Problems solved by technology

[0003] However, the application of PET in the fiber field is limited. The reason is that the water absorption of PET is poor, and the static electricity generated after contacting or rubbing with other objects is difficult to dissipate, and it is easy to be charged with static electricity.
In the prior art, the antistatic property of PET is generally improved by mixing metal or carbon powder, but after adding metal or carbon powder, it is easy to reduce the mechanical strength of the PET material, resulting in easy fiber breakage
