Definitions
- This invention relates to an improved dye composition for use in the metachromedyeing process and to a method of dyeing therewith.
- metallizable dyes In the past there have been four general procedures employed in dyeing With metallizable dyes.
- the majority of metallizable dyes are azo dyes containing metallizable groups ortho to the azo group. There are, however, a few dyes which are not azo dyes such as certain anthraquinone colors which are also metallizable and they are included in the scope of the present invention.
- the first utilizes preformed metallized dyes and requires the formation of the metallized dyes before it is introduced into the dye bath. Practically all of the metallizable dyes maybe utilized in this process but it is subject toa number of disadvantages.
- the dye is 'not very efiiciently used, the dye bath is poorly exhausted, and the color value is not as high as desirable in some cases.
- the second process is referred to as an after chrome procedure in which the fabric is dyed with metallizable dyes and then subjected to an after treatment with a solution of a compound of the metal to be introduced into the dye molecule.
- the dye is applied the same asan acid color and ,it .requires an extra process andzextra timefor the formation of the metallizedcomplex.
- the third procedure is the so-called bottom chrome process in which a metal compound is first deposited in the textile fiber and then the dye is applied and the metallizedcompiex forms in-the'fiber.
- this process is an extremely long one requiring several steps. 7
- the fourth procedure is the so-called meta chrome process in which the metallizable dye and when dyeing basic fibers such as the natural animal fibers, wool, silk, and the like or synthetic fibers of similar type from casein, polyamides and 'so forth. Certain dyes give good penetration and others donot." The dyes which do not give good penetration, particularly in the case of heavier shades have, therefore been considered unsuitable-for use in the metachrome process and have required resort to the process starting, out with the preformed metallized dye, orthe top or bottom chrome processes with their attendant disadvantages.
- the cationic surface active agent is colloidized with a mixture such as dextrin or the like no difliculty in scum formation is encountered; It is not necessary that the dyestuff be mixed with the surface active agent before colloidization as the same beneficialeffect is obtained in either case.
- the present invention is not limited to compositions in which the dye is already blended or both dye and mordant are blended as excellent results may be obtained by making up metachrome baths with the colloidized cationic surface active agent and the dyestuif separately.
- . -It is an advantage that the present invention is 'very flexible where it is desired to produce a marked advantage that it is not necessary for the dyer to stock a large'number of blends of color and surface active agent.
- hydrophilic colloids uch as a carbohydrate gum, that is, dextrine, polyvinyl alcohol.
- a hydrophilic colloids uch as a carbohydrate gum, that is, dextrine, polyvinyl alcohol.
- yellow corn 'dextrine The working is in a stiff paste, for example, in a Werner-Pfleiderer dough mixer.
- colloidized cationic surface active agent in the specification and claims is limited to such products which are colloidized with hydrophilic colloids
- the word colloidized in the claims will be used in no other sense and particularly is not intended to cover mere fine dispersion of particles of the cationic surface active agent.
- colloidization may be effected in the presence of deflocculating surface active agents although it is not necessary in all cases. It is, also, of importance that colloidized material which is desired in the dry form should be dried at a sufiiciently' low temperature, preferably in a vacuum dryer, so that-the colloidized nature of thematerialis not destroyed and it retains a high degree -of I good autodis-persibility and high total 'dispersibility.
- the products of the present invention show good keeping qualities particularly when marketed in the dry form. Furthermore, the metachrome dyeing field is opened to a number of colors which formerly could not be used in this process or could not be used to produce deep shades. At the same time the advantages of the present inventionare obtained without any costly added ingredients and without expensive processing.

Description
Patented Jan. 6, 1948 UNITED STATES PATENT OFFICE METACHROME DYEING WITH A COLLOID- rznn CATIONIC AGENT George L. Royer, North Plainfield, and Chester A.
Amick, Bound Brook, N. 3., assignors to American Cyanamid Company, New York, N. Y., a corporation of Maine 16 Claims. (01. 8-30) j t This invention relates to an improved dye composition for use in the metachromedyeing process and to a method of dyeing therewith.
In the past there have been four general procedures employed in dyeing With metallizable dyes. The majority of metallizable dyes are azo dyes containing metallizable groups ortho to the azo group. There are, however, a few dyes which are not azo dyes such as certain anthraquinone colors which are also metallizable and they are included in the scope of the present invention. The first utilizes preformed metallized dyes and requires the formation of the metallized dyes before it is introduced into the dye bath. Practically all of the metallizable dyes maybe utilized in this process but it is subject toa number of disadvantages. The dye is 'not very efiiciently used, the dye bath is poorly exhausted, and the color value is not as high as desirable in some cases. The second process is referred to as an after chrome procedure in which the fabric is dyed with metallizable dyes and then subjected to an after treatment with a solution of a compound of the metal to be introduced into the dye molecule. As the name implies the dye is applied the same asan acid color and ,it .requires an extra process andzextra timefor the formation of the metallizedcomplex.
