In some examples, in one of the steps, the raw materials for preparing the intermediate layer nonwoven fabric include: firstly, uniformly mixing polyethylene, polypropylene and a styrene-ethylene-butylene-styrene segmented copolymer, such as melt extrusion, and then adding a mixture of nano silver particles, sodium polystyrene sulfonate and polyaniline, and uniformly mixing again, namely, the nano silver particles, the sodium polystyrene sulfonate and the polyaniline are also mixed in advance, so that the nano silver particles, the sodium polystyrene sulfonate and the polyaniline can be initially combined under the action of electronic attraction, and then dispersed, such as melt dispersion, into other resin compositions, so that the nano silver particles are convenient to contact with the sodium polystyrene sulfonate and the polyaniline to better exert the antibacterial effect of the nano silver particles, the nano silver particles are firmly combined in the fiber, and the potential safety hazard caused by easy separation of nano silver from non-woven fabrics is avoided.
In some examples, in the second step, the preparing the raw materials of the first surface layer nonwoven fabric and the second surface layer nonwoven fabric includes: uniformly mixing sodium methylcellulose and nano silver particles, and uniformly mixing the obtained mixture with polyethylene, polypropylene and ethylene-propylene copolymer. By adopting the steps, the dispersion of the nano silver particles can be promoted, and meanwhile, the nano silver particles are firmly combined in the fiber, so that potential safety hazards caused by the fact that the nano silver is easily separated from the non-woven fabric are avoided.
In some examples, in the second step, the first surface layer non-woven fabric is pre-cooled before the intermediate layer non-woven fabric is melt-sprayed on the first surface layer non-woven fabric, and the first surface layer non-woven fabric is not fully cooled, so that the first surface layer non-woven fabric is slightly shaped, and maintains a partially melted state, so that the first surface layer non-woven fabric and the intermediate layer non-woven fabric are conveniently melt-bonded. Similarly, the intermediate layer non-woven fabric is precooled before the second surface layer non-woven fabric is fused and sprayed on the intermediate layer non-woven fabric, and the intermediate layer non-woven fabric is not completely cooled, so that the second surface layer non-woven fabric and the intermediate layer non-woven fabric are fused and bonded conveniently.

From the above, the oversleeve material obtained by the embodiment of the invention has the antibacterial rate of more than 98% on staphylococcus aureus, candida albicans and escherichia coli, and has good antibacterial effect; the water repellency and the barrier property are good, and the use safety of the surgical bag can be improved; and has better mechanical property. The amount of polyaniline in the middle layer of comparative example 1 was small, resulting in a decrease in antibacterial efficiency, indicating that the antibacterial effect of the oversleeve material can be improved by using a proper amount of polyaniline. The middle layer of the comparative example 2 adopts common ethoxylated alkyl sodium sulfate dispersant to replace sodium polystyrene sulfonate, the middle layer of the comparative example 3 adopts dodecyl diphenyl ether disulfonate as the dispersant, and simultaneously adopts higher consumption of polyaniline, but the antibacterial rate is still reduced, which indicates that the antibacterial effect of the oversleeve material can be improved by the cooperation of sodium polystyrene sulfonate and polyaniline. In comparative example 4, the amount of nano silver is relatively large, the antibacterial performance is not obviously improved, and the barrier property of the material is slightly reduced due to the influence of nano filler on the surface roughness of the fiber. In comparative example 5, polyaniline having a large content of reducing units was used, and the antibacterial efficiency of the obtained material was not improved.
