How much improved the surface wettability of PET polyester fiber treated by the online plasma processor:
Polyester fiber is also called PET fiber, which is commonly referred to as polyester fiber material. The surface of PET polyester fiber material is usually hydrophobic and has poor wettability, so it is often used for surface modification by online plasma treatment machines. Let's take a look at what practical effects will be produced when the online plasma processor processes polyester fibers?
A contact angle tester was used to test the actual treatment effect of the online plasma processor. The results showed that: as the actual treatment time of the plasma cleaner gradually increased, the contact angle of the PET fiber surface was significantly reduced, and the surface wettability and hydrophilicity It has also improved. After reaching a certain treatment effect, continue to increase the treatment time. The actual improvement effect is slowly improved, or even remains unchanged. Therefore, when processing actual PET fiber materials, it is recommended to select an appropriate processing time through experiments.

By using oxygen as the process gas to treat PET fiber, the online plasma processor can introduce oxygen or nitrogen polar groups on the surface of the PET fiber, increase the oxygen and nitrogen content on the surface of the fiber, and reduce the surface carbon content, thereby improving the PET fiber Surface wettability and hydrophilicity.
