NOVELTY - Preparing colorful anti-bacterial socks with good yarn comprises: (i) preparing carbon material of copper powder with copper salts and carbon nanotubes or graphene as raw material by copper salt precipitation method; (ii) pretreating by pre-crystallizing silicone polyester chips, carrying out solid-phase polymerization, charging into a reactor and adding carbon material of copper powder and the silicone polyether silicone oil, stirring to obtain a polymer melt; (iii) spinning; and (iv) dyeing of yarn to obtain the product. USE - The method is useful for preparing colorful anti-bacterial socks with good yarn (claimed). DETAILED DESCRIPTION - Preparing colorful anti-bacterial socks with good yarn comprises: (i) preparing carbon material of copper powder with copper salts and carbon nanotubes or graphene as raw material by copper salt precipitation method; (ii) pretreating by pre-crystallizing silicone polyester chips, carrying out solid-phase polymerization, charging into a reactor and adding carbon material of copper powder and the silicone polyether silicone oil, stirring to obtain a polymer melt; (iii) spinning of polymer melt with digitally controlling of twin-screw extruder for quantitative feeding, spinning, stretching and post-treatment to obtain yarn; and (iv) dyeing of yarn to obtain the product.
