Background
In the field of fiber application, polyester fiber has become a fiber variety with the widest application and the largest consumption due to high modulus, high strength, high elasticity, good shape retention and heat resistance. However, compared with natural fibers, the traditional polyester fibers have better antibacterial and bacteriostatic properties, but due to the characteristics of chemical structures, the traditional polyester fibers still have the problems that bacteria are easy to nourish, mildew stains are generated on the surfaces of the fibers, and the fibers are even corroded.
With the development of modern technology level, people have recognized that negative ions can combine with particles with positive electricity such as floating dust, microorganisms and the like in the air, and the larger the number of negative ions in the air, the smaller the particle size of the particles is, the more easily the particles are neutralized, and the better the dust-falling and sterilizing effects are. In addition, scientific research finds that the nano-machine graphene also has a very strong killing effect on bacteria. Therefore, in recent years, attempts have been made to mix inorganic particles capable of exciting negative ions, nano-graphene and polyester fibers to prepare negative ion graphene polyester fibers so as to enhance the antibacterial and bacteriostatic properties of the polyester fibers. However, the antibacterial and bacteriostatic activity of the anion graphene polyester fiber depends on the amount of anion release from the polyester fiber and the adsorption capacity of the nanoscale graphene, and the amount of anion release and the adsorption capacity of the nanoscale graphene are influenced by the particle sizes of the inorganic particles and the graphene. Therefore, the reduction of the particle sizes of the inorganic particles and the graphene as much as possible is the key to enhance the antibacterial and bacteriostatic activity of the negative ion graphene polyester fiber.

Although the method is simple and convenient, the ceramic powder used as inorganic particles for exciting negative ions has larger particle size and less negative ion release amount, so that the antibacterial and bacteriostatic effects on the negative ion polyester fibers are not good.
