▎ 摘  要

NOVELTY - Preparation method of degradable environment-friendly non-woven fabric, which involves: i. mixing polypropylene, nano silver ions, n-butanol, polyvinylpyrrolidone, and ethoxylated alkyl acid amine uniformly, adding nano silver ions and mixing again, heating to 60-80 degreesC, holding for 1-3 hours, adding it in a high-speed mixer, stirring at 500-900 revolutions per minute (r/min) for 1-3 hours, after cooling to room temperature, the base material is obtained; ii. heating the base material to 45-58 degreesC, during the heating process, adding plant fiber, collagen fiber, calcium carbonate, corn starch, inorganic germanium powder and mixing evenly, and then heating to 65-75 degreesC, keep warming after reaching the rated temperature, stirring continuously during the heat preservation process; iii. in the product obtained in step S2, mixing and adding penetrant, elastomers and gelatin and then stirting and mixing and keep warm for 2-4 hours. USE - Preparation method of degradable environment-friendly non-woven fabric ADVANTAGE - Preparation method of degradable environment-friendly non-woven fabric effectively improves the antibacterial and mildew-resistant performance of the non-woven fabric produced subsequently, also realize the complete explanation of the whole non-woven fabric body, play a role in soil fertility improvement, and improve the tensile property of the non-woven fabric product to a certain extent by adjusting the degradation time of the product with calcium carbonate, so that the product is tougher and the product quality is improved. DETAILED DESCRIPTION - Preparation method of degradable environment-friendly non-woven fabric, which involves: i. mixing polypropylene, nano silver ions, n-butanol, polyvinylpyrrolidone, and ethoxylated alkyl acid amine uniformly, adding nano silver ions and mixing again, heating to 60-80 degreesC, holding for 1-3 hours, adding it in a high-speed mixer, stirring at 500-900 revolutions per minute (r/min) for 1-3 hours, after cooling to room temperature, the base material is obtained; ii. heating the base material to 45-58 degreesC, during the heating process, adding plant fiber, collagen fiber, calcium carbonate, corn starch, inorganic germanium powder and mixing evenly, and then heating to 65-75 degreesC, keep warming after reaching the rated temperature, stirring continuously during the heat preservation process; iii. in the product obtained in step S2, mixing and adding penetrant, elastomers and gelatin and then stirting and mixing and keep warm for 2-4 hours; iv. adding silane coupling agent KH-570 (methacryl-functional silane) to step S3 and mixing evenly, continue to heat up to 80-90 degreesC, adding it in a high-speed mixer at 700-900 r/min and stir and dispersing for 1-5 minutes, modified material is prepared; v. after the modified material prepared in step S4 is melted, it is mixed with copper oxide and graphene, and the molten fluid is obtained after mixing and the molten fluid is evenly extruded from the extruder, extruded fluid is taken out through the filter to remove impurities and carrying out further mixing, and then enter the spinning system; vi. consolidating the molten fluid into filaments by a spinning system, evenly spreading on the conveyor net, lay the wire into a net, after hot rolling into the web, it enters the rolling mill for coiling, and then is cutting by the slitting machine, and the non-woven fabric is obtained after drying.
