Preparation and Properties Study of Super Hydrophobic-oleophylic Polypropylene Fabric
The surface of polypropylene non-woven fabric was etched by plasma technology,and then modified by hydrophobic coupling agent octyltrichlorosilane through chemical phase deposition to reduce its surface energy,and a super hydrophobic-oleophylic polypropylene fiber material was prepared.The plasma treatment process was optimized by orthogonal experiment.The morphology of polypropylene fiber after optimization was characterized by scanning electron microscope.The specific surface area,oil absorption time and recycling performance of polypropylene fiber were tested.The results show that the optimized process of plasma treatment is:vehicle speed of 5.4 m/min,discharge voltage of 24 kV,action interval of 2.4 mm,and octyltrichlorosilane mass fraction 28%.The measured static contact angle is 155.3°,the oil absorption rate is 49.30 g/g,the oil absorption saturation time is 7 s,and the oil absorption performance is still high after 10 times of oil removal and regeneration,and the oil absorption is still up to 45.90 g/g.
