The Dyeing of Cotton Fabrics: A Practical Handbook for the Dyer and Student
Beech, Franklin
Dyes and dyeing -- Cotton
Very little difficulty will be met with in dyeing such light fabrics as
Italians, cashmere, serges and similar thin textiles lightly woven from
cotton warp and woollen weft. When deep shades (blacks, dark blues,
browns and greens), are being dyed it is not advisable to make up the
dye-bath with the whole of the dyes at once. It is much better to add
these in quantities of about one-fourth at a time at intervals during
the dyeing of the piece. It is found that the affinity of the wool for
the dyes at the boil is so much greater than is that of the cotton that
it would, if the whole of the dye were used, take up too much of the
colour, and then would come up too deep in shade. Never give a strong
boil with such fabrics, but keep the bath just under the boil, which
results in the wool dyeing much more nearly like to cotton.
_Bright Yellow._--Use 2 lb. Thioflavine S in a bath which contains 4 lb.
Glauber's salt per 10 gallons of dye liquor.
_Good Yellow._--A very fine deep shade is dyed with 2-1/2 lb. Diamine
gold and 2-1/2 lb. Diamine fast yellow A, in the same way as the last.
Here advantage is taken of the fact that while the Diamine gold dyes the
wool better than the cotton, the yellow dyes the cotton the deeper
shade, and between the two a uniform shade of yellow is got.
_Pale Gold Yellow._--Use a dye liquor containing 4 lb. Glauber's salt in
every 10 gallons, 2-1/2 lb. Diamine fast yellow A, 2 oz. Indian yellow G
and 3-1/2 oz. Indian yellow R. In this recipe there is used in the two
last dyes purely wool yellows, which dye the wool the same tint as the
fast yellow A dyes the cotton.
_Bright Yellow._--Use in the same way as the last, 2-1/2 lb. Diamine
fast yellow B and 3 oz. Indian yellow G.
_Gold Orange._--Use as above 2 lb. Diamine orange G, 5-1/2 oz. Indian
yellow K and 1-1/2 oz. Orange E N Z.
_Deep Orange._--Use 2-1/2 lb. Diamine orange D C, 6-1/2 oz. Orange E N
Z, and 3-1/4 oz. Indian yellow R.
_Black._--Use 4-1/2 lb. Union black S, 2 oz. Diamine fast yellow A, 5
oz. Naphthol blue black and 3-1/4 oz. Formyl violet S 4 B, with 4 lb.
Glauber's salt in each 10 gallons dye liquor.
_Navy Blue._--Use 1-1/4 lb. Union black S, 3 lb. Diamine black B H, 1/2
oz. Naphthol blue black, 1/2 lb. Formyl violet S 4 B and 2-1/2 oz.
alkaline blue B.
_Red Plum._--Use a dye-bath containing 2-1/2 lb. Oxydiamine violet B and
3-1/4 oz. Formyl violet S 4 B.
_Dark Green._--A fine shade can be dyed in a bath containing 3 lb.
Diamine green B and 1-1/2 lb. Diamine black H W.
_Dark Slate._--Use 4 lb. Diamine black H W, 2 oz. Naphthol blue black
and 3 oz. Azo red A.
_Sage._--Use a dye-bath containing 4 lb. Diamine bronze G and 1-1/4 oz.
Naphthol blue black.
_Dark Brown._--A fine dark shade is got from 2-1/2 lb. Diamine brown V
and 2 oz. Naphthol blue black.
_Peacock Green._--Use 3-3/4 lb. Diamine steel blue L, 13 oz. Diamine
fast yellow B, 14-1/2 oz. Thiocarmine K and 2-1/4 oz. Indian yellow G in
a bath of 4 lb. Glauber's salt per gallon dye liquor.
