Abstract: Disclosed are multicomponent fibers derived from a blend of a sulfopolyester with a water non-dispersible polymer wherein the as-spun denier is less than about 6 and wherein the water dispersible sulfopolyester exhibits a melt viscosity of less than 12,000 poise measured at 240° C. at a strain rate of 1 rad/sec, wherein the sulfopolyester comprising less than about 25 mole % of residues of at least one sulfomonomer, based on the total moles of diacid or diol residues, and wherein said poly(ethylene) terephthalate has an inherent viscosity of less than 0.55 dL/g. The multicomponent fiber is capable of being drawn at a relatively high fiber speed, particularly at least about 2000 m/min, and may be used to produce microdenier fibers. Fibrous articles may be produced from the multicomponent fibers and microdenier fibers. Also disclosed is a process for multicomponent fibers, nonwoven fabrics, and microdenier webs.

Abstract: Processes for the recovery of a sulfopolyester polymer from an aqueous dispersion and a sulfopolyester concentrate are provided. Particularly, a sulfopolyester concentrate, from which the sulfopolyester may be recovered and reused, are formed by processes such as evaporation and/or nanofiltration. Final recovery of the sulfopolyester may be achieved by further evaporation of water and/or salt precipitation. In addition, the recovered sulfopolyester and articles manufactured from the recovered sulfopolyester are also provided.
