283. To Dye Mixed Fabrics Two Colors.

Mixed fabrics of cotton and wool, such as coburgs, damasks, &c., may be dyed all of one color, or the cotton and wool in them each dyed a different color. This is seldom done except with new goods, or with very light colored goods which are desired to be dyed dark colors. As the process for dyeing woolen swill seldom impart the same color to cottons, the two are dyed separately, and the method is quite simple. For most colors it is necessary to dye the woolen portion first, and then the cotton; but in a few cases the cotton must be the first to be acted on.

284. Green and Pink.

First dye the woolen green by either of the methods given in Nos. 206, 207, &c. The cotton is then dyed pink, according to receipt No. 248.

285. Green and Crimson.

Dye the woolen by working for an hour in 2 pounds tartar, 4 pounds alum, and 6 pounds fustic; lift, and add 4 pint indigo extract (see No. 99); wash out, and lay over night in 6 pounds sumach; then work for 30 minutes in red spirits (see No. 108) made to a strength of 1½° Baumé wash out, and work for an hour in 5 pounds peachwood at blood heat; lift, and add a little alum; work in this, then wash out and finish.

286. Blue and Orange.

First dye the cotton by the blue vat (see No. 130), wash out, and then dye the woolens by working an hour in a bath made up of 2 pounds tartar, 8 ounces cochineal, 2 pounds fustic, and 2 pints bichloride of tin; wash and dry.

In this way almost any two colors may be dyed upon woolen and cotton, although woven together, by proceeding according to the receipt for the color required on each sort of fibre. The wool is always dyed first, excepting in the case where the cotton is dyed in the blue vat, when the cotton has to be treated first. The same principle is applicable to silk and woolen fabrics, although in many cases the silk becomes more imbued than the cotton by the woolen dyes. A mixture of silk and cotton can be dyed in tho same manner, but it is much more difficult, and cannot be done with all kinds of colors, and the process is seldom resorted to. But the intelligent dyer will be able to combine a variety of tints by following the rules and receipts given.
