Butterflies as Models for Fabric Fiber Colors

Like butterfly wing structure, fibers of various thicknesses have been found to determine colors. Thin films of polyester or nylon of 70-nm thickness are laminated in 61 alternative layers, By controlling layer thickness according to visible wavelength, four colors are produced without using dyes or pigment: red, green, blue and violet.

The butterfly-inspired fibers produce diverse colors, improve material quality and are expected to be used in painting, cosmetics, crafts. The invention is patented, commercialized and identified as "Morphotex" used for clothing, nail polish, mascara, coating musical instruments and fishing rods as reported in NASA Tech Briefs, July 2011, p. 33 -- see also for the full report.
