The present application relates to the technical field of textile fibers, in particular to an antibacterial polyolefin elastomer fiber and a preparation method thereof, the preparation method being: mixing and granulating antibacterial polyolefin elastomer materials to obtain spinning granules; the antibacterial polyolefin elastomer materials comprising ethylene-propylene copolymer A, maleic anhydride grafted ethylene-octene copolymer B and antibacterial agent C; the antibacterial agent C comprising hydroxyl modified nano-silver, polyhexamethylene guanidine hydrochloride and silane coupling agent; and the spinning granules being subjected to melt spinning to obtain the antibacterial polyolefin elastomer fiber. The antibacterial polyolefin elastomer fiber has broad-spectrum antibacterial property, and the fiber has good mechanical properties and elasticity, and the spinning process is smooth, being suitable for industrial application. The present application has simple process, low cost and green environmental protection, and the prepared antibacterial polyolefin elastomer fiber can be applied to various scenes such as antibacterial close-to-body textiles, medical protection, baby products and the like.

The invention discloses a polyethylene clean film, a packaging bag and a preparation method thereof, and relates to the technical field of polyethylene packaging bags, the polyethylene clean film comprises the following components by weight: 75-90 parts of low density polyethylene, 4.5-6 parts of a bacteriostatic agent, 2.5-3.6 parts of functionalized graphene oxide, and 2-3.2 parts of modified nano zinc oxide. According to the polyethylene clean film, the packaging bag and the preparation method of the polyethylene clean film, the bacteriostatic agent and the polyethylene chain interact to form hydrogen bonds or physical entanglement, so that molecular chains are combined more tightly, the tensile strength of the packaging bag is improved, and the risk of breakage is reduced; due to the addition of the bacteriostatic agent, the flexibility and the sliding property of a molecular chain are improved, energy can be dissipated through chain segment movement when the packaging bag is subjected to external force, the impact resistance and the flexibility are improved, and the possibility of embrittlement is reduced; the bacteriostatic agent can also form a barrier layer in a polyethylene matrix or disorganize a gas diffusion channel, increase the tortuosity of the gas diffusion channel and reduce the permeability of gases such as oxygen and carbon dioxide.
