Serial 1V0. 576,815.

This invention relates to finely knitted wearing apparel, articularly to hosiery, and to the sllk or synt etic yarns used in its production.

The prime requisites of fabric quality and appearance in finely knitted a parel such as ladies hosiery, are elasticity, s eerness, firmness and strength, combined with a rich dull luster finish. High-twist yarns, such as grenadine, crepe, compensene, etc., have heretofore been utilized in this branch of the knitting art because each, in a limited way, imparts one or more of these desirable characteristics to finely knitted fabrics. In general, however, these yarns are not satisfactorily suited to this purpose for several reasons. Chief among these may be mentioned their limited contribution to the essential requisites of the finished fabric, and their unavoidable high production cost due to invoived and extensive twisting Clue object of my invention is to provide a novel yarn more ideally adapted for this purpose in that it not only imparts to lmitted wearing apparelall of the mentioned essential requisites, but enhances or intensifies the latter, and which, due to its construction, can be more quickly and easily produced at a fraction of the cost of the heretofore used high-twist yarns.

i attain these results in the manner disclosed by the following detailed description and accompanying drawingof severalillustrative embodiments of the invention, reference to which will make the above and other objects, as well as attendant advantages, more readily apparent.

- the drawing 2- Fig. l is a side elevational view of a stocking, and illustrates one knitted article embodying my invention; the usual loop formation of the improved knittedfahric being inicated on a greatly enlarged scale.

Fi s. 2, 3 and 4 illustrate various forms of my novel yarn.

In accordance with my invention, the intensification of the desirable characteristics above ointed out, is attained in a knitted fabric oy the use of a yarn in which twisted and nntwisted filaments or strands are comgree of Sheerness, quality and fine appearance.

Considering the yarn in its broader aspects,

the twisted and untwisted strands are united as follows: One or more of the constituent strands are first given acomparatively high twist in one direction, these are then combined with one or more untwisted'strands, and this combination is united by a final twisting-together in the direction opposite to that of the twist of the first mentioned strands. Preferably, although not necessarily, the proportion of twisted strands to untwisted strands is such that the latter are in the majority.

. In comparison with the construction of the above mentioned high-twist yarns the amount of twisting involved in my novel yarn is, therefore, considerably less. F urthermore, the hardness and harshness of such yarns is overcome by the presence of the softer untwisted strands. The latter also impart a desirable amount of glow to the stockings which has the well known slen derizing effect on the leg of the wearer; and finally make the yarn knit better.

- The degree of intensity, particularly as to the depth and richness of the dull-luster effect of the knitted fabric, can, of course,

be varied within wide limits by varying the twists and proportion of twisted to untwisted strands.

In the following description of several practical forms of my novel yarn, I shall, for

convenience, refer to the untwisted strands -as comprising group A, and the twisted improved yarn shown, mainly illustrate possible variations in the number and twisting of the strands in group B, and the final twist imparted when uniting groups A and B to form the yarn Y.

Specifically considering the yarn Y of Fig. 2, the single strand 5, comprising oup B, is twisted approximately thirty-six turns per inch to the right and combined with three untwisted/strands 6, 7 and 8 comprising group A; both groups A and B being unitedly-twisted to the left about thirty-two turns per inch.

The yarn Y of Fig. 3, is composed of three untwisted strands 9, 10 and 11 in group A,

two strands 12-and 13 in group B twisted approximately thirty turns per inch to the right, and both groups A and B unitedlytwisted to the left at the rate of about twentyseven turns per inch.

In Fig. 4, group A consists of three untwisted strands 14, 15 and 16; grou B of two strands 17 and 18 first individually twisted approximately sixty turns per inch to the right and then combined by united-twisting to the right; groups A and B being finally twisted together at the rate of about twentyseven turns per inch to the left to form the yarn Y.

It is to be understood that the limits of twist specifically iven in these three instances for the in ividual strands forming group B, and also for the uniting twist given all the strands comprising the yarn, is somewhat elastic and depends on the intensity of g the characteristics of quality and appearance desired.

The yarn Y is knitted into a fabric in the usual and well known manner, one desirable loop formation being illustrated in Fig. 1; such knitted fabric incorporating the intensified characteristics of qualit and appearance above pointed out. Obvlously, knitted lace fabrics are similarly enhanced if produced with this yarn.

Of course, the improvements specifically sfi wn and described can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.

I claim: 1. A knitting arn composed of two on s one direction, one of said groups inclu ing one or more untwisted strands, and the other group includin one or more strands individually twiste in the direction opposite to said united-twisting.

2. A knittin yarn composed of two groups of strands com med by a comparatively high united-twisting in one direction, one of said groups including one or more untwisted strands, and the other group including one or more strands individually given a comparatively high twist in the direction opposite to said united-twisting.
