Study of Irradiation Hydrophilic Modification of Polypropylene Meltblown Nonwovens

Article Preview

Abstract:

In this paper, we took the co-irradiation technology, use the high-energy beam irradiate the polypropylene meltblown nonwovens which soaked with acrylic acid, so that the graft copolymerization reaction was occurred between the acrylic and the polypropylene, the influence of acrylic acid concentration and the irradiation dose to the hydrophilic properties and breaking strength were studied. The results shows that when the monomer concentration was between 2% and 8% and the irradiation dose was between 10kGy and 50 kGy, the hydrophilic properties increased with the increasing of the monomer concentration and irradiation dose. But the breaking strength wasn’t affected.
