The present invention relates to the technical field of packaging materials, and discloses an antistatic composite packaging material and a preparation process thereof, the antistatic composite packaging material comprises: a base material layer, the base material layer is made of a polyester film or a hard paperboard material, and the base material layer is used as the bottommost layer of the composite material; the metal oxide static electricity absorption layer is made of aluminum oxide or an oxidation material; the metal foil layer is made of an aluminum foil material; a polyurethane protective film is adopted as the outer layer protective film; and the surface antistatic coating is made of a polytetrafluoroethylene material. Through the multi-layer structure design, the metal oxide static electricity absorbing layer (such as aluminum oxide or titanium oxide) and the metal foil conducting layer are adopted, and the long-acting antistatic effect is provided. By means of the design, the problems that a traditional antistatic coating is prone to abrasion and the efficacy is decreased progressively are solved, it is ensured that the material can still keep stable antistatic performance after being used for a long time, and the material is especially suitable for products needing to be stored and transported for a long time.

This invention relates to the field of fabric technology, specifically to a breathable antibacterial fabric and its preparation process, and sportswear made from this fabric. The preparation process of the breathable antibacterial fabric includes: preparation of a composite antibacterial agent, preparation of multifunctional polyester fibers, amination modification of phenolic lignin, modification treatment of polyacrylonitrile, and preparation of the breathable antibacterial fabric. The breathable antibacterial fabric of this invention consists of inner, middle, and outer layers: the inner layer is a blend of modal and other materials, which is skin-friendly, moisture-wicking, and antibacterial; the middle layer is a polyurethane film layer; the outer layer contains polyacrylonitrile composite fibers, which are antibacterial, crisp, and breathable. A composite antibacterial agent made of chitosan, cysteine, and copper nitrate imparts dual antibacterial properties to the fabric, reducing bacterial resistance. Ethylene treatment enhances the bonding of components, improving wash resistance and antistatic properties; the co-spinning of amination-modified phenolic lignin and polyacrylonitrile increases fiber strength, breathability, and UV resistance. This fabric is suitable for sportswear.

The present application belongs to the field of functional materials and textile technology, and particularly relates to a multi-network biological matrix hydrogel conductive coating as well as a preparation method and application thereof.
