Abstract:

In order to study the effect of different skin texture of fabric’ssurface affectstheair resistance,this paper studied the air friction resistance on the surface of fabric.Based on the principle of fluid mechanics, this paper analyzedthe force bearing statuson the surface of the fabric, and put forward the “fabric surface air friction drag mode”.The paper also put forward an index to measure the fabric’s air resistance performance. It’s a dimensionlessindex,the smaller the value, the better the fabric’s air resistance performance.The wind speed on the surface of 27 fabrics was testedby wind tunnel experiment. The experimental data was calculatedby Visual Basic (VB) programming combing with statistical correlation analysis. Thenfabric surface air friction drag model was set up.27 fabric’s air friction drag coefficients werebetween 0.183-0.271 .Fit the wind tunnel experiment of experiment data with the model by least square method, the result shows that the goodness of fit tests R ?^2of the experimental data of allfabricswas above 0.976. The fabric surface air friction drag model is highly reliable.
