Description
Patented Apr. 12, 1932 UNITED STATES PATENT OFFICE ANILINE WORKS, INC.,. OF NEW YORK,
N. Y., A CORPORATION OF DELAWARE UNIFORM DYEING OF VISGOSE The present invention relates to the uniform dyeing of viscose silk of different origin.
It is known that it is very difficult to obtain even shades in the dyeing of viscose of different origin, for example of knitted artifi cial silk.
According to the present invention these difliculties are overcome by dyeing viscose with azo dyestuffs of the general formula:
wherein R stands for the residue of any coupling component and R stands for a benzene nucleus which may be substituted by a sulphonic or 'carboxylic acid group, to which the azo group is attached in meta or para position to m, and m' stands for an azo or azoxy group.
The dyestuffs used for the purpose of my invention are obtainable by the combination of tetrazo compounds of mand p-azoxyaniline and substitution products thereof with any desired coupling components, or by couplin g the diazo compounds of 3- and ii-nitroaniline or substitution products thereof with any desired component and subsequent reduction of the resulting monoazo dyestuffs with alkaline reducing agents, for example, grape sugar in alkaline solution, to the disazo-azoxy dyestuffs or trisazo dyestuffs.
The dyeing is carried out in the usual man nor as outlined in the examples, by dissolving the dyestuffs in hot water and adding to the dye-bath Glaubers salt and monopol soap (a water soluble salt of sulfonated castor oil) if desired with the addition of a wetting agent, f. i. an. alkyl-naphthalene-sulfonio acid, such as isobutyl-naphthalene-disulfonic acid. The viscose is introduced into the bath at about 30 G., then the bath is slowly heated to about 80 (3., at which temperature the viscose is dyed for about 4 to 1 hour. Then the viscose is washed and dried.
The dyeings thus obtained are distinguished by their uniformity.
No Drawing. Application filed February 9, 1929, Serial No. 338,891, and in Germany February 17, 19 28.
The invention is illustrated by the following examples, without being limited thereto:
Emample 1.-10 kgs. of knitted viscose are dyed in 300 liters of water. are added 200 gms. of the dyestuff, obtained by coupling the diazo compound of 4-nitraniline-2-sulfonic acid with 2-naphthylaminesulfonic acid and linking two molecules of the resulting monoazo dyestuff by treatment with alkaline reducing agents; 200 gms. of monopol soap (a water soluble salt of sulfonated castor oil and 2 kgs. of Glaubers salt are added. yeing is effected for one hour at about 80 C. and is followed by rinsing" and drying. The fabric is dyed uniformly a reddish blue shade.
Example 2.The dye-bath is prepared with 200 gms. of the dyestuif, obtained by coupling the diazo compound of 3-nitraniline with 2-naphthol-S-monosulfonic acid and linking two molecules of the resulting monoazo dyestuff by treatment with alkaline reducing agents, in 300 liters of water. 10 kgs. of knitted viscose are introduced into the dye-bath, which is then heated, 200 gms. of monopole soap and 2 kgs. of Glaubers salt are added, and the dyeing is completed within an hour at about 80 C. The fabric is dyed a uniform orange.
Example '3.10kgs. of knitted viscose are dyed in 300 liters of water. To the dye-bath are added 200 gms. of the dyestuif, obtained by coupling the diazo compound of 4-nitraniline-Q-sulfonic acid with phenol, methylating the hydroxy group of the monoazo dyestuff and linking two molecules of the resulting monoazo dyestufi' by treatment with grape sugar in alkaline solution to the corresponding disazo-azoxy dyestufl, having probable the formula:
SOaH SOaH 200 gms. of monopol soap and 2 kgs. of Glaubers' salt are added. Dyeing-is efl'ected for one hour at about 80 C. and is followed by rinsing and drying. The fabric is dyed uniformly a gold orange shade.
