Preparation and Characterization of Melt-Spun Poly( Acrylonitrile-Methylacrylate) Hollow Fiber

Abstract:

In this study, a 85/15 AN/MA copolymer (acrylonitrile – methylacrylate copolymer with feed ratio of 85/15 mol%) was synthesized by emulsion polymerization at 60 °C, and then the copolymer was used to produce hollow fiber (abbreviated as PAN hollow fiber )by melt spinning using a single screw extruder machine. The PAN hollow fiber was characterized by using Scanning Electron Microscope (SEM), Thermo-gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The hollow fiber of melt-spinning PAN with high hollow rate of 51.1% has a homogeneous wall and regular section. The hollow fiber is potentially used as raw materials to fabricate heat preservation fabric for comfort clothing.
