Abstract

A process for separating a first mother liquor stream is provided. The process comprises: separating a first mother liquor stream in a second solid liquid separation zone to produce a secondary wet cake stream and a second mother liquor stream; wherein the first mother liquor stream comprises water non-dispersible microfiber, water, and water dispersible sulfopolyester; wherein the second mother liquor stream comprises water and water dispersible sulfopolyester; and wherein the secondary wet cake stream comprises water non-dispersible polymer microfiber.
