| Abstract: | Polyethylene terephthalate (PET) and polyethylene (PE) fibers were surface photo - grafted with acrylic acid (AA) by using UV irradiation photochemical initiation during a continuous winding process within 1-2 minutes. The grafted fibers were characterized by measurements of dye uptaking, moisture regain, pull - out forces of monofilament from cured matrix, as well as by analysis of ESCA and ATR - FTIR spectra. All these results confirm that the surface behavior of the UV - irradiation grafted fibers was greatly improved. It was also proved that the original excellent mechanical properties of the fibers were well - retained after the surface grafting treatment. |
