Effect of Post-Treatment on the Properties of Polypropylene Hollow Fiber Membrane
摘要
Abstract
Microporous polypropylene hollow fiber membranes were prepared by the melt-spinning and cold-stretching (MSCS) method. Mechanical properties of the hollow fibers were systematically studied. It was foundthat annealing condition and drawn ratio at the cold-stretching stage greatly affected on the porosity, average pore size, surface area per volume and penetration rate of this kind of membranes. Lamella and microfibril model was used to explain the formation mechanism of micro pores in this process.关键词
