Abstract

The invention relates to a chemical fiber isothermal die, which is provided with a fiber spraying device, a metering pump and a medium heat-conductive heating system, wherein the fiber spraying device is arranged at the center of the bottom of the die, and the metering pump is arranged on the upper portion of the fiber spraying device. The medium heat-conductive heating system comprises a storage box used for containing heating media and covered outside the periphery of fiber spraying device and the metering pump, heating tubes are arranged in the storage box, and a heat insulation layer is wrapped outside the medium heat-conductive heating system. The heating system outside the die heats in a conducting manner by means of external media, the temperature of the heating media in the storage box rises after the heating media is heated by the heating tubes, and the temperature in each portion of the storage box is uniform due to heat transmission, so that uniform heating is realized. Further, by the aid of the additional heat insulation layer, the values of temperature of different portions of the die are equal, and accordingly, the diameters of fibers sprayed by the fiber spraying device are equal and production quality is guaranteed.

Description

technical field [0001] The invention relates to an isothermal die head for chemical fiber filaments. Background technique [0002] Because the traditional chemical fiber filament die head adopts cast aluminum heater, quartz heater or resistance wire heater, the distribution of the heating filament is not very uniform, so the temperature difference of each part of the mold is very large, so that the filament ejected from the spinning device The wire diameters vary greatly. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiency that the temperature values ​​of various parts of the die are different, the present invention provides an isothermal die for chemical fiber filaments. [0004] The technical solution adopted by the present invention to solve the technical problem is: an isothermal die head for chemical fiber filaments, which has a spinning device located at the center of the bottom of th...
