Part 8

II. Have the feathers well cleaned, respectively, bleached, and rinsed. Prepare a hot bath (170-190° F.), with a little sulphuric acid, just enough to give it a slightly sour taste, add a few drops of solution of fast brown and a little more solution of acid green (both dyestuffs of the Farbwerke, formerly Meister, Lucius & Bruening, Hoechst-on-Main); take of them one or two drops, respectively two or three drops per gallon of water for a light shade and increase quantities proportionally for darker shades. Rinse after dying, starch and dry.

III. Take white feathers or grays very well bleached to nearly white, scour and rinse them well. Prepare a bath of warm water, 100-120° F. and some vinegar so as to give it a distinct sour taste; add to a basin full, or about one-half gallon of the bath a little solution of fast brown, one or two drops of indigo carmine, and a trace of turmeric. Lay the feathers down in the bath for fifteen or twenty minutes and agitate them repeatedly in the liquid to make them level.

For a Gray Beige, add a little nigrosine to the bath and proceed as above.

MODES.

For the modes it is impossible to give generally applicable directions, as these colors are of an indefinitely varying character, consisting in modifications of other compound or mixed colors which are affected by sometimes very trifling, unmeasureable additions of a toning dyestuff, and coloring effects are produced which cannot be described nor defined by names, but must be judged by the experienced eye of the dyer. Most of these colors are derived from grays or browns as above remarked, and the safest way for the dyer is, to begin dyeing with light shades of the prevalent characteristic color and give them the peculiar tone by the addition of other colors by drops. The proportions of dyestuffs thus ascertained for light shades, are then easy to increase for deeper shades. It needs not to be remarked, that for these colors the feathers must be bleached, especially for light and medium shades, and that, if unbleached, grays are to be dyed in dark shades, the effect of the natural color must be considered in composing the dye.

In general all modes are dyed upon a bath which is acidulated with bisulphate of soda, with azo orange, azo yellow, azo brown, acid violet, indigo carmine, solid blue or cloth blue, induline or nigrosine, archil or acid fuchsine. For brown modes, solution of Bismarck brown may be added at the beginning, in which case the other dyestuffs serve only for giving the peculiar tone.

For a yellowish green mode take orange O, azo yellow, and solid blue (fast blue); for darker shades add a little violet 6 B., or a few drops sulphate of indigo. If alizarine dyestuffs are to be employed, use tartaric acid as mordant, but for neutral dyestuffs add also a little alum to the dyebath.

For gray modes use the same dyestuffs as above, excepting the orange, instead of which a blue-red dyestuff is to be employed, such as azo rubine, bordeaux, fuchsine, etc., with the addition of a little acid green. The bath must be acidulated with a little sulphuric acid, or better with tartaric acid, or tartaric acid and alum, and after dyeing the feathers must be rinsed, starched and dried as usual.

For particularly fast modes add only tartaric acid to the dyebath and no alum, and a few drops of solution of thio-scarlet, thio-rubine, and thio-brown; for grays add a little azo yellow and sadden with solid blue. Alum does not agree with the thio dyestuffs which are manufactured by Dahl & Co., Barmin, and are fast against soap and light. Feathers dyed with these dyestuffs which have become soiled, can be washed, therefore, with neutral soap without injury to the color, but must naturally be dressed anew.

RESEDA.

Scour the white, respectively bleached feathers and rinse well. Prepare a bath with five per cent., of the weight of feathers, bisulphate of soda, to which add gradually and carefully the filtered solution of acid violet, fast yellow and fuchsine S., making the additions from the beginning in small quantities only, until the desired tone and shade are obtained; then enter and work the feathers to sample at 173° F.

It is for this dye particularly important that the bisulphate of soda used be crystallized, that is, pure bisulphate free from surplus sulphuric acid, while the commercial article is often nothing but a mixture of Glauber salt (sulphate of soda) into sulphuric acid, answer for this dye.

A good reseda is also easily obtained by adding to the acidulated bath small quantities of decoction of logwood and turmeric, so as to give a feeble bath. Enter the scoured and bleached feathers, after rinsing, at 170° F., work them for about fifteen minutes, until level, and sadden with a little solution of blue stone. Rinse, starch and dry as usual.

