Abstract: The present invention provides dye mixtures containing a dye of the formula (I) and a dye of the formulae (II) where Z is —CH?CH2 or —CH2CH2Z1 and Z1 is hydroxyl or an alkali-eliminable group; and M is hydrogen, an alkali metal or one equivalent of an alkaline earth metal. The invention also relates to a process for their preparation and their use.

Abstract: Provided is a novel method of dyeing a corespun yarn which comprises an inorganic fiber core and at least a first sheath. The method comprises: (a) contacting the corespun yarn with a dye liquor; (b) heating the dye liquor to a dyeing temperature for a time effective to dye the yarn; (c) cooling the dye liquor at a controlled rate; and (d) rinsing the yarn with water or with a mixture comprising the dye liquor and water. The dyed corespun yarn has a strength retention of about 80% or more based on the undyed yarn. The methods in accordance with the invention allow for the formation of uniformly dyed, high strength corespun yarns. Also provided is a dyed, corespun yarn which can be made by the inventive method, a fabric formed from the corespun yarn, as well as a product upholstered with the fabric. The dyed yarns exhibit substantially no “grin through” and little to no yarn strength loss after dyeing.

Abstract: Fiber-reactive monoazo and disazo dyes, suitable for dyeing cellulose material, such as cotton, and also synthetic or natural polyamide material, such as wool, in high color depth and with good fastness properties, are described which contain a quaternary ammonium group, such as a trialkylammonium group, and contain, as a fiber-reactive group, a group of the vinyl-sulfone series, or a grouping containing a group of the vinyl-sulfone series, or a heterocyclic fiber-reactive group selected from a halogeno-substituted pyrimidine or triazine.

Abstract: A fiber-reactive dye corresponding to formula (1) ##STR1## in which: Fb is the radical of an azo dye, of a heavy metal complex azo dye, of a formazan dye, of a triphenodioxazine dye or of a phthalocyanine dye;U.sup.(+) is a permanent quaternary ammonium group;A.sup.(-) is a colorless anion, andR.sup.x, R.sub.4, G, Q and n are as defined in the specification, with the proviso that the dye contains at least one group of the vinylsulfone series, such as a group of the formula --SO.sub.2 Y, wherein Y is as defined in the specification, these dyes being capable of dyeing hydroxy- and/or carboxamido-containing fibres, such as cellulosic fibre and wool.

Abstract: A fiber reactive dye having the formula ##STR1## wherein R.sub.1 and R.sub.3 are independently selected from the group consisting of; hydrogen; an alkyl group having from one to four carbon atoms; the foregoing alkyl group further substituted with one or more groups selected from hydroxy; amino; sulfo; halogen; an aryl radical; a heterocyclic radical or combination thereof; where for R.sub.3 said amino group maybe further substituted by a nitrogen heterocyclic fiber reactive group of the series: 1, 3, 5 mono or dichloro triazinyl; 1, 3, 5 mono or difluoro triazinyl; trichloropyrimidinyl; difluoropyrimidinyl; or monochlorodifluoro pyrimidinyl; where the nitrogen heterocycle may be further substituted by an: alkyl; or aryl amino group;wherein B is selected from the group consisting of a C.sub.2 to C.sub.4 alkyl chain; a substituted aryl or a heterocyclic radical;wherein X is selected from the group consisting of SO.sub.3 H; SO.sub.3 Na or a hydroxy group; and wherein Q.sub.1 and Q.sub.

Abstract: Novel sulfonated quinolone compounds used in the preparation of fiber reactive dyes having the formula: ##STR1## being N-alkyl substituted-4-hydroxy-6-sulfo-2-quinolone. The alkyl group bonded to the nitrogen in the quinolone has from 1 to 4 carbon atoms which may be further substituted by an hydroxy, amino, or sulfo group. The compounds of the invention may be prepared by the sulfonation of an N-alkyl substituted-4-hydroxy-2-quinolones, ##STR2## followed by selective desulfonation to yield the compounds of interest. New monoazo fiber reactive dyes having the formulas: ##STR3## and their metal complexes, may be prepared from these sulfonated compounds by the diazotization of an amine component, selected from an unsubstituted, or a substituted benzene or naphthalene compound, containing a fiber reactive group, and coupling the diazo component to the compounds of the invention.
