摘要
Main factors affecting the low temperature plasma initia-tion and graft modification of acrylic acid onto polybuty-lene terephthalate(PBT)meltblown nonwovens are stud-ied.The relations between hydrophilic performance ofthe product and plasma power,treating time,andmonomer concentration are investigated.The surfaceperformances of grafted products are analyzed.It is ob-tained that hydrophilic performance of PBT nonwovens isgreatly improved due to the etching of the plasma andthe introduction of polar groups so as to meet the needsof leukocyte depleting materials.
