Researchers in Iran have successfully developed hematite nano-capsule as a non-toxic red pigment for use in the textile industry.
Scientists at Teheran's Tarbiat Modares University have produced the new pigment in collaboration with the Institute for Colour Science and Technology, affiliated to the Ministry of Science, Research and Technology.
Researchers said cadmium sulphoselenide-zirconium inclusion red pigments were developed for use as the commercial red colour in order to meet the need of textile industry.
The new varieties of nano-capsule or inclusion red pigments are also called non-similar or occluded pigments. They are produced by placing the unstable pigments in a bed of stable phases.
Modena University, Italy also served as a laboratory for the research work.
