Dyes and dyeing -- Cotton
_Green and Claret._--First bath, 3-1/2 lb. Naphthol red C and 10 lb.
bisulphate of soda. Second bath, 2 lb. Diamine sky blue F F, 1-1/4 lb.
Thioflavine S, and 15 lb. Glauber's salt.
_Gold Brown and Blue._--First bath, 2-1/2 oz. orange E N Z, 1-1/2 oz.
Orange G G, 1/4 oz. Cyanole extra and 10 lb. bisulphate of soda. Second
bath, 14 oz. Diamine sky blue F F and 15 lb. Glauber's salt.
_Dark Brown and Blue._--First bath, 1/2 lb. Orange G G, 1-1/2 oz. Orange
E N Z, 1-1/2 oz. Cyanole extra and 10 lb. bisulphate of soda. Second
bath, 12 oz. Diamine sky blue F F and 15 lb. Glauber's salt.
_Black and Green Blue._--First bath, 3 lb. Orange G G, 1 lb. Brilliant
cochineal 4 R, 1 lb. Fast acid green B N and 10 lb. Glauber's salt.
Second bath, 1-3/4 lb. Diamine sky blue F F, 3-1/4 lb. Thioflavine S and
15 lb. Glauber's salt.
We may here note that in all the above recipes the second bath (for
dying the cotton) should be used cold or at lukewarm heat and as strong
as possible. It is not completely exhausted of colour, only about
one-half going on the fibre. If kept as a standing bath this feature
should be borne in mind, and less dye-stuff used in the dyeing of the
second and following lots of goods.
_Blue and Gold Yellow._--3 lb. Diamine orange G, 13 oz. Naphthol blue G,
14-1/2 oz. Formyl violet S 4 B and 15 lb. Glauber's salt. Work at just
under the boil.
_Brown and Blue._--1 lb. Diamine steel blue L, 9-1/2 oz. Diamine sky
blue, 1 lb. Orange E N Z, 1 lb. Indian yellow G, 1-3/4 oz. Naphthol blue
black and 15 lb. Glauber s salt. Work at 170 deg. to 180 deg. F.
In these two last recipes only one bath is used, all the dyes being
added at once. This is possible if care be taken that dye-stuffs of two
kinds are used, one or more which will dye wool and not cotton from
neutral baths, and those direct dyes which dye cotton better than wool.
The temperature should also be kept below the boil and carefully
regulated as the operation proceeds and the results begin to show
themselves.
_Grey and Orange._--First bath, 3 oz. Orange extra, 1-1/4 lb. Cyanole
extra, 1 lb. Azo red A and 10 lb. bisulphate of soda. Second bath, 5 oz.
Diamine orange D C and 3 oz. Diamine fast yellow B.
_Green and Red._--First bath, 2 lb. Croceine A Z, and 10 lb. Glauber's
salt. Second bath, 1 lb. Diamine sky blue F F, 1/2 lb. Thioflavine S,
and 15 lb. Glauber's salt.
_Brown and Violet._--First bath, 3/4 lb. Orange extra, 3/4 lb. Cyanole
extra, and 10 lb. bisulphate of soda. Second bath, 5 oz. Diamine
brilliant blue G, and 15 lb. Glauber's salt.

yellow S, and 10 lb. bisulphate of soda. Second bath 3 lb. Diamine fast
