    Melt spinning of polypropylene (PP) multifilaments yarns: effect of myrrh resin on multifilament yarns properties
    (Wydawnictwo Politechniki Łódzkiej, 2022) Bolskis, Evaldas; Adomavičiūtė, Erika; Griškonis, Egidijus
    Melt-spinning is the most widely used polymeric multifilament yarn production method. It’s easy to scale and it is highly productive. Using this method can be formed multifilament yarns with various functionalities, using additives. The aim of this research is to investigate the formation of melt-spun multifilament polypropylene (PP) yarns modified with 10% ethanolic myrrh resin extract. In this study, multifilament yarns were successfully formed from PP with a myrrh resin by melt-spinning at two different drawing ratios (1.5; 2.5). It was indicated that processing parameters have a significant influence on the multifilament linear density (tex), tenacity (cN/tex) and tensile strain (%). Modification of PP with ethanolic myrrh extract has a significant influence on the mechanical properties of the melt spun multifilament yarns.
