Abstract
The decrease in fluid resistance is one of the important keys for the purpose of shortening of the sports time record. By wearing of a low resistance swimsuit, it still reminds us that there were a lot of large time record shortening in swimming races of Beijing Olympic. The development of low resistance cloth as the application to sports is very important. The fluid resistance were investigated by the change of cloth materials, surface roughness, surface processing method, seam position and the difference in sewing. This study is intended to suggest the best piece of cloth in specific speed area of sports.
