Study on Lamellar Structures and Parameters of Polyethylene Hollow Fiber Membranes Made by Melt-Spinning and Stretching Method

Article Preview

Abstract:

Lamellas important for micropores were well formed during extrusion and annealing process in melt-spinning and stretching method. This unusual crystalline structure and its changing during annealing and stretching process were well studied in term of lamellar size, lamellar crystallite orientation, degree of lamellar and observation of morphology. Lamellar and microfibril model was accepted as mechanism of making micropore for this process. Gas permeability and porosity testing experimental were used to characterize membrane properties.
