In order to solve the problem that polyester nonwoven are not antibacterial and hydrophilic as medical and health products. The antibacterial and hydrophilic effects of chitosan/graphene oxide on polyester nonwoven fabrics were investigated. Chitosan and graphene oxide were prepared on polyester nonwoven fabrics by layer by layer self-assembly technology using electrostatic adsorption. The K/S value, antibacterial property, moisture regain and tensile property of the polyester nonwoven fabrics were tested. It is found that the assembly state of chitosan and graphene oxide on the surface of nonwoven fabrics can be qualitatively analyzed by investigating the K/S value; the concentration of chitosan is 3 g/mL for finishing; the finished polyester nonwoven fabrics have good antibacterial and hydrophilic properties, and the breaking strength also slightly increases. Through this study, it can be seen that chitosan / graphene oxide can be used to finish polyester nonwoven fabrics with excellent antibacterial and hydrophilic properties by layer by layer self-assembly technology.
