  • Patent number: 4931065
    Abstract: Reactive dyeings on textile materials containing cellulose fibers are aftertreated with aqueous solutions of benzylated resins which are obtainable(a) by condensation of methylamine and epichlorohydrin or(b) by heating triethanolamine and/or triisopropanolamine in the presence of acidic catalystsand have been reacted with from 0.25 to 1 mole of benzyl chloride per mole of amine in the condensate.The dyed textile materials aftertreated in this manner possess good wet fastness.

  • Patent number: 4239491
    Abstract: An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of(a) polyethylene oxide, a block copolymer of ethylene oxide and propylene oxide or an ether, ester or carbamate derivative thereof and(b) a polyoxyethylated amine.
