    摘要： Method for manufacturing polyester fibers comprising melt-extruding a polymer without increasing an intrinsic viscosity of the polymer during spinning to minimize a reduction of the intrinsic viscosity of the polymer; maintaining a low atmospheric temperature directly below a nozzle to maximize a degree of orientation of undrawn yarn; winding the polymer at 2,000 m/min or more to produce a undrawn yarn, followed by drawing the undrawn yarn through continuous three phases at low temperature. The method has advantages in that high strength and low shrinkage polyester fibers with a uniform fineness and physical properties can be manufactured at high spinning efficiency, without formation of broken filament and curved filament, by preventing formation of a vortex of cooling air with the use of eddy plates directly below a nozzle.

    摘要： A heating furnace is used in a drawing device for drawing a base material made of plastic. The base material is fed into the heating furnace, melted under heat and drawn into a plastic optical fiber. The heating furnace is divided into a pre-heating zone located upstream and a heat-melting zone located downstream in the advancing direction of the base material and of the plastic optical fiber made therefrom. The preheating zone includes a pre-heater for pre-heating the base material, while the heat-melting zone includes a melting heater for melting the base material. Both zones are controllable independently so as to give an appropriate temperature for each zone.

    摘要： A process and apparatus for producing a dimensionally stable melt blown nonwoven fibrous web. The process includes forming a multiplicity of melt blown fibers by passing a molten stream including molecules of at least one thermoplastic semi-crystalline (co)polymer through at least one orifice of a melt-blowing die, subjecting at least a portion of the melt blown fibers to a controlled in-flight heat treatment operation at a temperature below a melting temperature of the at least one thermoplastic semi-crystalline (co)polymer immediately upon exiting from the at least one orifice, and collecting at least some of the melt blown fibers subjected to the controlled in-flight heat treatment operation on a collector to form a non-woven fibrous structure. The nonwoven fibrous structure exhibits a Shrinkage less than a Shrinkage measured on an identically-prepared structure including only fibers not subjected to the controlled in-flight heat treatment operation, and generally less than 15%.

    摘要： A melt spinning apparatus includes an apparatus body, a nozzle configured to extrude melted resin in the apparatus body, and a barrel having an air discharge passage arranged around this nozzle to discharge hot air. The discharge passage includes a sloped passage and a parallel passage that extends along the nozzle. At an intersection of imaginary lines extending along the centerlines of the sloped passage, an imaginary merging section is defined. An open end of the nozzle is positioned on the downstream side of the imaginary merging section of the hot air blown diagonally forward toward a periphery of the nozzle. To manufacture a sheet of a nonwoven fabric, the melted resin is discharged from the nozzle and then the hot air swirling diagonally forward is blown toward the periphery of the nozzle. This causes the melted resin to be formed into spiral fibers. Those fibers are blown onto the belt of a conveyor belt apparatus to manufacture a nonwoven fabric sheet.
