Fabric Materials and Sportswear Anti-Drag Performance Relationship

In this study four kinds of materials on the market most commonly used for sportswear are selected to knit one sports vest in plain style, woven by seamless circular knitting machine. We use wind tunnel tests to do the experiments and gather datum of experiments and analyze them to research the relationship between textile materials and wind resistance performance of sportswear. The results showed that: in the wind tunnel experiments, when wind speed is between 3.3 m/s and 9.35m/s, the wind resistance performance of the four experiment clothes is almost the same; When between 9.35 m/s and 11.00m/s, their wind resistance performance demonstrates a dispersion level; When it is between 11.00m/s and 18.70m/s, their differences of wind resistance performance between the four clothes are significant. The wind resistance performance could be sequenced from the good to the poor like this: 15.6tex combed cotton + coolmax modified polyester, 7.7tex/48f nylon, 15.6tex combed cotton, 9.7tex modal +15.6tex TC, and the fitting curve equation is obtained from the measured datum analysis through the SPSS software.
