Study on Hydrophilic Finishing of Polypropylene Nonwovens

He Yifan, Zhao Yaoming (South China University of Technology)  
In the paper, the principle of improving water absorbability of polypropylene spunbond nonwovens by surfactants and the demand of the selection of surfactants are discussed. After achieving the optimal conditions in hydrophilic finishing of polypropylene nonwovens by ternary component compound surfactants through the diagonal intersection law, the rule of the influence of changes of all conditions, such as finishing temperature, finishing time and consistency of the surfactants, on hydrophilicity of polypropylene spunbond nonwovens is discussed. The water-penetrating time of the finished polypropylene nonwovens is 1.2s, which proves that the excellent modified effect of hydrophilicity is achieved.
