ABSTRACT

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.
