Definitions

  • the present invention relates generally to the treatment of yarn in package form.
  • Space dyeing has also been accomplished through the use of resists which alter dye sites in the yarn to cause them to be unreceptive to certain kinds of dyes. See, for example, U.S. Patent No. 3,743,477 which discloses certain fiber-reactive compounds which may be applied to specified fibers to provide local reservation against dyeing with anionic or acid dyes. See also the application of resists by roller printing to form a pattern of resist and non-resist sections as disclosed in U.S. Patent No. 3,700,402. However, roller printing fine denier yarns is both impractical and commercially unattractive because of the high cost.
  • the present invention is predicated, in part, on the discovery that a yarn treating agent can be selectively and reproducibly diffused into a mass of yarn in package form by first compressing the package axially to a predetermined density, introducing a prescribed (metered) quantity of the yarn treating agent into the compressed package and then diffusing the yarn treating agent into the package by means of a diffusing fluid under pressure.
  • the diffusing fluid under pressure causes the yarn treating agent to selectively penetrate the package and to coat the individual strands of yarn or fibers and, if desired, to fully penetrate the package.
  • the quantity of yarn treating agent introduced is optimally only that amount which is retained within the package.
  • the method and apparatus of the present invention involves taking a yarn package having a predetermined initial density in respect of the individual strands of yarn in relation to each other, compressing the yarn package to a predetermined second density, infusing a prescribed quantity of yarn treating agent, e.g., a dye acceptance modifier, a dye, or the like, into at least one end of a yarn package, and applying a diffusing fluid to at least one end of the compressed yarn package which was infused with the treating fluid to diffuse the treating fluid through the compressed yarn package.
  • the diffusing fluid (which may be air) passes through the compressed yarn package and carries with it the yarn treating agent. In this manner, controlled penetration of the yarn treating agent is obtained.
  • the process can also include the step of infusion of the yarn package with a heated fluid, such as steam, following the diffusion step to cause reaction between the yarn treating agent and the yarn.
  • the result of these process steps can provide a yarn package having different sections which contain varying amounts of dye.
  • the section contiguous to the end at which the dye was infused there is a relatively large concentration of dye.
  • the section contiguous to the opposite end of the yarn package there is little or virtually no dye present.
  • the middle section there is a concentration or proportion of dye which is intermediate that of the two end sections.
  • a yarn package may be treated with one or more dyes thereby producing yarn which has contiguous sections of differently colored lengths. For example, if a first dye is introduced at one end of the package, and a different color dye is introduced at the other end of the package, yarn having lengths of the two colors in addition to a blend of the two colors will be produced. Moreover, by a manner discussed in detail hereinbelow, it is possible to introduce two or more dyes at each end of the package thereby providing a dyed yarn which has contiguous lengths of at least four colors and additional lengths of blends of the colors or dyes used. It is also possible to eliminate the blending of the colors to produce contiguous lengths of a plurality of different colors. When desired, a totally random pattern of colored lengths of yarn can be produced. Therefore, the present invention provides complete control over the color effects of the end product through the use of a single process.
  • end of a package of yarn is intended to denote a face of the yarn package which is perpendicular to the longitudinal axis of the wound yarn.
  • a yarn package has two ends and a circumferential surface, the latter being cylindrical or conical in shape, for example, depending upon the method of winding employed.
  • the term “yarn in package form” or “yarn package” is intended to denote and mean a mass of yarn which has been wound on a core such as a tube, cone, pern, dye-spring, or other such conventional holders and would include also such yarn packages from which the core has been removed.
  • fiber and “yarn” have the same meaning as those normally used in the art, i.e., “fiber” means an individual filament of natural or synthetic material and the term “yarn” means a bundle of several fibers gathered together and normally twisted together.
  • An inherent advantage of the present invention is that it makes possible the rapid treatment of a large mass of yarn in compact form, i.e., in the form of a package of yarn rather than in skein, warp, or knitted sock form.
  • a typical yarn package may be dyed in one minute or less, whereas prior art techniques may require an hour or more.
