[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] Combination Figure 1 , Figure 2 and Figure 3 , this embodiment is described in detail. The antistatic knitted sweater involved in this embodiment includes a knitted sweater body, the knitted sweater body includes a body 1 and sleeves 2 fixedly connected to both sides of the body 1. The fabrics used for the body 1 and the sleeves 2 include a composite antistatic fabric layer 11, a thermal insulation fabric layer 12 and a skin-friendly fabric layer 13. Specifically, they are composited by hot melt adhesive mesh.

[0022] The antistatic fabric layer 11 is woven from parallel-twisted antistatic polyester filaments and bamboo fiber yarns in a plain weft stitch; the antistatic polyester filaments include polyester filaments 111 , a polydopamine film layer 112 and a GO layer 113 .

[0023] GO has excellent conductive properties. After polyester filaments are loaded with GO, their conductivity accelerates the dissipation of surface charges on polyester filaments, thus making polyester fabrics antistatic. Since the polyester surface lacks active groups, it is not easy to combine with GO and needs to be modified. Dopamine can combine with each other through hydrogen bonds, π-π stacking and charge transfer under specific conditions to form stable polydopamine. The catechol structure of polydopamine and catechol self-oxidation form a polydopamine film with super strong adhesion, so dopamine is used to modify polyester filaments to load GO. On the one hand, the hydroxyl groups of polydopamine can form hydrogen bonds with the terminal hydroxyl groups of polyester to adhere to the surface of polyester filaments. On the other hand, the free hydroxyl groups in polydopamine form chemical bonds with the hydroxyl groups of GO to form a close connection. In addition, the catechol groups, amino groups, aromatic groups and other active groups of polydopamine provide a large number of active sites to make dopamine closely connected with the surface of polyester filaments and GO.

[0024] The thermal insulation fabric layer 12 is woven from thermal insulation core-spun yarn, and the thermal insulation core-spun yarn includes hollow polyester filaments and feather-like cotton raw materials wrapped on the outside of the hollow polyester filaments. The existing Chinese patent number is: 201580011595.3, the patent name is: Feather-like cotton raw material and its manufacturing method, which discloses a feather-like cotton raw material. The feather-like cotton raw material is in the shape of a long line and has cotton-like long fibers around the periphery. The feather-like cotton raw material is fluffy and has a good warming effect.

[0025] Furthermore, the skin-friendly fabric layer 13 is woven from parallel-twisted silk fiber yarns and cuprammonium fiber yarns.

[0026] Furthermore, the body 1 also includes a hem 3 arranged at the bottom; the hem 3 is woven from a first elastic antistatic core-spun yarn, and the first elastic antistatic core-spun yarn includes spandex filaments and antistatic polyester filaments coated on the outside of the spandex filaments.

[0027] Furthermore, an elastic cuff 4 is provided at the end of the sleeve 2; the elastic cuff 4 is woven from a second elastic antistatic core-spun yarn, and the second elastic antistatic core-spun yarn includes nylon filaments and antistatic polyester filaments and cotton fiber yarns wrapped around the outside of the nylon filaments.

[0028] Furthermore, the fiber used in the cotton fiber yarn is copper ion antibacterial modified cotton fiber.
