  "Procédé pour teindre des fibres mixtes de

  
laine et de cellulose régénérée et le matériel teint par ce procédé" La présente invention est relative à un procédé pour.  teindre des fibres mixtes de laine et de cellulose régénérée, et aux fibres teintes par ce procédé.

2-hydroxynaphtalène-3-carboxylique qui sont dérivées de diamines aromatiques ou de monoamines polycycliques, et en les développant sur les fibres ainsi traitées avec des composés diazoiques domines aromatiques pour former des colorants azoiques.

  
Des arylamides de l'espèce indiquée sont des produits de

Ces arylamides de l'acide 6-sulfo-2-hydroxynaphtalène3-carboxylique sont facilement solubles dans les solutions aqueuses d'alcalis faibles, par exemple de carbonates de métal alcalin, d'ammoniaque et de composés similaires. A partir de telles solutions, les arylamides montent uniformément sur la laine et la cellulose régénérée.

lange à cause de la faible alcalinité des solutions. Le développement des colorants sur la fibre s'effectue à la manière habituelle au moyen d'amines aromatiques diazotées. On obtient par ce procédé des teintes de nuances unies allant de l'orangé au noir, qui se distinguent généralement par une bonne solidité à l'eau, au frottement

  "Process for dyeing mixed fibers of

  
wool and regenerated cellulose and material dyed by this process "The present invention relates to a process for dyeing mixed fibers of wool and regenerated cellulose, and to fibers dyed by this process.

  
It has been found that mixed fibers of wool and regenerated cellulose can be dyed in solid shades by applying

  
 <EMI ID = 1.1>

  
2-hydroxynaphthalene-3-carboxylic compounds which are derived from aromatic diamines or polycyclic monoamines, and developing them on the fibers thus treated with diazo compounds aromatic domes to form azo dyes.

  
Arylamides of the species indicated are products of

  
 <EMI ID = 2.1>

  
with, for example, diamino compounds of benzene and mono- and diamines of diphenyl, diphenyl ether, diphenylamine, naphthalene, fluorene, carbazol, diphenylene oxide, benzothiazol etc.

  
These 6-sulfo-2-hydroxynaphthalene 3-carboxylic acid arylamides are readily soluble in aqueous solutions of weak alkalis, for example, alkali metal carbonates, ammonia and the like. From such solutions, arylamides rise evenly on wool and regenerated cellulose.

  
 <EMI ID = 3.1>

  
lange because of the low alkalinity of the solutions. The development of the dyes on the fiber takes place in the usual manner by means of diazotized aromatic amines. This process produces solid shades of shades ranging from orange to black, which are generally distinguished by good resistance to water, to rubbing.

carboylamino) -diphenyl (dissolved at boiling temperature with 0.3 parts by weight of sodium carbonate per 1 part by weight of "naphthol") and 20 g of sodium sulfate (bath volume 1:20). After stamping, the material is expressed and cold developed from the-

  
 <EMI ID = 7.1>

  
of 2.5-dichloroaniline.

  
The developed shade is further processed for
