Definitions
- the present invention relates to a process of dyeing with substantive colors and to composition of matter useful in such dyeing processes.
- a urea or a derivative thereof such as urea itself, methyl urea, methylol urea, dimethylol urea or a salt of one of these compounds, for instance, a chloride, a nitrate, a sulfate or a like salt, or a substance capable of forming one of these substances, such as ammonium cyanate, cyanamide or a similar compound.
- Such compounds have a protective action even in an alkaline dye bath and scarcely influence the pH-value of the dye bath during the dyeing operation
- the said additions have a levelling and compensating eflect on the mixture of vegetable and animal fibers and thus facilitate the production of even tints on the mixed fibers. Even if the material is boiled for a long time, the wool is not too strongly dyed. The process, therefore, represents a considerable technical progress.
- the prescribed additions may be mixed with substances hitherto used in dye ng xed thereto; the parts are by weight:
- a textile fabric consisting of 70 parts of wool and parts of spun rayon (viscose artificial textile fiber) is dyed with 1 per cent. of the azo-dyestuff' 3-amino-6-hydroxy-l-benzoic acidalphanaphthyl-amine' gamma-acid with the addition of 30 per cent. of crystallized sodium sulfate and'5-10% of urea.
- the dyeing which in the absence of the urea tends to be discolored shows the normal tint even if the material is boiled for several hours.
- a textile fabric consisting of '10 parts of wool and 30 parts of spun rayon (viscose artificial textile fiber) is dyed with 1 per cent of the azo-dyestuff 3-amino-6-hydroxy-1-benzoic acid-+alphanaphthyl-aminegamma-acid while adding 30% of crystallized sodium sulfate and 0.5-2% of dimethylol urea.
- the dyeing which in the absence of the dimethylol urea. tends to be discolored shows the normal tint even if the material is boiled for several hours.
- a textile fabric is dyed in the manner indicated in Example 1, except that instead of urea, there is used 5% of ammonium cyanate, which, under the conditions of the dyeing process, is transformed into urea.
- a textile fabric is dyed in the manner indicated in Example 1, 3% of urea chloride being used instead of urea.
- ammonium sulfate may be used, with the same success.
- Example '7 The material named in Example '7 is dyed in the manner described therein, 1% of urea ni- 5 trate being used instead of 5% of methyl urea.
- ureanto the dyebath and 30 parts or viscose artificial textile fiber are 10 and t dyeing i t usualmannen dyed with 2% of the dyestui'i' No. 540 of Schultz's Farbstofltabellen, 1931, 5% of methyl urea (obtained by reaction of methyllamine sulfate with potassium cyanate) and 20 per cent. 01 crys- 2.
- the process which comprises dyeing textile fibers with a. v substantive dyestufl in a boiling dyebath, in the presence of urea.
