Abstract
the purpose of surface modifications of polypropylene meltblown(PPMB) nonwovens, PPMB nonwovens were treated in the plasma system by oxygen atmosphere with different treatment time and discharge power. Dimensional change and physical properties of the treated nonwovens were evaluated. Contact angles onto PPMB nonwovens about water and methyleneiodide were measured and surface energies were calculated by Owen's method. As the results, microcraters were observed on the surface of treated nonwovens. Tenacity and breaking strain of PPMB nonwovens decreased with increasing treatment time and discharge power. Surface energy of PPMB nonwovens increased by plasma treatment. Meanwhile, the friction static voltage and dyeability of PPMB nonwovens have enhanced to some extent by oxygen plasma treatment due to the improvement of surface hydrophilicity.
