Effects of the Polypropylene Fabric Morphology on the Photografting Copolymerization of Methacrylics
The effect of the polypropylene fabric morphology on the grafting copolymerization of methacrylics in the aqueous solution under ultraviolet irradiation was investigated.The infrared spectra and the scanning electron microscopy images verified the successful grafting copolymerization of the two monomers, glycidyl methacrylate (GMA) and Hydroxyethyl methacrylate (HEMA), onto the three fabrics, the spunbonded polypropylene nonwovens (SB), the spunlaid-meltblown-spunlaid polypropylene nonwovens (SMS), and the polypropylene monofilament plain fabrics (MPF).The results showed that, the grafting degrees of the two monomers increase and then tend constant with irradiation time, while those increase with the increase of the monomer concentrations for all the fabrics.The tight texture structure and the well-stretched monofilament surfaces of the MPF fabrics retard the grafting to a great extent.The inner fluffy meltblown layer of SMS nonwovens favors the grafting as compared with the SB nonwovens.
