    Abstract: A process for producing a microfiber product stream, the process comprises: (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; (B) contacting the cut multicomponent fiber slurry with a heated aqueous stream in a mix zone to produce a heated multicomponent fiber slurry; (C) routing the heated multicomponent fiber slurry to a fiber opening zone to remove a portion of the water dispersible sulfopolyester to produce an opened microfiber slurry; wherein the opening zone comprises a pipe reactor; and (D) routing the opened microfiber slurry to a primary solid liquid separation zone to produce the microfiber product stream and a first mother liquor stream.

    Abstract: A process for the manufacture of paper, board or similar products, comprises first of all, adding, to the paper pulp fibrous suspension, at least one main retention aid composed of a cationic (co)polymer. Then optionally the flocs obtained are sheared. Subsequently there is added to the suspension, separately or as a mixture, in any order: at least one secondary retention aid chosen from the group consisting of silica derivatives and anionic or amphoteric organic polymers, and at least one tertiary retention aid composed of a crosslinked anionic organic polymer with a size of greater than or equal to 1 micrometer and exhibiting an intrinsic viscosity of less than 3 dl/g.

    Abstract: The present invention provides a process for the manufacture of paper or board in which the anionic charge at the fibre surface is artificially increased by adding a substantive water soluble anionic compound, providing more sites and enhancing the adsorption of cationic papermaking additives. The preferred anionic compound is a phenolic polymer.

    Abstract: Polymeric materials and methods for making the polymeric materials utilizing bisphenolic stillbottoms, lignosulfonates, or both are disclosed. In one embodiment, a polymer is provided that includes a condensate of bisphenolic stillbottoms, an optional phenolic compound independent of bisphenolic stillbottoms, an aldehyde, and a lignosulfonate compound. The condensate may further include an amino compound, a catalyst, or combinations thereof. Alternatively, the polymer may be free of a phenolic compound independent of bisphenolic stillbottoms. The polymers may be used in the manufacture of articles including composites, laminates and paper products.