ORDINARY GREEN.

For two and one-half pounds of feathers boil two and one-half pounds of fustic for one-half hour with three quarts of water, pour the decoction off and boil the chips again for one-half hour with three quarts of water, mix the two decoctions and strain. Add three ounces alum and one and one-half ounces tartar, enter the feathers well scoured and rinsed, and dye to shade at 170° F. Or, prepare the dyestuffs of decoction of fustic or turmeric, and indigo carmine, according to shade, enter at 170° F., work for one-half hour while slowly raising the temperature to near the boiling point, and dye to sample; lift, rinse, squeeze and starch as usual.

LIGHT GREEN.

I. Scour, respectively bleach, and rinse the feathers. Prepare a hot bath with the solution of forty per cent., of the weight of feathers, tannin, and treat the feathers in it for 1 hour at 170°F. Prepare a bath with a filtered solution of methyl green, according to shade, tone, if a yellowish green is wanted, with the clear solution of picric acid, and dye to sample at 150° F. Lift, squeeze and starch without rinsing.

II. A better color is obtained upon a lightly acidulated bath (with sulphuric acid) with acid green, malachite green, fast green, etc., that is, with the filtered solutions of these dyestuff's, added to the bath in quantities of from ten to twenty per cent. to suit the shade. Enter at 170° F.; dye for twenty or thirty minutes, lift, rinse, squeeze and dry with starch. If a yellowish tone is wanted, add the clear solution of picric acid, or of acid yellow.

MOSS GREEN.

Scour and rinse the feathers well; for dark shades unbleached grays may be used. Prepare a feebly acidulated bath with sulphuric acid, at a temperature near the boiling point; add turmeric freely and Guinea green G less. Enter the feathers and manipulate at the same temperature for fifteen or twenty minutes, according to the desired tone, re-enter and dye to shade.

By varying the proportions of the three dyestuffs, a great variety of green-brownish modes can be produced, which approach medium and dark bronzes the more the fast brown predominates in the composition of the color.

BOG GREEN.

This color is preferably dyed upon unbleached gray feathers. Scour and rinse them, prepare a decoction of green walnut husks or of sumac; lay the feathers down in it for two hours, working them from time to time; then add some decoction of logwood and dye to shade at 170° F., or indigo carmine and dye to shade while slowly raising the temperature to near the boiling point. Rinse, squeeze, starch and dry.

GRASS GREEN.

Scour, respectively bleach, and rinse the feathers. Prepare a boiling bath with turmeric and indigo carmine; chill, enter the feathers at 170° F., dye for one-half hour, raise the temperature slowly to near the boiling point and dye to shade, take up, rinse and pass through a handwarm bath of tartar; lift, squeeze, starch and dry.

RUSSIA GREEN.

I. Scour the feathers as usual and rinse well. Prepare a bath slightly acidulated with sulphuric acid, add two per cent., of the weight of feathers, acid green and one per cent. aniline navy blue dissolved in warm water and filtered acid, according to sample, some filtered decoction of turmeric or solution of fast yellow. Dye at 170° F. to shade, lift rinse and dry with starch.

II. Have the feathers well cleaned and rinsed. Prepare a bath twenty per cent., of the weight of feathers, new green, eight per cent. canarine, sixteen per cent. aniline blue black, sixty per cent. alum, and one-quarter litre sulphuric acid (for two and a half pounds of feathers). Bring the bath to a brisk boil, then chill with cold water, enter the feathers and work them for one hour; finally sadden and tone by adding some decoction of fustic and of logwood. Lift, rinse, squeeze, starch and dry.

III. Prepare a sharp hot bath with a little sulphuric acid; add Guinea green, according to shade, and tone by the addition of indigo carmine and turmeric; for very deep shades add also some nigrosine or fast blue-black, dissolved and filtered. Enter as hot as the feathers can be handled, work for one half hour; then raise the temperature slowly to near the boiling point and dye to shade.

The bath for deeper shades being not exhausted can be preserved for further use, refreshed by suitable additions of dyestuffs as required, but caution must be used as regards the subsequent additions of sulphuric acid, that not so much be added as to injure the feathers.