The third procedure is the so-called bottom chrome process in which a metal compound is first deposited in the textile fiber and then the dye is applied and the metallizedcompiex forms in-the'fiber. Hereagain this process is an extremely long one requiring several steps. 7
The fourth procedure is the so-called meta chrome process in which the metallizable dye and when dyeing basic fibers such as the natural animal fibers, wool, silk, and the like or synthetic fibers of similar type from casein, polyamides and 'so forth. Certain dyes give good penetration and others donot." The dyes which do not give good penetration, particularly in the case of heavier shades have, therefore been considered unsuitable-for use in the metachrome process and have required resort to the process starting, out with the preformed metallized dye, orthe top or bottom chrome processes with their attendant disadvantages.
It has been proposed to add cationic surface active agents to metachrome baths. increased penetration into the individual fibers results but the cationic surface active reagent reacts with the acid groups of the metallizable dyes and the metal compound to form a water insoluble complex which tends to come down on the fabric or fiber to be dyed in the form of a scum resulting in streaky and non-uniform dyeing. For this reason, the use of the cationic surface active agents in a metachrome process for the dyeing of basic nitrogeneous fibers has been considered unsuitable.
The disadvantages of scum formation led to the development of an improved process described and claimed in the copending application of Millson and Royer, Serial No. 420,504, filed November 26, 1941, now abandoned, in Which a non-ionic surface active agent was added to the bath to disperse the scum formation constituents. Even the improved process of the Millson and Royer application requires making up a special dye bath on the part of the dyer and rather careful control in addition to the added cost of the non-ionic surface active agent.
According to the present invention We have found that if the cationic surface active agent is colloidized with a mixture such as dextrin or the like no difliculty in scum formation is encountered; It is not necessary that the dyestuff be mixed with the surface active agent before colloidization as the same beneficialeffect is obtained in either case.
The present invention is not limited to compositions in which the dye is already blended or both dye and mordant are blended as excellent results may be obtained by making up metachrome baths with the colloidized cationic surface active agent and the dyestuif separately.
. -It is an advantage that the present invention is 'very flexible where it is desired to produce a marked advantage that it is not necessary for the dyer to stock a large'number of blends of color and surface active agent. On the otherhand,
Somewhat HESS.
3 where large runs of the same strength dyeing are required in many cases it is more convenient and more desirable for the dyer to buy a blend of the surface active agent and color with or without the 'mordant' also blended so that all he has to do is to add Water andmake'up a bath.
This obviates any necessity of careful control of proportions and reduces the requirement for surface active agent may be effected by working it with a hydrophilic colloidsuch as a carbohydrate gum, that is, dextrine, polyvinyl alcohol. calcium lignin sulfonate, sodium lignin sulfonate, White tapioca dextrine, polyacrylamides, salts of polyacrylic acid, etc. Because of its cheapness andexcellent working properties We prefer to use yellow corn 'dextrine. The working is in a stiff paste, for example, in a Werner-Pfleiderer dough mixer. The use of the term "colloidized cationic surface active agent in the specification and claims is limited to such products which are colloidized with hydrophilic colloids The colloidization as described above, and as will be more fully set out in the examples, results in the coating of the individual particles of the cationic surface active agentwith a film of hydrophilic colloid which on careful drying and grinding produces a product of good autodispersibility and high total dispersibility. The word colloidized in the claims will be used in no other sense and particularly is not intended to cover mere fine dispersion of particles of the cationic surface active agent.
If desired the colloidization may be effected in the presence of deflocculating surface active agents although it is not necessary in all cases. It is, also, of importance that colloidized material which is desired in the dry form should be dried at a sufiiciently' low temperature, preferably in a vacuum dryer, so that-the colloidized nature of thematerialis not destroyed and it retains a high degree -of I good autodis-persibility and high total 'dispersibility.
It is not intended to limit-the present invention to any particular theory and it has not as yet been determined definitely just why the colloidized cationic surface active agent will give high penetration in a metachrome bath without scum formation whereas when the cationic surface active agent is uncolloidized scum difficulties are encountered unless a non-ionic surface-active agent is added.
