7 c. s. HAWKINS 3,237,269
YARN BULKING JET Filed Sept. 26, 1963 INVENTGR C. SPENCER HAWKINS ATTORNEY United States Patent 3,237,269 YARN BULKING JET Charles Spencer Hawkins, New Castle, Del., assignor to E. I. du Pont de Nemours and Company, Wilmington. Del., a corporation of Delaware Filed Sept. 26, 1963, Ser. No. 311,839 6 Claims. (Cl. 28-1) This invention relates to the treatment of moving threadlines and especially apparatus for the continuous fluid treatment of filamentary yarn.
In the processing of synthetic fibers, most often produced as continuous filaments, various treatments have been devised to produce continuous yarns with different properties according to the desired effect or requirements of their use. Recent developments in the textile industry have provided useful routes to obtain these effects by treatment of running y-arns with fluid streams. The fluid processes permit eflicient treatment at high linear yarn speeds and, in turn, reduce processing costs. These processes require apparatus which bring the yarn into proper contact with a fluid stream to produce the desired result.
Breen U.S. 2,783,609, for example, has disclosed a product made by a new technique for improving the bulk of continuous filament yarns, rendering them light in weight and causing them to have the bulk and surface texture of yarns spun from staple fibers. This technique involves exposing a fiilamentary material to a rapidly moving turbulent fluid, thereby inducing a multitude of crunodal filament loops at random intervals along the individual filaments. The treating jets disclosed by Breen and others have required that the threadline be broken and a free end of yarn be laced through the yarn passage to commence the treating process. Breen and Sussman U.S. 3,009,309 reveals the use of fluid twister apparatus to impart a high speed twisting motion to a filament, yarn or strand by means of torque applied by a high velocity fluid stream. Bunting and Nelson U.S. 2,985,995 reveals a yarn which has a cohesive structure as a result of interweaving and interlacing of the individual filaments by means of fluid vortices. These patents disclose jets with openings to admit the yarn to be treated but no provision is made in such jets to confine the running threadline within the fluid stream. In the guiding of running threadlines, pigtail guides are commonly used for ease of string-up on-the-run. These devices require a slackness to accomplish the string-up. Smith et al. U.S. 2,5 88,- 053 contains an example of a thread-guide which is readily laced in which the threadline is temporarily aligned in a fixed eye and which automatically releases when the threadline is sufficiently tensioned.-
This invention provides a closure means for yam-treating jet devices. The structure is extremely simple and rugged, employing comm-on materials of construction. It is readily opened to admit a running threadline without interruption and, when released, is self-closing. In the closed position, the running threadline is positively confined. Moving mechanical linkages are unnecessary in the assembly of the preferred embodiment. This invention may also be adapted for use as a guide for running threadline, a defect detector and the like.
In accordance with the present invention a readily loadable yarn guide device is provided comprising a body member having at least one essentially flat surface, a cover lying against the said surface and flexibly retained at one edge against said surface, an essentially straight line channel for yarn passage between the said surface and the said cover, at least one of the said cover and body member terminating :on the side of the said channel opposite to that at which the said cover is retained 3,237,269 Patented Mar. 1, 1966 in a lip tapering toward the junction between the said cover and the said body.
The invention will be more readily understood by reference to the drawings.
FIGURE 1 is a top view of a device of the present invention in one of its simplest forms.
FIGURE 2 is a top view of a device of the present invention adapted for use in fluid treatment of a running thread line to produce the comp-act interlaced yarn of Bunting and Nelson U.S. 2,985,995.
FIGURE 3 is a cross-sectional elevation On line 3-3 of FIGURE 2.
'FIGURE 4 is a view in perspective of an alternative embodiment of the device of the present invention.
Referring particularly to FIGURE 1, the device comprises a body 1 having a cover 2 flexibly retained at one edge against the fiat surface of the said body. In the simple embodiment shown, cover 2 is flexibly retained against body 1 by flexible web 3 and bolt 4, the width of opening possible upon flexing being controlled by the stop member 5. From the drawing it will be apparent that cover 2 may be flexed away from body 1, thereby providing an opening between them. An essentially straight line channel 6 for yarn passage is provided between the surface of body 1 and cover 2. A lip 7 on body 1 and lip 8 on cover 2 provide a string-up passage tapering toward the mating surfaces of 1 and 2. Mounting bracket 9 containing screw retaining holes 10 may conveniently be provided to permit mounting on machinery framework not shown.
A more sophisticated embodiment is shown in FIG- URE 2. In this embodiment provision is made for fluid treatment of a running thread line to produce the compact interlaced yarn of Bunting and Nelson U.S. 2,985,- 995, the fluid being introduced to the yarn running through channel 6 by means of fluid passage 11. The device is shown as several parts viz. body member 1 (through which fluid passage 11 passes), cover 2 and a bracket 12, all rigidly retained in cantilevered tension by bolt 4. In this embodiment channel 6 is provided by a slot along cover 2. Thin web 3, a portion of cover 2, provides flexibility of the cover when a force is applied to separate body 1 and cover 2. Bracket 12 provides means for mounting a stop screw '13 which regulates the distance which cover 2 may be flexibly moved from body '1. (Bracket 12 also may provide tension means such 'as spring 14 to control the force required to separate cover 2 from body 1.)
