Loom processing of hollow fiber membranes

Hollow fiber membrane modules (33) are manufactured by weaving hollow fiber membranes (20) into a web (19) while the fibers still contain a residual amount of the organic liquids used in the extrusion of the fibers. The web once formed is then passed through a final solvent extraction stage (23), fo...

Beschreibung
Zusammenfassung:	Hollow fiber membrane modules (33) are manufactured by weaving hollow fiber membranes (20) into a web (19) while the fibers still contain a residual amount of the organic liquids used in the extrusion of the fibers. The web once formed is then passed through a final solvent extraction stage (23), followed by drying and heating (24) to fix the final form and permeation characteristics of the membranes, and finally rolling the web into a bundle (27) which forms the interior of the module. The hollow fibers are woven as fill in the web.
