Definitions

  • the present invention relates to the manufacture of yarns, threads, twines and like materials. More particularly the invention relates to the manufacture of high bulk yarns made from staple fibre material combined with continuous filaments or pre-spun staple fibre yarns.
  • the total number of fibres in the yarn cross- section is at least an average of 90.
  • a worsted yarn spun from 22 ⁇ m fibres a conventional yarn could be spun to a linear density as fine as 22.5 tex, whereas a high bulk worsted yarn, spun according to the method disclosed in our New Zealand Patent No. 232390 could not be spun finer than 45 tex.
  • a method is disclosed of producing in one operation a yarn comprised of one strand of staple fibre twisted together with two continuous filaments or pre-spun strands.
  • the main advantage of this method lies in its ability to spin much finer yarns with as few as 20 staple fibres or less in the yarn cross- section.
  • a yarn spun by this method a yarn was spun having an average of 26 fibres of a 29 ⁇ wool and two nylon continuous filaments of 4.2 tex each. The resultant count of the yarn was 30 tex whereas a yarn spun conventionally from this wool could not be spun finer than 39 tex.
  • This multi-component yarn has many advantageous properties and end uses, particularly as a weaving yarn, but it has one major disadvantage in that it lacks bulk and it is generally considered unsuitable for many applications in knitting.
  • the bulk of such a yarn is typically in the range
  • An object of the present invention is to produce in one operation a high bulk, fine count staple yarn by combining the technologies disclosed in our earlier New Zealand Patent No. 225679 and New Zealand Patent No. 232390.
  • a further object of the invention is to produce a high bulk, fine count staple yarn in which at least a proportion of the staple fibres is overfed into the yarn structure at the point of twist insertion such that the overfed portion of staple fibre is caused to protrude in loops from the yarn surface to constitute a bulky sheath of fibre.
  • a further object of the invention is to provide a yarn structure having a high initial modulus of extensibility such that the yarn bulk is stable to the tensile stresses normally imposed upon a yarn in further processing steps such as winding, weaving and knitting.
  • a process for producing a yarn comprising staple fibres twisted together with one or more filament or pre-spun yarns on ring or other types of spinning frames or machines which utilise any form of closed-end, long draft system, to form a yarn structure, and in which a proportion of the staple fibre is overfed into the structure to provide a bulky sheath of fibres twisted around a central core consisting of the one or more filament or pre-spun yarns and a second proportion of the staple fibre.
  • a process for producing a yarn comprising staple fibres twisted together with one or more filament or pre-spun yarns on ring or other types of spinning frames or machines, and in which a proportion of the staple fibre is overfed into the structure to provide a bulky sheath of fibre twisted around a central core consisting of the one or more filament or pre-spun yarns and a second proportion of the staple fibre
  • the process including the steps of: mounting in association with a spinning machine one or more packages of single filament, multi-filament yarn or pre-spun yarn and a driven roller means adapted to control the feed of staple fibres between the front rollers of a drafting system and a point at which twist is first inserted between the fibres and filament or pre-spun yarn; dimensioning the roller means relative to the length of the staple fibres and its surface speed relative to the delivery speed of the front drafting rollers so that part of each staple fibre is overfed into the staple fibre strand forming the yarn; feeding one of the filament or pre-spun yarn

  • Figure 5 shows in detail the yarn structure and the paths occupied by a typical staple fibre and the two filament or pre-spun yarns within the structure of a yarn spun on a hollow spindle spinning machine.
  • a second filament or pre-spun yarn 13 may also be fed at low tension into the nip of rollers 4 but in spatial separation from the first filament or pre-spun yarn 12 and the roving 1.
  • the second filament or pre-spun yarn may be fed at low tension into the nip of the driven rollers 5, in spatial separation from the first filament or pre-spun yarn 12 and roving 1, or alternatively of the downstream rollers 5, these alternatives being shown in broken lines.
  • the spindle 10 rotates to insert twist into the yarn structure 7 and to wind a formed yarn onto the package 9 by co-operation with the ring and traveller mechanism 11. The twist inserted propagates upstream in the yarn as far as the nip of the driven rollers 5.
