Abstract

983,638. Making artificial filaments. FMC CORPORATION. Aug. 28, 1961 [May 11, 1961] No. 30954/61. Heading B5B. Artificial filaments are made by dividing a stream of polymeric material in liquid form into a number of individual streams, directing the individual streams along independent but intersecting paths, whereby portions of the different individual streams are blended together as their paths intersect each other, and combining the individual blended streams of polymeric material into a single stream which is then shaped into the filaments. As shown in Fig. 1, a thermoplastic filamentforming material, such as polypropylene, is fed in the form of chips or pellets into the barrel 25 of an extrusion apparatus 15 of known construction and is advanced through the barrel by a rotatable screw conveyer 27. The polymer is heated to the desired melt temperature, e.g. 225‹ to 250‹ C., by heaters 29 encasing the barrel. The melt is forced through a passage 31 in the extrusion block 19 and is delivered by the metering pump 17 into the passage 37 from which it flows through a passage 39 and the helical grooves on the surface of the blending unit 21 and thereafter through the holes in a breaker plate 47 and finally through the extrusion orifices of the spinneret 43. Flow differences within the stream of polymer melt are eliminated by the cylindrical blending unit 21 which fits snugly within the aligned cylindrical passages 39 and 57 and is supported above the breaker plate 47 by the pin 59. The unit 21 is provided on its surface with a number of helical grooves 61 and 63 (Fig. 2) which intersect similar helical grooves 65 and 67 of equal but opposite pitch. The polymeric material may be in the form of a spinning solution, in which case the single stream is shaped into filaments by wet or dry spinning. One or more streams of a polymer melt containing a dispersed pigment may be injected into the main polymer melt stream through a conduit 69, when it is desired to make coloured filaments. Differences between the flow rates of the filament forming material through different orifices of the spinneret are reduced and consequent differences between the diameters of the filaments of multi-filament yarns are reduced by the procedure of the invention.
