3A3_0108_ WET SPUN COMPOSITE FIBRES WITH ENHANCED THERMAL AND MOISTURE PROPERTIES BY INCORPORATING WASTE ALPACA POWDER

Abstract

We have investigated a sustainable approach to enhance both the thermal and moisture properties of the wet-spun polyacrylonitrile by using green natural alpaca fibre. The waste alpaca fibres were mechanically milled into powders and mixed with various weight ratios of polyacrylonitrile (PAN) polymer in dimethyl sulfoxide (DMSO). The Differential Scanning Calorimetry (DSC) and the Thermogravimetric analysis (TGA) revealed improved thermal stability of the composite alpaca/PAN fibres than the control PAN. Moreover, owing to the addition of alpaca the moisture properties of the composite fibres were increased substantially.
