A high strength, non-woven fibrous material is prepared by (a) mixing an aqueous slurry of a negatively charged, water-insoluble natural or synthetic fiber or blend of fibers with an amount up to the fiber charge reversal point of a structured particle latex having pH independent cationic charges bound at or near the particle surface to form an aqueous suspension, (b) draining water from the aqueous suspension to form a wet web (c) wet pressing the web and (d) drying the web by heating.
一种高强度无纺纤维材料的制备方法是:(a) 将带负电荷、不溶于
水的天然纤维或合成纤维或纤维混合物的
水性浆料与一定量的结构化颗粒胶乳(其具有与 pH 值无关的阳离子电荷,结合在颗粒表面或其附近)混合,形成
水性悬浮液;(b) 将
水性悬浮液中的
水排出,形成湿网;(c) 对湿网进行湿压;(d) 对湿网进行加热干燥。
