Abstract
Process for the preparation of fibers containing a uniform distribution of additives, whose additives, with respect to the processing of the fibers, are chosen from those that are soluble in water, volatile and reactive in said processing, characterized in that you understand (a) to prepare a polymer solution in a solvent for the polymer, said polymer including from about 5 to 30%, by weight, based on the total weight of said solution; (b) preparing a uniform dispersion of said additive with an inert organic compound which is insoluble in said polymer solution and in water with a boiling point above about 250ºC and a melting point below about 120º c, said solid additive being present in an amount of up to about 70% by weight, based on the total weight of said dispersion; (c) mixing said additive dispersion and said polymer solution, with high shear agitation, the amount of polymer in said mixture being at least 30% by weight, based on the total weight of polymer and solid additive in the same and (d) immediately wet spinning said mixture to form fibers.