The products of the present invention show good keeping qualities particularly when marketed in the dry form. Furthermore, the metachrome dyeing field is opened to a number of colors which formerly could not be used in this process or could not be used to produce deep shades. At the same time the advantages of the present inventionare obtained without any costly added ingredients and without expensive processing.
Improved results are obtained with a large number of metallizable dyes. Sometimes the improvement is in strength andpenetration and sometimes there is noted an improvement in level- With' certain dyes improvements in both qualities :are obtained.
The invention will be described in greater detail in conjunction with specific examples which show typical compositions and dyeing procedures according to the present invention. Unless otherwise stated' alliparts are'by'weight;
Example 1 1,000 parts of corn dextrin made by dextrinizing corn 'starch'rwith' hydrochloric acid are pasted 'with 200'- partsof the condensation product of octadecyl guanidine bicarbonate and ethylene oxide (1 mole'tofi' moles). These are then placed ina dough mixer'and wet out with just enough watertogi-v'efia thick plastic magma. This is worked for one hour in the mixer or until it gives a smooth homogeneous paste. The paste is then transferred to an enameled tray, placed in a vacuum-dryer and dried at a temperature of about 70"CZ' with a vacuum of 28-29". When it has thoroughly dried, the product is ground and screened-thrbugh-a BIO-mesh screen. This product is called the colloidized cationic agent. parts of this colloidized cationic agent and'40 parts of-thefinely-powdered red dye- (C: I. 652) are drybl'ended'until uniformly mixed. The re-' sulting productis then dyed as follows:
Blended color'-5-% on weight of skein.
(NH4)2S04-10%' on weight of skein. K2C1"2O71% on :Weight of skein. Bathratio'80.-l.
The'skein'i'is'first' wet out by soaking in cold distilled -water'and'then entered into the respec-; tive dye bath art-approximately 120 F. The dye liquor is then raised to the boil gradually, in 1; hour, after which it is boiled for /2 hour with frequent turning ofthe skein to insure uniform dye ing. After 30 minutes boiling, /s% of 66 B; H2304 onthe-weight of the skein is addedand the boiling continued for a second 30 minutesr At the end of this boiling period, of 66 B. I-IzSOi' is'add'e'cl and-the boiling continued for another half hour; I The skein is then rinsedand air dried. w The finished-dyeing is red and has good fastness properties: iii;
If an equivalent dyeing is made from the same dyestuff represented byC. I. 652 in which-no colloidized cationic. agentis present, and using the same dyeing procedure, the resultant dyeing is weak and commercially unsatisfactory;
Example 2 A'dyeing of'the blended color of Example 1 is made in the following dye liquor:
5% Blended color.
2% or less ammonium hydroxideto give a pH not greater than nine.
10% Epsom salts.
-1 Bath ratio (400 cc. water).
All percentages are based on the weight of'the wool to be dyed.
A 5 gram wool "skein is prewet with water. then entered into the dye bath atapproximately F. From this pointon; the dyeing rates and additions of acid are similar to the dyeing procedure of Example-1 except 2% and 4%'additions1of'28% acetic'acid are used instead of the /s%'and H2304.
The dyed skein is'a rich deep' red, very level dyed and generally superior to a dyeing of equivalent strength applied by :the usual top" chrome dyeing procedure.
Example 3 The preparationof the blended, color and the dyeing procedure of Example 1 is repeated, except the color used is 1-amino-2-hydroxy-4-sulfo naphthalene diazotized and coupled to alpha naphthol (C. I. 201). The shade of the skein so dyed with the blended material containing the colloidized cationic agent is blue-black whereas the skein dyed with the color which has not been blended with colloidized cationic agent is a gray.
Example 4 The product of Example 3 is dye tested by the dyeing method used in Example 2. Here the improvement in color value is especially marked over that obtained from a. dyestufi that has not been blended with colloidized cationic agent.
Example 5 The procedure of Example 1 is repeated except the color used in this example is 1-amino-2 hydroxyl-sulfo-fi nitro naphthalene diazo coupled to alpha naphthol (C. I. 203). When dye tested by the procedure of Example 1, the product which has been blended with the colloidized cationic agent is definitely stronger and brighter than the dyeing obtained from the color which has not been blended with colloidized cationic agent.
Example 6 The procedure of Example 1 is repeated except the color in this example is 1-hydroxy-2-amino- 4-nitro benzene diazo coupled to fi-sulfo-beta naphthol. When dye tested by the dyeing procedure of Example 1, the product which has been blended with the colloidized cationic agent gives a red-brown shade.
