  • Publication number: 20230312819
    Abstract: A water dispersible sulfopolyester is provided wherein the sulfopolyester comprises: (a) residues of one or more dicarboxylic acids; (b) at least 4 mole percent and less than 8.5 mole percent of residues of at least one sulfomonomer; and (c) residues of one or more diols, wherein the sulfopolyester comprises a carboxylate ends to acid ends ratio of at least 0.6, wherein the sulfopolyester contains substantially equimolar proportions of acid moiety repeating units (100 mole percent) to hydroxy moiety repeating units (100 mole percent), and wherein all stated mole percentages are based on the total of all acid and hydroxy moiety repeating units being equal to 200 mole percent. Processes for producing the sulfopolyester are also provided as well as articles comprising the sulfopolyester.

  • Publication number: 20220298298
    Abstract: The present disclosure provides a process of recovering sulfopolyester comprising reduced impurity. Sulfopolyester is recovered from a composite material comprising water-dispersible sulfopolyester polymer and at least one non-water-dispersible polymer. The process includes washing the composite material comprising water-dispersible sulfopolyester with a solvent composition. The recovered sulfopolyester can be generated as a concentrated aqueous dispersion, a polymer melt, or a sulfopolyester solid.

  • Publication number: 20190309445
    Abstract: A multicomponent fiber having a shaped cross section is provided in this invention. The multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and wherein said water dispersible polymer is present at the perimeter of the outside cross-section of said multicomponent fiber in a proportion of not greater than 55% water dispersible polymer. Articles produced from the multicomponent fiber are also provided.

  • Publication number: 20190309447
    Abstract: A process for making a multicomponent fiber is disclosed. The process comprises extruding at least one water dispersible polymer to create a first polymer flow, extruding at least one water non-dispersible synthetic polymer to create a second polymer flow path, directing the resulting multiple polymer flows into a spinneret having a shaped cross section with a plurality of distribution flow paths, and combining the flow paths together to form a multicomponent fiber having a shaped cross section, wherein the multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein the domains are substantially isolated from each other by the water dispersible polymer intervening between the domains; and wherein the water dispersible polymer is present at the perimeter of the outside cross-section of the multicomponent fiber in a proportion of no greater than 55% water dispersible polymer.

  • Publication number: 20120094059
    Abstract: The present invention relates to a nylon yarn of a finely dispersed melt blended polymer alloy having i) a polyamide component selected from polyhexamethyleneadipamide, polycaprolactam and mixtures thereof, and ii) a nylon 11 component; wherein the polyamide component is the major component by weight of the total melt blended polymer and wherein the polyamide component has a viscosity of about 2.6 IV or more as measured in 96% sulfuric acid. The resulting nylon yarn shows improved bleach resistance. The present invention also relates to processes of producing the yarn and nylon carpets comprising the yarn described above.
