Summary of SANS tilting angle (angular axis) against isotropy (radial axis), measured in tangential plane, for experimental samples of Fabrics A, B and C, together with proposed expected ranges for different forming techniques. Yellow zones: wheel-throwing, WT, for clockwise (20° ≤ \({\alpha }_{Tan}\) ≤ 50°) and anticlockwise (– 50° ≤ \({\alpha }_{Tan}\) ≤ – 20°) wheel-rotation; Green zone: coil-building, CB, or coil-wheeling, CW, (– 15° ≤ \({\alpha }_{Tan}\) ≤ 15°); Grey zone: percussion-building, PB (0.950 ≤ \({I}_{Tan}\)≤1).
