PROPYLENPOLYMERFASER MIT HOHER FESTIGKEIT UND VERFAHREN ZUR HERSTELLUNG DERSELBEN |
摘要 |
<p>Process for the production of a high tenacity propylene polymer fiber which comprises: spinning fiber from a molten propylene polymer composition consisting essentially of an olefin polymer (I) and a high molecular weight propylene polymer (II) having a branching index less than 1 and melt strength from 5 to 40 cN; said propylene polymer (II) being present in a concentration from 0.1 to 10% by weight with respect to the total weight of the composition; and drawing the solid fiber thus obtained with a draw ratio greater than 4.5 when the spinning step is continuous and greater than 5 when the spinning step is discontinuous.</p> |
