The melt spinning process is a simple, convenient and economic method for polymer fiber manufacturing at industrial scales. The fibres in our study are fabricated using an in-house built fibre spinning tower developed by IIUM Engineering student. The lab scale spinning tower has the capacity to melt materials up to 200 deg C and is able to spin up to 400 rpm. Schematic of the melt spinning process is shown below.
In our lab, the polymer blend used are normally prepared either by solvent cast or melt blending process. The polymer blends are then shredded into smaller pieces and melted in the crucible. The heat provided by the external heater at the lower end of the crucible is used to melt the polymer blend to a suitable viscosity that will allow the melt to flow through an orifice located at the bottom of the crucible.
