Zusammenfassung:	The invention provides a preparation method of a soft medical surgical gown SMS non-woven fabric. The soft medical surgical gown SMS non-woven fabric adopts the following raw material: a PP spun-bonded material, a polyolefin copolymer, an amide additive, a PP melt-blown material, special spun-bonded blue master batches and special melt-blown blue master batches in the mass ratio of 50-65: 15-25: 0-3: 18-25: 0.5-3.0: 0.5-3.0. The preparation method comprises a melt extrusion step, wherein in melt extrusion, the temperature of a screw adopted by the spun-bonded mixture is 225-235 DEG C, the temperature of a melt pipe adopted by the spun-bonded mixture is 230-235 DEG C, the temperature of a die head adopted by the spun-bonded mixture is 233-238 DEG C, the temperature of a screw adopted by themelt-blown mixture is 235-245 DEG C, the temperature of a melt pipe adopted by the melt-blown mixture is 245-255 DEG C, and the temperature of a die head adopted by the melt-blown mixture is 255-260DEG C. The preparation met
