    摘要: An improved composition for use as a dispersant in azo dye systems contaminated with soluble copper impurities comprising an amine lignosulfonate salt and ethylenediaminetetraacetic acid. Preferably, the ethylenediaminetetraacetic acid is employed in an amount of about 1 to about 4 moles per each molar amount of the copper present in the system, per 1,000 grams of the lignosulfonate. Also disclosed is an improved azo dye system containing an amine lignosulfonate salt and ethylenediaminetetraacetic acid, and an improved method of dyeing materials with copper-contaminated dye systems containing azo dyestuffs and lignosulfonate salts wherein the azo dye reduction effect is alleviated by utilizing as the lignosulfonate salt an amine salt thereof, together with ethylenediaminetetraacetic acid.

    摘要: Disclosed herein is an improved process for producing sulfonated lignin surfactants for use as dispersants for disperse dyes and vat dyes. The improved process is to react a sulfonated lignin and epihalohydrin under certain conditions to block a portion of the free-phenolic hydroxyl group and at the same time cross-link the lignin molecules to increase the molecular weight. Another aspect of the process of this invention is to oxidize the thus treated lignin to stabilize its properties. Dispersants made according to this process have improved fiber staining and heat stability properties over other lignin-based dispersants.

    摘要: Improved dyestuff compositions comprising a dye cake and a dye dispersant are disclosed wherein the dye dispersant comprises sulfonated or sulfomethylated lignin of increased activity and improved heat stability properties and which dispersants are disclosed to be prepared by substantial removal of the low molecular weight component of the sulfonated and sulfomethylated lignin. Exclusion of the low molecular weight portion of the dispersant may be accomplished by fractionation of the sulfonated or sulfomethylated lignin to remove a substantial portion of the molecules having a molecular weight below 3,000. Alternatively, in the case of lignin recovered from sulfate or soda wood pulping processes, the lignin may be fractionated to remove a substantial portion of the molecules having a molecular weight below 3,000 prior to sulfonation or sulfomethylation.

    摘要: A process for preparing sulfonated lignins suitable for use as dispersants and additives in dye compositions wherein sulfonated lignins are post-sulfonation crosslinked with a crosslinking agent of the aldehyde, epoxide, or polyhalide type at a pH range of between about 6.1 to 9 to selectively crosslink low molecular weight sizes of the sulfonated lignins to provide improved heat stability and dispersibility of the sulfonated lignins in dye compositions. The invention also concerns disperse and vat dye compositions, and printing gels, containing the sulfonated lignins as a dispersing agent or additive.

    摘要: Improved sulfonated lignin surfactants are provided for use as dispersants in dyestuffs. The process for providing the improved surfactants relates to using metals and borate salts to react with the azo dye reducing dihydroxy functions of the lignin molecule through chelation and ester formation mechanisms thereby inhibiting the lignin's azo dye reducing characteristics.

    摘要: Disclosed herein are cross-linked lignin gels which have been found useful as pesticide carriers in controlled release pesticide systems. The carrier is a highly reswellable cross-linked lignin gel prepared by reacting alkali lignin with from 1 mole to 10 moles of cross-linking agent, such as formaldehyde, per 1,000 grams of lignin. An aqueous solution of lignin and the cross-linking agent is reacted at elevated temperatures until cross-linking occurs to the point where a discernible increase in viscosity takes place and the gel is formed. The gels are allowed to dehydrate, and the pesticide in an amount from 0.1:1.0 to 2:1 (pesticide to carrier) is included by reswelling the dehydrated gel in an aqueous solution of the pesticide.

    摘要: A dyestuff filler material with humectant properties derived from kraft black liquor is disclosed. The process for obtaining the dyestuff filler material involves the acidification of kraft black liquor followed by separation of the precipitated portion, such as by filtration. The filtrate from this separation is then treated to solubilize the remaining portion of lignin, which primarily is low molecular weight lignin. This step is followed by a stabilization step, for example, with air to oxidize the filler material to minimize azo dye reduction.
