▎ 摘　　要

NOVELTY - Preparing antibacterial deodorant yarn, comprises (i) melting and stirring the polyester raw materials through a furnace to obtain a polyester melt; (ii) obtaining the metal antibacterial ions through oxidation reaction under strong acid conditions, adding the liquid containing the metal antibacterial ions into the polyester melt, stirring and mixing to obtain the antibacterial polyester melt; (iii) adding the antibacterial polyester melt into the spinning device and squeezing by the metering pump in the spinning box, spraying the antibacterial polyester melt from the spinneret to form a thin stream, and cooling by a cooling device to obtain a yarn; and (iv) oiling yarn, heat-stretching and winding. USE - The antibacterial deodorant yarn is useful for fabric (claimed). ADVANTAGE - The yarn can maintain the long-lasting antibacterial and deodorant function, even after multiple washings, the metal antibacterial ions with antibacterial effect will not be completely cleaned and removed and has good air permeability and skin affinity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a composite antibacterial deodorant fabric. DESCRIPTION OF DRAWING(S) - The drawing shows a structure diagram of the composite antibacterial deodorant fabric.
