  • Dyeing process
    Patent number: 5944852
    Abstract: Improved dyeing processes for yarn and fabric materials are described. Dye pattern definition on a textile material is enhanced by treating the fabric or the fibers from which it is made with a quaternary ammonium compound and by including in the dye composition a gum which will react with the quaternary ammonium compound to form a viscous gel. The gel minimizes migration of the dye prior to fixation of the dye, and therefore pattern definition is improved. Similar improvements can be obtained when space dyeing yarn that comprises fibers that have been so treated.

  • Fibers and textile materials having enhanced dyeability and finish compositions used thereon
    Patent number: 5830240
    Abstract: A fiber finish composition is described which enhances the dyeability of the fiber or textile materials made from the fiber. The finish composition includes an alkyl substituted quaternary ammonium cation and a barrier agent. An aqueous dispersion of the finish composition is the preferred method of applying the finish composition to fibers. Also included is an improved method of dyeing fibers and textile materials using the fiber finish composition.

  • Acrylonitrile dimerization process
    Patent number: 4841087
    Abstract: Acrylonitrile dimerization is improved by increasing the proportions of catalyst used in the reaction mixture.
    Type: Grant
    Filed: March 14, 1988
    Date of Patent: June 20, 1989
    Assignee: Monsanto Company

  • Dimerization process improvements
    Patent number: 4639539
    Abstract: Acrylonitrile is catalytically dimerized in the presence of an organic phosphorus (III) catalyst, an inert hydrocarbon reaction solvent and a non-interfering proton-donating solvent; and the dimerized product separated from the catalyst by extraction. In the extraction the dimerized product is preferably dissolved in an extraction solvent and removed from the catalyst phase preparation. In the instant invention, the extraction solvent is an amide, preferably formamide. The extraction solvent and proton-donating solvent may be identical.

  • Method of coating nylon and polyester fibers with water dispersible polyvinyl acetate and coating achieved therefrom
    Patent number: H1936
    Abstract: An aqueous, coatable, thermally condensable composition is disclosed. The coating is based on dispersions of vinyl acetate polymers in water. Uniquely, the coating can be advantageously used for both nylon and polyester yarns. The coated yarns exhibit performance equivalent to or better than coated yarns based on traditional compositions.
