Abstract

Abstract: In this work, the effect of five pigments on the mechanical and texturing properties of polypropylene BCF yarns has been investigated. The results showed that depending on the type, pigments may have a significant decreasing or increasing effect on the mechanical properties of polypropylene BCF yarns, although some of these differences may not be practically significant. As far as the bulk properties of the BCF yarns are concerned, a trend could not be established for the effect of pigments on crimp contraction and crimp modulus, but increasing the amount of pigments decreased the crimp stability of all BCF yarns. XRD and DSC analyses showed that the addition of pigments decreased the crystallinity index of the yarns depending on the type of pigment. DSC analysis showed a higher onset melting point after adding pigments with the exception of white one. FTIR spectra show no considerable reaction or interaction between polypropylene and the pigments employed in the masterbatch.
