Efficient and short-process multi-component melt spinning device

Abstract

The invention relates to an efficient and short-process multi-component melt spinning device, which belongs to the technical field of melt spinning devices. The efficient and short-process multi-component melt spinning device comprises a single-screw extruder and a double-screw extruder, wherein a first metering pump is arranged at the head of the single-screw extruder A; a booster pump is arranged at the head of the double-screw extruder B; the booster pump is connected with a second metering pump through a pipeline; the metering pumps are connected with a spinning assembly through independent pipelines respectively. The single-screw extruder A is capable of independently realizing single-component spinning, and the double-screw extruder B is capable of much uniformly blending multi-component polymers, thus avoiding degradation on the secondary hot-pressing for hot-pressed sensitive polymers caused by pre-using the double-screw extruder for blending, extruding and granulating is avoided, and realizing short-process blending spinning, and the two screw extruders can be used simultaneously to carry out composite spinning, thus realizing three independent functions; the spinning assembly can be replaced according to the component and structure requirements of formed fibres, thus expanding the use range of the device, saving machines, and decreasing the use cost.

Description

technical field [0001] The invention relates to a melt spinning equipment, in particular to a high-efficiency, short-flow process of a single-screw extruder equipped with a first metering pump and a twin-screw extruder equipped with a booster pump and a second metering pump. The multi-component melt spinning equipment belongs to the category of textile machinery equipment. Background technique [0002] The melt spinning machine is a machine that makes the fiber-forming polymer melt or gel into filaments. Its most important component is the spinning system. The general spinning system includes: chip drying, screw extruder, melting Body pipeline, spinning box, metering pump and transmission device, spinning assembly, blowing device, oiling device, spinning tunnel, spinning control system, winding panel, godet, winding head, winding control system . The high polymer slices enter the screw extruder from the hopper and are melted and pushed by the screw and sent to the spinning...

Problems solved by technology

The former is difficult to achieve the blending of two incompatible components, and the molten two components are prone to interface separation after passing through the composite spinning assembly, resulting in a decrease in the mechanical properties of the composite fiber. The latter puts multiple components into the same In an extruder, the structure of the composite fiber cannot be controlled, for example, fibers such as sheath-core structure and segmented pie structure cannot be obtained
