Definitions

  • the present invention relates to the production of colored, preferably bulked continuous multifilament yarns by melt spinning.
  • BCF yarns so produced A substantial percentage of the bulked continuous filament (abbreviated as BCF) yarns so produced is used for the manu­facture of carpets and similar types of covering materials where a vividly or characteristically colored appearance is desirable and is obtained by assembling the final bulked or unbulked yarn from a number of filament groups, strands or yarn components consisting each of filaments of one and the same color (termed “monocolored” or “homochromatic” herein), while the filament groups have mutually differing hues or colors so that the final assembled yarn consists of filaments of two, three or more different colors and is termed "multi­colored” or “polychromatic” herein.
  • polychromatic yarns composed of four, five or even six differing homochromatic yarn constituents tend to be substantially more expensive than those of three or less homo­chromatic constituents.
  • Another object of the invention is an apparatus for use in such a method.
  • the method according to the invention is characterized in that the spinnerets are arranged in at least two mutually distanc­ed vertical planes and in that not more than three different homochromatic groups of filaments of any one yarn are extrud­ed from spinnerets arranged in the same vertical plane.
  • polyolefins are a preferred group and poly­propylene is a particularly preferred species.
  • suitable polymers of this type and melt spinning conditions suitable for them are disclosed, for example, in European Patent Application No. 87810568.3 (published after the prior­ity date of the present application) and the patent literat­ure cited therein.
  • the invention provides a novel apparatus for carrying out the inventive method just defined;
  • this melt spinning apparatus includes means for simultaneously producing at least four and preferably at least eight continuous polychromatic multifilament yarns, each yarn being composed of a number of different homochromatic filament groups;
  • the apparatus com­prises a number of extruders (e.g. four, five or six) to pro­vide at least one extruder for each of the differing homo­chromatic filament groups; at least one spinneret for each homochromatic yarn constituent; conduit means, e.g.
  • manifolds and spinning pumps for operationally connecting each spinner­et with one extruder; cooling or quenching chamber means; ass­embling means for combining a number of yarn constituents to form a polychromatic yarn strand; and yarn strand withdrawal means.
  • the apparatus according to the invention is characterized in that the spinnerets are arranged in at least two different spinneret groups; that each spinneret group is substantially defined by a common vertical plane of alignment; that each of the combined means is supplied from spinnerets of both spinneret groups; and that not more than three spinnerets for any given yarn are arranged in one common plane.
  • Fig. 1 shows the extruding ends of four pairs 10, 12; 11, 13; 14, 16; 15, 17 of spinneret groups defined by and aligned in parallel and subst­antially vertical planes P1 and P2 indicated in dash-pointed lines.
  • the first spinneret group 10 includes two sub-groups a1, b1, c1 and a2, b2, c2 of spinnerets corresponding, for example, with a first set of filaments of three differing colors (colors a, b and c) while the second spinneret group 12 includes two sub-­groups d1, e1, f1 and d2, e2 f2 corresponding, for example, with a second set of three differing colors (colors d, e and f).
  • 1 includ­es at least about 15 openings (not shown) in a generally regular and preferably circular array for extruding 15 (or more) fila­ments from each spinneret (represented by a circle in Fig. 1).
  • the 15 (or more) filaments that are extruded from a single spinn­eret are said to form one "group".
  • the extruded filaments are collected at the lower end of quenching chutes 241, 242.
  • a first yarn 1 composed of filament from spinnerets a1, b1, c1, d1, e1, f1
  • a second yarn 2 composed of filament from spinnerets a2, b2, c2, d2, e2, f2 are assembled.
  • yarns 3-8 are assembled from corresponding a/b/c and d/e/f constitu­ents.
  • a yarn is formed of filaments emanating from 6 differ­ent spinnerets and if the yarn is to comprise only 4 or 5 diff­ering colors, one or two spinnerets will produce filaments that are uncolored or have the same color as those from one of the other spinnerets.
  • the plant illustrated in Figs. 2A, 2B and 2C includes 6 extruders 21 with subsequent spinning units 22 in which the spinnerets are arranged in two distanced planes P1 and P2.
  • the extruded filaments are quenched in quenching un­its 24 having parallel chambers 241, 242 supplied with cooled air via conduit 25 and are fed out via deflectors 26 into a con­ventional stretching device 27 for a molecular orientation.
  • Pow­er supply and automated control units are arranged at 29 and a control panel 291 provides for manual control and settings.
  • Stretching in a device 27 including friction rollers that oper­ate at differential speeds, as well as passage through a textur­ing device 271 and final winding of the assembled yarns 1-8 in pairs on winding mandrel 28 is apparent from Fig. 2B but does not require a detailed explanation because such arr­angements are well known in the art.
  • a preferred filament deflector device for use in the assembly means 26 (Fig. 2A) is illustrated in a diagrammatic front view in Fig. 3A and in a side view in Fig. 3B.
  • a pair of end plates 31, 32 supports two elongated rods or bars 33, 34 and provides a pair of circular grooves 311, 321 for slindingly guiding a half-cylindrical shield 38 which may be provided with a numb­er of shallow grooves on the outside of shield 38.
  • Lower bar 34 supports a number of filament guides 35 made of a ceramic or the like resistant material. Each guide is prov­ided with a small hole (not shown) through which a spinning oil can be supplied from a conduit 37 and through a number of connector tubes 371.
  • the shield 38 For starting up, the shield 38 is moved into a position in which it covers the filament guides 35 so that the start-up filaments run on the outer side of shield 38. Upon commencement of regular operation, shield 38 is mov­ed to uncover filament guides 35 so that the filaments will be drawn into the guides and supplied with spinning oil.
  • Circular and mutually exchangeable spinnerets are preferred for the inventive method and apparatus; typic­ally, a spinneret will have 20, 30 or more openings to produce filaments with a denier in the range of from about 1 to 15 den per filament to obtain yarns in a denier range of from about 40 to about 800 den (yarn total).
  • Typical polychromatic yarns made according to the invention include four, five or six different monochromatic yarns, e.g. red/blue/black/white, red/blue/yellow/black/white and red/­indigo/yellow/black/white/light blue, etc. Use of more than six colors in a polychromatic multifilament yarn does not normally provide additional benefits. Polychromatic yarns con­sisting of four or five differing homochromatic filaments are generally preferred.
  • a "common plane” or “plane of alignment” of spinnerets is gen­erally assumed herein to be an essentially flat, i.e. not curv­ed vertical plane; preferably, at least three spinnerets should be aligned such that the vertical lines through the geometric cen­ters of each of these three spinnerets are essentially situat­ed in such a common plane.
