To obviate this danger as far as possible each man opens the fleeces on a table covered with wire screen, under which circulates a strong exhaust current of air which is mechanically generated. Thus small foreign particles and dust in the fleeces are drawn downward. When the fleece is opened the sorter selects that part of the fleece which is known to be the coarsest, _i. e._, the breech and a strip along the center of the back, and puts this in one lot. Next he selects a narrow strip along the side of the fleece, which is known to be the finest part of the fleece, and puts this in another lot. Now the neck and the belly are separated and thrown into their classes. If the whole fleece were a fine one, and free from kemp, it would be sorted in the same way, but different parts of the fleece would go into proportionately higher classes. The lots which these sorters make are known to spin comparatively definite qualities of yarn. Thus the low breech and the back of most fleeces will not spin over No. 20 to No. 24 yarns, and the sides of good fleeces are fine in fiber and will spin No. 40 to No. 60 yarn. The quantity of mohair which one man can sort varies considerably, according to the class of mohair which he is given to work upon. One mill estimated that experts can sort between two and three hundred pounds of domestic mohair a day, and that it costs about a cent a pound to thus separate the fleece. After the fleeces are graded, the mohair is ready to be sent to the mill proper for scouring and spinning. SCOURING. To-day the process of washing or scouring the fleece is done by machinery. The mohair is fed into a machine in which revolve paddles, which thoroughly mix the fiber with the liquid in this machine. At the opposite end from where it was fed in, the mohair is rolled out over warm rollers, and it is ready to be spun. It is claimed, and with some justice, that American mohair loses or shrinks about 12% to 20% while passing through this washing machine, and that Turkish mohair only shrinks about 13%. This may be due to the fact that some of the Turkish hair had been washed before it was shipped to market, and that by previous sorting some of the dirt had fallen out of the mohair. Then, too, some of the American growers are not very careful to keep the fleeces clean. Straw, sticks, hats, and even stones have been found in some domestic stuff. MIXING. After the mohair is thoroughly cleaned it is ready for spinning or carding. In order to spin the fibers most economically, evenly and to the best advantage, some of the mills mix different qualities of mohair of about the same fineness. For instance, Turkish mohair is mixed with Texas and California stuff, or Oregon is mixed with Iowa material. The spinning qualities of mohair from different sections varies, and this mixing tends to give uniformity. After the fibers have been mixed to suit, the mohair is run through straightening machines in preparation for the combing process.
