A chemical fiber spinning and texturing system

Abstract

The invention belongs to the technical field of chemical fiber spinning, and in particular relates to a chemical fiber spinning and texturing system, which includes sequentially arranged yarn feeding devices for placing raw silk threads and unwinding them; a heating device for heating the unrolled silk threads ; The cooling device cools the high-temperature silk; the false twister performs false twist on the silk; the oiling device lubricates the silk; the winding device rewinds the oiled silk; It includes a degreasing device, which is arranged behind the oiling device, and absorbs excess oil on the silk by means of negative pressure adsorption. The present invention uses negative pressure adsorption to remove oil. After the oiled silk thread passes above the capillary branch tube, under the action of a negative pressure pump, the port of the capillary branch tube generates a certain suction force, which can effectively Suction the excess oil on the thread, and make the oil flow from the capillary branch pipe to the main pipe, and then flow into the liquid storage tank, which not only has high oil removal efficiency, but also will not scratch the thread.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber spinning, and in particular relates to a chemical fiber spinning texturing system. Background technique [0002] Texturing machine is a kind of textile machine that can process polyester, polypropylene and other untwisted yarns into elastic yarns with medium-strength and low elastic properties through false twist deformation. [0003] The Chinese invention patent application whose publication number is CN103572439A discloses a texturing machine, which includes a beam, an intermediate bracket, an oil storage tank, and a bobbin rack, and a heating box is set up between the intermediate brackets of the beam, and a longitudinal setting is arranged inside the intermediate bracket. There is a cooling device, a false twister is installed under the cooling device, an oil storage tank is installed under the middle bracket, an oil inlet pipe is arranged on one side of the oil storage tank, an electri...

AI Technical Summary

Problems solved by technology

However, there are also certain defects in the invasive oiling device, which limits its development: after the silk thread of the immersing oiling device leaves the oil, certain oil droplets (excessive oil) are often entrained on its surface. The conventional practice in the art is to use a scraper to scrape off excess oil

However, this method uses contact scraping, which will cause certain damage to the silk thread while scraping off the oil, especially for long-staple silk threads.
