18 Good Recipes For Dyeing Of Silk
(1) INDIGO VAT FOR BLUE
Silk is dyed in a similar manner as described for wool, but requires stronger vats and longer dips to obtain the same depth of colour.
(2) INDIGO EXTRACT FOR BLUE
Dye at a temperature of 40 to 50°C. with as much Indigo Extract dissolved in the bath as is required for the desired depth of shade. If the silk has been first mordanted with alum, compound colours can be obtained by the addition of a red or yellow dye to the bath.
(3) CRIMSON
Mordant with Alum or Aluminium Acetate and dye with 40 to 50 per cent Cochineal. A teaspoonful of Tin, dissolved in cold water, may be added to brighten. Boil well. It is advisable to wash in soap after using tin as it prevents the latter making the yarn brittle.
(4) MADDER RED
Mordant with Alum or Aluminium Acetate. Dye with 80 to 100 per cent Madder and a handful of bran per pound of silk. Bring slowly to the boil in 1 hour, boil a few minutes. It should be brightened by boiling a short time in soap, with a little tin.
(5) YELLOW
Mordant with Alum or Aluminium Acetate. Various Dyes may be used. Weld: Dye with 150 per cent. Flavin: Dye with 1 oz. to the pound, with a teaspoonful Tin. Fustic: Dye with 50 per cent, or more. Quercitron: Dye with 10 to 20 per cent. A little chalk may be added towards the end.
The shades may be varied by the addition of small quantities of madder or cochineal. Orange may be obtained by the use of Madder, 2 to 4 ozs. per pound, with Flavin or Fustic.
(6) GREEN
Greens may be obtained by dyeing with any of the yellow dyes and blueing in the Indigo Vat or with Indigo Extract. If the colour is thin, it should be dyed a deeper blue in the vat and then re-dyed with yellow. A strong clear yellow is needed for a good green.
(7) PURPLE
Dye silk blue in Indigo Vat. Then dye without mordanting in Cudbear.
