The Dyeing of Woollen Fabrics Part 12

Lignorosine used as the a.s.sistant mordant in the above recipes works very well, and gives bright shades.

_Fast Bordeaux_.--Prepare a bath with 4 lb. Chromogene I, 1-1/2 lb.

Alizarine Red 1 W S, 1 lb. Alizarine Red 5 W S, 1/2 lb. Fast Acid Violet R, 10 lb. Glauber's salt and 3 lb. sulphuric acid. Work at the boil for one hour, then lift; add to the same bath 3 lb. b.i.+.c.hromate of potash and 1-1/2 lb. sulphuric acid. Re-enter the goods and work to shade, then lift, wash and dry.

_Terra Cotta_.--Make a dye-bath of 30 lb. Fustic, 8 lb. Turmeric, 30 lb. Sanders and 10 lb. Sumac. Boil the goods in this for one (p. 121) hour, then add 3 lb. sulphate of copper, previously dissolved in water, boil for one hour; cool, sadden with Copperas, using about 3-1/2 lb. or less if required; then rinse and dry.

Another method is to mordant the goods at a boil for one and a half hours in 2 lb. b.i.+.c.hromate of potash and 2 lb. tartar. Drain and wash.

Dye in a fresh bath with 8 lb. sanders and 10 lb. fustic; afterwards sadden with 1/4 lb. copperas; allow to stand one hour; wash and dry.

There are several brands of Orange dyes which can be used; they differ but little in shade from one another. In general they give fast colours. The Tropaeolines also dye orange shades, but they are not so fast as the other dyes which have been named.

_Gold Orange_.--Make a dye-bath with 1/2 lb. Diamine scarlet B, 2 lb.

Anthracene Yellow C, 50 lb. Glauber's salt, 5 lb. acetate of ammonia.

Enter the wool, work for half an hour, then add 3 lb. bisulphate of soda. Boil again for half an hour, then lift. Add 3 lb. fluoride of chrome, re-enter the wool, boil again for half an hour, then lift, wash and dry. This gives a very fast orange.

_Gold Orange_. Mordant with 3 lb. b.i.+.c.hromate of potash, and 2 lb.

tartar, for one and a half hours at the boil; rinse. Then dye in a new bath with 1 lb. Alizarine Orange, 17 lb. Fustic extract. Work at 100 F. for half an hour, then heat gradually to the boil and dye for one and a half hours at that temperature; lift, rinse and wash.

#Olive Yellow on Worsted Yarn.#--Mordant the yarn by boiling for one hour or one and a half hours in a bath of 3 lb. b.i.+.c.hromate of potash; then dye in a bath of 1-1/2 lb. Gambine Yellow and 10 lb. of fustic chips.

Red and orange form a kind of group of colours which shade off one into the other almost imperceptibly by using a range of dyes such as Croceine A Z, Brilliant Croceine 9 B, Brilliant Croceine 7 B, Brilliant Croceine 5 B, Brilliant Croceine 3 B, Brilliant Croceine M O O, Crystal Scarlet 6 R, Brilliant Cochineal 4 R, Brilliant Croceine B, Brilliant Cochineal 2 R, Orange E N Z, and Croceine Orange E N. It is possible to dye shades from a scarlet crimson to a bright orange.
