Abstract: The present disclosure describes methods of treating cellulosic materials with barrier coating compositions that allow for modifications of surfaces, including making such surfaces exhibit barrier functions such as oil and grease resistance, water resistance and the like. The methods as disclosed provide combining at least one saccharide fatty acid ester (SFAE) with polymers and applying such combinations on substrates including cellulose-based materials. Compositions comprising combinations of SFAE and polymers are also disclosed, including the use of such compositions to reduce blocking effects of said polymers without affecting the barrier performance or folding of articles of manufacture coated with said compositions. In addition, blocking ratings data for SFAE-polymer compositions may be used to identify conditions under which adhesive properties may be exploited to produce compositions that allow for effective heat sealing of articles of manufacture.

Abstract: The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.

Abstract: The present disclosure describes acyl halide liquid dispersions and tunable methods of treating cellulosic materials with compositions that provide increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for reacting acyl halides with and binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

Abstract: The present disclosure describes methods of treating fibrous cellulosic materials with sucrose fatty acid ester containing particles (carrier systems) that allow for modifications of surfaces, including making such surfaces water resistance and/or oil/grease resistance. The methods as disclosed provide combining at least one saccharide fatty acid esters (SFAE) with a polymer (e.g., latexes) to form micellular particles and applying such particles to substrates including fibrous cellulose-based materials (e.g., pulp) to form, inter alia, molded products. Compositions comprising combinations of SFAE, a latex and optionally a mineral or other additives are also disclosed.

Abstract: In general, the present invention is directed to a method of cooking wood in a cooking liquor medium. The method comprises a step of providing wood to a treatment vessel and contacting the wood with a digester additive composition. The composition comprises a first surfactant comprising an anionic surfactant, a derivative thereof, a salt thereof, or any combination thereof and a second surfactant comprising a polyoxyalkylene glycol or a derivative thereof. Additionally, according to another embodiment, the present invention is directed to a digester additive composition comprising a first surfactant comprising an anionic surfactant, a derivative thereof, a salt thereof, or any combination thereof and a second surfactant comprising a polyoxyalkylene glycol or a derivative thereof.

Abstract: In accordance with certain embodiments of the present disclosure, a method of decreasing the amount of oxidizer required by a pulping or papermaking process is provided. The method comprises adding to a process stream or solution of the pulping or papermaking process an effective amount of urea hydrochloride to reduce the amount of oxidizer required by the pulping or papermaking process.

Abstract: A process for cooking wood to pulp by contacting the wood with a deresinating agent containing fatty acid esters of polyoxyalkene glycols priors to cooking the wood with an alkaline liquor to simultaneously reduce pulp rejects and increase pulp yield.
