Abstract

PURPOSE: To obtain modified synthetic fibers by the efficient kneading without degrading the quality thereof, by extrudng a high-melting thermoplastic polymer and a low-viscosity organic modifier through a mixing and extruding spinning machine having a screw equipped with pins in a direction at a right angle to the shaft on the outer periphery of the tip.
CONSTITUTION: A high-melting thermoplastic polymer 2, e.g. polyethylene terephthalate and a low-viscosity organic modifier 8 are melt mixed and extruded through a screw type mixing and extruding spinning machine. In the process, a screw 3 having a tip part without a flight 11 and 1W3 rows of cylinders 13 having almost the same height as that of the flight 11 in a directon at a right angle to the shaft is used. The polymer 2 is fed from a hopper 1, sent to the direction of a toe 4 by the rotation of the screw 3 and molten to a metering part 6 by the compression, shearing and heating between the screw 3 and a barrel 5. The modifier 8 is forced from an introductory inlet 7, kneaded with the polymer 2, passed through a plate 9 and the toe 4 and then spun through an extruding outlet 10.
