Outline of Final Research Achievements

We should be examined the study on fatigue property of cloth using natural fiber for SDGs of fiber products. Wool, silk and cotton fibers as natural fiber has special structure and hydrophilicity. Mechanical properties of the cloth using natural fiber will be improved by wet treatment. So, study on fatigue property of cloth using natural fiber after wet condition was investigated for improvement. As a result, cloths using wool and silk fibers have good fatigue life after wet condition. But fatigue life of cloth using cotton fiber at dry condition was longer than that of the cloth using cotton fiber at wet condition. Therefore, the fatigue life of cloth using natural fiber was probably affected by structure in the cloth because wool, silk and cotton fibers absorbed moisture.
