Definitions

  • the processes to which the roving is subjected includes the wet drafting of the roving at great speed to form a thinner fibrous sliver and the bonding of said fibrous silver. At least one of the fibre components, of which the staple fibre material is composed, provides for this bonding.
  • the invention relates to a method for the manufacture of yarn from a roving of staple fibre material formed of at least two components.
  • the method includes drafting of the roving to form a thinner fibrous sliver at great speed and the bonding of this fibrous sliver.
  • the bonding of the fibrous sliver is necessary if the method is applied to the manufacture of twist-free yarn or yarn with a relatively low twist.
  • a method for the manufacture of twist-free yarn is described in ITS Weaving l/l97 l pages 29, and 37, where the drafting of the roving to form a thinner fi brous sliver takes place in a dry condition, whereupon the bonding of the fibrous sliver so obtained is effected by the supply of an active bond and subsequent drying.
  • the bonding of the fibrous material occurs as follows: the roving, which is in an unsaturated wet condition, is washed with an excess supply of starch-grain suspension, after which the fibrous sliver wound to a fibre package 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 package, and subsequently dried.
  • the object of the present invention is to provide a completely new method of bonding .the roving, in which the bonding agent is not added to the fibrous material during the afore-mentioned process itself.
  • the staple fibre material according to the invention is formed of components at least one of which provides the bonding.
  • the bonding agent required for the bonding of the fibrous sliver is therefore present in an inactive form. ln order to accomplish bonding of the fibrous sliver, the fibrous component providing for the bonding should be activated after the roving has been drafted to a thinner fibrous sliver. The choice of this fibre component determines the method by which the activation takes place.
  • the roving may contain a natural fibre.
  • fibre component which does not provide for the bonding, for instance such as cotton or synthetic fibres as polyamide, polyester or stabilised polyvinyl alcohol.
  • One of the following types of fibres can be used for the bonding component:
  • fibres which are expandable, gelatinisable or soluble in water such as unstabilised polyvinyl alcohol (PVA) or alginate fibres;
  • PVA polyvinyl alcohol
  • fibres soluble in mixtures of water and suitable organic solvents e.g. acetone, formic acid, acetic acid, etc.
  • suitable organic solvents e.g. acetone, formic acid, acetic acid, etc.
  • melting fibres such as polyamides melting under a relatively low temperature or polyalkylene compounds (polyolefines)
  • a roving in which several of the non-bonding fibres are provided in addition to bonding fibres, such as cotton with polyester and unstabilised PVA as the bonding fibre. It should be noted that not every combination of fibres providing for the bonding with fibres not providing for the bonding can be used.
  • the method used for the activation of the bonding fibres is determined by the type of fibre used for this purpose.
  • unstabilised polyvinyl alcohol, alginate fibres etc. it is necessary to bring the fibrous sliver into a wet condition before bondingu
  • the bonding fibre component causes bonding with and between the surrounding fibre components during the bonding process of the fibrous sliver by expanding, gelatinising, or partial solving, and subsequent drying.
  • a wet condition means in an aqueous medium.
  • dior triacetate fibres mixtures of water and suitable organic solvents can be used instead of water.
  • the process of expanding, gelatinising or partial solving can be accelerated by-performing this process under an increased temperature.
  • lfa melting fibre is used as the bonding fibre component, bonding with and between the other surrounding fibre components during the bonding of the fibrous sliver is achieved by melting this component under an increased temperature or subjecting it to a sufficient surface softening, and subsequent cooling.
  • the fibre material should therefore be in a dry condition before the bonding step.
  • the methods described above for the activation of the bonding fibre components can be applied to a process in which the drafting of the roving occurs in a wet condition and also to a process in which this occurs in a dry condition. Also the two methods of activation can both be applied to the manufacture of twist-free yarn and to obtain yarn with a relatively low twist.
  • the activation of the bonding fibre component can be omitted during the spinning of the yarn with a relatively low twist and be delayed to the moment when higher standards are set to the yarn.
  • the thinner fibrous sliver so obtained should be dried before the bonding process.
  • the roving l which is pulled off the roving bobbin 2, is guided, with the aid of guiding elements 3, through a reservoir filled with water 4 containing an agent that renders the roving more permeable to water, and fed to a drafting device, of which the serrated roller 5 and the rubber roller 6 form the feed rollers and the serrated roller 7 and therubber roller 8 the delivery rollers.
  • the roving is drafted to form a thin fibrous sliver 9, which, subsequently, is passed through the pneumatic false-twisting element 10 and the traversing element 11 and is wound to form a fibre package 12 which is driven by a winding roller 13.
  • the coherence of the fibres was found to be such that, especially with high delivery speeds of the drafting device, an uninterrupted and smooth thin sliver can be formed; furthermore, it was found that the smoothness of the yarn improved as the speed increased.
  • the drafting takes place between the feed rollers and the delivery rollers of the drafting device; here the peripheral speed of the rollers 7 and 8 of the delivery rollers is one order of magnitude larger than the peripheral speed of the rollers 5 and 6 of the feed rollers.
  • the roving runs between the roller pairs 5, 6 and 7, 8 through a free drafting field.
  • the means used earlier in the drafting field such as needles, pins, rollers and belts, for the purpose of increasing the coherence amongst the fibres, were found to exert by this method, as described in said British patent, an adverse influence on the drafting process and on the quality of the yarn.
  • the sliver drawn from the drafting device is then fed to the winding device via the falsetwisting element 10.
  • the false twisting causes the coherence of the fibres to be temporarily increased after the drafting to such an extent as to render the sliver strong enough to cover the distance between the driving device and the winding device and to resist any tensile stresses it may encounter on its way.
  • a pneumatic false-twisting device For false twisting a pneumatic false-twisting device is employed.
  • the fibrous sliver is guided through a mainly cylindrical bore into which a number of blowing nozzles open tangentially.
  • a rotating air column can be formed within the bore, the rotation of the air column being transmitted to the passing sliver.
  • the number of revolutions may easily be increased to such an extent that in this respect to limitation whatever of the speed of the yarn will be encountered.
  • the sliver After passing the twisting element, the sliver is wound on a perforated core and formed into a fibre package 12. During this winding process it is important that no part of the slivers should touch any other part of the sliver lengthwise, because. after bonding, these two parts of the sliver would be joined together so firmly that yarn rupture would almost certainly occur at this place when unwinding the yarn. For this reason it is necessary to use the cross-wound bobbin, the turns of which touch each other crosswise only, as the necessary winding form of the sliver because it has been found that two sliver parts that cross each other after they have been bonded will not form a bonding that is stronger than the yarn itself.
  • the peripheral speed of the drive roller 13 is a little less than the delivery speed of the drafting device, thus avoiding undesirable tensions in the fibrous sliver.
  • the package is taken from the core and is subjected to a steam treatment for some time.
  • the package is then dried and cooled, whereupon the bonded yarn can be unwound from the package.
  • Ne 0.8 roving was used, containing percent cotton and 10 percent PVA fibre; after a 20-fold elongation, a steam treatment for 25 minutes at about 80C and drying at about C, an Ne 16 cotton yarn was obtained. lt was found that the PVA in the fabric, which was obtained by the yarn so produced, could be very easily removed.
  • an Ne 12 viscose fibre yarn was obtained from an Ne 0.6 roving containing 92.5 percent viscose rayon fibre and 7.5 percent PVA fibre, after drafting, steam treatment and drying as in the previous example.
  • a method of manufacturing twistless yarn from a staple fibre material having at least two fibre components, one of which is potentially adhesive upon application at least of moisture including the steps of:
