Definitions

  • the invention relates to the manufacture of yarns from a well-aligned assembly of any type of staple fibre or fibre blend.
  • the constituent fibres are processed such that they are firstly untangled and separated from each other in a carding process and then reassembled into a continuous structure in which the fibres are substantially mutually parallel.
  • the parallel arrangement of the fibres is improved in the subsequent processes of drawing or gilling, which also serve to straighten fibres which may be individually hooked, and may be further improved during an optional combing process which also serves to remove very short fibre, small accumulations of fibre which may still be entangled, and pieces of non-fibrous foreign contaminant.
  • the fibres are assembled into a long continuous rope-like structure of the desired linear density appropriate to the particular spinning machine.
  • the fibre assembly may at this stage be either a sliver, or a lighter material known as roving. Roving may or may not contain twist, but even when twist is present the fibres remain highly parallel to each other in helical paths within the roving structure. Similarly after spinning the fibres remain in parallel helical paths within the yarn structure.
  • a yarn from such a well-aligned fibre assembly does, however, have some disadvantages.
  • the drafting means usually a roller pair
  • its position relative to other fibres simultaneously being drawn into the yarn remains substantially constant, so that as it is twisted about other fibres in the twisting zone to form the spun yarn structure, it takes up a helical path of substantially constant radius. Consequently, the yarn is composed of fibres lying in parallel helical paths.
  • the tensile strength and stability of such yarns depend only upon inter-fibre frictional forces deriving from the internal yarn pressure, which, in turn, derives from the helical fibre paths and fibre tension when the yarn is placed under a tensile stress.
  • the yarn is subjected to a cyclically varying stress, however, there can occur some incremental inter-fibre movement or drafting, leading eventually to yarn breakdown by drafting. This is accentuated when surface fibres are continually being stripped from the yarn which reduces the twist factor and hence reduces the internal yarn pressure.
  • fibres which lie wholly close to the yarn surface are subject to relatively few contacts with other fibres and so are more readily able to draft rather than develop tension when under stress.
  • Yarns spun from well-aligned fibres by conventional means have a small degree of resistance to these problems because many fibres do not remain strictly at the same radius about the yarn axis, but may lie in a helical path of varying radius. This variation in radial position of the fibre is known as fibre migration.
  • Two causes of migration which can occur during conventional spinning are described in the literature.
  • the 'tension mechanism' is due to the tension of fibres on the outside of the forming yarn progressively increasing because of their greater path lengths so that they force their way inwards to replace inner fibres which have gone slack. It has been proposed that this mechanism is hindered by higher overall spinning tension.
  • the 'geometric mechanism' occurs if the twisting is of a form known as the wrapped ribbon form and requires the fibres to change their position in the ribbon emerging from the front roller nip. In ring spinning, for example, the fibre position under the front roller nip is unlikely to change much because of the draft employed, and so the geometric mechanism is of little significance. These naturally occurring mechanisms of migration do not however result in a yarn capable of withstanding the vigorous mechanical action of certain processes such as weaving.
  • the weaving process includes an abrasive action on the warp by the reed and heddles, a cyclically varying tensile stress due to the shedding and beat-up motions, and a cyclic rotation (amounting to repeated untwisting and twisting of the yarn) due to the rubbing action of moving machine parts.
  • Singles yarns spun from well-aligned slivers or rovings invariably fail during weaving by the mechanisms described above, and are almost universally considered unsuitable for weaving as warp. In order to overcome these deficiencies such yarns are commonly twisted together to form twofold or threefold yarn structures to be woven as warp.
  • the plying process may be imitated at the spinning frame by combining, within the twisting zone, two rovings initially separated in the drafting zone.
  • GB-A-1318413 is an example of this.
  • Superimposed on the net yarn twist is a small level of false twist which is generated in the two drafted strands which effect the entrapment of the surface fibres of one strand by the other strand. Further, loose surface fibres rotating about one strand are also trapped by the other strand. While this allows a more compact and slightly finer warp yarn to be produced it still requires two rovings to be prepared for each yarn, and still cannot be spun as fine as a conventional singles yarn.
