When global market After producing synthetic dyes, the art of producing natural dyes is almost lost. Today, natural dyes are coming back to the market. Natural dyes are becoming more and more popular due to the increasing awareness of environmental protection. Natural dyes come from roots, bark, wood, berries, lichens, insects, shellfish and flowers.

More environmentally friendly dyestuff The increasing demand for technology has led to many research and development plans in the market, which will support the production of the same environment-friendly textile products. The Philippines Textile Research Institute (PTRI) has been able to meet the market demand through some projects, such as selecting the pilot scale of natural dye powder production and confirming the project. Application of textile technology 。

With the help of the technical monitor of the Philippines industrial and energy research and Development Commission (PCIERD-DOST), PTRI has developed several pilot scale production of dye resources, namely: mahogany, mahogany, Hainan peach, Talisay, ginger, tamarind and indigo.

According to project leader Julius Lea o, the main resources of these natural dyes show that the color fastness test results are satisfactory. In addition, the color uniformity and reproducibility of these selected dye resources have been improved and have been identified.

Compared with liquid dyes, these environmental friendly natural dyes have higher affinity with fabric materials. Similarly, compared with synthetic dyes, natural dye powder has good shelf life and repeatability. It has good color fastness to washing and is light in weight.

Because natural dye powder has market potential, PTRI is looking for potential technology providers.
