Abstract: The process for dyeing leather by the exhaust method comprises allowing a pigment dispersion and an aqueous solution of sulfur dye to act on the conventionally pretreated leather in one step or in succession. It affords a high depth of shade and a high brilliance which are not achieved by using the pigment or the sulfur dye on its own.

Abstract: A process for applying a reactive dye to a cellulosic substrate comprising:(a) adding one or more dyeing assistants selected from the condensation product of sulphonated diphenyl ethers, condensation product of sulphonated ditolyl ethers, condensation products of polydiphenylsulphones with formaldehyde and condensation products of polyditolyl sulphones with formaldehyde (and salts thereof) into an aqueous liquor, optionally together with a salt (hereinafter defined as Process Step a);(b) introducing the substrate into the dyebath and adding one or more reactive dyes, (hereinafter defined as Process Step b) ; and(c) fixing the dyestuff onto the substrate (hereinafter defined as Process Step c).
Abstract: The invention relates to a process for fixing dyes which contain at least one polymerisable double bond and/or at least one polymerisable ring system on moist fibre material using ionising radiation together with at least one colorless compound which contains at least one polymerisable double bond, but not N-C.sub.1 -C.sub.4 alkylolacrylamide or N,N-di(C.sub.1 -C.sub.4 alkylol)acrylamide.
Abstract: Cellulose fibers are dyed ecologically soundly with sulfur black dyes by the pad-dyeing process by avoiding sulfides as reducing agent by replacing them by a dithionite-based mixture with at least one reducing sugar. A high color yield, a deep black shade and good reproducibility are ensured. The preferred reducing sugar is glucose.
Abstract: A method of dyeing textile webs with reactive dyestuffs in which the dyestuff and alkali solutions are applied successively to the web separately and directly following one another in predetermined proportions to the dry weight of the web in a single machine pass.

Abstract: A process for the dyeing of a fibrous article containing fibers of a polyamide polymer with an anionic dye and dyed products made by the process. The process includes immersing the article in a dyeing bath of a liquid solvent for the anionic dye. The liquid solvent and the article are heated to a temperature at least equal to the dyeing transition temperature of the fiber of polyamide polymer. The anionic dye is added to the dyeing bath as a miscible liquid concentrate at a dye addition rate during a controlled dye addition period. At least a portion of the dye is added while the solvent and the article are at a temperature at least equal to the dyeing transition temperature.
Abstract: This invention relates to improved methods and compositions to enhance stain resistance of carpet fiber. The improved methods relate to a continuous aftertreatment for dyed carpet fabric and to two-step processes, either batch-batch, batch-continuous or continuous-continuous. The improved compositions are used in the processes to enhance stain resistance of carpet or carpet fiber and to overcome various prior drawbacks, such as, yellowing, oxidation and durability to cleaning. The sulfonated aromatic condensates are used to enhance stain resistance, and can be combined with fluorocarbon compounds for soil resistance, thiocyanates, and/or salts having divalent cations, such as magnesium sulfate. Also various dispersing agents, buffering acids and sequestering agents are disclosed.
