POLYAMIDE STAPLE FIBER'S NOZZLE APPARATUS

摘要

This invention relates to a nozzle device that introduces prepolymer and polymerization promotion solvent from separate inlets to complete polymerization in a pipe in the course of being extruded together for a filament with molecular orientation. The device consists of a T- shaped pipe (1) for the prepolymer and a supply pipe (2) that passes through the head tube of the T-pipe (1) and supplies the polymerization promotion solvent. The gap between the two pipes is sealed at both ends of the T-head (1) and the wall of the pipe (2) within the pipe (1) is provided with at least one spray hole (3) of less than 0.23 square cm to receive the prepolymer via the holes (3) and complete polymerization in extrusion for filament.
