Problems solved by technology

[0002] Microfiber is a fiber with a diameter less than 5 microns, and its spinning difficulty is relatively high. The existing melt spinning device room adopts the melting method of hot air drafting for spinning. Its energy consumption is high, and because of the high temperature (above 200°C) hot air drafting, it is difficult to eliminate the thermal stress inside the fiber, so the softness of the produced fiber is poor, and the tensile strength of the fiber is low

Abstract

The invention discloses a throat-tube type cold-wind-drafted and melt micro-fibre spinning device. The throat-tube type cold-wind-drafted and melt micro-fibre spinning device specifically comprises an extruder, a metering pump, a spinneret plate, a throat-tube type airflow drafter, a receiving device and a winding device, wherein the extruder penetrates through the metering pump through a conveying tube and is connected with the spinneret plate; the spinneret plate is arranged at the upper end of the throat-tube type airflow drafter; a spinneret is arranged at the lower end of the spinneret plate; the throat-tube type airflow drafter comprises an upper portion and a lower portion; a first airflow channel is formed between the upper portion and the lower portion; the centre of the lower portion is a second airflow channel; the receiving device is arranged just below the second airflow channel; the winding device is located at one side of the receiving device. According to the throat-tube type cold-wind-drafted and melt micro-fibre spinning device disclosed by the invention, production energy consumption is greatly reduced, energy is saved, and carbon emission is reduced.

Description

technical field [0001] The invention relates to a spinning device, in particular to a throat-type cold air drafting molten microfiber spinning device. Background technique [0002] Microfiber is a fiber with a diameter less than 5 microns, and its spinning difficulty is relatively high. The existing melt spinning device room adopts the melting method of hot air drafting for spinning. Its energy consumption is high, and because of the high temperature (above 200 ℃) hot air drafting, it is difficult to eliminate the thermal stress inside the fiber, so the softness of the produced fiber is poor, and the tensile strength of the fiber is low. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a brand-new drafting principle, to provide a melted microfiber spinning device that adopts cold air drafting, and through a throat-type air drafter with a special structure, the molten microfiber that flows out The resin passes ...
