Abstract (en)
[origin: WO2013116066A1] A process for producing a microfiber product stream is provided comprising: (A) contacting cut multicomponent fibers having a length of less than 25 millimeters with a heated aqueous stream in a fiber opening zone to remove a portion of the water dispersible sulfopolyester to produce an opened microfiber slurry; wherein the heated aqueous stream is at a temperature of at least 40°C; and (B) routing the opened microfiber slurry to a primary solid liquid separation zone to produce the microfiber product stream and a first mother liquor stream; wherein the first mother liquor stream comprises water and the water dispersible sulfopolyester.
