Abstract
Superfine wool powder was blended and extruded with poly(propylene) (PP) to produce blend pellets, and the extruded pellets were hotβpressed into a blend film. SEM photographs show that the powder could be uniformly incorporated with PP after extrusion. FTβIR spectra shows that no substantial changes occurred in the chemical structure of both PP and wool powder in the blend film. XβRay diffraction analysis indicates that crystallinity of the blend film was much higher than that of the wool powder and little lower than that of PP. TGβtested results indicate that the thermal stability of the blend film declined with an increase in the powder content. Endothermic peaks of the wool powder in the blend film become more obvious as the powder content increases. Mechanical properties decline greatly with an increase in the wool powder content in the blend film.
