I have taken SEM pictures of the surface of polyester fabric before and after Plasma treatment at magnification × 20.000, there was no difference in the morphology of the fibers, does that make sense? Or there is something wrong?
Поверхность волокна может изменится при увеличении длительности обработки, так как само сам материал неоднороден и есть участки, где окисление проходит быстрее, что даст возможность лучше понять надмолекулярную структуру волокна и уточнить модель его механических свойств. Поздравляю, у Вас есть интуиция!
The morphology would depend on the power applied, the duration, and the distance between the nozzle and the material (in the case of plasma torch). In the case of polyester with plasma torch, I obtained a slight swelling of the ends of the filaments (like the beginning of melting).
You can try to etch the thread untreated and processed in alkali. Then it will be clear if there is a chemical reaction.
