The Kyoto Municipal Industrial Research Institute Textile Technology Center has introduced a processing method that can create three dimensional (3D) effects on wool fabric using ultra violet light.

"Emphasis is placed more and more on environmental protection in the textile processing industries owing to their high burden on the environment," said Institute technologist Satoshi Ogawa.

"Under these circumstances, we developed two new processing methods utilising light energy and minimising the load on the environment."

First the scientists have discovered a processing method to give 3D effects on wool fabric, which is obtained by radiation with ultra violet light (UV) at high intensity.

The second are new textile products with high visual effects, such as those seen in advertisements that can be seen from the leading edge and change to another image once the observer passes in front of the ad. This is achieved using photosensitive resins said Ogawa.

Photosensitive resin is a type of resin with high transparency that can be cured by UV radiation. From an energy-saving point of view, photosensitive resin is gaining popularity in certain industries.

Using this technique the Kyoto labs have produced a high visual effect textile by coating a photosensitive resin on the fabric printed with a pattern composed of fine lines, which shows color changes or 3D effects as the viewing angle changes.
