1. A PROCESS FOR EXHAUST DYEING FROM A SINGLE BATH A FIBROUS MATERIAL CONTAINING A MIXTURE OF CELLULOSE FIBERS AND POLYACRYLONITRILE FIBERS WITH A REACTIVE DYESTUFF HAVING AT LEAST ONE VINYLSULFONE REACTIVE GROUP OR ONE GROUP THAT FORMS A VINYLSULFONE REACTIVE GROUP IN ALKALINE MEDIUM AND WITH A NON-REACTIVE BASIC DYESTUFF, WHICH COMPRISES HEATING SAID MATERIAL AT A TEMPERATURE BETWEEN ABOUT 20*C AND ABOUT 80*C IN AN AQUEOUS DYEBATH THAT CONTAINS SAID REACTIVE DYESTUFF, A NON-IONIC DISPERSING AGENT AND AND ALKALINE AGENT TO ADJUST THE PH OF SAID DYEBATH TO BETWEEN ABOUT 9 AND ABOUT 12 UNTIL SAID REACTIVE DYESTUFF IS FIXED ON THE CELLULOSE FIBERS, ADDING TO SAID DUEBATH SAID NON-REACTIVE BASIC DYESTUFF AND A FREE ORGANIC ACID OR INORGANIC ACID TO ADJUST THE PH OF SAID DYEBATH TO BETWEEN ABOUT 3.5 AND ABOUT 6, AND HEATING SAID MATERIAL IN SAID DYEBATH AT A TEMPERATURE BETWEEN ABOUT 95*C. AND ABOUT 130*C. UNTILS SAID BASIC DYESTUFF IS FIXED ON THE POLYACRYLONITRILE FIBERS.
摘要:
Process for the dyeing of mixtures of cellulose, linear polyester and polyacrylonitrile fibers with reactive dyestuffs of the vinylsulfone type, disperse and cationic dyestuffs, wherein the goods are treated with a bath containing alkalies, non-ionic dispersing agents, a reactive dyestuff and a disperse dyestuff at 20* to 80*C and wherein subsequently free acid and a cationic dyestuff are added and the dyeing is completed in an acid medium at 95* to 130*C. Compared with the hitherto used two- or threebath processes the process of the invention has the particular advantage of saving 25 to 50 percent of dyeing time.

A LIQUID DYE CARRIER COMPOSITION INCLUDING BY WEIGHT ABOUT 60 TO ABOUT 100% OF A NORMALLY LIQUID ALKYLATED BIPHENYL, ABOUT 40 TO 0% BIPHENYL AND ABOUT 5 TO ABOUT I/% OF ANIONIC AND/OR NONIONIC EMULSIFIERS BASED ON THE WEIGHT OF THE ALKYLATED BIPHENYL. THE LIQUID ALKYLATED BIPHENYL MAY BE EMPLOYED ALONE OR AS A LIQUID ISOMERIC MIXTURE IN A DYE BATH FOR DYEING POLYESTER FIBERS AND OTHER ARTICLES HAVING A SYNTHETIC POLYMER OR OTHER BASIS.
摘要:
A PROCESS FOR THE SIMULTANEOUS DYEING OR PRINTING OF TEXTILE FIBRE MIXTURES WITH CATIONIC AND ANIONIC DYESTUFF IS DISCLOSED EHIC COMPRISES IMPREGNATING OR PRINTING THE TEXTILE FIBRE MIXTURE, AT TEMPERATURES BELOW THE ABSORPTION TEMPERATURE OF THE DYESTUFFS, WITH AN OPTIONALLY THICKENED SOLUTION CONTAINING AT LEAST ONE CATIONIC AND AT LEAST ONE ANIONIC DYESTUFF, SUFFICIENT ACID AND BUFFER SALT FOR THE PURPOSE OF MAINTAINING A PH-VALUE OF THE SOLUTION OF BETWEEN 3 AND 7, AT LEAST 0.5 G./1. OF SULPHATED OR SULPHONATED COMPOUND AS ANION-ACTIVE AUXILIARY, AND AT LEAST 0.5 G./1. OF AN AMIDE OF ALIPHATIC MONOCARBOXYLIC ACIDS CONTAINING FROM 8 TO 20 CARBON ATOMS, OR OF MIXTURES OF SUCH FATTY ACIDS WITH PRIMARY OR SECONDARY AMINES CONTAINING AT LEAST ONE LOWER HYDROXYALKYL GROUP, AND/OR OF A WATERSOLUBLE CONDENSATION PRODUCT FROM 1 EQUIVALENT OF FATTY ACIDS HAVING FROM 8 TO 20 CARBON ATOMS OF FROM MIXTURES OF SUCH FATTY ACIDS WITH FROM 1 TO 3 EQUIVALENTS OF A DIAND/OR TRIALKANOLAMINE, AND, OPTIONALLY, FURTHER AUXILIARIES, AND FINISHING THE DYEING OR PRINT BY A MOIST HEAT TREATMENT. THEREBY, THE TEXTILE FIBRE MIXTURES ARE DYED OR PRINTED VERY EVENLY, IN ONE SHADE OR IN SEVERAL SHADES, WITH GOOD FASTNESS PROPERTIES AND WITHOUT THE SO-CALLED "SANDWICH-EFFECT."
摘要:
PROCESS FOR INCREASING THE DYESTUFF AFFINITY OF FIBRE MATERIALS OF NATURAL POLYAMIDES CONSISTING IN TREATING THE FIBRE MATERIALS WITH AN AQUEOUS BATH CONTAINING WATER-SOLUBLE POLYAMIDES WHICH HAVE BEEN OBTAINED BY REACTING ALIPHATIC POLYAMINES OF THE FORMULA H-(N(-R)-X)N-N(-R1)-H IN WHICH R AND R1, INDEPENDENTLY OF ONE ANOTHER, STAND FOR HYDROGEN, A C1-C5-ALKYL GROUP OR A HYDROXYALKYL GROUP WITH 1-3 CARBON ATOMS; X DENOTES A BIVALENT, OPTIONALLY SUBSTITUTED ALIPHATIC RADICAL WITH 1-6 CARBON ATOMS; AND N STANDS FOR AN INTEGER FROM 1 TO 4, WITH A,B-UNSATURATED ALIPHATIC MONOCARBOXYLIC ACIDS, OR WITH ALIPHATIC POLYCARBOXYLIC ACIDS WHICH MAY CONTAIN HERETO ATOMS, OR WITH THEIR FUNCTIONAL DERIVATIVES CAPABLE OF FORMING AMIDES.
摘要:
Stable, concentrated, aqueous solutions of basic oxazine dyestuffs of the formula IN WHICH R'' and R'''' represent lower alkyl groups, R1 and R2 represent hydrogen atoms or lower alkyl groups or phenyl unsubstituted or substituted in the benzene nucleus by methyl, methoxy or ethoxy groups, R3 represents hydrogen or methyl, and X represents a halogen ion, consisting essentially of (a) the hydrochlorides of the said oxazine dyestuffs and (b) high molecular polyglycols in an amount of about 2 to about 20 percent by weight calculated on the weight of the dyestuff.
