The Dyeing of Woollen Fabrics Part 9

_Fast Scarlet_.--Prepare a dye-bath with 3 lb. Glauber's salt, 1-1/4 lb. sulphuric acid, 2-1/2 lb. Brilliant Scarlet 4 R. Work at the boil for one and a half hours.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet 2 R J, 10 lb.

Glauber's salt and 2 lb. sulphuric acid. The goods may be entered at about 150 F., and the temperature raised at the boil and maintained at that heat for one hour, then the goods are lifted, rinsed and dried.

The method given in the above recipes is that usually followed (p. 106) with the acid colours. When closely woven or thick goods are being dyed, where it is desired that the colour should penetrate well into the substance of the goods, the following modification of working may be adopted:--

The dye-bath is made up with the dye-stuff and Glauber's salt only, and the goods are worked in this at the boil until they are thoroughly impregnated with the dye-stuff liquor, then the acid is added in small quant.i.ties at a time, and the dyeing is continued for one hour to fix the colouring matter on the wool fibre. The goods may then be lifted out, washed and dried.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet F R, 10 lb. Glauber's salt and 2 lb. sulphuric acid. In place of scarlet F R, the F 2 R or F 3 R brands may be used, the latter giving the reddest shades.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet O O, 10 lb. Glauber's salt and 2 lb. sulphuric acid. Scarlet O dyes a yellower shade of scarlet, while scarlets O O and O O O dye slightly redder shades.

_Scarlet_.--The dye-bath is made with 3 lb. Brilliant Ponceau 2 R, 10 lb. Glauber's salt and 10 lb. bisulphate of soda. This gives a brilliant shade of scarlet. Brilliant Ponceau G, used in the same way, gives a much yellower tone of scarlet, the R gives a slightly yellower tone, while the 3 and 4 R brands dye redder shades.

_Bluish Red_.--The dye-bath is made with 2 lb. Brilliant Croceine B, 10 lb. Glauber's salt, and 10 lb. bisulphate of soda. Brilliant croceine B B and the brand M dye redder shades of scarlet.

_Red_.--Make the dye-bath with 3 lb. Milling Red R, 20 lb. Glauber's salt, and 5 lb. acetic acid. This is a good bright shade, and is quite fast to soaping and milling.

_Deep Scarlet_.--Dye with 3 lb. Chromotrop R, 10 lb. Glauber's (p. 107) salt, and 2 lb. sulphuric acid. This scarlet is very fast to milling, acid and light.

_Red_.--Make the dye-bath with 2 lb. Victoria Scarlet R, 1 lb.

Victoria Rubine O, 10 lb. Glauber's salt, and 4 lb. sulphuric acid. A fine deep scarlet red is obtained.

_Scarlet_.--Dye with 2 lb. Brilliant Orseille C, 10 lb. Glauber's salt, and 3 lb. sulphuric acid. This gives a bright bluish shade of scarlet.

_Red_.--Dye with 1 lb. Emin Red and 5 lb. bisulphate of soda.

_Scarlet_.--Make the dye-bath with 3 lb. Croceine Scarlet 3 R, 10 lb.

Glauber's salt, and 2 lb. sulphuric acid.

_Fawn Red_.--Make the dye-bath with 1-1/2 oz. Cyanole, 1-1/2 oz.

Orange extra, 2-1/2 oz. Archil Subst.i.tute N, 10 lb. Glauber's salt, and 2 lb. sulphuric acid. This gives a nice light tint of fawn red, of a somewhat bluish tone.

_Deep Fawn Red_.--A very deep shade of fawn red is dyed with 4-1/2 oz.

Cyanole, 2-1/4 lb. Orange extra, 1-1/4 lb. Archil Subst.i.tute N, 10 lb.

Glauber's salt, and 2 lb. sulphuric acid. The same dye-stuffs are used as in the last, but the result is a deeper shade, of a yellow tone.

_Crushed Strawberry Red_.--Use 4 oz. Chromotrop 2 R, 2 oz. Cyanine B, 1 oz. Azo yellow, 10 lb. Glauber's salt, and 2 lb. sulphuric acid.

_Pale Lilac Rose_.--Dye with 1 oz. Chromotrop 2 R, 1/2 oz. Cyanine B, 1/2 oz. Azo yellow, 10 lb. Glauber's salt, and 2 lb. sulphuric acid.

