Space-variant yarn production equipment

The utility model provides an air-jet texturing yarn production device. The air-jet texturing yarn production device comprises an input roller, a drawing roller, an air-jet texturing nozzle and a winding device which are arranged in the advancing direction of filaments. According to the technical scheme, the filaments are synchronously subjected to heat treatment when the filaments are drawn, so that the filaments are subjected to heat treatment more uniformly, the crystallinity of all parts of the filaments is uniformly reduced, the tension of the filaments is more uniform and stable, and the quality of the filaments is improved. The strength and ductility of the filament are improved, the elongation at break of the filament is greatly improved, the draft multiple of the filament is improved, broken filaments are reduced, the filament is smooth and fine, the elongation at break of the air-jet textured yarn produced through spinning is further improved, and the air-jet textured yarn becomes softer and more fl
