DE683201C - Process for the production of ice colors by the printing or padding process on animal fibers or on synthetic fibers made of cellulose or on mixtures of the two types of fiber - Google Patents

Description

A process for the production of ice colors to as printing or padding process on animal fibers or synthetic fibers composed of cellulose or mixtures of the two types of fibers from the French patent specification 783,655 discloses a process for the production of ice colors in the finished print on cotton, according to which the fiber with mixtures of Oxy compounds capable of coupling and alkalis or from alkali salts of such azo components, from diazotizable amines that are neither liquid, low-melting nor volatile, and printed or padded from alkali nitrites and, after drying, initially for diazotization of the amine by acid and then for coupling by acid-binding agents Fund is passed through.

It has now been found that this mode of operation can not only be used for printing the vegetable fiber, but also for printing animal fiber, such as wool or silk, or for printing on synthetic fibers made of cellulose, such as regenerated Cellulose, or for printing mixtures of the two types of fiber, such as fabrics animal fibers and rayon made from cellulose; is excellently suited.

Example i 278.3 parts of i-amino-2, 5-diethoxy-4- (4'-rhsthyl) -phenoxyacetylaminobenzene are mixed with 219 parts of 2 ', 3'-oxynaphthoylaminobenzene, 167.4 parts of sodium nitrite, 33.3 parts crystalline-chem sodium acetate and 2 parts of Na. triium hydroxide well mixed.

This mixture is sucked in with 25-alcohol, 4oCcm 30% sodium hydroxide solution, 40 ccm Turkish oil, 259 water and 47o g neutral starch thickener. Fabrics consisting of wool, silk or rayon made of cellulose or mixtures of these fibers are loaded with the printing paste prints, dried and placed between two zen, of which cie, one in a thickening,., consisting of 8oo parts tragacanth thickener #: ;; 6o / iooo, iooo parts of water, iooo parts by weight hydrochloric acid 2 ° B6 or Amei acid, immersed, quickly passed through a short time afterwards with a 5% water Sodium carbonate solution at 40 to 50 ° C treated, being a deep pure blue Coloring .developed. One rinses and treats delt in a soap bath at 9o ° C. Example 2 225.4 parts of 3, 2'-dimethyl-4-amino-i, i'-azo- benzene are mixed with 271 parts of 2 ', 3'-oxy- n2phthoylaminob.enzene, 207.4 parts of sodium nitrite, 43.8 parts of crystalline nutrient acetate and 2 parts of sodium hydroxide well mixed. 50g of this mixture are, as in the case of game. i indicated, pasted, on copper ammonia silk, and the loading printed goods are made ready. Man holds pure garnet print patterns. Example 3 2447 tea 4'-chloro-2-amino-i, i'-diphenyl- ether-4 # carbonsäwreäthylester with 2533 parts i- (2 ', 3'-oxynaphthoylamino) - 2-methoxyb, enzene, 173.8 parts of sodium nitrite, 26.2 parts of crystalline sodium acetate and 2 parts of sodium hydroxide mixed well.

I; . 70g of this mixture are pasted with 2.5 .. alcohol, 25g water, 40g Turkish red oil, 409 sodium hydroxide solution 36 ° B6, 3409 water, iog 40% formaldehyde solution and 470g neutral starch thickener. The printing paste is printed on wool or natural silk and the printed goods, as indicated in example i, are finished. Pure red print samples are obtained.

PATENT CLAIM: Process for the production of ice colors after printing or padding on animal fibers or. Cellulose or synthetic fibers Genniches of both types of fiber, characterized in that, the goods with mixtures from couplable oxy compounds and alkalis or from alkali salts of such Azo components, from diazutizable amines, which are neither liquid nor low-melting are still volatile, and made of alkali nitrites printed or padded and after drying first for diazotization of the amine by acid and then for coupling is passed through acid-binding agents.
