| titleOfInvention | Process for producing on acetyl cellulose and linear polyamide and polyurethane fibres dyeings fast to cross-dyeing |
| abstract | Azoic dyeings, fast to cross-dyeing, are produced on acetyl cellulose, linear polyamide and polyurethane fibres by applying an aqueous solution containing a diazotizable base of the formula:- <FORM:0719287/IV(c)/1> in which the benzene ring a may be further substituted by alkyl, alkoxy or aryloxy groups or by halogen atoms and R1 and R2 are hydrogen or alkyl, aralkyl, aryl or hydroaromatic radicals with the exception that neither R1 nor R2 may be hydrogen if the group <FORM:0719287/IV(c)/2> is in ortho position to the amino group, and a coupling agent comprising an alkali metal compound of an arylamide of 2 : 3-hydroxynaphthoic acid which contains in the arylamide radical an alkoxy group either alone or together with other substituents such as halogen atoms or methyl or other alkoxy groups, effecting diazotization on the fibre and developing the dyestuff in a hot bath. In an example, cellulose acetate yarn is treated in an aqueous bath at 75 DEG C. containing 1-amino-2-ethoxybenzene-5-carboxylic acid-n-butylamide, the sodium salt of 1-(21:31-hydroxynaphthoylamino) - 2 - methyl - 4 methoxybenzene, diethanolamine, sodium chloride, ammonia and the condensation product obtained from oleic acid chloride and albumen decomposition products preferably lysalbic acid according to Specification 413,016, diazotization is then effected with acidified sodium nitrite solution and the dye is developed with hot aqueous ammoniacal sodium acetateoleymethyltaurine solution. Long lists of other suitable diazotizable bases and coupling components are given. Specification 463,062 also is referred to. |
