This invention relates to a woven fabric and appearance. In conventional sharkskin, haVa. more particularly to a fabric woven with Woolen ing alternate dark and light shade worsted yarns yarn, with worsted yarn, with yarn containing a . in both the warp and the weft, the manufacturer mixture of wool with other fibres, or with a com meets a serious problem in the matter of rejects. bination of such yarns, which has a predominant 5 All worsted or woolen yarns vary so in size due to dark diagonal visual effect of the type distinctive spinning or other variations inherent in the yarn to sharkskin worsted and sharkskin cheviot fab manufacture, that, when woven into a fabric, a rics. The fabric of this invention has, in gen light or dark colored yarn in a portion of a pick or eral, the appearance of a conventional sharkskin in a portion of a warp will stand out, and so fabric, although the distinctive sharkskin fea 0 catch the eye in contrast to a dark or light col tures are not as pronounced as in ordinary shark ored adjacent yarn that the even appearance of skin fabric.

Since, however, their occurrence is use as a substitute for sharkskin fabrics. - 15 almost completely unavoidable, conventional Ordinary worsted and cheviot sharkskins are sharkskin rejects may run high and usually ex used extensively in the fabrication of men's suit ceed 5% of a total production.

As will be seen, where a weft yarn of a The individuality of sharkskin is inherent in the single shade is utilized, as in the fabric of this fabric and is dependent upon the particular com invention, imperforations of the type just enum bination of a certain weave with a certain warp erated will be entirely obviated so far as the weft and weft design. The weave, is a two-and-two is concerned, thus reducing by half the possi twill and the warp and weft design results from bility of unevenness in appearance. As a mat interweaving alternate dark and light weft ter of fact, it has been found that the uniformity. threads with alternate dark and light.

The fab ventional sharkskin is its superior uniformity of 55 ric, then, in its simplest form, is a three-shade 2 2,253,374 fabric as distinguished from a conventional two diagonals both give the effect of blends, one of shade or four-shade sharkskin and has therefore which, A-A, being a composite of the dark and in certain of its aspects a different appearance intermediate shade yarns only, gives a total effect from conventional sharkskin fabric, though the equivalent to a shade just under dark, and the difference in appearance is not as pronounced as other of which, B-B, being a composite of light the similarity. and intermediate shade yarns only, gives a total Preferably, as in conventional sharkskin, the effect equivalent to a shade slightly darker than Warp yarns are of two different shades. Under light. Obviously, the contrast between diagonals Such circumstances, the single shade weft yarn A-A and B-B is much greater than any con may be of the same general color as both the O trast between diagonals C-C and D-D.

In this drawing, and to conventional sharkskin. V the vertical yarns represent warp yarns and the . As will be understood, a fabric could be woven horizontal yarns represent weft yarns. Thus, the which would have a right-handed "staircase" warp yarns include a set of light Warp yarns 0 20 effect by making suitable variation in the type of interspersed alternately with dark warp yarns 20 two-and-two twill weave utilized.

Of course if plaid fill fabrics of this invention. In addition, white plus ing is desired, an automatic box loom or similarly two shades of blue, brown, green, respectively, acting loom will be necessary. etc., may be employed. Thus, in each case, the 35.
