Definitions

  • the present invention relates to a method for the production of yarn from a roving of staple fibre material.
  • roving is understood to include twist-free or substantially twist-free fibrous slivers,
  • Revolution numbers up to 20,000 revolutions per minute are already being used and by this means a yarn production of 40 111. per minute can be reached, but, although owing to the progressive refinement of technique a further increase of the allowable number of revolutions is not excluded, yet this matter continues to form a decisive impediment to any important increase of the speed of production.
  • Another limitation of production speed is met with in drawing the roving to form a thin fibrous sliver.
  • speed of the delivery rollers of the drawing device is too high, the fibres are torn from the roving supplied by the feeding rollers at such a rate as to cause a disruption of the coherence among the fibres giving rise to interruptions in the fibrous sliver, which means ruptures in the yarn.
  • the method according to the present invention has the characterizing feature that the roving is subjected to a number of treatments, among which the treatments that are of importance for yarn formation exclusively consist in bringing the roving into a wet condition,'drawing the said roving at a great speed to form a thinner fibrous sliver, false-twisting the said fibrous sliver, winding the fibrous sliver into a fibre packet in the shape of a cross-wound bobbin and sizing the fibre packet so as to form an unwindable yarn packet.
  • the treatments that are of importance for yarn formation exclusively consist in bringing the roving into a wet condition,'drawing the said roving at a great speed to form a thinner fibrous sliver, false-twisting the said fibrous sliver, winding the fibrous sliver into a fibre packet in the shape of a cross-wound bobbin and sizing the fibre packet so as to form an unwindable yarn packet.
  • a wet condition of fibrous material is understood to mean the presence of so much water as to have it adhering to the surface of the fibres as free water, such in contradistinction to a humid condition, in which the water has been entirely absorbed by the fibres.
  • a cross-wound bobbin is understood a coil the turns of which only touch each other when crossing.
  • the fibres owing to the roving being drawn in wet condition, show such a firm coherence as to make it possible for an uninterrupted and smooth thin sliver to be formed specially at high delivery speeds of the drawing device and the smoothness of the yarn improves as the speed increases.
  • This may perhaps be attributed to, forces of mass inertia, viscous forces and surface tensions, which cause more regular differences in speed between the fibres while being drawn.
  • drawing is effected at a delivery speed of at least 50 m. per minute.
  • the water to be used for wetting the fibrous material should contain dissolved or suspended additives. It is possible, however, to use such additives with a view to later treatments of the yarn or for the obtention of special properties.
  • the drawing of the roving is effected on a drawing device comprising two or more pairs of rollers and in which the roving runs between two successive pairs of rollers through a free drawing field.
  • a drawing device comprising two or more pairs of rollers and in which the roving runs between two successive pairs of rollers through a free drawing field.
  • the false-twisting causes the coherence of the fibres to be temporarily increased after drawing to such an extent as to render the sliver strong enough to cover the distance between the drawing device and the winding device and to resist any tensile stresses it may meet with on its way.
  • a pneumatic false-twisting device it is usual for a pneumatic false-twisting device to be employed in false-twisting.
  • the fibrous sliver is guided through a mainly cylindrical bore, into which a number of blowing nozzles open in a tangential way.
  • a rotating air column forms within the bore, the rotation of the said air column being transmitted on to the passing sliver.
  • the number of its revolutions may easily be increased to such an extent that in this respect no limitation Whatever of the speed of the yarn is met with.
  • the sizing can be effected by using a perforated core when winding the fibre packet and by introducing the sizing agent into the packet by means of this core.
  • this method it is difiicult to obtain an even concentration of the sizing agent in the packet and to maintain it.
  • the drying process, during which hot air is blown through the packet by way of the core will give rise to migration phenomena, with the result that the content in sizing agent of the yarn can not have the desired value in all places.
  • the method according to the present invention is preferably carried out in such a way that the sizing agent required for the sizing of the fibre packet is added to the roving in a non-active form and that the fibre packet is subsequently subjected to a treatment that activates the sizing agent.
  • Another possibility is that, for instance, when starch is being used as the sizing agent, the roving, which is in an unsaturated wet condition, is washed with an excess supply of starch-grain suspension, after which the fibre packet is subjected to a heat treatment, the temperature, the environmental moisture and the duration of which are adapted to the gelatination of the starch grains present in the fibre packet, and subsequently dried.
  • a combination of these two methods is also possible. As has been found, these methods do not give rise to any migration phenomena of the starch in the packet.
  • the method according to the invention offers the additional advantage that any further treatments of the fibrous material that may be necessary, such as bleaching, dyeing, mercerizing, or rendering the material self-ironing (no iron), fire-resistant or rotproof, can be carried out while it is still in the roving stage, so that these treatments can work themselves out more fully and sometimes can be carried out in a more economical way, because the roving is already in the wet condition in view of the further working-up into yarn.
