Definitions

  • the invention relates to a method for manufacturing elastic wrapped yarn with a spandex and more particularly a method for manufacturing simple wrapped elasthane yarn.
  • the invention overcomes these drawbacks. It relates to a process which is both economical and allows for larger windings.
  • the wrapping twist must be of the order of one third of the usual twist of simple wrapping. If this twist was lower, we would no longer have a covering., But then an assembly in which the elastane thread would not be positioned in the middle, that is to say in the core, but would instead come periodically on the surface, so that during the complementary torsion, this presence on the surface would be accentuated.
  • the thread thus obtained would be fragile, because the elastane thread would be bad protected, therefore subject to pruning.
  • the twist communicated during the first phase is too strong, for example greater than half of the usual twist of simple covering, in addition to the unnecessarily high cost of such an operation, the flash defect would reappear and would be even accentuated after the second phase.
  • FIG. 1 shows in section a rough assembly for the implementation of phase 1
  • FIG. 2 is a rough assembly, seen in section, for the implementation of phase 2.
  • Reception (10) takes place on a spool (11) with a diameter of 120 mm and a stroke of 200 mm.
  • This coil (10) is then placed (see FIG. 2) on a double twist spindle type 2055 of ACBF with a pot diameter of 140 mm. During this treatment, this coil (10) is therefore fixed.
  • the rotational speed of the spindle (22-24) is approximately 15,000 rpm in S, which gives the wire (31) a complementary twist of 1200 rpm in S.
  • the wire (31) therefore has a final twist of 1200 plus 600, i.e. 1800 rpm in S.
  • the coil (30) obtained weighs around 1.5 kg compared to 1 kg in the most favorable cases currently starting with a simple covering machine.
  • the wire (31) obtained has excellent elasticity and very good coverage, so that for most common applications, it is advantageous to eliminate the conventional heat treatments for fixing.
  • This thread is perfectly suitable for the manufacture of woven or knitted fabrics, especially for the bottom legs.
  • This wire (31) can easily be identified in relation to a conventional wrapped single wire. Indeed, in a conventional single guided wire, if the wire is disassembled, the core wire is then communicated with a twist equal to the wrapping twist. Thus, for a wire wrapped at 1800 turns during disassembly, the core wire receives a twist of 1800 turns in Z.
  • the twist in phase 1 is 700 rpm in S while in phase 2, it is 1400 rpm in S, which gives a final twist of 2100 rpm in S.
  • the wire obtained has the same properties as that obtained in Example 1.
  • Example 1 is repeated, replacing the textured thread coating (7) with a raw wire of the same kind and the same title.
  • the twist of the first covering phase is brought to 700 rpm.
  • the rotation of the double twist spindle (22-24) is fixed at 13,000 rpm, which gives an additional twist of 1400 rpm.
  • the wire (31) therefore has a final twist of 2100 rpm in S.
  • Example 1 is repeated, replacing the core thread (3) with a 20 denier elasthane thread stretched four times and the coating thread (7) with a greige polyamide 6.6 thread of 17 dtex / 5 strands.
  • the wrapping twist of the first phase is 850 rpm in S.
  • the additional twist given by the double twist spindle (22-24) is 1650 rpm in S.
  • the finished yarn (31) has a final twist of 2500 rpm in S. This thread is perfectly suitable for the production of tights or stockings.
