摘要： PURPOSE: To obtain a yarn having excellent flexibility and feeling, without causing the welding of the filaments, by blasting a multifilament extruded from a spinning nozzle with cooling air blasted from an air nozzle at a specific position, with a specific flow rate and a specific angle.
CONSTITUTION: In the production of a multifilament by the melt-spinning of a thermoplastic resin, the molten resin is extruded through the multi-hole spinning nozzle block 2 attached to the bottom of the main body 1 of a die, and the obtained undrawn multifilament is cooled by blasting cooling air from the air nozzle 7 separated from the multifilament 3 by ≥20mm at a flow rate of 5W20m/sec and an angle deviated from horizontal plane by ≤45°. The cooling position of the multifilament is within 0W100mm fro the nozzle face. The yarn 3 is taken up with the guide 8 and the rollers 9, 10, supplied to one or multi- stage drawing stand 12 supplied with hot air from the hot-air supplying pipe 13, and drawn at a rate of 5W600m/min to obtain the objective fiber 23.

摘要： PURPOSE: To produce a group of filaments for drawing, free from the mutual welding of the filaments and the internal strain of the filament caused by cooling, by blasting cooling air against the molten and extruded filament group at specific position, direction and flow rate.
CONSTITUTION: A filament group molten and extruded through the spinning nozzle 2 is blasted with cooling air at a point downstream of the nozzle face within 50mm from the face. The air is blasted through an air nozzle 3 placed at a point separated from the filament group by ≥20mm. The temperature of the cooling air is lower than the melting point of the resin, the direction of air flow is deviated vertically by ≤45° from the horizontal direction, and the flow rate of the air is ≥5m/sec. The frost line of each filament 4 is controlled to ≤200mm from the face of the nozzle 2.

摘要： PURPOSE:To coat a metallic corrugated pipe with a resin with uniform film thickness, by a method wherein a specified let-out capstan is used, and the ratio of the speed of a take-up capstan to that of the let-out capstan is set to be a predetermined value. CONSTITUTION:The let-out capstan 3 provided with elastic rolls 2 formed from an elastic material such as natural rubber, SBR or polyurethane and having a semicircular cross section conforming to the outside diameter of the corrugated pipe 1 is used. Namely, the metallic corrugated pipe 1 is fed toward a coating die 4 by the elastic rolls 2 provided in the let-out capstan 3, is coated with a melted thermoplastic resin supplied through a hopper 5, the thus coated pipe is cooled in a cooling tank 7, and is wound around a take-up drum 9 by the take- up capstan 8. In the above mechanism, the ratio of the speed of the take-up capstan 8 to that of the let-out capstan 3 (take-up speed/let-out speed) is set to be 1-1.18.
