Abstract
Abstract The method herein is used to achieve the combination frieze and saxony visual with the use of one yarn. Conventional slub yarns are plied and twisted with a high twist. The large diameter portions of the yarn force additional twist into the small diameter portions causing them to be greatly twisted. The large diameter sections remain relatively straight. The yarn character is set, and then this is tufted into a carpet backing. This provides a combination frieze and saxony effect in the finished product.

The method of forming a carpet with a combination frieze and saxony visual effect, comprising the steps of, forming a conventional slub yarn which has sections of the yarn with a large diameter relative to other sections of the yarn which are of a relatively small diameter, said diameter relationship being established by the difference in the diameters and yarn weight of the individual sections which form the slub yarn, additionally twisting the slub yarn to a very high twist to place additional twist into the slub yarn, permitting the additional twist in the large diameter sections of the slub yarn to be transmitted by the yarn to the small diameter sections of the slub yarn so that the large diameter sections of the slub yarn are relatively free of the additional twisting and the small diameter sections of the conventional slub yarn are greatly twisted and the yarn as a whole tends to twist about itself, setting the twist within the yarn, and then tufting the yarn into a carpet backing to form tufts which are either tightly twisted together and curled, or relatively loosely twisted together and straight, said highly twisted sections of the conventional slub yarn forming the tightly twisted and curled tufts, whereas the relatively untwisted sections of the conventional slub yarn form the lightly twisted and straight tufts whereby the tightly twisted and curled tufts provide a frieze visual effect and the relatively untwisted straight tufts provide a saxony visual effect.