FIGURE 3 is a cross-sectional elevation through lines 33 of FIGURE 2 and shows thread line 15 in channel 6 and the relative position of fluid passage 11.
In the embodiment illustrated in FIGURE 4, body 1, which is shaped to provide yarn channel 6 and lip 7, is held against cover 2 by flexible clamp 16 which flexes at groove 17. The clamp is secured to the body by set screws 18 and similarly to the cover by set screws not shown. Cover 2 is provided with handle '19 to assist opening during loading and unloading operations. Modification for fluid treatment of this embodiment can be made by providing -a passage for fluid similar to fluid passage 11 of FIGURE 2.
In operation the continuous strand of yarn is placed against the string-up throat provided by lips 7 and 8. Cover 2 is then pressed back to permit the yarn to reach channel 6 in which it is intended to run. Cover 2 thereupon cl'oses upon body 1 to retain the yarn in the channel. A mechanical device such as a cam or lever action may be employed to open and close cover 2.
As shown in the figures the parts of this apparatus are conveniently of simple rectangular shapes with flat mating surfaces which can be machined easily by conventional methods. Other forms and shapes may be produced by forging or casting without departing from the spirit of the invention. The mating surfaces which form the enclosure for the yarn channel may be curved as well as planar. The yarn channel may be more complex than the simple grooved passage shown to produce the desired yarn treatment. Thus yarn channel 6 and the mating faces may be inclined as well as perpendicular to the external body faces. While the fluid passage 11 is shown to intercept yarn channel 6 perpendicularly in the figures, in actual practice, any desired angle may be used. In Hallden US. 3,084,413, for example, the fluid conduit is skewed with respect to the yarn passage. In other words, the apparatus may take many geometric forms but only the simplest and, therefore, generally preferred embodiment of the invention is depicted in the drawings.
The apparatus of this invention may be fabricated from readily available materials of construction, such as metals or plastics. The principal requirement of the cover is that it be sufliciently elastic or flexible to be deflected without being deformed. The conditions of use will generally dictate the other property requirements. Yarn treatment at elevated temperatures will usually require a dimensionally stable metal. Corrosion-resistant materials may be needed when steam or chemically reactive gases or liquids are used in the treatment. A combination of materials may be employed. T o withstand abrasion by the running threadline, for example, a wear-resistant ceramic, corundum or metal alloy insert may be fitted in the yarn passage in a cover plate of spring steel.
For satisfactory lacing, a surprisingly narrow gap will accommodate a continuous multifilament yarn. For example, a strand of 840-denier 140-filament nylon yarn will pass through a slot approximately .002 to .003 inch wide. The yarn bundle appears to spread into a ribbon of filaments momentarily as they slip through the passage and regroup in the treating channel.
The space required to admit the yarn bundle determines the amount of deflection required of the cover. Knowing this, the cross-sectional dimensions of the flexing portion of the cover can be calculated from standard stress formulae for cantilever beams.
Using these formulae, a cover plate as shown in FIG. 2 of a steel with maximum allowable bending stress of 80,000 p.s.i. and a modulus of elasticity 30,000,000 psi. having a flexing section of thickness .062 inch, width .281 inch and force arm 2.37 inches. The maximum allowable deflection of the cover plate is .164 inch requiring a force of 13.5 lbs. The stop plate is then positioned so that the deflection of the cover will not exceed the allowable maximum. Other dimensions may be selected to provide the desired string-up passage and force required to open the string-up passage.
The apparatus of this invention may be used for various fluid processes under diflerent conditions. The treating fluid may be gaseous or liquid. A gas such as air may be used to bulk, interlace or otherwise modify a multifilament yarn. The gas may be heated to plasticize the yarn. A fluid such as water, size solution, solvent or other liquid may be applied to a running yarn to achieve a desired result.
The device may be further modified to treat a plurality of running threadlines simultaneously by providing a series of parallel yarn channels. In this case, separate fluid passages are provided to accommodate each threadline with appropriate fluid. The shape of channel 6 is not critical. It may be round, half-round, or rectangular in cross section. It may be formed by a groove in body member 1, a groove in cover 2 or mating grooves in each of these members.
This invention also comprehends use of this device for purposes other than fluid treatment. Without fluid conduits, the apparatus may be used as a thread guide for single or multiple threadlines. The device may also be used to clean fluflFballs or slubs from a running threadline by selection of the proper dimensions for the yarn passage.
Many equivalent modifications will be apparent to those skilled in the art from a reading of the above without a departure from the inventive concept.
