▎ 摘  要

NOVELTY - Producing strong tension sterile spun-bonded non-woven fabric comprises (1) dissolving modified polyester in chloroform, adjusting pH of the mixture to be alkaline, adding flame retardant under the conditions of a rotating speed of 150-200 revolutions/minute at 40-50℃, reacting for 5-7 hours, distilling off solvent, melting and extruding substrate, spun into a web, and hot-rolling for reinforcement to obtain a pretreated non-woven fabric, and (2) soaking pretreated non-woven fabric in ethanol under the condition of frequency of 30-40 kHz, ultrasonic treatment for 30-40 minutes, washing with deionized water, drying, soaking in dopamine solution under the condition of 25-30℃, soaking for 20-25 hours, taking out and soaking in chitosan solution, soaking for 20-30 minutes, soaking in graphene oxide dispersion for 20-30 minutes, washing with deionized water, and drying to obtain product. USE - The method is useful for producing strong tension sterile spun-bonded non-woven fabric, which is useful for medical and sanitary material, chemical industry, automobile industry, home building material, domestic decoration and medical health. ADVANTAGE - The spun-bonded non-woven fabric has antibacterial effect, at the same time, it has a certain flame retardant effect, and avoids the burning phenomenon of the non-Woven fabric when encountering Mars.
