This invention relates to improvements in the coloration of textile materials and particularly to improvements in the coloration of mixed textile materials containing filaments or fibres of organic derivatives of cellulose and other filaments or fibres, for example cotton fibres.
According to the present invention mixed textile materials containing filaments, yarns or the like of organic derivatives of cellulose and other 10 filamentary constitutents are solid or cross-dyed by impregnating the materials with diazotisable bases, including diazotisable dyestuffs, which, when diazotised and coupled, form dyestufls both for the organic derivative of cellulose constituents and for the other constituents, and then effecting diazotisation and coupling of the diazotised bases. Preferably the coupling components for the organic derivative of. cellulose constituents are incorporated in the materials before diazotisation.
With suitable components, coupling to form the dyestuff for the organic derivative of cellulose materials may take place in the cold, e. g. simultaneously with diazotisation. In other cases it may be desirable to treat the materials at an increased temperature, e. g. 60 to 80 C., in the presence of the coupling component after formation of the dyestuff for the cotton or other constituent has been effected at a lower temperature, e. g. 10 to 20 C.
- While it is preferable to incorporate the coupling component for the organic derivative of cellulose constituent in the materials before diazotisation this is not essential and if desired I the whole of the coupling component or components may be introduced into thefabric or other material after diazotisation. In ithls case 'boric acid or other sihtable buffering agent may be introduced into the medium containing the coupling component, after cold coupling of the it! diazo compound on the cotton fibre has been effected, in order to assist the coupling of the diazo compound on the cellulose acetate or other organic derivative of cellulose filaments during a treatment at raised temperature.
The following are examples of the dyeing of mixed fabrics according to the process of the present invention:--
Example 1 60 A cellulose acetate-cotton woven fabric is introduced into a dyebath containing about 3% of a 10% paste containing 1-amino-3-methoxy benzene-4azo-dimethylaniline, 0.4% of a 10% paste containing 4-nitro 2-methoxy amino benzene, about 10% of Chlorazol Black B. H. (Color Index No. 401), about 1% of naphthol A. s., 0.3% of caustic soda and 1% of boric acid. The dyebath ratio is about :1. and the initial temperature is C., the temperature being raised during an hour to about 80 C. Two additions 5 of of Glaubers salt are made during the treatment. After this treatment the fabric is washed off and diazotised at 10-20 C. for 30 minutes in a 30:1 bath containing about 5% of sodium nitrite and 20% of formic acid. It is then washed off and introduced into a 30:1 bath containing about 1% of naphthol A. S. and 0.3% caustic soda and is worked first for about 30 minutes at a temperature of 10-15" C. to form the cotton dyestufi and then for a further 30 minutes 15 at a temperature of 75 C. to form the cellulose acetate dyestuif. The fabric is then introduced into a cold soap bath having a soap concentration of about 0.25% and containing about 3% of soda ash, the temperature being raised to 75 C. during about half an hour. The fabric is then washed off and dried.
The proportions of reagents given above are all based on the weight of the fabric except where otherwise stated.
Example 2 A mixed cellulose acetate viscose fabric is dyed in a bath containing 10% of ortho-methoxy benzene azoa-naphthylamine and 4% of diazo fast yellow 3GL, exhaustion being assisted, if necessary, by the addition of salt. The material is then diazotised in the cold, rinsed and treated in a bath containing 2% of p-naphthol at room temperature, the temperature being gradually raised to about C.
In this manner a dyed mixed fabric is obtained in which the cellulose acetate yarn is dyed a deep purple and the viscose yarn a reddish orange.
Example 3 A mixed cellulose acetate viscose fabric is dyed in a bath containing the following constituents:
Per cent Fast red RL base 1 Naphthol ASLT 2 Sodium hydroxide 0.5 Chlorazol Black BH. (Color Index No. 401)- 10 The alkali is buffered with boric acid or glucose and the material is treated for about an hour at to C. with the addition of 50% of. Glaubers salt to increase the exhaustion of the cotton color. After rinsing the material is introduced into a 15:1 bath containing 5% of sodium nitrite and 20% of formic acid and worked cold for 30 minutes. Diazotisation of the bases and coupling on the cellulose acetate take place in this bath, a deep red color being developed after about 30 minutes. The material is then rinsed and introduced into a fresh bath, containing one gran; per litre of soda ash and 1% of naphthol ASLT dissolved in 0.25% of caustic soda, to complete coupling on the viscose.
In this manner a dyed mixed fabric is obtained in which the cellulose acetate constituents are colored a deep red and the viscose constituents a navy blue, coupling on both the constituents being completed at a temperature of about 30 C.
Example 4 A cellulose acetateviscose fabric is dyed in a similar manner to that described in Example 3 using a bath containing the following constituents:
Per cent Fast red RL base 1 Naphthol ASLT 2 Caustic soda 0.5 Diazo fast green GFL 3 After treatment with the above liquor the fabric is introduced into a diazotising bath for about 30 minutes in which diazotisation is effected and coupling on the cellulose acetate constituents takes place. The fabric is then rinsed and introduced into a bath containing 1% of phenylmethyl-pyrozolone in which coupling on the viscose' takes place.
In this manner a dyed mixed fabric is obtained in which the cellulose acetate constituents are colored a bright red and the viscose constituents green.
In each of the above examples the fabric treated contains about 50% of each type of yarn. In Examples 2-4 the proportions of dyestuffs are calculated on the weights of the respective yarns and the other reagents on the weights of the fabrics, except where otherwise stated.
The process of the present invention is applicable to the coloring of mixed yarns, fabrics and other textile materials containing constituents made of cellulose acetate or other organic derivative of cellulose together with other constituents, for example cotton or regenerated cellulose fibres. The organic derivative of cellulose constituents may for example be continuous filaments, obtained for example by the extrusion of a solution of cellulose acetate, spun yarns, made from staple fibres obtained for example from such continuous filaments or by the acetylation of cotton or other cellulosig fibres without destroying their structure, or filamentary materials of relatively high denier such as straw or slit foil. The process is applicable to the production of any suitable azo dyestuffs on the mixed mate rials. As examples of suitable bases which may be employed may be mentioned o-chloraniline, para-nitraniline, para-nitrobenzene azo-paraxylidine, m-nitro-p-toluidine, o-anisidine, dianisidine, a-naphthylamine, benzidine, and mono aceto-acetyl 4.4 diamino azobenzene, while as examples of suitable coupling components may be mentioned resorcin, fi-naphthol, anaphthol, amino-phenols and amino-naphthols, oxy-naphthoic acids, ,B-naphthylamine, p.amino diphcnylamine, and fi-keto-acidyl arylides, e. g. diaceto acetyl-o-tolidide.
