Abstract：

The study on the test method forelastic stage oftensile process of hollow fiber membrane was carried out. by setting different stretching range of samples, measuring the recovery aftertension, processing the force and elongation of the specified non proportional extension strength, ultimately determine elastic stage and whether the performance of sample was changed.
