ULTRAFILTRATION PROCESS FOR PRODUCING A SULFOPOLYESTER CONCENTRATE

Eastman Chemical Company,...

1. A process for recovering a primary polymer concentrate stream, said process comprising:
(A) contacting cut multicomponent fibers having a length of less than 25 millimeters with a treated aqueous stream in a fiber
slurry zone to produce a cut multicomponent fiber slurry; wherein said cut multicomponent fibers comprise at least one water
dispersible sulfopolyester and at least one water non-dispersible synthetic polymer immiscible with said water dispersible
sulfopolyester; and wherein said treated aqueous stream is at a temperature of less than 40° C.;

(B) contacting said cut multicomponent fiber slurry with a heated aqueous stream in a mix zone to produce a heated multicomponent
fiber slurry;

(C) routing said heated multicomponent fiber slurry to a fiber opening zone to remove a portion of said water dispersible
sulfopolyester to produce an opened microfiber slurry;

(D) routing said opened microfiber slurry to a primary solid liquid separation zone to produce said microfiber product stream
and a first mother liquor stream; wherein said first mother liquor stream comprises water and said water dispersible sulfopolyester;

(E) routing at least a portion of said first mother liquor stream to a second solid liquid separation zone to produce a secondary
wet cake stream and a second mother liquor stream; wherein said second mother liquor stream comprises water and water dispersible
sulfopolyester; and wherein said secondary wet cake stream comprises microfiber; and

(F) routing said second mother liquor stream to a primary concentration zone to remove water from said second mother liquor
stream to produce said primary polymer concentrate stream; wherein said primary concentration zone comprises at least one
ultrafiltration membrane.
