A process for producing a microfiber product stream, the process comprising: (A) contacting short cut multicomponent fibers having a length of less than 25 millimeters with a heated aqueous stream in a mix zone to produce a short cut multicomponent fiber slurry; (B) routing the short cut multicomponent fiber slurry and optionally, a heated aqueous stream, to a fiber opening zone to remove a portion of the water dispersible sulfopolyester to produce an opened microfiber slurry; and (C) routing the opened microfiber slurry to a primary solid liquid separation zone to produce the microfiber product stream and a first mother liquor stream.
