  Abstract

The composite hollow fiber membrane is a ultra filtration made by coating a polymer mixture on the surface of the braid, which is a substrate. Compared to a single membrane, it has excellent strength, durability and life time. In this study, we tried to develop a heat treatment method to flatten the surface of the braid used as a fiber support for the composite hollow fiber membrane and improve the circularity of the cross section. A heat treatment device capable of controlling temperature and take-up speed was devised, and braids were heat treated with various conditions. As a result of comparing surface and cross-section images, it was observed that the surface of the specimen treated at 220 oC or higher was flattened by heat treatment and the cross-section became closer to a circular shape. And it was found that the lower take-up speed, the larger the diameter change due to heat shrinkage.
