Color in Motion:
Special Effect

With a trend towards spectacular color shift, Meadowbrook Inventions is developing and manufacturing a bold variety of color shift, reflecting and light refracting fibers. Angelina® fibers, sized as fine as 8 denier, make many different color shift effects possible.

* Iridescent color shift is due to light interference through two constituent types of polymers with different refractive indices. When light enters this structure, the shape produces an interference color, that is produced through the physical phenomenon of light interference alone.

Some iridescent Angelina® fibers, containing more than 100 layers of polyester and acrylic polymers, are produced in reflective color ranges and are suitable for dyeing and cross dyeing. They put "color in motion", making new fiber blends and textural effects possible in yarns.

* Another Angelina® fiber effect is a holographic color shift, occurring when light is reflected from a mirror surface of vacuum deposited aluminum through an optically transparent polymer embossed with a diffraction pattern of depth. As the viewing angle changes, entire spectrums of color are made visible dependent on light type, source, intensity and viewing directions, producing perceived color motion.

Multi-melanges with subtle, luminescent-iridescent highlights, soft metallic highlights, heavy metallic effects, clear sparkle highlights, brilliant color shifts or ultra high-tech color refractive sparks result, depending on the Angelina® fiber denier used and fiber saturation levels.
