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.
Claims20
A method of producing a molded cellulose-containing article comprising:
- adding an emulsion or slurry to a cellulose fiber furnish, wherein said emulsion or slurry comprises one or more sucrose fatty acid esters and one or more carrier particles;
- draining the furnish through one or more meshes or screens;
- thermal forming the mixture into a product in a mold;
- and
- stripping the product from the mold,
- wherein said product exhibits water, oil, and/or grease resistance compared to a cellulose product not treated with said emulsion or slurry.
A composition comprising sucrose fatty acid ester particles containing one or more cargo materials.