  • an adhesive usually natural or synthetic size
  • the size solution will penetrate into the body of the yarn, coating all fibres to also reduce the risk of incremental drafting under the cyclically varying forces applied during weaving.
  • this expedient has the disadvantages of the added costs of the sizing process, drying the sized yarn, and subsequently washing off the size during finishing the woven cloth.
  • An object of the present invention is to provide a yarn structure spun from a well-aligned sliver or roving, in which the fibres do not lie in parallel helical paths of constant radius and none of the fibres lie wholly on the yarn surface, and part, or parts, of every fibre is bound within the yarn structure by part or parts of other fibres in the yarn.
  • Another object of the invention is to provide in a singles yarn structure, a degree of additional fibre migration and inter-fibre entanglement to enhance the yarn performance by inhibiting removal of individual fibres from the yarn structure.
  • Another object of the invention is to provide a singles yarn structure, spun from a well-aligned sliver or roving, which is weavable directly as warp without the need of sizing or plying.
  • a further object of the invention is to provide a method and means for modifying the paths of fibres during, and as part of the spinning operation, so as to generate increased levels of fibre migration within the yarn structure.
  • This object may be achieved in a number of ways, for example by cyclically varying the tension of individual fibres as they enter the forming yarn; by bucking and disorienting the fibres before they receive twist; by arranging for small groups of sub-groups, of fibres to twist into discrete strands with false twist prior to the final convergence of all of the fibres into the yarn with real twist; or by any combination of these effects.
  • a yarn structure spun from an aligned sliver or roving, wherein fibres of the sliver or roving after spinning do not lie in normal parallel helical paths of constant radius as the fibre geometry is disturbed by fibres which have been caused to migrate cyclically or randomly between the yarn surface and the interior of the yarn structure and none of the fibres lie wholly on the yarn surface and part, or parts of every fibre is bound within the yarn structure by part or parts of other fibres forming the yarn.
  • a method for producing yarn according to the above wherein migration of fibres between the interior and the surface of the yarn is caused by cyclically varying the tension in individual fibres at a point of twist insertion such that a proportion of the fibres are subjected to high tension whilst simultaneously a second proportion of the fibres are subject to low, or zero, tension.
  • an apparatus for producing yarn comprising front drafting rollers to deliver a strand of fibres, said front drafting rollers forming a nip that constrains the fibres comprising the strand into a ribbon of finite width as they enter and emerge from the nip characterised by an oscillating guide sited downstream of the drafting rollers which is oscillated along a line, or within a plane, parallel to the nip of the rollers, so that when the guide is at its extreme left-hand position a fibre emerging from the nip at the right-hand side of the fibre stream is subjected to a high tension, whilst a fibre emerging from the left-hand side of the nip is at a low tension, and vice versa.
  • a drafted strand of fibres 1 is delivered by the front drafting rollers 2 to pass through an oscillating guide 3, a pigtail guide 4, a further yarn guide 5 (such as a ring and traveller mechanism) which guides the spun yarn 11 to be wound onto a storage package on a spindle 6.
  • the drafted strand 1 passing through the nip 7 of the front drafting rollers is spun into yarn 11 which then passes through the oscillating guide 3 which is shown in its extreme positions of oscillation.
  • the fibres comprising the drafted strand 1 are spread over a finite distance X as they enter and emerge from the nip 7.
  • the oscillating guide 3 is at its extreme left-hand position a fibre 9 emerging from the nip 7 at the right-hand side of the fibre stream 1 is subjected to a high tension, whilst a fibre 10 emerging from the left-hand side of the nip 7 is at low tension or slack.
  • the difference in tension between fibres 9 and 10 causes the fibre 9 to migrate towards the core of the yarn 11 and the fibre 10 to migrate towards the surface of the yarn 11.
  • the oscillating guide 8 moves to its extreme right-hand position (dotted) fibre 10 is now tensioned, causing it to migrate towards the core of the yarn 11, whilst fibre 9 becomes slack causing it to migrate towards the surface of the yarn 11.
  • All other fibres in the strand 1 between fibres 9 and 10 are also subjected to cyclic variations of tension, causing each of them to migrate to some degree within the body of the yarn 11, thereby disrupting the parallel fibre arrangement.
