More Information
Summary:The present invention relates to a method for the manufacture of synthetic fibers from a melt mixture of fiber forming matrix polymers, wherein at least one second amorphous additive polymer, which is immiscible with the fiber forming matrix polymer, is added to the fiber forming matrix polymers in a quantity of 0.05-5 wt % (with reference to the total weight of fiber forming matrix polymer and the additive copolymer). The additive polymer is obtained by multiple initiation. Furthermore, the present invention also relates to the synthetic fibers produced by the method.
