Hollow fiber (HF) membrane fabrication: A review on the effects of solution spinning conditions on morphology and performance

HF spinning is a potential configuration in membrane technology due to its self-supporting properties and high productivity per unit volume. The fabrication of HF membrane is affected by many parameters and it is important to explore the effect of these parameters on membrane properties. The amount of researches on traveling distance are minimal and inadequate to conclude their influence on fiber properties. The draw ratio has always been neglected (often taken as 1), cannot in most cases equal to 1 as it is influenced by take-up speed, dope flowrate and solution. Future insights on the above mentioned parameters are important. (C) 2018 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
