FRIZING of cloth, a term in the woollen manufacture, applied to the foyminglof the nap of cloth, or stuff, into a number of little hard burrs or prominences,covering almost the whole ground thereof. Some cloths are only frized on the back side, as black cloths ; others on the right side, as coloured and mixed cloths, rateens, bays, frizes, &c. Frizing may be per formed two ways; one with the hand, that is, by means of two workmen, who con duct a kind of plank that serves for a frizing instrument.
The other way is by a mill, worked ei their by water, or a horse, or sometimes by men. This latter is esteemed the bet ter way of frizing, by reason, the motion being uniform and regular, the little knobs of the frizing are formed more equably and regularly. The structure of this useful machine is as follows : The three principal parts are the frizer or crisper, the frizing-table, and the drawer or beam. The two first are two equal planks, or boards, each about ten feet long, and fifteen inches broad, differ ing only in this, that the frizing-table is lined or covered with a kind of coarse woollen stuff, of a rough sturdy nap ; and the frizer is incrustated with a kind of ce. ment composed of glue, gum arahic, and a yellow sand, with a little aquavitx, or urine. The beam, or drawer, thus called because it draws the stuff from between the frizer and the frizing-table, is a wood en roller: beset all over with little, fine, short points, or ends of wire, like those of cards used in carding of wool.
The disposition and use of the machine is thus : the table stands immoveable,and bears or sustains the cloth to be frized, which is laid with that side uppermoston which the nap is to be raised : over the table is placed the frizer, at such a dis tance from it as to give room for the stuff to be passed between them, so that the frizer, having a very slow semicircularrno tion, meeting the long hairs or naps of the cloth, twists and rolls them into little knobs or burrs, while, at the same time, the drawer, which is continually turning, draws away the stuff from under the fri zer, and winds it over its own points.
All that the workman has to do while the machine is going is, to stretch the stuff on the table, as fast as the drawer takes it off ; and from time to time to take off the stuff from the points of the draw er. The design of having the frizing-ta ble lined with stuff of a short, stiff, stub by nap, is, that it may detain the cloth be tween the table and the frizerlong enough for the grain to be formed,that the draw er may not take it away too readily, which must otherwise be the case, as it is not held by any thing at the other end.
