Butterfly-Inspired Fibers Create Diverse Fabric Colors

Much like the Morpho butterfly’s microscopic wing structure, MORPHOTEX® fibers have various thicknesses and structures, which then determine specific colors. Thin films of 70-nm thickness, consisting either of polyester or nylon, are laminated in 61 alternating layers. By precisely controlling the layer thickness according to visible wavelength, four types of basic colors, including red, green, blue, and violet, can be developed. No dyes or pigments are used.

Depending on which dyed fibers are to be combined, or which methods are to be applied for spinning and weaving, the fibers produce diverse colors and improve material quality of fabrics. Due to their anisotropic characteristics and glossiness, the fibers are expected to have various applications in a wide range of fields, including painting, cosmetics, and craft works. MORPHOTEX® is already commercially used for clothing, nail polish, mascara, coating of musical instruments, and fishing rods.
