Dye in as concentrated a bath as possible at about 160 deg. F. with about 6 lb. Diamine black B H, 1 lb. Diamine sky blue, pat., per 100 lb. of dry goods, 1/2 lb. Diamine orange D C, pat., with an addition of 6-1/2 oz. soap, 4 to 5 dr. soda per 10 gallons liquor, 16 oz. Glauber's salt. After dyeing rinse well in a bath containing 6 dr. soda and 3 oz. soap per 10 gallons water, diazotised in a fresh bath with 4 lb. nitrite of soda and 12 lb. hydrochloric acid (per 100 lb. of dry goods), rinse thoroughly and develop with 3 to 16 oz. phenylene diamine (93 per cent.), with addition of 1 to 2 lb. soda. These two operations should follow each other as quickly as possible, also care has to be taken that the diazotised goods are not exposed to direct sunlight or heat, which causes unlevel dyeings. The silk is then cleaned as far as possible by hot soaping, and dyed at about 120 deg. to 140 deg. F., with acid dye-stuffs and the addition of sulphuric acid. After dyeing rinse as usual and brighten. _Yellow and Violet,_--Dye the cotton with 2 lb. Diamine fast yellow A, the silk with 1 lb. Cyanole extra, and 1 lb. Forinyl violet S 4 B. _Black and Blue._--Dye the cotton with 5 lb. Diamine black B H, 1 lb. Diamine sky blue, and 1/4 lb. Diamine orange D C. After dyeing, diazotise and develop with phenylene diamine as described above. Then dye the silk with 1/2 lb. Pure soluble blue and 1 lb. Cyanole extra. _Black and Crimson._--Dye the black as in the previous recipe, then dye the silk with 2 lb. Brilliant croceine 3 B and 1/2 lb. Rhodamine S. _Blue and Gold._--Dye the cotton with 2 lb. Diamine sky blue and the silk with 1 lb. Fast yellow S. _Dark Blue and Green._--Dye the cotton with 1-1/2 lb. Diamine black B H, 1-1/2 lb. Diamine sky blue and 1/2 lb. Diamine azo blue 2 R; the silk with 2 lb. Naphthol yellow S and 1 lb. New methylene blue G G. _Violet and Yellow._--Dye the cotton with 2 oz. Diamine violet N and the silk with 1 lb. Fast yellow S. _Orange and Violet._--Dye the cotton with 2 lb. Diamine orange D C and the silk with 1 lb. Formyl violet S 4 B. _Dark Blue and Olive._--Dye the cotton with 1-1/2 lb. Diamineral blue R and 1/2 lb. Diamine azo blue 2 R, and the silk with 1 lb. Naphthol yellow B and 1 lb. Orange G G. _Green and Pink._--Dye the cotton with 1-1/2 lb. Diamine fast yellow A and 1/4 lb. Diamine sky blue, and the silk with 1 lb. Erythrosine B. _Brown and Blue._--Dye the cotton with 3 lb. Mikado brown 2 B, and the silk with 1/2 lb. Pure blue. It is quite possible to produce two coloured effects containing blue in one bath by using Alkali blue as a constituent with a direct dye which works only on to the cotton, the alkali blue going on to the silk, as, for example, in the following recipes:-- _Orange and Blue._--The dye-bath is made with 3 lb. Mikado orange 5 R O and 1-1/4 lb. Alkali blue 6 B. After the dyeing the goods are rinsed, then passed through a bath of 1-1/2 lb. sulphuric acid in 10 gallons water, washed well and dried.
