PURPOSE:To obtain the title structure capable of maintaining durability free from reduction in performances by repeated use and washing by sealing microcapsules having a sealed anti-fogging agent to fiber gaps of ultrathin fibers constituting cloth containing ultrathin fibers. CONSTITUTION:A fiber structure such as woven and knit fabric or nonwoven fabric containing conjugate fiber of fibrillation type capable of being made into <=0.7d fineness of single fiber is fibrillated and microcapsules comprising an organic polymer such as polyurethane as a wall agent and a sealed anti- fogging agent such as fluorine-based surfactant is sealed to fibers gaps of ultrathin fibers constituting the fiber structure to give a cleaning and wiping fiber structure. The fiber structure having anti-fogging action has washing durability, exhibits characteristics thereof for a long period of time and is widely useful for wiping lenses, etc. |
