Abstract:
The present invention provides a porous hollow fiber membrane that has both high strength and high pure water permeability, and that exhibits excellent thermal deformation resistance. The present invention is related to a porous hollow fiber membrane containing a fluororesin-based polymer, and a manufacturing method of the membrane comprises a drawing step and a relaxing step. The porous hollow fiber membrane is characterized in that: the molecular chain of the polymer is oriented in the longitudinal direction of the hollow fiber membrane; and at the same time internal distortion of oriented non-crystalline chains, which is disadvantageous in terms of entropy, is alleviated.

Claim (Index 1):
A porous hollow-fiber membrane comprising a fluororesin-based polymer,\n wherein the porous hollow-fiber membrane has a columnar texture oriented in a longitudinal direction of the porous hollow-fiber membrane, a stress at 5% elongation (F5 value) in the longitudinal direction at 80\u00b0 C. is 6.5 MPa or more, and the F5 value in the longitudinal direction at 121\u00b0 C. is 5.0 MPa or more.
