"Prediction of the Air Permeability of Woven Fabrics Using Neural Networks," International Journal of Clothing Science and Technology, Vol. 19, #1, pp. 18-35. Description: Structural factors relating to air permeability for 30 fabric types. Data are mean and SD of 5 replicates per fabric. Model 1: E{AP} = B0 + B1*Warp + B2*Weft + B3*Mass Model 2: E{AP} = C0 + C1*Water + c2*(Water^2) Variable Names: sampNum warp (warp yarn density, ends/cm) weft (weft " " , picks/cm) mass (mass per unit area, gr/m^2) airPermMn (average air permeability, cm^2/s/cm^2) airPermAD (Std Dev of air perm measurements) waterCont (Water Content after vacuum drying, %)
