Abstract

The invention provides a production method of bamboo charcoal polyester filament yarn. PET fondant and nanometer-stage bamboo charcoal master batch are taken as raw materials. The method comprises the following steps of: respectively transmitting and drying the two material materials, passing through an injection molding machine, extruding in a fusing way, spinning, forming in a cooling way by cross air blowing, applying oil to an oil mouth, previously stitching, discharging by a draw-off godet, stitching and forming in a coiling way, wherein the content of the nanometer-stage bamboo charcoal master batch is 23-27%. The production method of the bamboo charcoal polyester filament yarn has the following technical effects: the produced bamboo charcoal filament yarn is good in performance and stable in quality, wherein the linear density is 138dtex, the breaking strength is 2.1cN/dtex, the elongation at break is 136.8%, and the yarn unevenness is 0.8%.

Description

Technical field [0001] The present invention involves a production method of bamboo charcoal polyester filament, which belongs to the field of chemical fiber technology. Background technique [0002] With the advancement of society, people's demand for functional high -end clothing is getting greater.
