[0002] The PA 6 ultra-fine denier POY long filament refers to a semi-finished long filament made of PA 6 (polyamide fiber) as raw material. The fiber has the characteristics of extremely soft hand feeling, good draping, strong coverage and elegant luster. POY is an intermediate product in chemical fiber production and is a semi-finished product with excellent performance. It retains a high stretching potential and can be conveniently processed (such as stretch elastic DTY) to produce final products with different styles and performance.

[0003] The long filament preparation process includes melting of the PA 6 chip raw material, extrusion spinning of the melted raw material through a metering pump to a spinning part, cooling and solidification after extrusion, and finally multi-stage stretching and winding. The spinning part sprays multiple filaments. These filaments need to be arranged and bundled into one or more composite filaments after cooling and solidification to improve the strength, uniformity and subsequent processing performance of the fiber. During the initial stage of spinning operation, the sprayed filaments need to be arranged and cut off due to the incomplete stability of the equipment temperature, pressure or material flow state. In actual production, the initial stage of the yarn is arranged, cut off and plied by manual arrangement. Although the manual operation is flexible, the operation speed is low, the uniformity of the plied yarn is poor, the skill requirement of the operator is high, the efficiency is low, and the strength of the long filament is affected.
