Abstract

The invention discloses a continuous spinning set of polyester filament yarns, comprising a screw extruder. A hopper is connected to the top of the screw extruder. A spinning component is disposed below the screw extruder. A yarn chamber used for yarn cooling is disposed below the spinning component. Below the yarn chamber along a spinning path, provided in order are a first collector, a first hot roller, a second hot roller, a second collector and a winding roller, and a friction roller is disposed on the outer periphery of the winding roller. The continuous spinning set is simple in structure, reasonable in design and convenient to operate; under mutual cooperation of the screw extruder, the spinning component, the yarn chamber, the first collector, the first hot roller, the second collector and the winding roller, the process of from raw materials to spinning is achieved; operating is simple, the cost is low, and fiber strength is high; meanwhile, the yarn chamber is provided with a side blower, and spinning quality of polyester filament yarns can be improved.

Description

technical field [0001] The invention relates to the technical field of chemical fiber spinning equipment, in particular to a polyester filament continuous spinning device. Background technique [0002] The forming of chemical fibers is a process in which polymer bodies are extruded from spinneret holes at a certain flow rate and solidified to form fibers. As one of the main spinning methods of chemical fibers, dry spinning refers to the fine flow of spinning solution extruded from the capillary of the spinneret by the polymer melt into the spinning tunnel, and through the action of the hot air flow in the tunnel, The solvent in the thin stream of stock solution is quickly volatilized, and the volatilized solvent vapor is taken away by the hot air flow. The stock solution solidifies while gradually removing the solvent, and elongates and becomes thinner under the action of winding tension to form primary fibers. The traditional dry spinning device has complex structure, cumb...
