United States Patent O CURLED YARNS, CURLnn YARN FABRICS AND MErHoD FoR MAKING SAME William Rollin Keen, Media, Pa., assignor to Collins & Aikman Corporation, Philadelphia, Pa., a corporation of Delaware Application April 3, 1956, Serial No. 575,754 17 Claims. (Cl. v28-72) This invention relates to a method of manufacturing curled or crimped textile yarns, curled yarn fabrics, to the apparatus for 'making them, and to the curled yarns produced thereby. The curled yarns of the present invention may be made from fibers or laments of materials which will take a substantially permanent set such as mohair, wool, nylon, dacron and the like or mixtures thereof with viscose or lthe like.
It has been known to produce curled or crimped yarns for use in textile materials. However, the known methods are both tedious and costly and 'often produce serious deterioration in the strength and elasticity of the yarns produced so that they are diliicult and costly to use in weaving or Vother fabric forming processes.
It is -an object of this invention to provide a method of crimping or curling textile yarns without injuring the yarn material.
Itis also an object of this invention to provide a rapid and inexpensive method for continuously producing curled textile yarns.
It ,is Va further object of the present invention to provide a continuous process for crimping `or curling yarns without exert-'ing undue strain on the yarn material.
It is also an object of this invention to provide a process and apparatus for producing fabrics having curled or crimped yarns.
`It is a further object fof .the present invention tor provide a process and apparatus for continuously producing a number of curled yarn ends and simultaneously Weaving or tufting a fabric using said ends.
It is a still further object of this invention to provide a novel crimped or curled textile yarn.
One embodiment of the invention is illustrated in the attached drawings of which:
Fig. l is a perspective view of a backing material tufted with a yarn which it is desired to curl or crimp in accordance with the invention;
Fig. 2 is a perspective view of the tufted yarn of Fig. 1 removed from the backing material;
Fig. 3 is a perspective view of the crimped yarn of Fig. 2 employed as a pile yarn in a woven cut pile fabric; and
Fig. 4 is a diagrammatic drawing showing another embodiment of the invention wherein a pile yarn is tufted in a backing material, `set in the backing, removed and then retufted in the backing material and showing the apparatus employed;
Fig. 5 is a diagrammatic drawing showing another embodiment of the invention wherein an endless loop of backing material is continuously tufted and the tufted yarn is set and spooled; and
Fig. 6 is a diagrammatic perspective view showing another embodiment of the invention wherein an endless loop =of backing material is continuously tufted, and the tufted yarn is set and beamed to a loom.
The yarn 10 which it is desired to curl or crimp is tufted in the usual manner in a backing material 11 as 2,857,651 Patented Oct. 28, 1958 shown in Fig. l. The backing material may be of any of the usual open weave materials such as burlap. The yarns itl may be of any normal construction as to count or twist in the single or ply and may be spun entirely of wool, mohair, nylon, dacron or any settable fiber or lilaments of nylon or any settable filament or combinations thereof. The yarn '10 is tufted in the backing 11 and, as thus deformed, is subjected to the treatment necessary to provide a set in the yarn 10. The type of crimp or curl produced in the yarn may be varied by modifying types of loops and stretch used during the tufting. The setting is `performed lon the tufted fabric in accordance with known methods required to produce a set in the yarn material such as by the application of hot water -or steam. lf preferred, the tufted yarn may be dyed while in this condition vand thereby obtain `both setting and dyeing at the same time. The yarn V,is then pulled from the backing as may be easily done with a tufted yarn, and is fully prepared to be used as za pile yarn in a tufted or woven fabric. A fully crimped -and set -yarn 12 is shown in Fig. 2 and Fig. 3 shows the crimped yarn 12 woven as the pile yarn in a pile Yfabric 13. As shown in Fig. 3, the pile -is Vcut allowing the yarns 12 to twist or -turn in accordance with their set conformations to form a dense, tight, `pile surface.
A continuous process for making crimped yal-nis shown in Fig. 5. Backing material 30, which lmay `be in the form .of a continuous loop, is continuously fed into a tuftingmachine 31 where itis tufted With yarn 32.
The tufted backing material 30 .is then lcontinuously fed' into a setting chamber 33 Where Ythe Itufted yarn 32 isv set inthe looped or crimped condition. As `the backing material 30 leaves the setting chamber 33, the crimpedy yarn 32 is continuously raveled from the `back-ing and is wound about the .cone 34. f
'Where the yarn is to be used to produce a tufted fabric, the Yyarn may be tufted back into :the very backing material in which it was set as illustrated in Fig. 4..
tufted configurations in the tufted fabric 20 are set by any usual treatment. The pile yarn 23 is then pulled from the fabric 20 and fed to the needles of tufting machine 24, while at the same time the backing material 4of the fabric 2@ is fed beneath the tufting machine 24, so that the crimped yarn 23 is tufted back into the fabric 20. The retufted fabric 25 is then taken up on roll 26.
The present invention also includes the process shown in Fig. 6 in which a woven fabric is continuously produced from crimped yarn, A continuous loop of backing material 4.9 is fed to tufting machine 41 and setting chamber 42. The yarn 43 is tufted into the .backing material 40 and then set in the tufted condition in setting chamber 42 and is unraveled and beamed directly to the loom 44 where it becomes the warp yarns in the woven fabric 45.
An important advantage of the invention is that it accomplishes the crimping and curling of yarns in a form where they can be set or dyed and set evenly on conventional dyeing equipment and in a minimum time. Thus, as shown in Fig. 4, all of the equipment is that normally used in handling and producing piece goods. The handling of individual yarns is limited to the tufting machine which is, of course, a standard goods making machine.
Having thus described my invention, I claim:
l. A method of producing crimped yarns comprising the steps of needle-tufting textile yarns in a backing material to form a tufted pile fabric, subjecting the resulting pile fabric to setting treatment to set the loops in the tufted yarns and removing the set yarns from the backing material.
2. The textile yarn made according to the process of claim 1.
3.
