    • PURPOSE: Polyvinylalcohol microfibrillar fiber and a preparation method thereof are provided to reduce manufacturing processes through simple mechanical shearing manipulation using methanol as a saponification solvent. CONSTITUTION: A preparation method of polyvinylalcohol microfibrillar fiber includes a step for producing a solution by dissolving poly(vinyl pivalate/acetic acid vinyl) copolymers as a saponification solvent, and a step for shearing a mixed compound after agitating the solution and an alkali saponification solvent after injecting the alkali saponification solvent in the solution. The saponification solvent one organic solvent selected from methanol, tetrahydrofuran, acetone, methyl ethyl ketone or dioxane. The saponification solvent is comprised of hydroxide of 0.5 - 0.07 mole selected from a group consisting of potassium hydroxide, calcium hydroxide, sodium hydroxide, and their mixture and water of 0.1 - 0.8 mole.
    • 目的:提供聚乙烯醇微原纤维及其制备方法,通过使用甲醇作为皂化溶剂进行简单的机械剪切操作来减少制造过程。 构成:聚乙烯醇微原纤维纤维的制备方法包括通过溶解聚(新戊酸乙烯酯/乙酸乙烯酯)共聚物作为皂化溶剂来制备溶液的步骤,以及搅拌溶液和碱皂化溶剂之后剪切混合化合物的步骤 在溶液中注入碱皂化溶剂。 皂化溶剂一种有机溶剂,选自甲醇,四氢呋喃,丙酮,甲基乙基酮或二恶烷。 皂化溶剂由选自氢氧化钾,氢氧化钙,氢氧化钠及其混合物和水为0.1-0.8摩尔的0.5-0.07摩尔的氢氧化物组成。
