It can be seen from Tab.2 that G was increased firstly and then decreased with the increase of crosslinker concentration and was maximized as 48.8%at the crosslinker mass fraction of 2.0%;and the gelation made the macromolecular radical termination diminished and thus promoted the grafting.However,the over-loaded crosslinker usually produces the dense polymer networks,which hinders the monomer diffusion onto the fabric surface and reduces grafting[5].
