preparation example Construction

[0022] A preparation method of antibacterial polyester fiber, comprising the steps:

[0023] (1) Preparation of antibacterial polyester masterbatch: anti-nano-scale titanium dioxide and nano-scale copper oxide are mixed in a weight ratio of 3:2 to obtain a powder mixture, and then the powder mixture and fiber-forming polymer are mixed in a weight ratio of 20-35 : The ratio of 65-80 is blended;

[0024] (2) Stir and mix the polyester chips and the antibacterial polyester masterbatch evenly at 60-80 °C;

[0025] (3) adding the mixture obtained in step (2) into a twin-screw extruder, extruding, cooling into strips, and dicing to obtain full granulation of antibacterial polyester fibers;

[0026] (4) The antibacterial PET as the skin layer obtained in the step (3) is fully granulated and the carbon fiber chips as the core layer are respectively dried, and then melted by two screw extruders respectively, and then transported to the skin by a metering pump. - Core composite spinni...
