An approach to expedient selection of charge density of filter baffle plates for two-stage cleaning of spinning solution of viscose and other solutions of polymers is scrutinized. Use of the characteristics of variation of unit costs per unit volume of the filtered spinning solution as a function of charge density of the main filtration stage as a criterion of selection is validated. Because of universality of the used generalized equation of filtration and economic criterion (unit cost) for analysis and selection of solution of the set task, the elucidated approach to finding the expedient combination of charge density for multistage filtration has prospect for use in industrial production of viscose and other artificial fibers, yarns, and films. This approach could be useful also for other industries that use filtering equipment.

仔细研究了一种用于筛选粘胶纺丝溶液和其他聚合物溶液的二级过滤板的电荷密度的方法。验证了将过滤后的纺丝溶液每单位体积的单位成本的变化特性作为主要过滤阶段的装料密度的函数，以此作为选择标准。由于所使用的通用过滤方程式的通用性以及用于分析和选择设定任务的解决方案的经济标准（单位成本），为多级过滤找到电荷密度的权宜组合的阐明方法在工业生产中具有广阔的前景。粘胶纤维和其他人造纤维，纱线和薄膜。该方法对于使用过滤设备的其他行业也可能有用。
