Correlation degree between structural parameters and air permeability was calculated by testing structural parameters & air permeability of eight kinds of wool fabric and using grey system principle. At first, comparative and referenced sequence were got, then datas were dimensionless, finally the order of the result was proposed. The result showed that the structure parameters were warp density, weft density, weight per square meter of fabric, weft fineness, warp fineness, thickness, warp tightness, weft tightness, total tightness in order. Draping coefficient of fabric and its main influence factors were analyzed quantitatively through linear regression model and it showed that the relation between density of warp and yarn and air permeability was negative correlation.
