Definitions

  • This invention relates to the production of textile fibre strand, for example, a consolidated sliver or roving produced by a carding or a carding and speedframe operation.
  • a card web is divided into slivers which are consolidated for ease of winding into firm packages and further handling and processing particularly by rubbing aprons which impart twist or false twist to the sliver.
  • the rubbing aprons and associated equipment are bulky and cumbersome and relatively slow in operation.
  • the present invention provides an efficiency-improving replacement or alteration.
  • the invention comprises a method for producing a textile fibre strand comprising the step of consolidating a sliver following a carding operation producing the sliver by passing the sliver through an air jet process.
  • the air jet process may comprise air jet twisting.
  • a card web may be divided into a plurality of slivers, each sliver being individually passed through an air jet process.
  • the air jet process may be accompanied by a rubbing apron process and may precede the same.
  • the sliver may be subjected to a fibre setting operation especially so whilst fibre twisted by the air jet.
  • the air jet may false twist the sliver up to a twist stop located upstream of the air jet.
  • the invention also comprises apparatus for producing a consolidated textile fibre strand from a sliver produced by a carding operation comprising air jet means located adjacent a carding machine and arranged to receive and consolidate a sliver from the carding machine.
  • Apparatus according to the invention for producing consolidated textile fibre strands from sliver produced by a carding machine may comprise an array of air jet means each adapted to receive one of a plurality of slivers divided from the card web produced by the carding machine.
  • the machine may comprise rubbing apron means associated with the air jet means (or with the carding machine).
  • the rubbing apron means may be arranged to receive consolidated sliver from the air jet means.
  • Thermoplastic web fibres may be shrunk before encountering the air jet means, especially in the case of acrylic fibres, by subjecting them to a heat treatment.
  • Adjacent slivers may be differentially heat treated as by one being left untreated and one being heated so as e.g. to shrink the fibres, the two slivers being combined together in one air jet means.
  • Fibres that respond to steam treatment may be so treated for example for shrinkage or to set them in twisted form.
  • the air jet means may be of the entangling rather than the twisted type, of course, although different results can clearly be anticipated from the two types.
  • the drawings illustrate methods and apparatus for producing a textile fibre strand 11.
  • the methods comprise consolidating a sliver 12 following a carding operation producing the sliver, by passing the sliver 12 through an air jet means 13.
  • the jet means 13 illustrated in Figures 1 and 2 comprises a twisting jet 21 having a venturi section 21a and offset jets 22.
  • the jet means 13 false twist the sliver back to twist stop means 24 adjacent the carding machine, the twist stop means comprising nip rollers 24a, 24b.
  • the resulting strand is better consolidated than a strand that has not been subject to an air jet process and can be wound up into a firmer package with less liability to break.
  • the action is akin to the action of rubbing aprons but can be applied more easily and much faster.
  • a rubbing apron may be used as an auxiliary.
  • Figure 3 illustrates how an array 31 of air jet means 13 can be used to consolidate a plurality of slivers 32 from a carding machine 33 the slivers being divided from a single card web produced by the machine.
  • Figure 6 illustrates how a false twisting air jet means 61 can be used with a heater 62 for setting false twist in the sliver 63.
  • False twist exists in the zone between the false twist device and the carding machine and with thermoplastic yarns, heating may set in some of the false twist, the memory of the set twist remaining after untwisting as the strand passes through the false twisting air jet means 61.
  • Figure 7 illustrates false twisting air jet means 71 supplied with two slivers e.g. of acrylic yarn which shrinks on heating.
  • One sliver 72 is from a heater 73, the other not. That from the heater 73 is shrunk, the other is not.
  • the fibres have differential shrinkage.
  • entangling jet means in which the fibres are entangled the better to cohere together as a textile entity.
  • the type of air jet means and the operating air pressures will be similar to those used in texturising continuous filaments by air jet false twisting or tangling.
