Definitions

  • This invention relates to the intermingling of multifilament yarns.
  • Turbulent air flow in the guide is thought to cause the filaments to separate and twist around each other, the twist being propagated upstream and downstream of the yarn to form regions of high coherence known as nips or nodes separated by regions of low coherence in which the yarn filaments remain substantially parallel.
  • Use of such devices has been shown to offer methods of alleviating the above problems although presently there is no commercially available device that totally fullfills these requirements.
  • a method of intermingling one or more multifilament yarns comprising feeding said yarn or yarns along a yarn channel having a uniform V-shaped cross-section throughout its length and admitting at least one fluid stream to said channel in a direction transversely of the channel and at a velocity such that-air turbulence in the channel causes the yarn filaments to intermingle.
  • a device for intermingling multifilament yarns comprising a yarn channel of V-shaped cross-section having-two convergent channel sides bridged by a third side having a yarn entry slot positioned adjacent a fluid channel for admitting a high velocity fluid stream to said channel in a direction transversely of the axis of yarn travelling in said channel in use so as to intermingle the yarn filaments and prevent escape of the yarn from the channel.
  • an intermingling device comprises a rectangular block 1 with side flanges 2 and 3 made in one piece of ferrous material.
  • the flat upper surface 4 of the block 1 is formed with a central V-section yarn channel 5 extending transversely thereof.
  • Midway along the yarn channel 5 is an air inlet 6 disposed in the floor of the channel 5 in the angle between the downwardly convergent sides thereof.
  • the air inlet 6 is the outlet end of a bore in the block 1 having a narrow section 7 and an enlarged section 8 adapted to be connected to a source of air under pressure.
  • the narrow bore section 7 is at right angles to yarn channel 5 in both the plane extending lengthwise of the channel 5 (Fig. 2) and in the plane extending transversely of the channel 5 (Fig. 3).
  • the upper surface 4 of the block 1 has dowel holes 9, 10 for respective dowel pins (not shown) for locating a cover 11 having a lower surface 12, which is congruent with said surface 4 and has corresponding dowel holes 13, 14.
  • the cover 11 may be made of magnetic material in order that it may be held firmly on the block 1 while nevertheless being easily removed and replaced to facilitate yarn thread-up.
  • the flanges 2, 3 have respective bores 15, 16 which are in line with the yarn channel 5 as seen in the plan view of Fig. 1.
  • the bores 15, 16 have respective side openings 17, 18 which are threaded to receive set screws (now shown) for fixing the position of guide posts 19, 20 received in the bores 15, 16 (Fig. 6).
  • Each guide post 19, 20 has a forked upper end which receives a yarn guide element 21, 22 made of ceramic material.
  • each yarn guide element 21, 22 is of generally rectangular shape with a recess in its upper edge comprising a lead-in 23 and a guide slot 24 in which the yarn runs in use.
  • the guide posts 19, 20 are so positioned that the guide slots 24 of the yarn guide elements 21, 22 cause the yarn (Y in Fig. 6) to run in a straight line centrally of the channel 5, i.e. without contacting the sides thereof or the surface 12 of the cover 11 and substantially equidistant from said sides and surface, when no air is entering the channel 5 through the inlet 6.
  • the yarn channel 5 is of uniform V-shaped cross-section throughout its length, i.e. its profile comprises downwardly convergent, substantially planar side walls and does not vary from one end of the channel to the other.
  • the sides of the channel 5 are mutually inclined at an angle of 60° but, although this is the preferred angle, other angles of between 30° and 120 0 are also within the scope of the invention although at the extremes of this range it may be necessary to expend undesirably large volumes of air to achieve the intermingling effect.
  • the second embodiment of intermingling device comprises a self-threading yarn guide block 25 extending between yarn guides 26, 27 (Figs. 10 and 11).
  • the block 25 has a central V-section yarn channel 28 extending therethrough.
  • the yarn channel 28 is of uniform V-shaped cross-section throughout its length and the angle subtended by its downwardly converging sides is 60°.
  • a lateral air inlet 29 enters the yarn channel 28 midway therealong at its upper left-hand edge as viewed in Fig. 12.
  • the yarn channel 28 is connected by a constricted passage 30 to a V-section groove 31 in the upper surface of the block 25 serving as a lead-in for the yarn travelling between the guides 26, 27.
  • the air inlet 29 is connected to a source of compressed air by an air channel 32 (Fig. 10) and a coupling (Fig. 11).
  • the yarn to be intermingled is laid in the yarn guides 26, 27 so as to rest in the lead-in groove 31 of the block 25.
  • the air is turned on a suction effect is created in the passage 30 so as to assist entry of the yarn into the yarn channel 28.
  • Air turbulence positions the yarn centrally in the channel 28 and the incoming air prevents the yarn from re-entering the passage 30 and accidentally escaping from the channel 28.
  • the yarn may be made of staple (discontinuous) fibre of material or synthetic material and the term "filament" is used in the claims to include both continuous and discontinuous filaments or fibres.
  • two or more yarns may be provided simultaneously so as to commingle the filaments thereof and produce a composite yarn.