_Deep Fawn_.--Dye with 3-1/4 oz. Chromotrop 2 R, 1-1/2 oz. Orange G, 2 oz. Cyanine B, 4 oz. Fast Acid Blue R, 10 lb. acetic acid, and 20 lb. Glauber's salt.

_Crimson_.--Make the dye-bath with 3 lb. t.i.tan Red 6 B, 20 lb. salt, with a little acetic acid, and work at the boil. This gives a fine shade of crimson, fast to acids and capable of standing milling very well.

_Deep Crimson_.--A bright and deep crimson is dyed with 4 lb. Fast (p. 108) Acid Magenta B, 10 lb. Glauber's salt, and 3 lb. sulphuric acid, working at the boil.

_Pale Crimson_.--Make the dye-bath with 2 lb. Fast Acid Magenta B, 10 lb. Glauber's salt, and 2 lb. sulphuric acid, working at the boil.

Level shades are readily obtained, and the dye is fast to was.h.i.+ng.

_Deep Crimson_.--Make the dye-bath with 4 lb. Azo Fuchsine G, 10 lb.

Glauber's salt, and 2 lb. sulphuric acid. This gives a very deep shade of crimson, of a bluish tone.

_Bluish Crimson_.--Use in the dye-bath 2 lb. Azo Fuchsine G, 10 lb.

Glauber's salt, and 2 lb. sulphuric acid.

_Pale Bluish Crimson_.--Use in the dye-bath 1 lb. Azo Fuchsine G, 10 lb. Glauber's salt, and 2 lb. sulphuric acid. This gives a very bright shade of pale crimson. The B brand of the Azo Fuchsines gives slightly bluer shades than the above.

_Deep Crimson_.--A very solid crimson is dyed in a bath containing 3 lb. Azo Red A, 2 oz. Orange extra, 2 oz. Cyanole extra, 10 lb.

Glauber's salt, and 2 lb. sulphuric acid. Work at the boil.

_Bright Crimson_.--A fine bluish crimson can be dyed on wool with 4 lb. Azo Red A, 10 lb. Glauber's salt, and 10 lb. bisulphate of soda.

Work at the boil.

_Deep Crimson_.--A good shade can be dyed with 6 lb. Amaranth, 10 lb.

Glauber's salt, and 10 lb. bisulphate of soda, working at the boil.

_Brilliant Pale Bluish Crimson_.--A really brilliant shade, bordering on a violet red, is dyed in a bath containing 1-1/2 lb. Fast Acid Violet R, 10 lb. Glauber's salt, and 2 lb. sulphuric acid.

_Bluish Crimson_.--Make the dye-bath with 3 lb. Croceine Scarlet, 10 lb. Glauber's salt, and 2 lb. sulphuric acid. This gives a good full shade of a bluish tone and very bright.

_Bluish Crimson_.--Dye with 3 lb. Chromotrop 6 B, 10 lb.

Glauber's salt, and 3 lb. sulphuric acid. This gives a fine tint, (p. 109) very fast to acids, milling and light.

_Purple_.--Make the dye-bath with 3 lb. Chromotrop 10 B, 10 lb.

Glauber's salt, and 3 lb. sulphuric acid.

The Chromotrops are remarkable for the fulness of the shades they dye, the brightness of their tint, and their fastness to acids, was.h.i.+ng and light.

_Purple_.--Use 4 lb. Azo Fuchsine B, 10 lb. Glauber's salt, and 2 lb.

sulphuric acid.

_Bluish Purple_.--A very dark shade of purple is dyed with 4 lb. Azo Acid Violet 4 R, 10 lb. Glauber's salt, and 2 lb. sulphuric acid.

#Bordeaux Reds#.--These are shades that lie intermediately between the scarlets and the crimsons. They are in general duller than the scarlets, and have a more solid and fuller look; while they are less blue in tone than the crimson. They can be obtained from a large variety of dye-stuffs, and the recipes given below may be regarded as typical examples.

_Bright Bordeaux Red_.--Make the dye-bath with 1 lb. Azo Bordeaux, 10 lb. Glauber's salt, and 2 lb. sulphuric acid, working at the boil to shade. This is a very bright shade, of a somewhat bluish tone.
