2,736,289 2/1956 Allen 118/325 X 8 Claims, 1 Drawing Figure COMPRESSED AIR Patnted June 19, 1973 COMPRESSED AIR INVENTOR. RUDOLFS KODIS A 7' TO RNE VS YARN COATING DEVICE This invention relates to a device for applying a liquid addendum to a yarn. In a specific aspect the invention relates to a new and improved device for lubricating yarns. In another aspect the invention relates to the application of a liquid treating agent to a continuous length of strand material.
Although it is known to utilize an atomizer to spray liquid addendum onto fibers, such techniques have generally been considered messy and wasteful. It is an object of the present invention to provide a new and improved device for applying liquid addendum onto a traveling continuous length of yarn. It is an object of the invention to minimize, if not eliminate, the loss of liquid addendum in a spraying operation. Another object of the invention is to provide for uniform application of liquid addendum to individual filaments of a multiple filament yarn.
Other objects, aspects and advantages of the invention will be apparent from a study of the specification, the drawing and the appended claims to the invention.
In the drawing, the single FIGURE is an elevational view in cross section of a device in accordance with the present invention.
Housing 11 forms a generally cylindrical chamber 12 through which the yarn 13 is passed by way of yarn inlet 14 and yarn outlet 15. Inlet 14 and outlet 15 can be in the form of ceramic or plastic tubes 16 and 17 extending through corks l8 and 19, respectively, positioned in openings in opposite walls of the housing 11. The inner diameter of tubes 16 and 17 is only slightly larger than the diameter of the yarn being processed, to minimize the flow or air through the tubes 16 and 17. Other forms of yarn guides can be employed as the yarn inlet and yarn outlet, for example, holes can bedrilled in the walls of the housing 11 of a size corresponding to the size of the yarn to be processed. However, the corks 18 and 19 and'tubes 16 and 17 have the advantage of being readily replaceable when it is desired to change the denier of the yarn being processed. Although not shown in the drawing, housing 11 can be formed of two parts with the dividing line being along the plane of the yam path to permit rapid stringup as well as to aid in the construction .of the device.
A reservoir 21 of liquid addendum is positioned in the lower portion of chamber 12. An aspirator nozzle 22 is positioned within chamber 12 and comprises a first tube 23 and a second tube 24. Tube 23 extends through a wall of housing 11 to a source 25 of compressed air or other suitable aspirating gas. Tube 24 extends downwardly into the reservoir 21 to supply liquid addendum to the nozzle 22. Tubes 23 and 24 can be connected by a plate or web 27 for mechanical support. Nozzle 23 is positioned below the yarn path and is directed upwardly at the yarn 13 as it passes between inlet 14 and outlet 15 to cause at least a portion of the droplets of aspirated liquid to contact the yarn. In a presently preferred embodiment of' the invention the nozzle 22 can be positioned adjacent the yarn path to cause a separation of the filaments of a multiple filament yarn to permit application of the liquid addendum to the individual filaments. A valve 26 can be operatively positioned in conduit 23 exterior to housing 11 to provide for adjustment of the rate of flow of air through the nozzle and thus the amount of liquid sprayed onto the yarn.
When elements 33-37 are in the position illustrated in the drawing, they serve as a liquid trap to recover any entrained liquid addendum in the spent aspirating air being vented from chamber 12. The trapped liquid droplets accumulate in chamber 38 as a body until the level thereof reaches the outlet opening of conduit 33, at which time the excess liquid drains downwardly through conduits 33 and 31 to the reservoir 21. Similarly those droplets of liquid addendum in the spray from nozzle 22 which do not contact the yarn either fall back into reservoir 21 or coalesce on the inside walls of housing 11 and drain back into reservoir 21. Thus the mess usually associated with sprays is eliminated andthe loss of liquid addendum is minimized.
The housing 11 can be fabricated out of any suitable material including glass, metal and plastics. However, it is presently preferred that at least a portion of the housing be transparent to permit visual observation of the level of the reservoir 21. The term liquid addendum includes any known liquid treating agent or liquid suspension of finely divided particulate material. The invention is useful for applying lubricants, sizings, conditioning agents, and finishing agents. The term yarn ineludes single or multiple continuous filament yarns and tows, staple yarns and rovings, yarns containing a blend of staple fibers and continuous filaments, and the like. The filaments can be natural fibers and/or synthetic fibers. The device of the present invention is particularly applicable to any melt spinnable synthetic organic thermoplastic polymer, for example, polyamides, polyesters, polyhydrocarbons such as polyethylene and polypropylene, polyurethanes, polyureas', vinyl polymers such as polyvinyl chloride, polyvinylidene chloride, and copolymers thereof, acrylic polymers such as polyacrylonitrile when sufficiently plasticized to render it fusible, copolymers of acrylonitrile, halogenated hydrocarbons such as polychlorotrifluoroethylene, polyacetals, polyanhydrides, polyoxymethylenes, polyformals, polyethers, polythioethers, polysulfides, polythioesters, polysulfones, polythioureas, polythioamides, polysulfonamides, polyimides, and polytriazoles. The preferred group of polyamides comprises such polymers .as poly(hexamethyleneadipamide), poly(hexamethylene sebacamide), poly(epsiloncaproamide) and the copolymers thereof. Among the polyesters that may be mentioned, besides poly(ethylene terephthalate), are the corresponding copolymers containing sebacic acid, adipic acid, isophthalic acid as well as the polyesters containing recurrent units derived from glycols with more than two carbons in the chain, e.g-., diethylene glycol, butylene glycol, decamethylene glycol and trans-bisl ,4-( hydroxymethyl)cyclohexane.
The device of the present invention can be employed for applying finishes in the spinning process just prior to the take-up winder, but is advantageously utilized between the feed packages and the processing machine, such as a knitting machine. Thus the yarn can be processed while the finish is still wet.
Reasonable variations and modifications are possible within the scope of the foregoing disclosure, the drawing and the appended claims to the invention.
