PROCEDIMENTO PER LA PREPARAZIONE DI FIBRE CAVE MICROPOROSE |
摘要 |
The present invention provides a process for preparing microporous hollow fibers by solvent stretching a non-porous hollow precursor fiber having a controlled degree of molecular orientation as measured by birefringence. Control of the precursor fiber orientation, yields a microporous hollow fiber having an improved balance of mechanical strength and permeability. |