  • the particular type of package employed in the present invention is not critical.
  • the yarn may be wound on a cone, tube,or pern, or wound to form a package in any similar manner.
  • the repeat pattern of the treated yarn will vary in accordance with the method used to wind the yarn.
  • the yarn is wound with constant speed and constant traverse, i.e., drum wound, and the package is treated from the ends, the repeat sections of the yarn which are fully treated, partially treated and untreated will be of the same proportional lengths throughout the entire mass of yarn in the package. This gives the most desirable effect and distribution of dyestuffs.
  • a package of yarn is obtained in accordance with the present invention which has the characteristics of a space dyed yarn package.
  • Direct dyeing of the package using another embodiment of the method in which one or more dyes are infused into different surfaces also offers many advantages. Color effects not otherwise obtainable are accomplished in a simple manner with maximum utilization of dye and minimum expenditure of energy.
  • the method of the present invention is reproducible in the sense that if the same amount of yarn treating agent is used followed by a uniform, nonvarying, treatment of compression, infusion and diffusion with a fluid under pressure, the repeat sequences are substantially the same. Where more than one dye is used in accordance with the present invention, then the repeat sequences of the colors in the yarn package are also reproducible.
  • yarn in package form may be treated with other agents such as yarn lubricants, soil retarding agents, flame retarding agents, fungacides and the like in order to create certain desired effects.
  • the method of the present invention is useful in permeating a yarn package with any conventional or known yarn treating agent in a predetermined manner.
  • Another advantage of the present invention is the ability to treat a yarn package without the application of heat. Apart from the saving of energy, the treatment without heat permits uniform distribution of the treating agent throughout the yarn package resulting in, for example, uniform dyeing of the yarn package. It also permits dyeing of fibers which are undesirably effected by heat, such as nylon, rayon, wool, and cotton, without the undesirable effects.
  • Another object of the present invention is to provide a method of treating yarn which does not require the application of heat in any form, thereby making the method more energy efficient.
  • a further object of the present invention is to provide a method for treating yarn which is subject to shrinkage or modification by heat such that said yarn can be treated without shrinkage or modification.
  • Apparatus 10 includes yarn package receiving and dyeing means 11 which includes an upper vertically movable header 12 and a stationary lower header 13. Headers 12 and 13 are essentially identical and corresponding parts have therefore been given the same reference numerals. Accordingly, each header consists of a circular end plate 14 and a cylindrical side wall 16 which is joined thereto by welding or other appropriate means. The opposite ends of side wall 16 are attached to a curved foraminous plate 17 which defines therein a plurality of foramina 17a.
  • Each plate 17 is connected to an axially aligned cylindrical member 18 which is joined to the foraminous plate 17 and to the circular end plate 14.
  • a yarn agent conduit 21 communicates with the interior of chamber 19 and a second conduit 22 communicates with chamber 20.
  • assemblies 24 Extending from the inner facing ends of side walls 16 of the respective headers 12 and 13 are assemblies 24, each of which includes an inflatable skirt 26 surrounding an inner rigid core member 27.
  • the skirt 26 is wrapped around the core member 27 and the ends of the skirt abut at 28.
  • Two circular clamps 29 and 30 seal the ends of the skirt 26 against the outer periphery of the core 27.
  • Each assembly 24 is attached to its respective header 12, 13 by a series of peripherally positioned brackets 31, one end 31a being wedged in a circumferential recess 27a in the core member 27, and the other end 31b being held tightly against the surface 23 of headers 12 and 13 by bolts 32.
  • the core member 27 is provided with a radial passage 27a which is connected by fitting 27b to hose 33 which is in turn connected to the manifold 34 (Fig. 1) and air pump 36.
  • Circular plate 14 of header 12 is threadably connected to a rod 37 which is the actuating rod of air actuator 38.
  • the latter is mounted upon frame member 39 and contains a piston (not shown) which may be reciprocally moved in opposite directions by the admission of air through valve 40 in lines 41, 42 into opposite ends of the actuator. Accordingly, air admitted by valve 40 through line 41 to the upper end of actuator 38 will drive the header 12 downwardly toward fixed header 13.
