摘要:
Compositions and a process for dyeing and printing synthetic materials of polyacrylonitrile, polyamides, or polyesters which contain anionic groups which comprises using a treating composition for aforesaid materials which consists of an aqueous dispersion of a basic dyestuff salt and a polynuclear aromatic sulfonic acid whereby the fixing times are reduced and fast and level dyeings are produced.
R IS CH3 OR C2H5; R'' IS H OR -COR"; R" IS CH3,C2H5,OCH3 OR OC2H5; X IS 1 OR 2; AND Y IS 0, 1, 2 OR 3;
ARE DISCLOSED FOR DYEING HYDROPHOBIC FIBER MATEIALS, E.G. POLYESTER. THE DYEINGS ARE CHARACTERIZED BY GOOD FASTNESS TO ALKALINE BOILING AND GOOD FASTNESS TO SUBLIMATION.
摘要:
Process for dyeing synthetic fiber materials e.g. aromatic polyester, and fiber blends, e.g. blends of polyester with wool, in an aqueous solution at a pH of 4-6.5 at temperatures of about 98* to 140* C. with a quaternary nitrogen group containing dyestuff, said dyestuff being free of sulfonic and carboxylic acid groups.

R3-O-CH(-R7)-CH(-R6)-O-CH(-R5)-CH(-R4)-
R4, R5, R6 AND R7 ARE HYDROGENS OR LOWER ALKYL RADICALS WITH 1 TO 2 CARBONS; R3 IS HYDROGEN OR -COR8; R8 IS AN OPTIONALLY SUBSTITUTED LOWER ALKYL RADICAL; R2 IS CNH2N+1; AND N IS AN INTEGER FROM 1 TO 4. THE DYESTUFF ARE USEFUL FOR DYEING HYDROPHOBIC FIBERS, E.G. AROMATIC POLYESTERS.
摘要:
The invention comprises dyestuffs of the formula where F is an organic dyestuff radical, R is alkylene or cycloalkylene, R2 is alkylene, R1 is -S-or where X is hydrogen, an araliphatic or cycloaliphatic substituent or an aliphatic radical which may form part of a heterocyclic nitrogen-containing 5 or 6 membered ring, Y is a substituent which, upon treatment with alkaline substances and/or heat, may be split off as a negative ion leaving R2 with a positive charge, and n is a whole number. Organic dyestuffs specified are those of the azo, anthraquinone, triphenylmethane, oxazine or azaporphin series, and values specified for Y are the sulphuric acid ester, phosphoric acid ester and sulphonyloxy groups and halogen atoms. The dyestuffs are made by reacting a dyestuff sulphonic acid chloride or carboxylic acid chloride with an amine containing the group -R-R1-R2-Y, by esterifying dyestuffs of the above general formula but wherein the group Y is hydroxyl, or by synthesising the dyestuffs from dyestuff intermediates already containing the group -R-R1-R2-Y, for example by diazotisation and coupling in the case of azo dyestuffs. The dyestuffs dye and print textile materials of natural or regenerated cellulose in conjunction with an alkali and heat treatment, and wool and silk from a weakly alkaline or neutral medium to give a variety of shades. Reference has been directed by the Comptroller to Specifications 835,819 and 868,741.