For Russia green, especially the darker shades of it, naturally gray and even black feathers can be used unbleached.

ROSE.

I. For this delicate color, as well as for the lightest shades of blue and pure yellow, absolutely white feathers must be used; scour them carefully and rinse them perfectly clean from soap or soda, and have the dyestuffs well dissolved and the solutions filtered. Prepare a handwarm bath with a little tartaric acid or acetic acid, to which some solution of eosine, rhodamine, azoeosine, safranine, coccine or ponceau 6 R. B. or ponceau R. R. Be particularly cautious in adding the dyestuff solutions gradually in small quantities, even by drops, to avoid over-dyeing, as by partly stripping of a too dark shade, a fine color can never be obtained, and the nature of the material demands that all unnecessary handling be avoided. After dyeing, rinse lightly, pass through starch and dry. The dyes with the ponceaus are faster than those with eosine or safranine.

II. Prepare a bath at hand heat with carthamine (extract of safflower), well dissolved and filtered, which add very gradually in small quantities, taking up the feathers each time before making a fresh addition, until the desired shade is nearly obtained, then add a little tartaric acid to the bath, re-enter the feathers and dye to shade; or dye first to shade upon the safflower bath, and then pass through a fresh, handwarm feeble bath of tartaric acid, which in this case can be used again for other colors, either as a fixing bath or in the composition of the dye bath.

RED.

Scour and rinse the feathers well; grays must be bleached as near to white as possible, and these ought only to be dyed dark shades of red. Prepare a bath with twenty per cent., of the weight of feathers, bisulphate of soda, and see, as in all cases, that it is well crystallized and dry. (Never use the article when it looks decayed, forms lumps or is moist). Add four to six per cent. azo red, according to the shade wanted, raise the temperature to 170° F., enter the feathers and work to shade; take out, starch and dry.

FAST ALIZARINE RED.

I. Scour and rinse the white, respectively bleached gray, feathers and prepare a bath of boiling water with eight per cent., of the weight of feathers, alum, four per cent. tartaric acid, two or three per cent. oxalic acid, and three per cent. alizarine red; let the bath boil for fifteen minutes, then let the temperature go down just below the boiling point. Lay down the feathers in the bath, which keep at near the boiling point for at least one hour before allowing it to go down to hand-heat; then continue for two or three hours longer, agitating the feathers from time to time; lift, rinse, starch and dry.

By using alizarine acid 2 A. bl. bl., a pure red, similar to Turkey red is obtained. Alizarine 1 W. S. gives scarlets. If the feathers are passed, before rinsing, through a strong soap bath, pretty blue tones are produced.

II. For a fuller red, striking towards bordeau, prepare a well concentrated boiling bath in the same manner with three per cent. bichromate of potash, one and one-half to two per cent. tartaric acid, one per cent. oxalic acid, and eight per cent. alizarine red 2 A. bl. bl. When all is dissolved, let the temperature go down below the boiling point, enter the feathers, and proceed as above.

SCARLET.

I. For this color naturally white feathers are preferably used, but well bleached grays may also be employed; scour and rinse well. Then fill your pan with boiling water, add a few handfuls of bran, let it well boil up, remove the bran from the bath and rub the feathers in the bath as in washing; then pass them three times through clean, cold water. While the feathers are draining, prepare another fresh bath of lukewarm water, to which add a little chloride of tin and, for one pound of feathers, about two pinches of starch and ninety grammes cochineal; then bring the bath to boil and let it gently boil for eight or ten minutes, shut off the steam or remove the pan from the fire, let it stand for a few minutes. Then lay the feathers down in the bath, taking care that they are well kept down in the liquid, work for twenty minutes diligently, then let them lodge in the bath for six to eight hours. As the combination of cochineal and the chloride is readily oxydized and changed to violet by the oxygen of the air, it is advisable to dye in a tinned pan with cover to shut out the air.

Then pass through three lukewarm waters, the last of which contains a little chloride of tin and about a pinch of cream of tartar.

II. Prepare a hot bath with twenty per cent. (of the weight of feathers) bisulphate of soda, well crystallized and dry, and four to six per cent. azo red, according to shade. Enter the feathers at 170° F., dye to sample in fifteen or twenty minutes, lift, starch and dry.

