KNITTING

The art and process of forming fabrics by looping a single thread, either by hand with slender wires or by means of a machine provided with hooked needles, is called knitting. Crocheting is an analogous art, but differs from knitting in the fact that the separate loops are thrown off and finished by hand successively, whereas in knitting the whole series of loops which go to form one length or round are retained on one or more needles, while a new series is being formed on a separate needle. Netting is performed by knotting threads into meshes that cannot be unraveled, while knitting can be unraveled and the same thread applied to any other use. Knitting is really carried on without making knots; thus, the destruction of one loop threatens the destruction of the whole web, unless the meshes are reunited.

The principle of knitting is quite distinct from that of weaving. In the weaving of cloth the yarns of one system cross those of another system at right angles, thus producing a solid, firm texture. The great elasticity of any kind of texture produced by knitting is the chief feature that distinguishes hosiery from woven stuffs. The nature of the loop formed by the knitting needle favors elongation and contraction without marring in the least the general structure of the goods. Builders of weavers’ looms have at times endeavored to secure this elastic effect by certain manipulations of the mechanism of the loom, but as yet nothing approaching the product of the knitter has been made. The elastic feature of a knitted texture renders it peculiarly adapted for all classes and kinds of undergarments, for it not only fits the body snugly, but expands more readily than any other fabric of similar weight.

Knitting Machines. There are various machines for knitting. The circular knitting machine produces a circular web of various degrees of fineness, and in sizes ranging from a child’s stocking to a man’s No. 50 undershirt. The circular fabric made in this manner has to be cut up and joined together by some method to make a complete garment. The knitting frame for producing fashioned goods makes a flat strip, narrowing and widening it at certain places so as to conform to the shape of the foot, leg, or body. These strips then have to be joined by sewing or knitting to form a garment. Fashioning machines are indispensable for knitting the Niantic and French foot, and also for the production of stripes, fancy openwork, and lace hosiery.

KNITTING MACHINE FOR HOSIERY

All plain machines of any class produce only plain knitted fabrics, while ribbed machines make only ribbed fabrics. Still, many garments in their make-up include both kinds of knitting; therefore, many machines produce only certain parts of particular garments. In the case of half-hose there is frequently a ribbed top, or in

underwear a ribbed cuff, and these may be made either of circular web or full fashioned. In each case the ribbed portion is first knit and then transferred to a plain machine, and being placed upon the needles is worked on to the rest of the garment. In some instances the heel is made by the machine working the leg, though there are numerous knitters specially designed for turning out only this particular part.

Among other knitting machines in modern use are the drawers machine; machines for hose and half-hose with apparatus for making the instep, finishing off the toe, splicing or thickening the heels, etc.; machines for producing the bottoms or soles of hose separately, and also the instep separately; circular stocking machines for producing a tubular web afterwards cut into suitable lengths for all varieties of hose; circular sleeve machines, circular body machines, as well as circular web machines for making both body and sleeves of undershirts, jerseys, sweaters, etc. Special machines are also made for knitting both plain and ribbed plaited goods, that is, with both sides wool while the center is of cotton, or with a silk or worsted face on one side and the back of an inferior yarn. In the form of auxiliary appliances are produced many kinds of stitching machines; circular latch-needle machines for plain ribbed, mock seam, and striped goods; steam presses; hose rolling machines; hose cutting and welting machines, and many other accessories to hosiery manufacture.
