Embodiment 1
[0027] A method for preparing a hydrophilic antibacterial nonwoven fabric, comprising the steps of:
[0028] S1. Put 10kg of bamboo powder into the calciner, calcinate at 500°C for 20min under the protection of nitrogen, cool down to room temperature, pulverize, add 6kg of ethylene glycol and methacrylic acid block copolymer, 0.5kg of azobisisobutyronitrile, 80kg Ethanol, reflux at 80°C for 2h, the stirring speed is 500r / min, filter, the product is washed with ethanol and water successively, vacuum dried, and pulverized to obtain hydrophilic antibacterial bamboo powder;
[0029] S2. Add 16kg of graphene oxide, 4kg of microcrystalline cellulose, 3kg of glucose, and 40kg of water into the autoclave, stir evenly, conduct a hydrothermal reaction at 300°C for 10 hours, naturally cool to room temperature, filter, dry at 80°C, and pulverize to obtain hydrophilic enhancement agent;
