Further, these yams occupy less space across the width of the regular beam due to the fine count that leads to the slippage of the overlapped yarns and uneven tension in the warped yarns. Hence regular beams cannot be used for warping the fine count high twisted yarn.

  • Another embodiment of the present invention comprises a method of direct warping of the high twisted yarns onto a warp beam.
  • the method of direct warping comprises warping of the yarns at high tension onto a narrow width beam to avoid slacking and entanglement of the yarns and to maintain the yarn warped in straight condition with substantially even tension among the warped yarn.
  • the method of dying of the high twisted yarns such as voile yarns on a slasher dyeing machine comprises; assembling predetermined number of warp beams on creels to obtain required number of the yarns in a yarn sheet; wetting, dyeing washing and drying the yarn sheet; subjecting each dried yarn in the yarn sheet to high tension in the leasing zone thereby gradually separating of each yarn in the yarn sheet before the yarn reaches leasing rod; and winding the yarns on a weaver's beam.
  • Each individual yarn is substantially subjected to a tension more than 20% of breaking strength of individual yarn the yarn.
  • embodiment of the present invention presents a comb to guide and allow passage of the yarns parallel to each other without entanglement comprising a base and plurality of flexible pins extending parallel from the base wherein the pins are free to oscillate radial direction of the yarn passage, which allows passing the yam without entanglement.
  • the embodiments of the present invention allow dyeing of the voile yarns on the slasher dyeing without entanglement, grouping and/or breakage of the voile yarns. Further, warping apparatus of the present invention can be used to produce weaver beams of the all type of the yarns for various constructions of the fabrics.
  • Fig 1 shows an apparatus of direct warping according to present invention.
  • Fig 2 shows a regular warp beam and a regular warp bam having an arrangement according to the present invention.
  • Fig 3 shows a comb according to the present invention.
  • Fig 4A shows magnified view of the warp beams mounted on creels of the slasher machine.
  • Fig 4B shows slasher machine used for dyeing;
  • Fig 5 shows magnified view of a leasing of yarn in leasing zone with lower tension and higher tension in the yarn.
  • the present invention provides embodiments comprising an apparatus for warping yarns, a comb, method of direct warping of the high twisted fine count yarns and method for dyeing of high twisted fine count yarns on slasher dyeing machine.
  • the apparatus comprises a narrow width warp beam, a comb having flexible pins and is configured to high tension which enable direct warping of the high twisted fine count yarns such as voile yarns.
  • the method of direct warping comprises warping of the yarns at high tension onto a narrow width beam.
  • the method of dyeing of the high twisted yarn includes preparing of the beams having high density of high twisted fine count yarns on narrow width of the beam, and dyeing and separating at high tension.
  • the apparatus (100) for direct warping of yarn onto a warp beam (130) essentially comprises plurality of creels (110) for mounting yarn bobbins (112), a comb (120) for passing the yarns (114) straight onto the warp beam (130) and a pressure roller
  • the yarn is the high twisted fine count yarn such as voile yarn.
  • the high twisted yarn are of entanglement nature and has tendency to form groups, accordingly in present invention, regular size of the warp beam (130) arranged and constructed with narrow warping width (w) by introducing two parallel flanges (134) as shown in Fig 2.
  • a warp beam having narrow width can be used.
  • the warping width of the warp beam according to the present invention can be approximately reduced to half of the original size of the warp beam such as 1200mm width beam is reduced to 500mm.
  • the apparatus is configured to maintain high tension in the yarn while warping which in combination with the narrow warp width (w) of the beam (130) warps the yarns (112) in straight condition with even tension without entanglement and grouping.
  • the tension in the yarn is increased by using conventionally known tensioners (not shown) and/or by known ways.
  • the tension for warping voile yarns is maintain more than 12% of breaking strength of the individual yarn for the direct warping of the voile yarns.
  • the pressure drum (134) is adapted in contact with the warp beam (130) to accommodate reduced width of the flanges (134) at warping stage by reducing size as shown in Fig 1.
  • the pressure drum (132) reduces the tension variation in yarn and prevents twisting of yarns together during dyeing. Further, the pressure drum (132) prevents warp beam bulging that may result in reduction in the warp beam density. Further, the pressure drum prevents slippage of yarn while winding onto the warp beam and entanglement of yarn on the warp beam. This facilitates uniform unwinding of the yarn at the dyeing creel. This facilitates uniform unwinding of the yarn at the dyeing creel. This facilitates uniform unwinding of the yarn at the dyeing creel.
  • Fig 3 shows a comb (120) according to the present invention.
  • the comb (120) has flexible pins (122) extending from the base (124). As another end of the pins (122) is kept free, the pins (122) are free to oscillate in radial direction of the yarns.
  • the oscillation (X) of the flexible pins lessen the vibration of the yarn during warping process thereby avoiding the entanglement and breakage of the high twisted fine count yarn such as voile yarn.
  • length of the comb depends upon the warp or winding width of the beam and number of the flexible pins depends upon the number of the yarn ends.
  • the flexible pins are made of flexible material such as metal and preferably stainless steel.
  • the present invention also provides a method for direct warping of the high twisted yarn such as voile yarns.
  • bobbins having high twisted yarn are assembled on the creel for direct warping and the ends of the yarns are passed through the comb for winding on a narrow warp beam.
  • the yarns are warped on the warp beam having narrow warping width at a tension more than 12% of the single yarn strength.
  • the tension in the yarn and narrow width of the warp beam helps to increase in the density of the yarn ends thereby warps the yarns in straight condition with substantially even tension in the yarns warped with decrease in the slippage of the overlapped yarns. This enables further processing of the high twisted yarns such as dyeing on slasher machine without substantial entanglement nature and breakages of the yarn.
  • the present invention provides a method for dyeing voile yarn, particularly, indigo dyeing voile yarn on slasher dyeing machine (200) as shown in the Fig 4.
  • the warp beams (210) of high twisted fine count yarns such as voile yarns are prepared by direct warping method of the present invention and/or by using apparatus of the present invention.
  • These warp beams (210) are assembled on creels (220) of the slasher machine as shown in Fig 4A.
  • the yarns are pulled from the creels as shown in the Fig 4B by know way to form yarn sheet (230).
  • the yarn sheet (230) is wetted in wetting zone, dyed in the indigo dyeing zone, washed in the washing zone and dried in the drying zone as per know way.
  • the tension in the individual yarn in the yarn sheet in the respective zone is maintained high and gradually increased in each zone than the known method of slasher dyeing, where tension normally gradually increases from 375 Newton to 470 Newton for example in the present invention, the tension starts and increases from 500 Newton to 625 Newton for the voile yarns.
  • the dried yarn sheet further subjected to a tension of more than 20% of single yarn strength multiplied by number of yarns in the sheet in the leasing zone as shown in Fig 5 to separate the voile yarns for winding on a weaver's beam (not shown).
  • the increase in the tension of yarn in the leasing zone of the dyeing process causes separations earlier as shown in Fig 5, which shows separation of dyed yarns by dotted lines at low tension and separation of the yarns in the dyed yarn sheet at high pressure.
  • the separation of the yarns much prior before leasing rod (240) substantially due to high tension lessens the yarn entanglement in the path, yarn breakage and band formation.
