摘要： A hollow fiber membrane is made by covering a tubular supporting structure with a membrane dope and converting the membrane dope into a solid porous membrane wall. Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope. The reinforcing structure thereby becomes embedded in the membrane wall. The supporting structure may be soluble in a non-solvent of the membrane wall, for example water, and may be removed from the membrane. Alternatively, the supporting structure may be porous. A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.
摘要翻译：通过用膜涂料覆盖管状支撑结构并将膜涂料转化为固体多孔膜壁来制造中空纤维膜。可选地，可以在支撑结构覆盖涂料之前在支撑结构周围添加圆形编织物形式的织物增强结构。由此加强结构嵌入膜壁中。支撑结构可以溶解在膜壁的非溶剂中，例如水，并且可以从膜上除去。或者，支撑结构可以是多孔的。多孔支撑结构可以通过无纺织物工艺，在挤出机内的烧结工艺或通过挤出与第二组分混合的聚合物来制造。第二组分可以是可溶性固体或液体，超临界气体或不与第一聚合物反应的第二聚合物。

摘要： A filtering membrane has a supporting structure (12) comprising filaments (400, 410) and is coated with a dope to produce a polymeric membrane layer. Some or all of the filaments comprise a second polymer that is soluble or swellable in a solvent of the dope. The supporting structure may be braided with yarns. One or more yarns (400) may comprise filaments comprising the second polymer. In one example, a braided tubular support is coated with a dope based on PVDF in NMP. Some or all of the yarns of the braid are made of bi- component core- sheath PET -PVDF filaments. With as few as 4% of the yarns in the braid made of the bicomponent filaments, peel strength and pull force of the membrane is improved relative to a braid made entirely of PET yarns. In experimental examples, unpeelable composite membranes were produced. The membrane may be used, for example, for water or wastewater filtration applications.
摘要翻译：过滤膜具有包括细丝（400,410）的支撑结构（12），并且涂覆有涂料以产生聚合物膜层。长丝中的一些或全部包含在该涂料的溶剂中可溶或溶胀的第二聚合物。支撑结构可以用纱线编织。一根或多根纱线（400）可以包括包含第二聚合物的长丝。在一个示例中，编织管状支撑体涂覆有基于PVDF在NMP中的涂料。编织物的一些或所有纱线由双组分芯鞘PET -PVDF丝制成。在由双组分长丝制成的编织物中，只有4％的纱线相对于完全由PET纱线制成的编织物而提高了膜的剥离强度和拉力。在实验实施例中，制备了不可剥离的复合膜。膜可以用于例如水或废水过滤应用。

Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope. The reinforcing structure thereby becomes embedded in the membrane wall. The supporting structure may be soluble in a non-solvent of the membrane wall, for example water, and may be removed from the membrane. Alternatively, the supporting structure may be porous. A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.
