. Patented July 21, 1953 DYEING F CELLULOSE DERIVATIVE TEXTILE MATERIALS George C.,'Ward and William T. Haggerty, Jr. lCumberland, Md., assignors to' Celanese Cor- 'poration' of America, New York, N. Y., a corporat'ion-of Delaware No Drawing.
v 3 Claims.
This invention relates to the dyeing of textile materials and relates more particularlyto'the dyeing of synthetic textile materials with vat dyes.
Notwithstanding the excellent dyeings obtained on cellulosic materials with the aid of vat dyes, the said dyes have not found extensive usefor the dyeing of synthetic textile materials such as, for example, textile materials having a basis of. or-
. ganic acid esters of cellulose including cellulose acetate, cellulose prop ionate, cellulose butyrate, cellulose acetate propionat-e, cellulose acetate butyrate and the like, polyamides, polyesters, polyurethanes, vinyl chloride polymers and copolymers, and acrylic materials. The conventional dyebaths employed for vat dyeing cellulosic material either fail to produce a satisfactory dyeing resistant to light and washing on such synthetic textile materials, or they cause a saponification or degradation of .said synthetic textile materials. Although many specially compounded dyebaths have been proposed for dyeing synthetic textile materials with vat dyes, many previously proposed dyebaths,
vat dyes cannot be employed successfully in said provide a novel dyebath and, process for dyeing synthetic textile materials with vat dyes which will be free from the foregoing and other difiiculties.
A further object of this invention is to provide a novel dyebath and process for dyeing synthetic textile materials with a wide range of vat dyes in shades that are resistant to light and washing and without saponifying or degrading the synthetic textile materials.
Other objects of this invention will be apparent from the following detailed description and claims.
According to the present invention, we have discovered that synthetic textile materials may be dyed successfully with a wide range of vat dyes from an aqueous dyebath containing the leuco vat of said dyes together with an alkali metal carbonate such as sodium or potassium carbonate, an alkylolamine such as mono-, di,
or tri-ethanolamine, and a water-miscible organic liquid capable of swelling the synthetic textile materials such as butyl Carbitol, butyl Cellosolve, diacetone alcohol, triethyl phosphate and the like. The dyebath containing the alkali metal carbonate, alkylolamine and swelling agent effects a' satisfactory dyeing of the synthetic textile materials without saponifying or otherwisedegrading the same. In preparing the It is an important object. of this invention to Application December 27, 1950, Seria'lNo. 203,036
dyebath there is employed, for each 100 parts by weight of water, from about 0.1 to 1 part by weight of the alkali metal carbonate, from about 0.5 to 10 parts by weight of the alkylolamine and from about 3 to parts by weight of the water-miscible organic liquid capable of swelling the synthetic textile .material. The leuco vat of the dye may advantageously be prepared in the dyebath itself by incorporating therein the vat dye together with "a reducing agent such as sodium hydrosulfite, all ma manner well known in the art. The concentration of the dyestuif in the dyebath maybe varied over a wide range depending upon the depth of shade desired in the dyed textile material. Suitable vat dyes that may be employed in compounding the dyebath of the present invention are, for example Ca1coso1 Fast Yellow, Ponsol Jade Green (C. I. 1101), Indanthrene Blue BCSN (C. I. 1114) Carba-nthrene Red BN (C. I. 1162) Indanthrene BlueBCL, In-
danthrene Olive TA, Indanthrene Olive Green BA, Indanthrene Violet FFBNA (C. I. 1163), In-
danthrene Brown GWF (C. I; 1152) and Amanthrene Grey BR.
In effecting the dyeing, the synthetictextile material is immersedin the dyebath which 'is maintained at a temperature of between about 40 and 60 C. for a period of'between about 10 and minutes, following-which the temperature of the dyebath' is raised to between about 70 and 90 C. and the synthetic textile materialis held therein for an additional period of between about 30 and 90 minutes. ."I'hef synthetic textile ma- .terialjis then rinsed and the leuco vat of the dye is oxidized by treating said material with a bath containing a suitable oxidizing agent such as, for example, sodium dichromate, sodium perborate, or hydrogen peroxide. The dyebath and process of the present invention may be employed for dyeing the synthetictextile materials in the form I of fabrics or packages of yarn, but is especially suited for the dyeing of the synthetic textile materials in the form of staple fibers since it enables an even penetration and a uniform dyeing of the staple fibers to be obtained readily.
The following examples are given to illustrate this invention further.
Example I In 300 parts by weight of water at 50 C. there is dissolved 0.2 part by weight of Pensol Jade Green (20% color), 0.5 part by weight of sodium carbonate, 2.5 parts by weight of diethanolamine, 4' parts by weight of sodium hydrosulfite, 1 part by weight of tetrasodium pyrophosphate 8.; and 20 parts by weight of butyl Carbitol. There is immersed into this dyebath for 15 minutes, 10 parts by weight of cellulose acetate staple fiber, following which the temperature of the dyebath is raised to 80 C. and maintained at that temperature for 45 minutes. The staple fiber is then removed from the dyebath, rinsed well with warm water and oxidized with a bath maintained at 60 C. and containing parts by weight of acetic acid and 2 parts by weight of sodium dichromate dissolved in 500 parts by weight of water. After the oxidation is complete, the staple fiber is soaped at 70 C., washed and dried; The staple fiber is uniformly dyed a deep jade color.
The same dyebath uniformly dyes nylon staple a jade green, polyurethane staple a deep blue green, a polyester staple from terephthalic acid and ethylene glycol a blue green, an acrylic staple from acrylonitrile a jade green, and a vinyl chloride-vinyl acetate copolymer staple a jade green. This dyebath does not dye cotton.
Example II red, a polyester staple from terephthalic acid and ethylene glycol a dull red, an acrylic staple from acrylonitrile a light red, and a vinyl chloridevinyl acetate copolymer staple a dark red. This dyebath does not dye cotton.
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 our invention.