  • the apparatus of the present invention includes means for metering yarn treating agents such as dyes into the headers 12 and 13 and means for subsequently directing air into the headers to cause diffusion of the yarn treating agent into a yarn package as will be more specifically described.
  • yarn treating agents such as dyes into the headers 12 and 13
  • means for subsequently directing air into the headers to cause diffusion of the yarn treating agent into a yarn package as will be more specifically described.
  • Two identical separate systems for metering a yarn treating agent and for air diffusion have been shown in Fig. 1, and for simplicity, the various parts thereof will be given the same reference numerals.
  • Each metering system includes a motor 45 which drives a metering pump 46 whose input conduit 47 admits yarn treating agent (e.g. dye) to the pump.
  • the outlet of pump 46 is connected to conduit 48 which includes a check valve 49 permitting flow only in the direction of the arrow.
  • Conduit 48 carries dye to conduit 21 which supplies chamber 19 in the lower header 13. Air under pressure may be admitted to conduit 50 and may not proceed farther if the valves 51 are set to check the flow of air respectively in conduits 52 and 53. Valves 51 are operated by solenoids 54 which are under the control of timer 56. When valves 51 are opened, check valves 57 permit the flow of air through conduit 58, and since check valves 49 will block the flow of air toward pump 46, air may only flow through conduits 48 and 60, into conduits 21 respectively, and into chambers 19 in upper and lower headers 12 and 13. It will be understood that identical systems (not shown) will admit dye and air into conduits 22 and thus into chambers 20 in headers 12 and 13.
  • headers 12 and 13 define therebetween a yarn treating chamber 62 in which a cylindrical yarn package 63 may be placed.
  • Fig. 2 illustrates the chamber in its open (yarn package receiving/discharging) position and Fig. 3 in the closed (yarn package treating) position.
  • the yarn package 63 consists of many turnings of yarn helically wound on a spool 64, the lower end 64a which will initially be placed within a chamber 18a defined by lower cylindrical member 18.
  • An axial drain 65 connects the interior of chamber 18a and the exterior of header 13.
  • Fig. 3 illustrates the position of the headers 12 and 13 when the upper header 12 has been thrust downwardly by the actuator 38.
  • the yarn package 63 has been axially compressed to approximately 50% of its initial length and that the members 18 (upper and lower) provide means for the core 64 to be accommodated during such compression.
  • the degree or amount of compression of a yarn package is related to its initial density. If a package is very dense, less compression will subsequently be required to obtain satisfactory diffusion of the yarn treating agent.
  • Fig. 3 illustrates that when the yarn package 63 has been compressed, air will be admitted from pump 36 through lines 33 and into the inflatable skirts 26, which when they are inflated exert a radial sealing force against the sides of the package 63.
  • the purpose of the inflatable skirt 26 is to seal in the yarn treating agent or dye as it is diffused throughout the package, and the skirt has the capacity to accommodate different diameters of package while achieving this effect.
  • the curved foraminous plate 17 actually causes the axial compression of the package, the plates being concave to match the convex end contours of the yarn package. Therefore, all axial forces will be essentially evenly distributed throughout the radial cross section of the yarn package. This will promote greater uniformity in diffusion of the yarn treating agent or dye throughout the package.
  • the core 64 can be perforated to permit egress of diffusing fluid through the core and therefrom through drain 65.
  • the yarn package 63 should have a known initial (uncompressed) density upon the core. It is important that yarn packages of a given production run have a fairly uniform density so that the same axial compression can be used for all such yarn packages of a production run. In order to achieve such uniformity it may be necessary to rewind the yarn packages to a predetermined initial density.
  • a typical yarn package used in the machine of the invention for example, weighs 2 1/2 pounds (1135 grams) and is wound on a perforated plastic tube 1 13/16 inches (4.6 centimeters) in diameter and 6 3/4 inches (77.1 centimeters) long.
