摘　　要：以超临界二氧化碳为介质,采用固态含氟树脂对涤纶织物进行疏水改性。探讨了超临界CO2处理温度、压力和时间对涤纶织物疏水性的影响。结果表明,以超临界二氧化碳为介质对涤纶织物进行疏水改性是可行的。在温度70℃、压力30 MPa条件下处理4 h,涤纶织物的疏水性可达到超疏水标准。Taking supercritical carbon dioxide as medium,polyester fabrics was hydrophobically modified with fluorine-contained resin.The influences of treating temperature,pressure and time to hydrophobicity were discussed.The results showed that hydrophobic modification of polyester fabric in supercritical carbon dioxide was feasible.The hydrophobicity of polyester fiber can reached the level of super-hydrophobic under the optimal modification conditions of 70 ℃,30 MPa and 4 h.
