1 NON-TWISTED, HEATHER YARN AND METHOD FOR PRODUCING SAME It is desirable to produce a non-twisted yarn having a unique prominent heather for forming heather fabrics.
This invention therefore resides in a unique, nontwisted, heather yarn which is formed by controlling the impact of fluid and tension on the yarn to produce a yarn in which each of the secondary bundles in each unit length of yarn of about 6 inches has a secondary bundle portion formed of greater than about 30 percent of the filaments ofits major bundle and each of the secondary bundles in each unit length of yarn of about 8 inches is non-uniformly, differently oriented relative to the yarn axis. Each major yarn bundle has from about to about 90 percent of its filaments cohering to form secondary bundles with the remaining filament of each major bundle varying in number along the length of the yarn, being interlaced with other major bundles ofthe yarn, and being randomly oriented about the yarn axis.
Other aspects, objects, and advantages of the present invention will become apparent from a study of the disclosure, the appended claims, and the drawings.
The drawings are diagrammatic views of the process and product of this invention.
HO. 1 shows the process of the invention,
FIG. 2 shows a side view of the composite yarn of this invention that is formed by the process of FIG. 1,
FIG. 3 is a cross sectional view of a major bundle showing a secondary bundle comprising about 65 percent of the total filaments,
FIG. 4 shows a secondary bundle comprising about 90 percent of the total filaments,
FIG. 5 shows a secondary bundle comprising about 10 percent of the total filaments,
FIG. 6 shows a secondary bundle oriented at one location relative to an axis X of the yarn and I FIG. 7 shows the remaining filaments oriented at another location relative to the axis X of the yarn.
Referring to FIG. 1, a plurality of major yarn bundles 2, 4, 6 pass from their individual packages 8, l0, 12 which are mounted on a creel.
At least one of the major yarn bundles 2 or 4 or 6, preferably all of the major yarn bundles 2, 4, and 6, for example, are of substantially different colors relative one to the other. Each of the major yarn bundles, is formed of a multiplicity of non-twisted, continuous, synthetic filaments.
The major bundles 2, 4, 6 are passed through an eye let guide 16 about an in-feed draw roll 18 and about an out-feed draw roll 22 for drawing each of the major yarn bundles.
In the method of this invention, the out-feed draw roll 22 is maintained at a peripheral speed in the range of about 500 to about 2,000 meters per minute. The preferred speed is dependent upon the type of material being utilized and particularly the size and number of filaments. Once these variables have been determined, the particular optimum speed within the above speed range can easily be determined. It has been determined however that at speeds higher or lower than the above range, the hereafter more fully described yarn entanglement will be of reduced quality and quantity.
From the out-feed draw roll 22, the bundles 2, 4, 6 are brought into contact one with the other by a converging roller 23 for forming a composite yarn 24.
The composite yarn 24 can hereafter be passed through apparatus for texturizing or crimping the yarn at an elevated temperature in a zone of turbulence, for example by passing the yarn through a fluid jet 26 into a chamber having a plurality of stacked members such as balls or rods as shown in the art and hereafter passed through a quench tube 28 at which location the yarn is cooled in a wad setting the crimp.
The composite yarn 24 discharging from the quench tube 28 thereafter is associated with apparatus for placing said composite yarn 24 under a tension in the range of about 0.03 to about 0.20 grams per denier for substantially straightening the fibers prior. to entanglement.
The yarn can be placed in tension by a tension gate 30-idler roll 32-roll 34 assembly as shown in FIG. 1 and as known in the art. Other means as known in the art can be utilized.
The composite yarn is passed through an entangler 36 and thereafter is wound together forming a yarn package 38 with the yarn tension between roll 34 and package 38 being in a range of 0.008 to 0.03 grams per denier.
The entangler 36 has a plurality of gas or fluid jets which are connected to a pressurized gas source such as an air supply source for example. The entangler 36 has an opening for the passage of the composite yarn therethrough with the jets opening into a passageway of the entangler at spaced locations for impacting the yarn 24 with gas streams from a plurality of jets spaced a substantially equal arcuate distance one from the other about the axis of the yarn 24 and directed generally toward said axis. The yarn 24 is impacted by gas streams fed at about 40-150 psig while under a tension maintained in the range of about 0.008 to 0.03 grams per denier and while passing through the entangler 36 at a speed maintained in the range of about 62 percent to about percent of the speed of the yarn at the locationof the out-feed draw roll 22.
At feed pressures of less than 40 psig on the gas streams impacting the yarn the amount of entanglement will be insufficient and the percentage of filaments forming the secondary bundles will be greater than percent thereby forming other than the unique heather yarn of this invention. At pressures greater than about psi the amount of entanglement will be greater than desired and the percentage of filaments forming the secondary bundles will be less than 10 percent and there will not be intermittent portions where the secondary bundles are formed of greater than 30 percent over each 6 inches unit length thereby forming other than the unique heather yarn of this invention. Further, at tensions greater than about 0.03 grams per denier the amount of entanglement will be less than desirable, the major bundle will be formed with greater than 90 percent of the filaments of that bundle, the secondary bundles within a unit length of about 8 inches may not be differently oriented and the yarn will be different than the unique heather effect yarn of this invention. At tensions less than about 0.008 grams per denier, there will be an excessive amount of entanglement, the major bundle will be formed of less than 10 percent of the filaments of that bundle thereby producing a blended yarn as opposed to the unique heather yarn of this invention.
In order to accentuate the heather effect of this invention, the filaments of at least one, preferably all of the major bundles are of a trilobal cross-sectional configuration. These differences cause the unique heather Y yarn to be bold and of sparkling sheen which is of exabout 90 percent'of its filaments cohering to form a secondary bundle 42 (better seen in FIGS. 3-7) with the remaining filaments 44 of the major bundles varying in number along the length of the yarn 24, being interlaced with the other major bundles forming the yarn and being randomly located about the yarn axis X. The interlacing of the remaining filaments 44 can be with the secondary bundle or remaining filaments or both of one or more other major bundles.
In each unit length of the yarn 24 of about 6 inches, each of the secondary bundles has a portion thereof formed of greater than about 30 percent ofthe filaments of its major bundle. Further, in each unit length of the yarn 24 of about 8 inches, each of the secondary bundles are differently oriented relative to the yarn axis. This unique movement about the axis and Other modifications and alterations of this invention will become apparent to those skilled in the art from the foregoing discussion and accompanying drawing, and it should be understood that this invention is not to be unduly limited thereto.
