A low-temperature plasma composite technique is used to study the hydrophilicity of PP fabric.Firstly, the plasma of gas (N2, O2, NH3) is used for the pretreatment of PP fabric to produce reactive functional groups, then, the produced reactive functional groups on the PP surface are used to graft some alcohol compounds (sorbitol, maltose, polyvinyl alcohol) in the presence of bridging agent in order to make PP fabric hydrophilic.
