PROCEDE D'OBTENTION DE TEINTES SOLIDES, A LA SURTEINTURE SUR RAYONNE D'ACETATE.
On emploie des fils d'effet de rayonne d'acétate, solides à la surteinture, dans des étoffes de laine ou de mélanges de laine et de fibran- ne pour vêtements.
Le nombre des colorants qui résistent à la surteinture usuelle pour ces articles est minime, surtout quand il s'agit d'obtenir des nuancesallant du rouge au bordeaux, spécialement lorsqu'on recherche une bonne solidité à la lumière.
Or, les Demandeurs ont trouvé qu'on obtenait des teintures extr- mement solides sur rayonne d'acétate, quand on traite celle-ci dans des bains aqueux ammoniacaux contenant des solvants organiques, à faible réaction alca- line, comme par exemple les mono-éthanolamine et di-éthano lamine et des mélan- ges de l-amino-2.5-dimétboxy 4-nitrobenzène avec des sels alcalins du 1-(2'.

1,2 kg d'un produit de condensation obtenu à partir d'acides gras à poids moléculaire élevé et de produits de dégradation d'albumines,
300 cm3 d'ammoniaque à 25% et
3 kg de chlorure de sodium, on rince et on diazote pendant 30 minutes dans 300 litres d'eau froide avec
300 g de nitrite de sodium et
1,5 1 d'acide chlorhydrique à 20 Bé,
après quoi on procède au traitement ultérieur à 60 dans
300 litres d'eau additionnée de
300 g d'acétate de sodium. On rince et l'on obtient une teinture rouge tirant sur le bleu; cette teinture est solide à la surteinture.
Si, dans l'exemple précédent, on utilise un mélange composé de
EMI2.1
1-amino-2.5-diméthoxy-±-nitrobenzène et de 1-(2'-hyàroxy-carbazol-3'-car Do- nylamino)-4-chlorobenzèné, on obtient une teinture pourprée, solide à la sur- teinture.
EMI2.2
Si, à la place du 1-(2'3'-hydroxy-naphtoylamino) -2-méthoxybenzène, on emploie le 1-(z.3'-hydro-naphtoylamina) 2 méthyl lnéthoybenzène, on ob- tient un bordeaux.

PROCESS FOR OBTAINING SOLID COLORS, BY OVER-TINT ON ACETATE RAYON.
Acetate rayon-effect yarns, which are solid to over-dyeing, are used in woolen fabrics or wool-fiber blends for clothing.
The number of colorants which resist the overdyeing customary for these articles is minimal, especially when it comes to obtaining shades ranging from red to burgundy, especially when good lightfastness is desired.
However, the Applicants have found that extremely solid dyes are obtained on acetate rayon, when the latter is treated in aqueous ammoniacal baths containing organic solvents with a weak alkaline reaction, such as, for example, mono -ethanolamine and di-ethanolamine and mixtures of 1-amino-2.5-dimetboxy 4-nitrobenzene with alkali salts of 1- (2 '.

10 kg of acetate rayon are treated for 90 minutes in 300 liters of water at 75 with a mixture of

<Desc / Clms Page number 2>
230 g of water and then introduced into
300 1 of water at 75 container
1.2 kg of a condensation product obtained from fatty acids with high molecular weight and degradation products of albumins,
300 cm3 of 25% ammonia and
3 kg of sodium chloride, rinsed and nitrogenated for 30 minutes in 300 liters of cold water with
300 g of sodium nitrite and
1.5 1 hydrochloric acid at 20 Bé,
after which the further processing is carried out at 60 in
300 liters of water with
300 g of sodium acetate. It is rinsed and a red dye is obtained drawing on blue; this dye is solid to over dyeing.
If, in the previous example, a mixture composed of
EMI2.1
1-amino-2.5-dimethoxy- ± -nitrobenzene and 1- (2'-hydroxy-carbazol-3'-car D-nylamino) -4-chlorobenzene, a purple tincture is obtained which is solid on over-dyeing.
EMI2.2
If, instead of 1- (2'3'-hydroxy-naphthoylamino) -2-methoxybenzene, 1- (z.3'-hydro-naphthoylamina) 2 methyl lnethoybenzene is used, a bordeaux color is obtained.
