T. Wakida et al., SURFACE CHARACTERISTICS OF WOOL AND POLY(ETHYLENE-TEREPHTHALATE) FABRICS AND FILM TREATED WITH LOW-TEMPERATURE PLASMA UNDER ATMOSPHERIC-PRESSURE, Textile research journal, 63(8), 1993, pp. 433-438
Wool and poly(ethylene terephthalate) fabrics and film were treated wi
th low-temperature plasmas of helium/argon or acetone/argon under atmo
spheric pressure for 10 to 180 seconds. Although argon itself cannot i
ndependently generate a plasma under atmospheric pressure by applying
high frequency voltage, it is easily generated by adding a small quant
ity of helium or acetone to argon gas. Wettability of the fabrics and
surface tension of the film increased considerably with the treatment
within 30 seconds. ESCA analysis was used to elucidate the surface che
mical composition of fibers treated with atmospheric low-temperature p
lasma. Relative O1s intensity increased considerably and oxygen was in
corporated in the form of -CO- and -COO- on the fiber surface. From th
ese results, it appears that low-temperature plasma by atmospheric pre
ssure discharge is effective for modifying the polymer surface, as it
acts in the same fashion as low-temperature plasma by glow discharge.
