Bandanas, Or Bandannas. This name, originally applied to a peculiar kind of silk handkerchief made by the Hindoos, is now given to silk and cotton handkerchiefs manufactured in this country decorated with patterns of similar character, though by a very different process. A bandana handkerchief has a dyed ground, usually of bright red or blue, ornamented with circular, lozenge-shaped, or other simple figures, either white, or, in some cases, of a yellow colour. These spots are said to be produced, in real Indian bandanas, by tying up the parts intended to be white or yellow with bits of thread before exposing the hankderchief to the action of the dye, and thus protecting them from it. In the process followed by British manufacturers, which was invented in 1810 by M. Kochlin, of Mulhausen, the whole surface of the handkerchief is dyed of one uniform colour; a number of pieces thus dyed are laid between two leaden plates, perforated with holes wherever white spots are intended to be, and while the several thicknesses of cloth are compressed in this manner by the power of an hydraulic press, a fluid capable of discharging the dye is caused to percolate through the holes in the leaden plates, removing, in its passage, the dye from such parts of the cloth as are exposed to its action. By varying the discharging fluid the spots may be made yellow instead of white; and arrangements are sometimes made for combining white and yellow spots in the same handkerchief.
