Definitions

  • the invention relates to packaging of yarn for use by the consumer. More particularly, the invention relates to the treatment of a sheet of individual ends of yarn which have been dyed and wound onto a beam. The sheet of ends of yarn is 10 unwound from the beam, with subsequent separation and packaging of each end of yarn into a form suitable for knitting and/or weaving.
  • packaging dyed yarn There are several methods of packaging dyed yarn. Generally, the choice of packaging method depends ov. the yarn was dyed, and on the intended end use of the yarn.
  • Package dyed yarn is prepared by winding undyed yarn into a cone form, and causing dye to penetrate the yarn under pressure. While this process may be used for dyeing yarn with reactive dyes, vat dyes, and direct dyes, it is
  • Package dyed yarn has the advantage that cone- form yarn packages may be used for to make either woven fabrics or knitted fabrics. However, yarn which is dyed in this fashion is susceptible to undesirable shrinkage or weight loss .
  • Rope dyeing may be used for Indigo, sulfur and vat dyes, but not for reactive or direct dyes.
  • Yarn is dyed in the form of a rope having many individual threads by passing the rope through from 2 to 7 dye-baths, and then oxidizing the dyed rope in air.
  • a rope having about 320 threads is commonly used. The individual threads in the rope are separated and wound onto a beam. The threads on the beam may then be used for weaving.
  • the rope dyed threads on the beam may be transferred to cones for knitting. This is done by separating the threads on the beam into several groups of threads, and winding each group of threads onto a spool. For example, 8 spools having 40 threads each may be made from a beam carrying 320 threads. The threads on each spool are then unwound, and separated into individual threads. Each individual thread is wound onto a bobbin. The thread on a given bobbin may then be transferred to a cone. This is a time-consuming process, and the multiple transfer steps increase the possibility of thread breakage. The possibility of thread breakage also increases as the threads become finer, or as the number of threads transferred at one time increases.
  • the slasher process is another method for dyeing yarn. It may be used with Indigo, sulfur, vat, reactive and direct dyes.
  • a sheet or web of substantially parallel and non-entangled warp yarns is passed through several dye baths in sheet form, washed, dried, and wound onto a beam.
  • the sheet of warp yarns can be passed through 2 or 3 dye baths, and is then dried on hot cylinders for thermo-fixation at a temperature of 140-150° C for about a minute prior to washing. After washing, the sheet of warp yarns is wound onto a beam.
  • the sheet of yarn passes through several dye baths. The sheet is then oxidized chemically or by passing the sheet through air, and wound onto a beam after washing and drying.
  • the slasher process can also be used to dye yarn in sheet form with sulfur dyes or direct dyes. With the slasher process, different colors can be dyed simultaneously, as different groups of threads can be dyed in different dyebaths and then brought together on a single beam after drying. In package dyeing, only one color can be dyed at a time.
  • the slasher process of dyeing yarn has major advantages over the cone dyeing process. Slasher dyeing of a sheet of yarn is a continuous process, whereas cone dyeing is a batch process. Also, with the slasher process, the color of the yarn can be observed during the dyeing process, allowing color corrections to be carried out immediately. With cone dyeing, the color of the yarn is not seen until the dyeing process is complete, making color correction difficult at best. Also, the slasher process is cheaper than the cone dyeing process, as smaller amounts of chemicals are used in dyeing the same weight of yarn. Also, cone dyeing calls for greater inputs of water and energy. However, the slasher process as currently used has a significant disadvantage over cone dyeing and rope dyeing.
  • a sheet of warp yarns wound onto a beam after being dyed by the slasher process may not be conveniently used for knitting.
  • an effective method of transferring yarn dyed by the slasher process from the beam to cones for use in knitting or as filling yarns in weaving has not been developed.
  • a process of winding yarn from a beam into loosely wound hanks is accomplished by a process of winding yarn from a beam into loosely wound hanks.
  • a sheet of substantially parallel warp yarns is dyed by the slasher process using a direct dye, an Indigo dye, a reactive dye, a vat dye, or a sulfur dye and wound onto a beam.
  • Each of the individual warp yarns making up the sheet wound onto the beam is a single end of yarn.
