As practically all these dye-woods are now not used by themselves it has not been deemed necessary to give specific recipes for their application, on previous pages several are given showing their use in combination with other dyes.
The dye-stuff Dinitroso-resorcine or Solid green O is used along with iron mordants for producing fast greens and with chrome mordants for producing browns to a limited extent in cotton dyeing. The following recipes give the details of the process.
Green.—Steep the cotton yarn or cloth in the following liquor until well impregnated, then dry: 3 gallons iron liquor (pyrolignite of iron), 22° Tw. gallons of water, ¾ gallon acetic acid, 12° Tw., 2 lb. ammonium chloride. Then pass the cotton through a warm bath of 3 oz. phosphate of soda and 4 oz. chalk per gallon, then enter into a dye-bath containing 6 lb. Solid green O. Work as described for dyeing
alizarine red. For darker greens of a Russian green shade use 10 lb. of solid green O, in the dye-bath.
Brown.—A fine brown is got by steeping the cotton in a bath of 8 lb. Solid green O, 6¾ gallons water, 1½ gallons ammonia and 2 lb. acetate of chrome; dry, then pass through a soap-bath, wash and dry.
Deep Olive Brown.—Mix 8 lb. Solid green O and 4½ lb. borax with 6 gallons water, add ½ lb. Turkey-red oil, 5 lb. ammonia, then 2 gallons water and 1½ lb. copper-soda solution and another 2 gallons water. Steep the cotton in this, dry, soap well and wash. The copper-soda solution is made from 10 lb. chloride of copper (75° Tw.), 5 lb. tartaric acid, 12 lb. caustic soda (75° Tw.) and 4 lb. glycerine.
Khaki.—Make the dye liquor from 14 lb. Solid green O, ½ lb. Alizarine yellow N, 1 lb. caustic soda (36° Tw.), ½ lb. Turkey-red oil and 8 gallons water. To this add 2½ lb. acetate of chrome (32° Tw.), 2¼ lb. copper-soda solution and 4 gallons water.
Sage Green.—Use 1¼ lb. Solid green O, 3 lb. caustic soda (36° Tw.), ½ lb. Ceruleine, ½ lb. Turkey-red oil, 1 gallon water to which is added 2½ lb. acetate of chrome (32° Tw.) and 2¼ lb. copper-soda solution dissolved in 4 gallons water.
Pale Brown.—Use 4 lb. Solid green O, 2½ lb. borax, 3 lb. ammonia, ½ lb. Turkey-red oil, 6 gallons of water and 1½ lb. copper-soda solution dissolved in 2 gallons water.
Pale Fawn Brown.—The dye-bath is made from ½ lb. Alizarine, 1¼ lb. Solid green O, 1½ lb. borax, ½ lb. Turkey-red oil and 5 gallons of water to which is added 1½ lb. acetate of chrome (32° Tw.), 1½ lb. copper-soda solution and 4 gallons water. In all cases the cotton is steeped in the dye liquors until thoroughly impregnated, then the excess liquor is wrung out, the cotton dried, then passed through a soap bath, washed well and dried.
