The oxygen glow-discharge plasma treatment of a poly(ethylene terephthalate
) film and fabric differing in their specific surface area was studied. The
rates of mass loss, oxygen uptake, and gas evolution were measured over th
e discharge current and pressure ranges 20-110 mA and 50-200 Pa, respective
ly, at a sample temperature of 357 K. The specific etching and product form
ation rates calculated with accounting for the total surface area of fabric
samples were shown to be not affected by the texture of studied materials.
