Classification: CPC D | IPC D

Claim 1:
2. The method of claim 1, Wherein a method for forming the core-spun yarn comprises the following steps:
(A): mixing, and stirring the blended slurry, the nano metal solution, the inorganic particles, and the thermoplastic polyurethane colloidal particles to form a mixed material, wherein the nano metal solution comprises first metal ions and comes into contact with the blended shiny to form a first metal ion fiber comprising the first metal ions;
(B): bringing a second metal into contact with the first metal ion fiber, so that the first metal ions undergo a reduction reaction to obtain a nano copper fiber yarn, wherein the nano copper fiber yarn comprises first metal nanoparticles obtained by means of the reduction of the first metal ions;
(C): drying the mixed material to remove moisture, and performing hot-melt spinning on the mixed material in a spinning machine, to obtain yarns from an outlet of the spinning machine to form the core thread, Wherein the thermoplastic polyurethane colloidal particles are hot melted and then wrapped around the peripheral side of the core thread obtained from the outlet to form a first-stage thread;
(D): shaping a surface of the first-stage thread by performing first cooling on the first-stage thread;
(E): extending the cooled first-stage thread by using a tensile device;
(F): repeating step (A) and step (B) on the first-stage thread, and wrapping the mixed material around a periphery of the first-stage thread;
(G): shaping an inside of the first-stage thread by performing second cooling on the first-stage thread, to form a second-stage thread; and
(H): collecting the second-stage thread to form a deodorant and antibacterial nano copper fiber yarn, wherein the deodorant and antibacterial nano copper fiber yarn is the first fiber thread or the first fiber thread and the second fiber thread.
