采用氟碳拒水拒油整理剂对高湿羊毛织物进行轧-烘-焙整理。采用常规型和纳米型三种整理剂对织物的表面化学组成、拒水拒油性能、折皱回复角和耐反复洗涤性能进行了比较。由ESCA和C1 s曲线拟合得到的表面化学组成表明，整理后的羊毛织物经多次洗涤后，常规整理剂容易脱落。纳米整理剂的氟烷基在反复洗涤后，从织物表面转向纤维内部。常规型整理剂整理后的羊毛织物拒水性能随整理条件的变化而变化不大，但随着洗涤次数的增加拒水性能急剧下降。然而，当用纳米型试剂处理时，这些值随着浓度和固化温度而增加，并且在20次洗涤后保持不变。经纳米整理剂处理后的羊毛织物，无论在何种处理条件下，都具有很好的拒油性。经纳米整理剂整理的羊毛织物的折皱回复值高于常规整理剂整理的羊毛织物，且经20次洗涤后织物的折皱回复值基本不变。
Wool fabric having high moisture content were treated with fluorocarbon-based water and oil repellent finishing agents by pad-dry-cure system. Three types of finishing agents which were regular-type or nano-type were adapted to compare the surface chemical composition, water and oil repellent property, crease recovery angle, and durability to repeated laundering. From the surface chemical compositions resulted by ESCA and C1s curve-fitting, it was shown that the regular-type finishing agent were easily taken off from the finished wool fabrics after repeated laundering. On the other hand, the fluoroalkyl groups of nano-type finishing agents turned round from fabric surface to fiber internal after repeated laundering. The water repellency of the wool fabrics treated with regular-type agent had a little changes according to the treatment condition changes and sharply decreased with repeated laundering. However, these values when treated with nano-type agents increased with the concentration and cure temperature and were maintained after 20 times laundering. The wool fabrics treated with nano-type agent had a great oil repellency irrespective of treatment conditions. Furthermore, the wrinkle recovery values of the wool fabrics treated with nano-type agents were higher than those of the fabrics treated with regular-type agent and were unchanged after 20 times laundering.
