Abstract
Presently, for economic and technological concerns, production of blended fibers has attracted the attention of industrial technologists and academic researchers. The importance of blended fibers can be derived from its use in the various fields such as geotextiles, composites, and insulation. In this study, PP/LDPE blended filament yarns with blend ratios of 100/0, 99/1, 97/3, 95/5, 93/7, 90/10 were melt spun, drawn, and textured at temperatures of 110, 120,130,140 and 150°C. Tensile properties (except modulus) of the textured yarns spun from PP/LDPE blends were found to be higher than those of pure PP at most applied texturing temperatures. Crimp properties of samples were improved by increasing the texturing temperature. By increasing the LDPE fraction in samples, especially at 140°C and 150°C, however, lower crimp properties were observed.