  • At least one such beam is then loaded onto a first rotatable beam stand or drive.
  • the end of the sheet of warp yarns is then unwound from the beam and guided through a nip between two interacting rolls. After the sheet passes through the nip, the parallel ends of yarn in the sheet are separated from each other. Each of the separated ends of yarn is then individually guided to an elongated rotatable reel on a hank reeling machine.
  • Each of the ends of yarn is then wound onto the rotatable reel by simultaneously rotating the beam to release the sheet of warp yarns wound thereon; rotating the interacting rolls at a speed effective to draw the sheet of warp yarns through the nip without exerting excessive tension on the sheet; and rotating the reel at a speed effective to wind each separated end of yarn onto the reel without exerting excessive tension on the separated warp yarns.
  • Each separated end of yarn winds onto the reel in the form of a loosely wound hank.
  • the tension on the sheet leaving the beam and the tension on the warp yarns leaving the interacting rolls are monitored.
  • the rotational velocity of the beam and the rotational velocity of the interacting rolls are each controlled by a compensator rolls and regulator and may be adjusted if the tension on the sheet or the tension on the warp yarns changes. Also, by monitoring tension, the speed at which yarns are wound into hanks may be increased in a controlled manner without increasing tension on the yarns.
  • the process of the invention allows individual yarns to be transferred directly from a beam to an individual package. Also, by controlling the tension on the yarn and the hank winding speed during this process, the risk of yarn breakage is greatly reduced.
  • the invention also encompasses the apparatus for transferring yarn from a beam to individual hanks.

  • a beam 1 carries a sheet of substantially parallel warp yarns wound thereon. As shown in Figs. 1, 2, 3, 4 and 7 this beam is mounted on an axle 2 rotatably mounted on support 9.
  • the beam may carry a sheet formed from any number of warp yarns, preferably 80 to 2000 warp yarns, which have been dyed in sheet form by the slasher process.
  • a smaller beam, carrying a smaller sheet of yarn dyed by the slasher process may be positioned on the beam stand or drive if desired.
  • the beam is driven or rotated by a belt 4 attached to motor 5a.
  • the sheet of warp yarn 6 is unwound from the beam and the sheet is looped around the compensator roll 7.
  • the sheet then passes through the nip between two interacting rolls 8 which rotate in recipricol manner, driven by motor 5b.
  • the function of the compensator roll 7 is to regulate the speed at which the warp yarns are to be released.
  • the compensator roll is rotatably mounted on supports 10, which are pivotably mounted to support 9 by means of pivot pin 10a.
  • pivot pin 10a rotates.
  • This rotation causes a chain pulley attached to pin 10a to rotate.
  • a chain 10b attached to the chain pulley on pin 10a and to a second chain pulley on regulator 21 response to rotation of pin 10a by rotating the second chain pulley. Rotation of this second chain pulley controls the speed of DC motor 5a.
  • the sheet of warp yarns then enters the nip between rotating rolls 8 (Figs. 2, 5 and 6) . It then passes over a guide roll 12 mounted on support 13. Sheet 6 then passes downwards to the second compensator roll 14, and then upwards to a second guide roll 16.
  • Roll 14 is rotatably mounted on supports 15, which are pivotably mounted to support 13 by means of pivot shaft 10a.
  • the compensator roll is moved upward by the sheet of yarn, shaft 15a, and a chain pulley attached thereto, start to rotate. This causes a chain running between the pulley on shaft 15a and a chain pulley attached to regulator 20 to move, causing the pulley on regulator 20 to rotate. Rotation of the pulley on regulator 20 controls the speed of DC motor 5b.
  • AC variable speed motors as motors 5a and 5b.
  • the substantially parallel warp yarns 6a making up sheet 6 are separated into individual ends of yarn. Separation of the yarns is very easy, as the yarns are already in sheet form.
  • Each end of yarn is passed to an elongated reel 17 on a hank reeling machine. Preferably, each end of yarn goes to a different point along the length of the reel.
  • Reel 17 is rotatably mounted on support 18, and is driven by a motor 5c.
