Definitions

  • the invention relates to a new improved process for wrapping an elasthane thread and more particularly a wrapped single thread.
  • c '' is to say of the order of 20 to 40 dtex, which is covered by a synthetic thread textured by false twist of 15 to 30 dtex, wrapped at twists of the order of 1500 turns per meter (t / m).
  • the invention overcomes these drawbacks. It aims to perfect the wrapping technique in question in two phases, but which makes it possible to produce threads industrially substantially without torque and which is easy to work without any particular precautions or arrangement.
  • a "partially drawn multifilament synthetic yarn” is a synthetic yarn which has undergone only partial drawing, that is to say only partial molecular orientation.
  • Such threads are well known and are commonly called POY (pre-oriented yarn) or MOY (medium-oriented yarn).
  • POY pre-oriented yarn
  • MOY medium-oriented yarn
  • Figure 1 is a schematic representation of the process of the first phase.
  • Figure 2 is a schematic representation of the second phase process.
  • Figure 3 is a schematic representation of the third phase process.
  • the spindle (4) rotates at around 11,000 rpm in S, which gives a single gimped wire (12) having a twist of around 760 rpm in S.
  • 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 from ACBF with a pot diameter of 140 mm. During this second phase, this coil (10) is fixed.
  • the rotation speed of the spindle (22-24) is about 15,000 rpm in S, which gives the wire (31) a complementary twist of 1500 rpm in S.
  • the wire (31) has a twist of 2260 rpm S (1500 + 760).
  • the finished wrapped yarn (39) has good coverage.
  • This wire is stiff and has substantially no torque. In this way, it can easily be knitted or woven without using anti-spin devices.
  • the elasticity of the fabric is revealed in a known manner, for example during a simple heating.