  • the driven rollers 5 are driven with a surface speed in excess of that of rollers 4 by a proportion in excess of unity, chosen according to the particular properties required in the finished yarn 7.
  • the rollers 5 are loaded to provide a pressure at their nip which is sufficient to influence staple fibres after the trailing ends of those fibres have been released by the nip of rollers 4 during their passage through the system, but light enough to allow staple fibres still nipped by rollers 4 and the filament or pre-spun yarns to slip in the nips of rollers 5 without becoming excessively stretched or broken.
  • the second filament or pre-spun yarn 13 may be fed into the system at one of any of the three alternative position 13 shown in Figures 1 and 2, and it is always kept in spatial separation from the first filament 12 and the staple fibre strand 1 until a point is reached downstream of the nip of rollers 5.
  • the second filament or pre-spun yarn 13 is controlled at the surface speed of rollers 4 to be fed into the yarn 7 under the spinning tension of the yarn 7 to become wrapped relatively tightly around the core of the yarn 7.
  • the filament or pre-spun yarn 13 is controlled at the surface speed of rollers 5 to become overfed into the yarn 7 and so becomes loosely wrapped around the core of yarn 7, contributing to the bulky sheath.
  • the yarn 7 may be spun by including one only of the two filament or pre-spun yarns 12 and 13, either as a core or a wrapping component.
  • the filament or pre-spun yarn can assist in carrying the staple fibre component from the nip of the front drafting rollers 4 through the nip of rollers 5 and on into the twisted yarn structure, and further contribute to the tensile strength of the yarn 7.
  • the filament or pre- spun yarn 13 is caused to wrap around the yarn 7, assisting in binding the staple fibres within the yarn structure and contributing to the tensile strength of the yarn 7.
  • a roving of staple fibres 1 is processed through a drafting system as described previously to be delivered via front drafting rollers 4, a pair of delivery rollers 17 to be wound into a package 18 driven by a scroll roller 19.
  • the hollow spindle 14 has at its lower end mechanism 16 designed to grip the yarn with low force sufficient to rotate the yarn, inserting false twist upstream to the nip of rollers 5, but light enough to allow the yarn 7 to be drawn through the mechanism 16 by the delivery rollers 17 without significantly stretching or breaking the yarn 7.
  • a package 15 of a second filament or pre-spun yarn 13 which rotates with spindle 14.
  • the filament or pre-spun yarn 13 combines with the forming yarn 7 by wrapping around yarn 7 under the tension of the balloon formed in the filament or pre-spun yarn 13. Downstream of the yarn gripping mechanism 16 there is substantially no twist between the staple fibres in yarn 7, but there is twist between the filament or pre-spun yarn 13 and the yarn 7 by virtue of the former wrapping around the latter.
  • the driven rollers 5 are driven at a surface speed greater than that of the front drafting rollers 4 to overfeed the trailing portions of staple fibres into the yarn 7 as previously described.
  • a first filament or pre-spun yarn 12 is fed at the nip of rollers 4, also as previously described, to become incorporated into the core of yarn 7 and assist in carrying the staple fibres from the nip of rollers 4 to the point at which the structure is wrapped by the filament or pre-spun yarn 13.
  • yarn may also be spun as hereinbefore described on a hollow spindle machine, but including only one or either of the two filament or pre-spun yarns 12 and 13.
  • FIG. 4 there is illustrated the path in the yarn structure of a typical staple fibre 20 showing the leading end of the fibre firmly twisted into the yarn core with its trailing end loosely twisted into a sheath around the core in a yarn produced according to a first aspect of the invention including two filament or pre-spun yarns 12 and 13. The trailing end is then twisted into the yarn with a lower twist per unit fibre length.
  • the first filament or pre-spun yarn 12 is shown, as a full line, embedded within the core of the yarn structure, and the second filament or pre-spun yarn 13 is shown wrapping the structure, for yarns spun as hereinbefore described on a ringframe.
