NOVELTY - Preparing dry sanitary towel based on high-opening suction plastic net comprises (i) (i-1) mixing 60-70 pts. wt. polybutylene succinate (PBS) resin, 15-20 pts. wt. graphene composite modified starch, 18-25 pts. wt. nano inorganic filler, 0.3-0.6 pts. wt. antioxidant, 1-2 pts. wt. lubricant and 0.6-1.2 pts. wt. titanic acid ester coupling agent, (i-2) adding all the ingredients to the mixer for mixing after drying is completed, and obtaining mixture after the mixing is completed, and (i-3) placing the mixture into the extruder to melt and extrude to obtain sheet, and making rectangular sheet into plastic-absorbing net containing rhombus mesh, (2) mixing and stirring nano tourmaline powder, tourmaline powder and water, (3) bonding fine cotton yarn with warp, and (4) bonding the negative ion layer to the bottom of the blister net to form anti-wrinkle layer, and pasting pressure-sensitive adhesive tape on outside of the outer layer to obtain finished sanitary napkin. USE - The method is useful for women menstrual period, sanitary napkins, sanitary cotton strips, menstrual cups and protective pads. ADVANTAGE - The sanitary towel can absorb the menstrual blood, has fast absorption effect, can keep the female privacy part dry and ventilate, and has antibacterial, absorbing peculiar smell and better use effect. DETAILED DESCRIPTION - Preparing dry sanitary towel based on high-opening suction plastic net comprises (i) (i-1) taking 60-70 pts. wt. polybutylene succinate (PBS) resin, 15-20 pts. wt. graphene composite modified starch, 18-25 pts. wt. nano inorganic filler, 0.3-0.6 pts. wt. antioxidant, 1-2 pts. wt. lubricant and 0.6-1.2 pts. wt. titanic acid ester coupling agent, (i-2) drying the PBS resin, graphene composite modified starch, nano-inorganic filler, antioxidant, lubricant and titanic acid ester coupling agent, where the drying temperature is 70-80℃, and the drying time is 30-35 minutes, adding all the ingredients to the mixer for mixing after the drying is completed, where the mixer speed is 80-120 revolutions/minute, and the mixing time is 20-30 minutes, and obtaining the mixture after the mixing is completed, and (i-3) placing the mixture into the extruder to melt and extrude to obtain sheet, passing the sheet into thin sheet through blister machine, cutting the sheet into rectangular sheet with width of 3 cm and length of 10 cm, cutting the thin sheet into rectangular sheet with width of 3 cm and length of 10 cm, cutting the four corners of the rectangular sheet into arc angles, where the radius of the circle corresponding to the arc angle is 5 cm, punching and cutting the rectangular sheet, and making the rectangular sheet into plastic-absorbing net containing rhombus mesh, (ii) mixing and stirring nano tourmaline powder, tourmaline powder and water at mass ratio of 1:1:8 to make mixed solution, soaking the non-woven fabric in the mixed solution, where the immersion time is 10-20 minutes, taking out the non-woven fabric after the immersion is completed, and drying to obtain anion layer, (iii) bonding the fine cotton yarn with warp and weft density of 80-90 and the polyethylene (PE) film to form the outer layer, and using pure cotton spunlace non-woven fabric as the inner layer, and (iv) bonding the negative ion layer to the bottom of the blister net to form anti-wrinkle layer, washing the cotton and drying in sterile environment, carbonizing under the protection of nitrogen to obtain cotton carbon fiber, blending cotton carbon fiber and bamboo charcoal fiber, obtaining absorbent filling, laying the anti-wrinkle layer over the outer layer, laying the absorbent filling over the anti-wrinkle layer, laying the inner layer on top of the water-absorbent filling, carrying out rolling and cutting of the whole, carrying out the hemming process after the trimming is completed, and pasting pressure-sensitive adhesive tape on the outside of the outer layer to obtain finished sanitary napkin.
