织物材料对运动服抗风阻性能的影响

The Materials' Influence on the Wind Resistance Performance of Sports Clothes

选取运动服中最常用的4种材料,用无缝针织圆机织造一款常见的运动背心,采用风洞实验、数据分析等方法,测定材料对运动服抗风阻性能的影响。结果显示:在风速为3.3～9.35m/s时,4种材料制作的服装的抗风阻性能几乎相同;在风速为9.35～11.00m/s时,其抗风阻性能开始出现一定的差异;风速为11.00～18.70m/s时,抗风阻性能差异明显,从好到差的顺序为15.6tex精梳棉+coolmax改性涤纶、7.7tex/48f尼龙、15.6tex精梳棉、9.7tex莫代尔+15.6texTC,并得出各自的拟合曲线方程。

This study selects four common materials used in athletic sports clothes usually, weaves four experiment clothes by using a common athletic sports clothes pattern with seamless knitting machines, through wind tunnel test and data analysis, gests the materials＇ influence on the wind resistance performance： in the experiment wind speed range, when wind speed is between 3.3 m/s and 9. 35 m/s, wind resistance performance of the four experiment clothes is almost the same;when wind speed is between 9.35 m/s and 11.00 m/s, the wind resistance performance of the four experiment clothes take out a dispersion degree;when wind speed is between 11.00 m/s and 18. 70 m/s, the wind resistance performance of the four experiment clothes appears a big difference, the wind resistance performance from good to bad is= 15.6 tex combed cotton ＋ coolmax modified polyester, 7. 7 tex/48f nylon, 15. 6 tex combed cotton, 9.7 tex modyer ＋ 15.6 tex TC, and the anthors also get the fitted curves of the measured data through the SPSS software analysis.