Example 7 The dyestuff of Example 6 is dye tested by the dyeing procedure of Example 2. The color is a beautiful rich brown having a fiber levelness very similar to that obtained by the top chrome dyeing procedure.
Example 8 Example 9 The procedures of Example 1 are repeated, except the color in this example is a, dye having color index 274. The dyeings made with the colloidized cationic agent are strong, bright and more fiber level than the dyeings made from material which has no colloidized cationic agent present. This is especially true when the dyeing procedure of Example 2 is used.
Example 10 The composition of Example 8 is dye tested by the dyeing procedure of Example 1 except no and additions are made. of acid, the color value of the dyeings is superior to those obtained under similar conditions when no colloidized cationic agent is present. The dye bath in which the colloidized product was used is Even without the addition time e better exhausted than the dye bath in which no colloidized cationic agent is present.
, Example 11 A 5 gram wool skein is dyed with 5% of the color of Example 8, which has been blended with colloidized cationic agent, and 4% of a mordant containing 82.5% Epsom salts and17.5% K2CI2O'I. Both percentages are based on the weight of the wool. After the skein is entered at 120 F, the dyeing is carried out as in Example 1. The color value of the dye skein is a good blue-black having good fiber and fabric levelness.
Example 12 The procedure of the preceding example is repeated except sufiicient ammonium hydroxide or equivalent ammonium salt is added to give an initial pH of 8.0-9.0 before the skein is entered.
Then the dyeing is carried out as in the preceding example. The color value of the dyed skein is a rich strong blue-black having fiber and fabric levelness practically equal to that obtained from a top chrome dyeing.

9. Example 24 parts of the condensation product of octadecyl guanidine bicarbonate and ethylene oxide, are colloidized using 25 parts of polyvinyl alcohol and sufiicient water to give a stiff paste. The product is mixed and ground as in Example 15 and subsequently dried in vacuum at a temperature of 60-70 C. It is dye tested as follows:
100 milligrams of the dye, C. I. 202, are dissolved in 100 cc. of boiling water and transferred to a dyeing beaker. 150 milligrams of the colloidized cationic agent likewise is dissolved in hot water and added to the dye beaker. If desired, the color and the colloidized cationic agent can be admixed and dissolved at the same time. 500 milligrams of ammonium sulfate and 50 milligrams of potassium bichromate are then added to the dye beaker which is made up to a total volume of 400 cc.
A 5 gram woolen skein is prewet with water and entered into the dye bath at approximately 120 F., after which the dyeing is carried out as in Example 15.
The wool dyed with the dyestuff, C. I. 202, by this procedure has a strong blue-black shade, good fiber and fabric levelness and is commercially satisfactory.
Example 25 The procedure of the preceding experiment is repeated, except a high viscosity polyvinyl alcohol is used. This product can be substituted for the colloidized material of the preceding example and essentially the same results obtained after the wool has been dyed. If no colloidized cationic agent is present, the resultant dyeing is a gray.
Example 26 The procedure of the preceding example is repeated, except the polyvinyl alcohol is replaced by calcium lignin sulfonate. When this product has been dried and ground, it can be satisfactorily substituted for the colloidized material of Example 25. Sodium lignin sulfonate when substituted for calcium lignin sulfonate in this example ives equivalent results.
Example 27 The procedure of the preceding example is followed, except 250 parts of a solution of water soluble methyl cellulose having a viscosity of 190 centipoises is used as the colloidizing agent instead of the calcium lignin sulfonate. When vacuum dried, this product formed a film. 3% (150 milligrams) of this film-like material was added to the dye bath and the dyeing carried out as in the preceding example, except no sodium lignin sulfonate was present. The resultant dyeing was not quite as strong as in the preceding example, but it was definitely a blue-black instead of the gray obtained when no colloidized cationic agent is present.
Example 28 The product of Example 1 is dyed on nylon by the method of Example 12. An excellent bright red shade is obtained which has good levelness.
Example 29 V The product of Example 8 when dyed on nylon by the method of the preceding example, gave a bright, blue shade having good levelness.
Example 30 The composition of the preceding example is used, except the color is nitro amino phenol diazotized and coupled with meta phenylene diamine which is diazotized and coupled to5-sulfonaphthol and the composition is dyed on a synthetic casein fiber. A level, brown dyeing having good fastness properties is obtained.
Example 31 The procedure of Example 2 is repeated except the color (C. I. 1085) is used instead of the red 7 tages with a large range of metallizable dyes.
The advantages will vary with difierent dyes and in general some yellow dyes show less marked advantages than dyes of other shades.
