  • The curling phenomenon of polypropylene yarns
    Demšar, Andrej, 1964- ; Sluga, Franci, 1948-2023
    Polypropylene is a thermoplastic polymer which, because of its intrinsic properties (it doesn't absorb water, it has low density, low thermal conductivity, good resistance to different chemicals, it ... doesn't irritate skin etc.), is penetrating new markets at the expense of other polymers. This is why there is a need in industry of polypropylene fibres for developing new products with new or better properties. In the research work on the polypropylene yarns the conditions for production of polypropylene fibres which crimp after drawing were established. The goal of research work was to investigate of spinnign temperature on the formation of crimps and the degree of crimp.
