The quaternary amine cations are hydrophilic groups, extend outwards, adsorb water molecules on the surface of the terylene through the action of hydrogen bond static electricity, have stronger water absorbability, and the chloride anions can move in water to play a role of ion conduction, so that the resistance of the terylene is reduced, the antistatic capacity is improved, and the chloride ions can enter bacteria bodies to destroy bacterial metabolism, thereby achieving the aim of resisting bacteria. The carboxymethyl cellulose has a uniform porous structure, so that the carboxymethyl cellulose has higher porosity and water retention capacity, and the structure determines that the carboxymethyl cellulose has better air permeability and water retention rate. The polyester fabric prepared by the invention has excellent air permeability, water retention, antibacterial property and antistatic property.
