Animal hair fiber can improve the hand feel,luster,dyeing performance and anti pilling performance of the fabric by stripping the forest.The wool fiber after peeling becomes even more difficult in fiber identification.By using potassium permanganate thiourea dioxide redox method to strip the standard samples of seven common wool fibers,a group of standard samples of longitudinal section after stripping were obtained.Observe the longitudi-nal section shape of the unknown peeled fur fiber with a microscope,and identify the type of the unknown peeled fur fiber by comparing the longitudinal section shape of the standard sample.The results showed that when the concentration of potassium permanganate was 0.375％,the temperature was 60 ℃,and the oscillation time was 40 minutes,the effect of forest stripping was the best,and the shape of longitudinal section was the best.