  • reel 17 can conveniently accommodate up to approximately 80 to 160 yarns 6a, although larger reels which can hold more yarns may be used. If more than 160 yarns are present in sheet 6, a plurality of hank reels can be added on the same machine to gather yarns 6a simultaneously. In the following discussion, use of a single hank reeling machine will be assumed, unless otherwise noted.
  • the process of transferring individual threads from the beam to individual hanks begins by rotating reel 17 at low speed. This causes reel 17 to begin gathering threads 6a into hanks 19. Since each yarn 6a goes to a different point along the length of the reel, each yarn is individually wound into hank form.
  • the tension on sheet 6 may be continuously monitored as it passes around compensator roll 14. If the tension on the sheet rises as it loops around roll 14, regulator 20 responds by increasing the speed at which reciprocating rolls 8 draw sheet 6 through the nip. This decreases the tension on the sheet as it passes from rolls 8 to reel 17.
  • regulator 20 responds by increasing the speed at which reciprocating rolls 8 draw sheet 6 through the nip. This decreases the tension on the sheet as it passes from rolls 8 to reel 17.
  • This has a major advantage.
  • sheet 6 tends to travel at a uniform rate, without sudden stops or starts. This greatly reduces the likelihood that threads will break as they pass to the reel. This is an improvement over the prior art process of transferring rope-dyed yarn from a beam to bobbins in multiple stages, which tends to cause excessive thread breakage.
  • regulator 20 increases the rate at which rolls 8 draw sheet 6 through the nip, increasing the tension on the sheet as it passes roll 14. This prevents tangling of threads 6a due to formation of excessive slack in the sheet.
  • the tension on the sheet is maintained at a substantially constant value.
  • the tension on sheet 6 may be continuously monitored as it passes around compensator roll 7. If the tension on the sheet rises, regulator 20 increases the speed at which beam 1 releases sheet 6.
  • beam 1 carries a sheet of substantially parallel warp yarns which have been dyed in sheet form by the slasher process.
  • the slasher process allows preparation of a sheet of dyed yarn using any of the available dyes, unlike rope dyeing, which cannot be used for reactive or direct dyes.
  • yarn dyed by the slasher process has only been used for weaving.
  • This invention makes it possible for yarn which has been dyed in sheet by the slasher process to be transferred from a beam to cones for use in making knit fabrics or woven plaid fabrics. Also, if the sheet is made from yarns having different colors which have been wound onto the same beam, the different colored yarns can be conveniently separated and wound to separate cones.
  • the current invention is useful in separating individual yarns which have been dyed in sheet form by the slasher process and wound onto a beam into individual hanks, and then into cones for use in knitted or woven fabrics. Even yarn dyed by Indigo or vat dyes can be used in knitting, as this process allows them to be wound into suitable packages.

Abstract

Procédé et appareil permettant d'enrouler des fils (6a) pour obtenir des écheveaux (19) de 840 yards. Ledit procédé consiste à charger une ensouple (1) autour de laquelle est enroulé un panneau formé d'extrémités parallèles de fils (6a) sur un support rotatif (9), à dérouler le panneau (6) à travers une ligne de contact entre deux cylindres (8) à rotation inverse, à séparer les unes des autres les extrémités parallèles du fil constituant le panneau (6), à guider chacune des extrémités séparées de fil vers un dévidoir rotatif (17), à enrouler les extrémités des fils (6a) autour du dévidoir rotatif (17) par rotation de l'ensouple (1) de manière à libérer le fil enroulé autour de ladite ensouple, à faire tourner les cylindres interactifs (8) pour introduire le panneau dans la ligne de contact et à faire tourner le dévidoir pour enrouler chaque extrémité séparée de fil sur le dévidoir (17). La vitesse de rotation de l'ensouple (1) et des cylindres à rotation inverse est régulée de manière que la tension sur le panneau (6) de fils se situe au-dessous d'une valeur prédéterminée. La régulation de la tension permet de réduire les risques de rupture de fil et entraîne l'enroulement des fils (6a) sur les dévidoirs sous forme d'écheveaux lâches. Les fils peuvent alors être facilement déroulés de ces écheveaux lâches (19) et enroulés en cônes pour le tricotage et le tissage.
