Abstract The principles of biomimicry were used to develop novel textile structures inspired from the Morpho butterfly’s wing scale, primarily for technical applications. Bio-mimetic virtual abstract 3D proxy models of knitted structures were developed. The models were mapped onto the original biological templates and then on the knitted fabrics. Image segmentation methods such as binarize, local adaptive threshold and morphological threshold were employed concurrently to ‘digitise’ the biological template, 3D models and knitted fabrics. Eight samples mimicking the Morpho scales were knitted. Euclidean distance measurement and pixel values, established that the biological template, selected 3D geometrical models and physical knitted fabrics have a high degree of similarity. Local adaptive threshold gave better results for pixel intensity differences while the morphological threshold method generated better results when measuring Euclidean distance.
