Research and Characterization of Water and Oil Repellent Finishing Auto Interior Materials
The treatment of resist water and oil by low-temperature plasma technology for recycled polyethylene terephthalate(PET)fiber automotive interior carpet was studied.The best process conditions were optimized:low-temperature plasma processing power was 150W,vacuum was 30Pa, time was 10 min,perfluorooctylsulfonyl amide(C8H2F17NO2S)monomer concentration was 15%.With angle measurement instrument,scanning electron microscopy and infrared spectroscopy,the performance of PET interior carpet on the condition of optimum process was tested and analysed.The result showed:there was cross-linked esterification between C8H2F17NO2S monomer and PET molecules,some C-F groups with low surface energy appeared on the fiber surface.Namely, C8H2F17NO2S monomer was effectively grafted onto the surface of PET fiber.The PET interior carpet had a better effect on resisting water and oil.
