C42 CALICO-PRINTING 



next through the highest rollers, and BO on into the flue, the course being easily 

 traced by the arrows ; on leaving the flue dry, they are wound on a beam, or plated 

 down on the wooden platform behind the machine. The 3 rollers of the padding- 

 machine are made of brass, and are wrapped with a few folds of calico ; the iron 

 journals of them work iu slots, the lowest ono being at the bottom of the slot working 

 in brass bearings ; a weighted lever presses the top roller in forcible contact with the 

 others. Another method of padding, and one now becoming very generally adopted, 

 is, to dispense with the flues as above described, and, after padding, to dry the pieces 

 over an ordinary cylinder drying-machine, the cylinders of which are covered with 

 woollen printing blanket. 



Padded goods after printing in acid are passed through the ageing-machine, and 

 after lying all night are dunged and dyed. A few of these shades are here given. 



a. Claret and white. Pad in red liquor, at 10 T., dry, cool, and pad again in same 

 liquor, dry, cool, and print in acid No. 37, age three nights. Fly-dung at boil, wash, 

 second dung at 160 F., hour, wash, dry, and singe, wash and dye 12 pieces 7 ft. 8 in. 

 30 yards with 18 Ibs. ground peach wood, 21 Ibs. of French madder, 5 Ibs. sumac, 5 Ibs. 

 prepared logwood, run the pieces in the beck cold for 20 minutes, and then bring to 

 a boil in 1 hour and 10 minutes, boil 15 minutes, get out, rinse and wash, bran 10 

 minutes at boil in a beck with a few pounds of bran, rinse in a pit, and bran again at 

 boil, wash and dry. 



Prepared logwood is thus made. Ground logwood is spread out on a floor, damped 

 with water, -vnd heaped up. It is then turned over once a day for a fortnight and 

 occasionally wetted, during which time it changes from a dull red to a bright scarlet. 

 It is then ready for use. Some change, probably oxidation, has taken place, and the 

 wood dyes further after this process. 



b. Scarlet and white. Padded and dunged as for clarets ; then 10 pieces dyed with 

 15 Ibs. French madder, 15 Ibs. Dutch crop madder, 7 Ibs. peach wood, 4 Ibs. sumac
