The Dependence of Strength Characteristics of Synthetic Fibers on the Composition of Plasma-Forming Gas and Treatment Time When Exposed to a Low-Pressure Discharge

The physics of modifying the mechanical properties of synthetic fibers during treatment in a capacitive coupling plasma (ССP) discharge at reduced pressure is considered. The dependence of the tensile strength limit of various types of fibers on the composition of the plasma-forming gas, as well as on the duration of the treatment, has been determined. It was found that a mixture of argon and propane-butane allows for the greatest increase in tensile strength for all types of synthetic fibers studied.