  • any further treatments of the fibrous material that may be necessary, such as bleaching, dyeing, mercerizing, or rendering the material self-ironing (no iron), fire-resistant or rotproof
  • the yarn which is obtained by the method according to the present invention is twistfree or, such in connection with the twist of the roving and the twist which may have been given to the yarn through the unwinding of the packet in axial direction, substantially twist-free.
  • the coherence among the fibres is entirely obtained by means of the glueing and is so strong that the yarn can be used as a weaving yarn just as the usual twisted yarns. This implies that a cotton yarn manufactured according to method of the present invention can immediately be used as a warp yarn, whilst a woollen yarn has only to be doubled in the usual manner to obtain the resistance against wear and shock required in a warp yarn.
  • the method according to this invention may also be used for yarns made of other fibrous materials and for yarns consisting of mixtures of different fibres.
  • This invention also relates to yarns which have been manufactured by using the above-described method. It is distinguished from twisted yarns, besides by its entire or substantially entire lack of twist, by its somewhat flat-cross section. When it is used as a single warp yarn, this flatness has the advantage that it easily passes the healds and the reed of the weaving loom and, because it comes to lie flat in the web, it has the effect that the web is of a closer structure than is an otherwise similar fabric of twisted yarn.
  • the roving 1 is drawn to form the thin fibrous sliver 8, which subsequently passes the pneumatic twisting element 9 and the traversing element 10 and is wound up to form a fibre packet 11, which is driven -by the winding roller 12.
  • the roving While passing the guiding elements 3, the roving is washed with a suspension of potato starch in water, which is supplied from the reservoir 15 through the pipe 13 with the control cock 14.
  • An agitator 16 is provided in the reservoir to prevent the suspension from sedimenting.
  • the suspension from the reservoir 15 is also supplied to the delivery rollers of the drawing device through the same pipe 17 with the control cock 18.
  • a circulating band 20 is provided about the rollers 19, one of which is driven by the feeding roller set in the direction indicated at a low speed.
  • the band 20, which presses against the roller 7, brings a thin layer of the suspension, which is supplied through the pipe 17, on to the roller 7, which in turn transmits part of this layer to the fibrous sliver 8.
  • the suspension-content gauge 24 is provided in the pipe 17, by which gauge changes of the suspension can be established and, if necessary, corrected.
  • a cotton roving of 300 tex was wound on roving bobbins, brought into a wet condition by boiling off and defattened and subsequently bleached and dyed.
  • the moisture content was reduced to about by means of suction.
  • the roving was unwound from the bobbins and, after having been washed by the stream of a suspension of 10% of potato starch in water issuing from the pipe 13, it was taken through the drawing device.
  • the compressive force of the feeding rollers amounted to about 1 kg., so that the roving, after it had passed these rollers, had a moisture content of about
  • the drive of the drawing device was arranged in such a manner that the peripheral velocity of the delivery roller set was 15 times as high as that of the feeding roller set and amounted to about 200 m./minute.
  • This twisting element consisted of a cylindrical channel having a length of 6 mm., a diameter of 1.5 mm. and bevelled end parts, and 6 tangential blowing nozzles having a diameter of 0.4 mm. each and having an axial deviation of 5 in the running direction of the yarn.
  • the twisting element was fed with air of 0.4 atmosphere, the air consumption amounting to about 7 l./min.
  • the sliver was wound up on a perforated core in the shape of a crosswound bobbin.
  • the peripheral velocity of the driving roll was about 3% lower than the velocity of delivery of the drawing device, so that unaJlowable tensions in the fibrous sliver were avoided.
  • the sliver had in this way been formed into a packet, the latter was taken from the core and was subjected to a treatment with low pressure steam in an air-free space for 30 minutes. The packet was subsequently dried, after which the sized yarn could be unwound from the packet.
  • a method for the production of yarn from a roving of staple fibre material having insufficient natural sizing agents to be able to form a twist-free yarn wherein the roving is subjected to a number of treatments, among which the treatments that are of importance for yarn formation exclusively consist in bringing the roving into a wet condition, drawing the said roving at a great speed to form a thinner fibrous sliver, false-twisting the said fibrous sliver, winding the fibrous sliver into a fibre packet in the shape of a cross-wound bobbin and sizing the fibre packet so as to form an unwindable yarn packet.
  • nonactive but activatable sizing agent applied to the roving is a starch-grain suspension and wherein the fiber packet is subjected to heat treatment, the temperature, the environmental moisture and the duration of which is adapted to gelatinize the starch-grains present in the packet, and subsequently drying said fiber packet.
