摘　　要：亚麻油经过一系列改性后与四氟丙醇反应,得到含氟酯类拒水剂,然后将其溶于乙酸乙酯中,并应用于棉织物拒水整理。通过测试整理棉织物的接触角、水滴消失时间、白度以及断裂强度,评价拒水剂的性能,得到适合的整理工艺条件为:二浸二轧拒水剂(80 g/L)→预烘(100℃,4 min)→焙烘(180℃,3 min)。经过整理的棉织物接触角达到141°,水滴消失时间为6480 s;20次水洗后,接触角仍保持在137°左右,耐皂洗效果较好。A fluorine-contained ester is prepared by the reaction of modified flax soil and 2,2,3,3-tetrafluoropropanol, and then it is dissolved in ethyl acetate and applied to water repellent finish of cotton fabric. The property of the agent is evaluated by testing the contact angle, whiteness and breaking strength of the treated fabric. The optimum finish conditions are determined as follows： double dip-double nip （ the concentration of water repellent agent is 80 g/L）→predrying （ 100 ℃ ,4 rain ） →curing （ 180 ℃, 3 min）. The contact angel of the treated cotton fabric reaches 14]°and the time of disappearance of water drop is 6 480 s. The treated fabric features fast water repellent effect to soaping and its contact angel remains 137°after 20 cycles of washing.
