Abstract:
A process for recovering a concentrated sulfopolyester dispersion is provided comprising routing an aqueous dispersion comprising a water-dispersible sulfopolyester to a sulfopolyester concentration zone to remove water from the aqueous dispersion to produce the concentrated sulfopolyester dispersion and a recovered water stream; wherein the sulfopolyester concentration zone comprises at least one ultrafiltration membrane.
