| 为了解决现有技术中出现的由具有复丝的中空纤维膜中须毛或细毛造成的损坏问题，本发明提供了进一步改善的中空纤维膜，其中螺旋制备了使用单丝的稀松型管状编织物且所得编织物埋置在聚合物树脂中。该稀松型管状编织物的特征在于，该编织物由各个单丝以固定角度编织，以便形成菱形或方块形。该单丝在增塑的线缆上编织以形成上述编织物，用于上述中空纤维膜的聚合物涂料被涂布在该编织物上使得编织物埋置在聚合物中，然后涂料凝固。这里，增塑的线缆决定了中空纤维膜的内径。如上所述，其中埋置稀松型编织物的中空纤维膜在纵向可扩展（可扩张），在径向也可扩展，从而实现双轴扩展。也就是，上述中空纤维膜在径向以及纵向都是柔性的。由于径向的柔性，中空纤维膜可在较高的压力被反冲洗，而使用复丝制成的膜不行，使用复丝制成的膜在径向几乎不可扩展。因此，本发明的生产效率提高了。 | ||||||

| 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. | ||||||

| PURPOSE: A monofilament-reinforced hollow fiber membrane and a manufacturing method of the same are provided to prevent a tubular-shaped knitted product from being contaminated with permeated contaminants. CONSTITUTION: A hollow fiber membrane is a reinforced hollow fiber membrane. The inner diameter of the hollow fiber membrane is formed by embedding knitted shaped mono-filaments(12) into a tubular polymer film. A knitted product(10) is obtained. 6-24 mono-filaments of 25-250 deniers are spirally braided in the knitted product to ensure a rhomboid or diamond shaped-open region. The braided angle of the knitted product is maintained in a range between 20 and 60 degrees to the longitudinal direction. The thickness of the polymer film is in a range between 0.2 and 0.6mm. | ||||||
