Description

Patented Aug. 7,
comma or TEXTILE MATERIALS George Rivat, Lyon, France, assignor to Celanese Corporation of AmericaI a corporation of Delaware No Drawing.
9 Claims.
This invention relates the coloring of textile materials containing ce ulose acetateor other organic derivatives of cellulose ina very economilose yarn by a method that isvery economical.
cal and expeditious manner.
An object of my invention is to color textile materials comprising organic derivative of celluand which produces excellent results. A further object of my invention is to'color cellulose acetate material by a process employing dyestuffs that have little or no affinity for cellulose acetate material when applied in the ordinary manner.
' Still another object of my invention is to print fabrics by applying the dyestuil' in such a manner that the necessity of steaming is obviated. Other objects'of my invention will appear from the following detailed description.
I have found that ifdyestufls are applied to textile materials containing organic derivatives of cellulose in thej presence of a relatively large amount, of volatile organic liquid of a relatively high boiling point, whichliquid exerts at least a softening action on the organic derivative of 100 C. is sufficient to fix the dye, and thus the use of therelatively expensive ager or cotton steamer for fixing by steaming is not required,
Thirdly, brilliant colors may be obtained with the use of very small quantities of dyestuff. Furthermore if a delu'stered fabric is printed in accord.- ance with this invention the parts printed not only'become colored, but also assume a bright lustre.
In accordance with my invention I color fabrics containing organic derivatives of cellulose by applying thereto a composition containing a suitable dyestui! and a volatile organic liquid havinga boiling point above 100 (3. that has at least a softening action on the organic derivative of cellulose. r 4
The textile material to be treated may be in the form of a fabric containing yarns of organic derivatives of cellulose such as organic esters of cellulose or cellulose ethers. Examplesof or-"' ganic esters of cellulose are cellulose acetate,
cellulose 'formate; cellulose propionate and cellulose butyrate, while examples of cellulose ethers are ethyl cellulose, methyl cellulose and benzyl cellulose. The fabric may be a mixed fabric containing yarns of organic derivatives of cellulose and yarns of other fibres such as cotton, reconstituted cellulose, natural silk, wool, etc. Someof 00 the dyestufls that may be used have no affinity Application February at, 1931, Serial No. 511,313
for the said other fibres, and thus differential color effects may be obtained.
c The dyestufi may be applied locally in the form of a paste by printing or by spraying or brushing through stencils on to the fabric.
The compositioncontaining the dye, as stated, contains a volatile organic liquid which has a boiling point above 100 C. and is a solvent for or acts to soften the organic derivative of cellulose. Such organic liquid is preferably miscible with water. Examples of suitable liquids in the case of the treatment of cellulose acetate material are ethyl lactate, diacetone alcohol, and the acetate of mono ethyl ether of ethylene glycol. A suitable amount of organic liquid is used, in the case of ethyl lactate this amount being 200 to 400 cc. per
litre of composition.
Dyestuffs of various classes may be employed. This may be the indigosols, the basic dyestuffs and certain vat dyestuffs. A remarkable feature of this invention is that the acid dyes, which have little or no affinity for cellulose acetate material when applied in the ordinary manner, produce excellent colorations when employed in this invention.
After the application of the dyestufl composi tion, the fabric may be given a simple drying at a temperature below 100 0., say to 80 C., by passing over heated cans or through a heated atmosphere or in any other suitable manner. The ordinary expensive steaming operation need not be employed, although its use is not excluded from the scope of this invention.
If a fabric containing delustered cellulose acetate yarn is printed with a paste made in accordance with this invention, and the fabric then dried, the locally treated parts become lustrous, thus producing'lustrous colored efiects against a mattebackground. i
In order further to illustrate my invention, but without being limited thereto, the following speciflc examples are given. 1
Example I s fabric consisting of cellulose acetate yarn is printed with a paste made as follows:
Dyestufi i 10 to 40 grams, Glyezine (thlodiglycol) to 80 grams Water 160 grams "Ethyl lactate 200 to 600 cc.
Gumarabic thickener or colloresine (methyl cellulose) other thickener (1:1) v 400 grams As dyestuff. the following may be used:
Formyl violet 5 B (color index No. 698) Milling green (color index No. 667) Chromacetine blue 8 (color index No. 884)v Acridine red (color index No. 770) Rhoduline blue (color index No. 658) Chrornazurine Hi 3. (color index No. 879) CupranilBrown B (color index No. 560) Benzyl violet (color index No. 683) Induline (color index No. 861) Acridine orange (color index No. 788) Acridine red P. S. (color. index No. 740) Alkali blue (color index No. 704) Rhodamine 3 G. 0. (color index No. 749) Metanile yellow (color index No. 138) Milling red (color index No. 344) Polar red (color index No. 430) Rhoduline yellow 6 G (color index No. 815) Benzyl green (color index No. 667) If the fabric contains reconstituted cellulose or cotton, differential color effects may be obtained by using the following dyestufis which have no direct affinity for cotton or cellulose; polar red, alkali blue, benzyl violet, milling green, benzyl green or metanile yellow, etc.
After printing, the fabric is dried at '10 to C. for suflicient time to permit the vaporization of the ethyl lactate. A short washing with luke warm water then follows, after which the fabric is soaped at 50 C. for 3 to 5 minutes in a soap solution containing 2 to 3 grams of soap per litre. The fabric is finally rinsed in the ordinary manner.
Example 11 A fabric consisting of cellulose acetate yarn is printed with the following paste:
Grams Diphenyl black base, 40 to 50 Aniline; 100 to 120 Ethyl lactate 200 Glacial acetic acid 120 Water and thickener 530 After printing with the above paste, the fabric is rapidly dried at 60 to 70 C. and is passed into a bath consisting of a solution having the following composition:
7 Grams Sodium bichromate 15 Water 950 Sulfuric acid of 66 B 35 The fabric is allowed to remain in this bichromate bath at 15 to 20 C. for 2 minutes, is then rinsed in cold water, treated in a bath containing a cold solution of sodium carbonate of 5 grams per litre for 1 minute, then scoured in a soap bath at 80 C. for 5 minutes and finally washed.
The fabric is dyed a black color which is very bright and fast to rubbing.
It is to be understood that the foregoing .detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.
Having described my invention, what I claim and desire to secure by Letters Patent is:
