tensile properties of polypropylene fibers

  • Effects of processing parameters and molecular weight

    The tensile properties of polypropylene fibers produced in a short‐spin line are correlated with the parameters of the three processing stages (spinning drawing and annealing) and with the molecular weight distribution In general tensile stiffness and strength increase with increasing molecular orientation while the elongation at break decreases The degree of orientation is
