Kirkpatrick [57 ABSTRACT A cabled yarn, suitable for use in Moresque-type carpets, comprising at least two sets of ends of yarn, each set comprising at least two ends of yarn, corresponding ends of yarn of each set having the same visual characteristics. The ends of yarn of at least one of the sets have a number of turns per inch which is not a whole number multiple of the number of turns per inch of the ends of yarn of any other of the sets, at least one of the sets comprising ends of yarn which are plytwisted with respect to each other.
4 Claims, 7 Drawing Figures PATENIED 8E? 12 m2 FEGE' FIG 4 FIGS FIG 6 CABLED YARN This invention relates to cabled yarn and, more particularly, to a cabled yarn especially suited for use in Moresque-type carpets.
It is a principal object of the present invention to produce a cabled pile yarn that will yield a Moresquetype carpet that is substantially free from striae efiects, streaks, or other undesirable concentrations of one of the various colors of the carpet. Other objects include substantially reducing a percentage of manufactured carpets that must be rejected as imperfect, or sold as seconds because of such defects.
It has been found that these objects can be achieved in a cabled yarn comprising at least two sets of ends of yarn, each set comprising at least two such ends. Corresponding ends of yarn of each of the sets are chosen to have the same visual characteristics (e.g., color, texture, etc.). The ends of yarn of at least one of the sets in the cabled yarn have a number of turns per inch which is not a whole number multiple of the number of turns per inch of the ends of yarn of any other of the sets. Furthermore, at least one of the sets comprises ends of yarn which are plytwisted with respect to each other prior to being cabled with the other sets. Should more than one of such sets be so preliminary plytwisted prior to cabling, it is required that the twist (conventionally referred to as S twist or Z twist) of each such set be in the same direction.
Other objects, features, and advantages of the invention will appear from the following detailed description of preferred embodiments, taken together with the attached drawings in which:
FIGS. 1 and 2 illustrate sets, in this case pairs, of preliminarily plytwisted ends of yarn;
FIG. 3 illustrates a cabled yarn according to the invention formed by cabling the sets or pairs illustrated in FIGS. 1 and 2;
FIG. 4 illustrates a pair of preliminarily plytwisted ends of yarn to be employed in an alternative cabled yarn according to the invention;
FIGS. 5 and 6 illustrate single ends of yarn to be employed in the alternative embodiment of FIG. 7; and
FIG. 7 illustrates the alternative embodiment of a cabled yarn formed by cabling the pair of FIG. 4 with the single ends of yarn of FIGS. 5 and 6.
Referring to the first embodiment shown in FIGS. 1, 2, and 3 of the drawings, the cabled yarn 17 of FIG. 3 consists of four ends of yarn 10, 12, 14, and 16. These ends of yarn may be viewed as two sets, each having two ends of yarn. Thus, ends of yarn 10 and 12 are the first set and ends of yarn 14 and 16 are the second set. As is evident from FIG. 3, ends of yarn 10 and 12 have a number of turns per inch in the final cabled yarn which is greater than the number of turns per inch of ends 14 and 16. This is achieved, as shown in FIGS. 1 and 2, in this particular embodiment by preliminarily plytwisting the ends of each set to make plytwisted pairs having differing numbers of plytwists per inch. According to the invention, it is important that the number of turns per inch, in the ultimate cabled yarns, of one set of ends be other than a whole number multiple of the number of turns per inch of the second set.
It should also be noted, regarding the embodiment of FIGS. 1-3, that the preliminary plytwisting of the sets of ends of yarn involves giving each set the same direction of twist (S twist in the embodiment illustrated).
Corresponding ends of yarn of each of the two sets should have the same visual characteristics (e.g., color, texture, etc.). This is most simply achieved, of course, by employing the same varieties of yarn in each of the two sets. Thus, for example, in FIGS. 1 and 2 ends 10 and 14 may be the same variety of yarn and ends 12 and 16 may be the same variety of yarn.
As a specific example of this embodiment, ends of yarn 10 and 14 may be color A and ends 12 and 16 color B. Ends 10 and 12 are S plytwisted at 2.50 turns per inch (t.p.i.) and ends 14 and 16 are S plytwisted at 1.95 t.p.i. The 2.50 t.p.i. S yarn and the 1.95 t.p.i. S yarn are then cabled at 0.75 t.p.i. S. Since 2.50 is not a whole number multiple of 1.95, the relationship of the ends within one set to the ends in the other set will change continuously in the cabled yarn. Concentrations of color are, therefore, avoided.
In the alternative embodiment of FIGS. 4-7, once again four ends of yarn 18, 20, 22, and 24 are provided in a cabled yarn 26 wherein ends 18 and 20 have a different number of turns per inch than ends 22 and 24. Once again ends 18 and 22 and ends 20 and 24 may be yarns of the same varieties. In this embodiment, however, only one set (i.e., the set comprising ends 18 and 20) is preliminarily plytwisted, as indicated in FIG. 4. Although the single ends 22 and 24 (see FIGS. 5 and 6) may have, as is conventional, a small amount of twist to merely provide a stable yarn which may be easily ham dled, they are not preliminarily plytwisted prior to the cabling operation. By cabling the three elements shown in FIGS. 4, 5, and 6 together with a number of turns per inch which is other than a whole number multiple of the number of turns per inch in the plytwisting of ends 18 and 20, a cabled yarn which achieves the desired random color distribution will be produced.
As a specific example of this embodiment, ends 18 and 22 may be color A and ends 20 and 24 may be color B. Ends 18 and 20 are S plytwisted at 1.0 t.p.i. The 1.0 t.p.i. S yarn and the single ends 22 and 24 are then cabled at 1.5 t.p.i. S. The ultimate cabled yarn (FIG. 7) will then have one set of colors A and B with 1.5 t.p.i. of S twist and another set of colors A and B with 2.5 t.p.i. ofS twist.
In all embodiments, it is preferred that the cable twist be from 0.5 t.p.i. to 3.0 t.p.i. Although twists greater than 3.0 t.p.i. are usually unsatisfactory (e.g., too lean and/or kinky), for special effects greater values may be suitable.
What is claimed is:
1. A cabled yarn comprising at least two sets of ends of yarn, each set comprising at least two ends of yarn, corresponding ends of yarn of each set having the same visual characteristics, the ends of yarn of at least one of said sets in said cabled yarn having a number of turns per inch which is not a whole number multiple of the number of turns per inch of the ends of yarn of any other of said sets, at least one of said sets comprising ends of yarn which are plytwisted with respect to each other.
2. A cabled yarn as claimed in claim 1 in which a plurality of said sets comprise ends of yarn which are plytwisted with respect to each other, each said plytwisted set having the same twist direction.
3. The cabled yarn as claimed in claim 2 wherein all of said sets of ends of yarn comprise ends of yarn which are plytwisted with respect to each other.
4. A cabled yarn as claimed in claim 1 wherein there is only one of said sets which comprises ends of yarn which are plytwisted with respect to each other.
