摘要： A method and apparatus for melt spinning molten polymeric material into filaments, preferably embodied in the form of a spin pack assembly, utilizes an annular polymer filter formed of a screen mesh material to have a U-shaped axial cross-section defining an open end oriented to face upwardly for receiving polymer within the annular interior of the screen to flow outwardly therefrom to a downstream spinneret for extrusion. The filter eliminates any need to utilize sand or other filter material contained by the screen as a primary or auxiliary filtration medium and enables effective polymer flow substantially through the entire surface area of the screen without stagnation of material flow.

摘要： The present invention provides a method for producing a formed article from a dope comprising a polyphosphoric acid solvent and a polymer soluble in polyphosphoric acid, which includes using a production apparatus containing an apparatus for stirring and uniformly dispersing or homogenizing a dope and a pump apparatus for delivering the uniformly dispersed or homogeneous dope, wherein at least one of the apparatus and the pump apparatus has a part that comes into contact with the dope. According to the present invention, maintenance frequency of production facility due to the corrosion and elution of metal in a recovered solvent can be reduced, which in turn decreases the production cost.

摘要： Polyester multi-filamentary yarn, useful as tire reinforcement, is produced by melting polyester resin at 290° C. or below including at least 90 mol % of polyethylene terephthalate with intrinsic viscosity of 0.7-1.2; filtering the molten resin for filtering retention time of ten minutes or below; spinning the filtered, molten resin by extrusion through a nozzle which has 250-500 holes, each ranging in diameter from 0.5 mm to 1.2 mm with a length/diameter ratio from 2 to 5; primarily quenching the extruded yarn at a temperature of 100-195° C. in a zone of 50 mm or more distance directly below the nozzle; secondarily quenching the yarn with air at its glass transition temperature (Tg) or below; taking off the yarn at spinning stress of 0.3 g/d or greater; drawing taken-off yarn at total draw ratio of 1.3 or greater; and thermally treating the yarn at temperature 150-230° C.
