Abstract
Currently, textile materials with multifunctional properties have considerably attracted more and more attention in scientific community. In this work, multi-properties of polypropylene (PP) spunbond nonwoven fabric including high hydrophobicity, antibacterial, and UV protection were successfully improved by grafting of 2,2,2-Trifluoroethyl methacrylate (TFEM) and titanium dioxide (TiO2) onto the fabrics with gamma irradiation as an alternative to the conventional chemical method. Prior to grafting procedure, the TiO2 nanoparticle was primarily functionalized with maleic anhydride (MAH) to facilitate interaction between surfaces. Then, the modified TiO2 nanoparticle and TFEM were grafted onto the fabric via gamma irradiation. The physicochemical characteristics of modified TiO2 and grafted fabric were investigated. The results demonstrated that the modified TiO2 offered an excellent surface reaction between PP spunbond. Additionally, the grafted fabrics presented astoundingly high water contact angle at about 120 °, UV resistance with UPF (UV protection factor) value of 122–124, as well as an obvious occurrence of inhibition zone on antibacterial test. It was noteworthy that the grafted fabric in this work would have an attractive application as protective clothing for practically use in medical, industrial, and outdoor applications.
