This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...the dye liquor, and dilution of the latter is thus avoided during dyeing. Fig. 11 illustrates a vat in which the pieces, in rope form are drawn as an endless band in a spiral over the same winch a large number of times after remaining in the liquid for a short time. Guide pegs prevent them from becoming entangled. The machine most frequently met with in the dyeing of cotton cloth is the jigger. In this machine the cloth in full width is passed through the dye liquor several times over guide rollers. In Fig. 12 two of these rollers, alt a, are shown submerged in the liquid, and three, bt b2, bs, are placed above. In addition, two draw rollers, cu c, and two batch rollers, rf, and d2, are visible above the vat. The cloth is first run from to r2, the roller c2 being actuated directly by the driving machinery, while the brake e is placed on cx. The cloth is thus kept in a state of tension. When all the cloth has been run on to c.ly the motion is reversed, being made the driving roller, and the brake being put on r2. This alternate motion is continued until the piece has been dyed the desired shade. The pipes necessary for the supply of water and steam for heating are indicated in Fig. 12a. For indigo dyeing', pp. 49 and 100, vats are employed in which the cloth is run over a large series of rollers completely submerged in the liquor. It then passes through squeezing rollers, and over a series of rollers placed in the air above the vat for the purpose of oxidising the leuco compound absorbed by the fibre. Another arrangement shown in Fig. 13 for the purpose of oxidising the leuco compound, consists in piling the cloth loosely on an endless travelling band. The dye vat must be supplied with a stirring arrangement G, which can be...
