The present invention concerns the continous dyeing of synthetic textile fibres with a basic character.
Textile fibres consisting of synthetic polyamides are usually dyed either in aqueous solutions or dispersions of dyestuffs at the boiling temperature of the water or under pressure at temperatures between 100C. and 130C. or by foularding in an aqueous suspension of dyestuff followed by thermal fixation or steaming.
These processes have various disadvantages; In the case of the polyamides 11 they lead, for example, to dyeings which are not very deep, and in the case of texturised polyamides, they lead to uneven shades. Fur- The application of the solution of dyestuff to the textile material is preferably effected by impregnation and circulation, for example, in an apparatus of the wheeled vat type or in a William unit. The greater part of the excess solution may be eliminated by squeezing, for example by squeezing between two rollers and is preferably returned to the impregnating bath.
The textile material is then washed, either in the cold or hot, with a solvent or a mixture of solvents with a low boiling point, such as methanol, ethanol, isopropyl alcohol, acetone, methyl ethyl ketone, methylene chloride, or methyl or ethylacetate. These volatile solvents may be easily recovered and recycled.
ther, when water-insoluble plastosoluble dyestuffs are used, expensive grinding and dispersing operations are required in order to obtain these dyestuffs in a suitable form. v
In order to remove these disadvantages, it has been proposed to dye these fibres by impregnating with a solution of dyestuff in a mixture of alcohols and'halogenated hydrocarbon derivatives followed by a heat treatment. There are however great technical difficulties in the application of this process, especially in obtaining shades which are uniform and fast to rubbing.
It has also been proposed to dye with solutions of dyestuffs in non-volatile solvents and at elevated temperature; however, this technique, if used with the usual commercialdyestuffs, does not give satisfactory results, especially with regard-to the tinctorial yields and the fastness to wet treatments and to rubbing.
We have now found that excellent results are ob tained in the continuous dyeing of synthetic textile fibres having basic functions by passing these materials for a very short time from some seconds to some minutes, preferably between seconds and 2 minutes, at a temperature from 90C. to 160C. through a solution comprising an organic liquid with a boiling point from 120C. to 300C. and an anionic dyestuff in'the form of the free acid.
The synthetic textile fibres possessing basic functions to which the present process is applied may be for example, based on polyamides (condensation products of .hexamethylenediamine with adipic acid, polymerisation products of e-caprolactam, polycondensation products of amino-undecanoic acid and other analogous products), or based on polyurethanes. They may be in various forms such as fabrics, jersey, or yarns, and they may or may not be texturised.
The dyestuffs which may be used are those containing at least one free acid group not in salt form, such as for example a sulphonic or carboxylic acid group. Nonmetallise'd dyestuffs or metalliferous complexes of the 1/1 type or the 1/2 type possessing free acid groups may for example be used. The amounts of dyestuff to 6 be used depend upon the dyeing conditions and the shades required; they are only limited by the solubility of the dyestuffs in the bath.
Suitable organic liquids which boil at between 120C. and 300C. and which may be used as solvents for the dyestuffs are, for example, diols and triols such as ethylene glycol, propylene glycol, diethylene glycol and glycerine.
The present process enables colorations to be obtained in very short times which have penetrated well and are bright, resistant to rubbing and have a fastness to wet treatments and light at least equal to those obtained by the usual processes. It also enables the dyestuffs to be used in any physical form and the long grinding necessary to obtain some of them in a form suitable for their usual application to be avoided.
The invention is illustrated by, but not limited to, the following Examples in which the parts are parts by weight.
EXAMPLE 1 10 parts of the dyestuff C.I. Acid Blue 129 (Color Index No. 62058 in the form of the acid, are dissolved at about C. in 1000 parts of pure ethylene glycol. This solution is raised to a temperature of l 10C. and a polyamide-6 fabric is moved about therein for one minute, then drained by squeezing between two rollers, and immediately rinsed in acetone. A deep'and uniform blue shade is thus obtained having a fastness to rubbing, washing and light comparable to that obtained by dyeing in an aqueous bath. I
If, instead of the dyestuff mentioned above, one of those indicated in Table 1 below is used in the form of the 'free acid, the dyeing conditions remaining the C.|. Acid Red 57 (reaction product in acid medium red of diazo derivative of (N,N-diethylsulphamoyl)-2 aniline with amino-2 naphthol-S sulphonicfi acid C.I.;Aeid Y ellow 2 5 (C l9r lndexljo. 18835) yellow N4,N4'-bis (1-amino-2-sulpho-4-anthrLT blue quinonyl)-4,4-diamino-3 ,3 ,5 ,5 -tetra '5 methyl-diphenyl-methane EXAMPLE 2 10 parts of the dyestuff C.l. Acid Blue 129 in the form of the acid are dissolved at about 100C in 1,000 parts of diethylene glycol. This solution is raised to a temperature of C. and a polyamide-6 fabric is 0 moved about therein for one minute, then drained by squeezing between two rollers and rinsed immediately in acetone. A result comparableto that obtained in the first paragraph of Example 1 is obtained.
EXAMPLE 3 20 parts of the dyestuff C.l. Acid Blue 129 in the form of the acid are dissolved in about 100C. in 1,000
. parts of glycerine. This solution is raised to a temperature of 1 C. and a polyamide-6 fabric is dyed therein as in Example 1, a similar result being obtained.
EXAMPLE 4 On replacing the polyamide-6 fabric in Example 1 by a polyamide 6-6 fabric and operating at 130C. instead of 110C. a unifonn blue shade having good fastness to washing and rubbing is also obtained.