According to the brand of azo red which is used, either scarlet or ponceau is obtained. By mixing the various brands of azo red, a very fine ponceau is produced. If a very blue tone is desired, add to the bath some solution of coccinine (azo red blue touch).

PONCEAU.

I. Scour and rinse the white, respectively bleached feathers well. Prepare a nearly boiling bath, acidulated with sulphuric acid, to which simply add ponceau R. R. extra. Enter the feathers, operate at boiling heat one-half hour, then lay down the feathers and let them lodge until level; lift, rinse, starch and dry.

II. Prepare a sharp handwarm bath with one per cent. tartaric acid (of the weight of feathers), or with one per cent. Glauber salt and one-fourth per cent. sulphuric acid, to which add the filtered solutions of ponceau R. B., ponceau 6 R. B., and eosine S. extra B. Enter the feathers and agitate for twenty to thirty minutes, or until the desired shade is obtained; lift, rinse, starch and dry.

III. Lay down the feathers for four hours in a cold bath in which some chloride of tin has been dissolved; then dye for one-half hour in a hand warm bath of cochineal, lift and dry.

IV. Prepare a bath with one and one-half per cent., of the weight of feathers, saccharic acid, one-quarter per cent. tin salt, and six to seven per cent. cochineal, bring the bath to boil for one minute; then chill. Enter the scoured and rinsed feathers at hand heat, dye for three-quarters of an hour, take up and expose them for two hours to the air, rinse, starch and dry.

BORDEAUX.

Scour and rinse the feathers well. Prepare a boiling hot bath slightly acidulated with sulphuric acid, to which add a liberal quantity of ponceau 6 R. B., a few drops solution of aniline blue, and some yellow dyestuff, such as turmeric, fast yellow, or quinoline yellow, and bring the bath to boil for a few minutes. Then chill to sharp hand-heat, enter the feathers and work until level, and sample; if still too light, add some more of all these dyestuffs. As the bath shows from the beginning the color it will produce, it can be corrected before entering the feathers.

GARNET (RED).

I. Scour and rinse the feathers well clean, grays ought to be bleached. Prepare the dyebath as for ponceau (I.), or use an old ponceau bath, and add to it some aniline cerise (cherry red) and very little extract of indigo, or solution of fast blue-black. Enter feathers as hot as possible to handle, work for fifteen to twenty minutes while raising the temperature to boiling heat; then stop heating, lay down the feathers, and let them lodge until level; lift, rinse and dry.

II. Prepare a boiling hot, not boiling, bath of anotto, according to shade, enter the feathers, work them well through, then lay them down in the bath for twelve hours. Take them up, rinse, pass through a moderately strong alum bath, rinse again, and dye at 170°F., with either decoction of red wood (brazil, camwood, etc.,) or fuchsine; lift and dry.

GARNET (BROWN).

For very deep shades naturally gray feathers may be used unbleached with proper consideration of the tone of the bottom color. Have the feathers well cleaned and rinsed, and add to a bath of two gallons of water, one and one-quarter pounds cudbear and five ounces turmeric. Bring the bath to boil, boil for five or ten minutes, let cool down to 100° F., enter the feathers and dye to shade. Lift, starch and dry.

Or, utilize a used ruby bath (following) and add to it five ounces turmeric.

RUBY.

For a good color the feathers must be white, naturally or bleached; scour and rinse them well. Add to two gallons of water one and one-half pounds good cudbear, stir well, enter the feathers and work them, while slowly heating, as long as the hands can stand it. Then lay them down until colored to shade, lift, rinse well, starch and dry.

SALMON.

I. Salmon or "flesh" may be dyed upon bleached naturally gray feathers, in which case the creamy tint of the feathers must be taken into consideration and can be utilized for certain broken tones of the color. Have the feathers well washed in soap or soda, and rinsed perfectly clean. For dyeing prepare a bath as for rose, preferably with ponceau B. R., or utilize an old bath for rose, according to its strength and the shade to be produced, and add in either case a suitable, small quantity of filtered decoction of turmeric. Proceed as stated for dyeing rose, with the difference only, that the acid may be added to the dyebath at once, if the bath is made fresh. Particularly fine shades are obtained with rhodamine and turmeric, in a bath slightly acidulated with acetic acid, upon bleached grays.

