Claim 0:
1. A manufacturing method of a deodorant and antibacterial copper nanofiber yarn, steps of the method comprising:
(A) providing a raw material, comprising a polyblend slurry, a nano-metal solution, a plurality of inorganic particles, and a plurality of thermoplastic polyurethane (TPU) rubber particles, the polyblend slurry comprising a first fiber yarn slurry and a second fiber yarn slurry, the nano-metal solution containing a first metal ion wherein the first metal ion is a copper ion;
(B) stirring the raw material into a mixed material, and making the nano-metal solution contact the polyblend slurry to form a first metal ion fiber containing the first metal ion;
(C) making second metal contact the first metal ion fiber to cause the first metal ion to undergo a reduction reaction to obtain a first metal nanoparticle, the copper nanofiber yarn containing the first metal nanoparticle obtained by reducing the first metal ion;
(D) drying the mixed material to remove moisture;
(E) performing hot-melt spinning on the mixed material in a spinning machine to spin a yarn from an outlet of the spinning machine to form a primary wire, the plurality of TPU rubber particles, after being hot-melted, being further coated on an outer peripheral side of the primary wire spun from the outlet to form a first-phase wire;
(F) forcibly cooling the first-phase wire to perform a first cooling on the wire to shape a surface of the first-phase wire;
(G) stretching the cooled first-phase wire through a stretching apparatus for stretching;
(H) cooling the first-phase wire to perform a second cooling on the wire to shape an inside of the first-phase wire to form a second-phase wire; and
(I) collecting the second-phase wire to make the wire into a finished deodorant and antibacterial copper nanofiber yarn.
