一种应用于有色金属高纯度提取的滤布及其织造方法

Filter cloth applied to non-ferrous metal high-purity extraction and weaving method thereof

Abstract

The invention discloses filter cloth applied to non-ferrous metal high-purity extraction. The multifilament of the filter cloth adopts superfine denier porous polypropylene multifilament, the filter cloth is manufactured in a high-temperature instantaneous polymerization surface treatment process after the weaving of warps and wefts, the texture of the filter cloth is plain, twill, satin weave or any one of all multilayer fabric structures, and the high temperature range is 120-220 DEG C. The filter cloth takes full advantages of the superfine denier porous polypropylene multifilament such as fine single fibers and porous single-beam multifilament, high-temperature instantaneous polymerization surface treatment process is adopted, and the woven filter cloth has the characteristics of high interception precision, good filter cake stripping capacity, excellent acid and alkali resistance and better hydrophobicity. Meanwhile, the invention discloses a weaving method of the filter cloth.
本发明公开一种应用于有色金属高纯度提取的滤布,滤布的复丝采用超细旦数多孔丙纶复丝,该滤布由经线与纬线织造后经高温瞬时聚合表面处理工艺制成,滤布的纹理构造为平纹、斜纹、缎纹或所有多层织物结构中任一种,所述高温温度范围为120~220℃。本发明充分利用超细旦数多孔丙纶复丝单根纤维细、单束复丝孔数多的优点,采用高温瞬时聚合表面处理的工艺,织造的滤布具有高截留精度、良好的滤饼剥离性、优良的耐酸耐碱性、较好的疏水性的特点。本发明同时公开该滤布的织造方法。
