The dye preparation thus produced is mixed with approximately equal parts 'of water to form the dye bath which, it will be seen, contains a predominant amount of water. The dye bath itself need not be brought to the boiling point and in fact the dyeing operations are efiectively carried on in a relatively cold bath.
My invention pertains particularly to the use of a dye which is normally insoluble and immiscible in water or a dye such as is used for dyeing artificial silks, such as cellulose acetate, and which is normally insoluble, but miscible with water. Such dyes are made soluble in water by the addition to the dye bath of cellosolve (ethylene glycol monoethyl ether). For dyeing many materials I may merely add acetone to the bath and do not require Cellosolve (ethylene glycol monoethyl ether), but in such cases I have found that the amount of acetone used must be equal to substantially 10% of the amount of water. Such a bath would be suitable for dyeing materials such as silk, wool, felt (such as that used in felt hats), and the like. To the bath I may add any suitable mordants, such as acetic acid in dyeing silk, or sulfuric acid or Glaubers salt when dyeing wool. The piece goods or'other article dyed is merely immersed in a relatively cold bath and then immediately withdrawn and allowed to dry. Such cold immersion and dyeing greatly reduces or practically eliminates the shrinkage hazard which invariably follows in the case of dyeing operations involving the boiling of material dyed.
In dyeing cellulose acetates, such as artificial taffetas and celanese with a dye which is nor-'- mally insoluble in water, I regard it of importance to include in the bath of dye water an amount of acetone equal to about 10% of the amount of water, and an amount of Cellosolve (ethylene glycol monoethyl ether) which would be substantially greater than the amount of acetone,
' asuitable mordant or fixing agent such as Glaubers salt being included in the bath as above. For materials other than cellulose acetates the amount of Cellosolve (ethylene glycol monoethyl ether) in the bath will range from 10% to 90% of. the amount of acetone. The proportion of cellosolve (ethylene glycol monoethyl ether) used will thus depend somewhat on the character of the dye material, the color desired and the weight of material.
While ordinarily in dyeing according to my improved method and with my improved dye baths, boiling is not required, it is to be understood that it is also within my invention to carry out the dyeing operation in which a boiling bath quires from one to two hours; I can secure satistactory results by immersion in the bath for an interval of approximately ten or fifteen minutes. Practically all materials can be dyed by my method within half an hour. Shrinkage of the material is thus effectively prevented.
Experience with the method and the dye bath disclosed herein has demonstrated that the use of approximately 10% of acetone in the water bath results in effecting great economy. Tests have shown that where such proportion of. acetone is used over dyeing is avoided and an enormous amount of material can be dyed without depleting the bath of the dye; whereas, other conditions remaining the same, but without such percentage of acetone, the bath is quickly rendered unfit for further use without addition of dye stuff. Moreover, by the incorporation of acetone and Cellosolve (ethylene glycol monoethyl ether) in the bath streaky and spotty dyeing is avoided and fast colors of uniform shade are consistently secured.
While I have described with great particularity certain specific embodiments of the invention, it is to be understood that the details given are to be interpreted as an illustrative rather than in a limiting sense, since various modifications in detail may be made by those skilled in the art without departing from the invention as defined in the appended claims.
What I claim is:
1. An aqueous dye bath comprising a normally water insoluble dye, a monoalkyl ether of ethylene glycol, and acetone.
2. An aqueous dye bath comprising a normally water insoluble dye, ethylene glycol monoethyl ether, acetone and water.
3. The process of dyeing comprising treating the material or article to be dyed in an aqueous dye bath containing a dye normally insoluble in water, a monoalkyl ether of. ethylene glycol in 'amount sufficient to make the dye soluble in water, and a predominant amount of water.
4. The process of dyeing comprising treating the material or article to be dyed in an aqueous dye bath containing a dye normally insoluble in water, ethylene glycol monoethyl ether in amount sufficient to make the dye soluble in water, and a predominant amount of water.
5. The process of dyeing comprising treating the material or article to be dyed in an aqueous dye bath containing'a dye adapted for use on organic derivatives of cellulose and normally insoluble in water, a monoalkyl ether of ethylene glycol in amount sufiicient to make the dye soluble in water, and a predominant amount of water.
6. The process of dyeing comprising treating the material or article to be dyed in an aqueous dye bath containing a dye adapted for use on organic derivatives of cellulose and normally insoluble in water, ethylene glycol monoethylether in amount sufficient to make the dye soluble in water, and a predominant amount of water.