  • the yarn package measures 7 3/4 inches (19.7 centimeters) in diameter by 5 1/4 inches (13.3 centimeters) long at the perimeter and 5 3/4 inches (14.6 centimeters) long at the core. Its shape is that of a cylinder with conical ends. Volume is about 240 cubic inches (3931 centimeters).
  • yarn package density is about 0.0104 pounds per cubic inch (0.288 grams per cc).
  • the package is compressed, prior to treating, between the heads of the machine to about 71.5% of its original height (measured at the outside of the package). This causes the yarn package density to increase about 40% to about 0.0146 pounds per cubic inch (0.404 grams per cc). This higher density improves wicking of the yarn treating within the yarn volume without seriously impeding flow of that agent from the metering pump through the foraminous plate or plates into the yarn package.
  • timer 56 controls the sequence of operation of the system which may be initiated by depressing start button 68.
  • a yarn package 63 of prescribed initial density will be placed into open chamber 62.
  • Timer 56 will initiate actuator 38 to move header 12 downwardly to the position of Fig. 3 and in so doing, the yarn package will be compressed axially to a second prescribed density.
  • Skirt 26 will then be inflated.
  • Metering pumps 46 will next cause a measured quantity of yarn treating agent such as a dye to flow into the respective sets of chambers 18 and 19.
  • the amount of such agent is metered and where total dyeing of a yarn package is contemplated, the amount metered should be equal to or only slightly greater than the amount which is to be retained in the package. Excess amount, if any, will flow from chamber 62 through drain 65. It has been found that where selected portions of a package are to remain untreated, such portions should be diffused (using the method and apparatus of the invention) with a neutral fluid, for example, water which acts to prevent the diffusion of the yarn treating agent into the portions selected for non-treatment.
  • a neutral fluid for example, water which acts to prevent the diffusion of the yarn treating agent into the portions selected for non-treatment.
  • the timer 56 will initiate appropriate closure of valves 51 and opening of valves 54 to admit a diffusing fluid (air) into the chamber 18, 19 and into the yarn package.
  • the diffusing fluid will carry the yarn treating agent throughout the yarn package, and the air, which is initially trapped in the package will be displaced as the yarn treating agent is propagated into the sections to be treated.
  • Such displaced air and air or other fluid which is used to diffuse may flow from the chamber 62 between the abutting ends of skirts 26, and where the core 64 is perforated, through the center of the core and through drain 65.
  • the foregoing process takes about one minute, which is considerably shorter than the amount of time required for prior package yarn dyeing methods which may take one hour or more. Furthermore, optimally only the amount of yarn treating agent or dye is introduced into the package which the yarn package is capable of retaining. In some instances, in order to assure complete coverage throughout the package a slightly greater amount of yarn treating agent may be used, but in any case, the amount required is much less than used in prior yarn package systems and greatly reduces pollution and energy problems.
  • the excess treating (dyeing) agent introduced into the package not only assists in assuring that sufficient treating agent is present for complete dyeing of the yarn package but also the excess amount introduced tends to aid the efficiency of the process.
  • the diffusing fluid (air) has been released into the package, the propagation of the dye due to the diffusing action of the air and the wicking (capillary) action of the package will be very rapid.
  • the diffusing air will "blow out" the excess dye and the amount of the excess may be usefully measured and retained for further use in subsequent dyeing.
  • the excess dye which is collected after the diffusing air has driven such excess from the package also contains an exactly known combination of different dyes (if the yarn package has been space dyed) or of a solid color dye. In any case the excess can subsequently be used in a further dyeing process by itself or in combination with other dyes because its composition is precisely and mathematically known.
  • Another advantage attendant upon the collection and measurement of the excess dye received from the yarn package is that the amount collected directly may be related to the amount retained. In other words, if with respect to a particular yarn package or packages, the excess received from them is significantly greater than say 20%, if this is the predetermined amount of the excess, then the operator of equipment will know immediately that there are voids or undyed areas in the package. This may be caused by a lack of uniformity in the initial density of the package after it is wound or in a variance in the degree of compression of the package to a prescribed density.