II. Prepare a bath as for rose, with some solution of eosine, a little quinoline yellow, according to tone, and a little acetic acid, just enough to give the bath a slightly sour taste. Enter the well cleaned, or bleached feathers after rinsing, at hand heat and agitate them until the bath is well exhausted, or a level color, according to sample, obtained, rinse lightly, starch and dry.

AMARANTH.

After scouring and rinsing, prepare a bath with one and one-half ounces alum per gallon of water, at 75-80° F., and lay the feathers down in it over night. On the next morning rinse them in cold water; then dye them at hand-heat to nearly boiling heat in a strained decoction of Brazil wood (or camwood, hypernic, etc.) until the required shade is obtained, and rinse in warm water to which some tartar has been added; starch and dry.

BRONZE.

For this color naturally gray feathers may be used if a deep shade is to be dyed; for light shades they ought to be bleached. Scour and rinse the feathers well; then prepare a bath with five per cent., of the weight of feathers, bisulphate of soda, to which add azo orange, acid violet and extract of archil. Dissolve the dyestuffs, each separately in water, filter, add the clear solutions gradually in small quantities until the shade is nearly reached, then, in order to correct, by drops, until the exact depth and tone are obtained. Enter the feathers and dye to shade at 170° F. Instead of acid violet indigo carmine may be used; in this case, however, as the dyestuff runs up slowly and difficultly, work at 170° F., for twenty to thirty minutes, then raise the temperature slowly to near the boiling point and continue at that temperature, without actual boiling, until the required color is obtained. Then rinse, squeeze, starch and dry.

Bronze is also produced like drab, that is, with azo orange, acid violet and fuchsine S., but with greater quantities of dyestuff. Bronze is also obtained with the recipe for any dark brown, by making the yellow in it predominant; particularly good bronzes are in this manner obtained from dark chestnut brown.

OLIVE.

I. Clean the feathers by laying them down for six hours, or over night, in a weak warm solution of soda crystals (1° B.) to which add so much ammonia as to give it a faint odor; take up when completely ungreased and rinse well in lukewarm and cold waters. Prepare the dyebath with five per cent., of the weight of feathers, bisulphate of soda, to which add filtered solutions of indigo carmine, archil and fast yellow as required for the sample. As the indigo carmine is slow to dye up and requires boiling heat or a temperature near it, dye first the feathers blue with indigo carmine, then let the bath cool down to 170° F., and add the solutions of archil and fast yellow in small successive quantities, so as to be able to give the accurate tone.

Instead of extract of archil, fast red or bordeaux may be employed.

To avoid any possible injury to the feathers by the high temperature necessary for indigo carmine to run up, in its stead a solution of alkaline blue or of acid Victoria blue. Take up and dry the feathers without rinsing.

II. Scour well and rinse the feathers, and prepare a bath with three per cent. alum (of the weight of feathers), to which add azo orange and some indigo carmine; enter at 170° F., dye for fifteen or twenty minutes, then raise the temperature slowly to near the boiling point and dye to shade. Lift and dry.

By beginning with small quantities of the dyestuffs and successively increasing them and varying their proportions, a series of fine shades from light old gold to the deepest olive, near black can be produced.

III. Prepare a boiling bath, in which dissolve one per cent., of the weight of feathers, alum, one per cent. Glauber salt, and add a little sulphuric acid; let cool down to 170° F., add some fast yellow, a little solution of archil and of sulphate of indigo, work for fifteen minutes while raising the temperature to the boiling point, and sadden with blue black, lift, rinse and dry with starch.

IV. Prepare a sharp handwarm bath with a little sulphuric acid, to which add the clear solution of a little quinoline yellow or turmeric, and acid green; enter the feathers and work for fifteen minutes, or until they have taken a sufficiently nourished yellow-green color; then take them up, add to the bath some solution of fast brown, as required by the sample and dye at 170° F. to shade; rinse, squeeze, starch and dry. The brown dyestuff must be added very carefully in small doses, best by drops, in order to obtain with certainty any of the great varieties of shades, from olive green to olive brown, as required.

VIOLET.