  • the frequency of oscillation of guide 8 is such that fibres are caused to migrate between the surface and the core of the yarn at least three times over a distance along the yarn equal to the mean fibre length to ensure adequate fibre entrapment.
  • FIG. 3 the path of a fibre 10, delivered at the left-hand side of the fibre stream 1 in Figure 2, is depicted as a full line migrating from the surface of the yarn 11 to the core, back to the surface and finally back to the core.
  • a fibre 9, delivered from the right-hand side of the fibre stream in Figure 2 is depicted as a broken line, following a similar path between the core and the surface of the yarn, but 180° out of phase with the path of fibre 10.
  • each of the fibres 9 and 10 become bound within the yarn structure, first the one by the other then the other by the one, successively, along the length of the yarn, and similarly acting upon and being acted upon by every other fibre within the yarn cross-section.
  • an additional pair of nip rollers 12, immediately downstream of the front drafting rollers 2, is driven (by means not shown) at a surface speed less than the delivery speed of the front drafting rollers.
  • the drafted strand 1 is now caused to buckle in the zone between the nips 7 and 13 of the two pairs of rollers and to migrate to-and-fro across the nip 13 of the additional rollers 12 in order to accommodate the lower speed of the additional rollers.
  • a given fibre 14 just entering the overfeed zone can cross that zone unimpeded at the delivery speed of the front drafting rollers 2 until it is caught up by the nip 13 of the additional rollers 12.
  • the fibre 14 has the chance to change its position relative to the main stream of fibres 1, with the possibility of becoming located on the opposite side of the main fibre stream as shown, or at least located with some other different relativity.
  • a fibre leaving the grip of the front drafting rollers will no longer be under the influence of the buckling action and also has the chance to change its position relative to the main stream of fibres.
  • fibres within the main stream may change their position relative to others under the buckling action as a consequence of their individual nature, variations in their bending rigidity along their length, fibre crimp and air turbulence in the region between the two nips.
  • every fibre passing through the overfeed zone has the possibility of changing its relative position as the main fibre stream buckles, spreads under the buckling action and is caused to migrate to-and-fro within the nip of the additional rollers.
  • FIG. 6 depicts in plan the fibres in the drafted strand 1 spread over a wide front of width X within the nip 7 of the front drafting rollers 2 (or similarly within the nip 13 of an additional pair of rollers 12), and being drawn together by the condensing action of twist into a yarn 11.
  • sub-groupings 15 of fibres may form downstream of the roller nip 7 (13), the fibres in each sub-group becoming twisted together in separate sub-strands by false twist which generates by the action of spinning twist under these geometrical conditions.
  • the sub-groups of fibres form and decay relatively rapidly and randomly, and individual fibres can migrate from one sub-group to another, contributing to two or more sub-groups within the yarn structure.
  • loose fibre ends protruding from the surface of a fibre sub-group will rotate with the rotating sub-group under the influence of twist insertion and will be constrained and possibly captured as they pass between neighbouring sub-groups. These trapped loose fibre ends will thus be bound into the yarn structure as the sub-groups converge thereby reducing yarn hairiness as well as increasing the overall fibre binding within the yarn structure.
  • this invention there is provided a variety of methods and apparatus for spinning a yarn from a well-aligned sliver or roving in which part or parts of all of the fibres are bound within the yarn structure by part or parts of other fibres in the yarn such that no fibres exist lying wholly on the surface of the yarn and the fibres do not lie in parallel helical relationships over a significant length within the yarn structure.
  • this yarn exhibits a significantly increased resistance to abrasion, loss of fibre or general breakdown of the yarn structure during further processing as yarn, or during use or service in end products.
  • the yarn is also significantly less hairy than conventionally spun yarns with greatly increased resistance to yarn failure during weaving, and is economically weavable.
  • the yarn may be spun from a single end of sliver or roving, or by drafting two or more slivers or rovings together, side-by-side and in close contact, to improve the yarn evenness through the effect known as doubling, or, through the rovings differing for example in colour or fibre type, to provide an effect yarn.
