摘要: A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a “whiskering” problem common in prior art multifilament braid-supported tubular membranes. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable it can be infiltrated with membrane polymer which, when coagulated embeds the braid positioning it around the lumen. The spiral weave, free of any circumferentially constricting monofilament, when embedded in film, allows the membrane to be biaxially distensible. In other words, the membrane has “give” not only in the axial or longitudinal direction but also in the radial direction. “Give” in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.
摘要翻译: 通过仅嵌入具有单丝螺旋开口编织的编织物而形成中空纤维膜,以避免现有技术的复丝编织支撑的管状膜中常见的“晶须”问题。 开口织物的特征在于由单丝分隔的聚合物膜的连续的,圆周的,菱形的区域。 当编织物支撑在塑化PVA电缆上时,可以用膜聚合物渗透,当聚合物嵌入编织物将其定位在管腔周围时。 当嵌入膜中时,没有任何周向收缩的单丝的螺旋编织允许膜是双向扩张的。 换句话说,膜不仅在轴向或纵向上而且在径向方向上“给”。 在径向方向上“给”可以使污染的膜在比不能径向扩张的相似的编织物更高的压力下进行反冲洗。
