| Outline of Research at the Start |
本研究期間では，未浸漬および水に浸漬中の単繊維や紡績糸，平織の静的引張試験および一軸疲労試験を実施する．また，超高速高精度寸法測定器を利用し，疲労試験直前や試験後，浸漬後の単繊維および紡績糸の直径や平織の厚さも測定する．さらに，走査型電子顕微鏡を用いて単繊維および紡績糸，平織の観察を行う．他にも繊維や紡績糸の摩耗,もしくは，疲労破壊が比較・検討しやすいよう平織(未浸漬および吸水させたもの)の平面摩耗試験を実施する．

| 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.
