodium hydroxide alkaline peroxide solution where the primary pulp is cleaned to reduce debris prior to bleaching. Preferably the cleaned primary pulp has less than about 5% debris prior to bleaching.

  • Publication number: 20250116065
    Abstract: Disclosed are non-wood pulps having a fiber length greater than about 1.70 mm and a Very Long Fiber (VLF) content of about 0.50% or less. The fibers are readily dispersible in water and useful in the formation of fibrous sheets, particularly wet-laid sheets and more particularly wet-laid tissue sheets having a relatively low basis weight. In addition of having a relatively long fiber length and a low VLF content, the pulps may also have a Dispersivity Index of about 2.00 or less, which is indicative of a relatively narrow fiber length distribution. The pulps may be prepared from plants of the family Asparagaceae by mechanical pulping and more preferably by a chemi-mechanical pulping process using an alkaline and hydrogen peroxide where the plant biomass is cut to size prior to pulping.
