The research wing of the Coir Board was formed in 1955 as per the recommendation of the committee for Research and Statistics of Coir Board and the Central Coir Research Institute started functioning in 1959. A wet processing laboratory was set up in the initial stage and subsequently it was bifurcated into the Dye House and Chemistry & Testing Laboratory in 1984. The Dye House has been looking on bulk dyeing/ bleaching of coir fibre/ yarn by mechanical steam dyeing process. The Chemistry & Testing Laboratory is housed in the new research block of CCRI and is responsible in continually improving the quality of dyeing, bleaching, shade matching through research investigations by adopting appropriate chemicals and technology . It is instrumental in evolving shadecards on Direct and Reacitive dyes and also from Eco-friendly direct and acid dyes. It evolved a low cost bleaching technique for the benefit of the coir industry and engaged in development of a silicate free Hydrogen Peroxide bleaching. It attend to the requirements of the trade in shade matching by conducting lab level dyeing. It is also involved in imparting softness to coir fibre, fire retardency and water repellency to coir and coir products. It has a Physical Testing Laboratory recognized by Bureau of Indian Standards in testing of coir and coir products as per IS standards. Recently it has set up an ASTM laboratory for testing the characterizations of Coir Bhoovastra as per ASTM standards
