Abstract

The invention discloses an FDY filament spinning and pulling machine, which comprises an extrusion device, a melt piping system, a metering pump, a spinning device, a cooling device, a tunnel part, an oiling device, and a wire guide device arranged in sequence according to the production process. The cooling device includes an annealing unit, a monomer suction unit and a side air cooling unit. The annealing unit is connected between the spinning unit and the side air cooling unit, and is located at the outlet of the spinning unit Wire end; the slow cooling device includes a delay cooling air chamber and a slow cooling heater, and the slow cooling heater heats the delay cooling air chamber; the single suction part is connected to the wire inlet end of the side blowing cooling part; the wire outlet of the side blowing cooling part The end communicates with the passage part. By setting the monomer suction device and using high-pressure water jet to suck the monomer, it overcomes the defect that the monomer crystal adheres to the spinneret and the side air outlet hole in the existing device, which causes the deterioration of spinning conditions and the increase of broken ends. , shorten the production cycle and improve the spinning quality.

Description

technical field [0001] The application belongs to the technical field of spinning machinery and equipment, and in particular relates to an FDY filament spinning and drawing combination machine. Background technique [0002] FDY (FULLY DRAWN YARN), introducing stretching in the spinning process, can obtain winding yarn with high degree of orientation and medium crystallinity, so it is also called fully drawn yarn. The conventional fully drawn yarns of polyester (polyester fiber) and nylon (also known as nylon, polyamide) are chemical fiber filaments. FDY fabric feels smooth and soft, and is often used to weave imitation silk fabrics, and has a wide range of uses in clothing and home textiles. [0003] The wear resistance of nylon fabric ranks first among all kinds of fabrics, and is many times higher than other fabrics of similar products. Therefore, its durability is excellent. It is not only the best choice for down jackets and mountaineering clothes, but also often blende...
