The invention relates to bedding prepared from a polyester antibacterial masterbatch based on a one-dimensional nanometer Ag / C composite material, belonging to the technical field of high-tech functional composite materials. According to the invention, polyester resin which is prepared by blending the polyester antibacterial masterbatch in proportion is subjected to conventional pre-crystallization, drying and melt spinning successively to prepare antibacterial polyester fibers, and the antibacterial polyester fibers are woven or are blended and interwoven with cotton, hemp and other chemicalfibers to form an antibacterial fabric. The polyester antibacterial masterbatch is prepared from polyester, a one-dimensional nanometer Ag / C composite material, micro-nano inorganic powder, an auxiliary agent and the like through blending, plasticizing, mixing, extruding, drawing, cooling and granulation. According to the invention, the one-dimensional nanometer Ag / C composite material is fully and effectively dispersed, so the one-dimensional nanometer Ag / C composite material is prevented from failures due to agglomeration and allowed to maintain long-lasting antibacterial effect; and the prepared bedding fabric has the characteristics of broad-spectrum antibacterial performance, high efficiency, durability, washing resistance, excellent performance, safety to the body, no toxicity, no harm, no allergenicity, environment protection performance, etc.
