PROBLEM TO BE SOLVED: To provide a method for improving properties of cellulose-based articles, including water resistance, oil and grease resistance, wet and dry strength, or softness.SOLUTION: Cellulose fibers are incorporated with an aqueous dispersion comprising: one of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof; a polymeric stabilizing agent; and water. The incorporation comprises pre-treatment of a pulp of fibers, addition of a paper-making process to a wet end, treatment during or after forming a paper web, application during or after a drying stage of a paper-making process, and combinations thereof. 【課題】セルロース系物品の耐水性、耐油脂性、湿潤及び乾燥強度、または柔軟性を含む特性を改善する方法の提供。【解決手段】エチレン系熱可塑性ポリマー、プロピレン系熱可塑性ポリマー及びこれらの混合物の１種と、高分子安定剤と、水とから成る水性分散体を、セルロース繊維と添合させる。添合は、パルプ繊維の前処理、製紙プロセスのウェットエンドへの添加、ペーパーウェブの生成中または後の処理、製紙プロセスの乾燥工程中または後の塗布、及びこれらの組み合わせである。【選択図】なし
