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 modern Dye House and Chemistry & Testing Laboratory in 1984. The Dye House has been conducting bulk dyeing/ bleaching of coir fibre/ yarn by mechanical steam dyeing process. The polymer technology, geo textiles, Chemistry & Testing Laboratory is housed in the Research Block of CCRI and carries out R&D studies to continually improving the quality of dyeing, bleaching, shade matching through experiment & trial investigations by adopting appropriate chemicals and technology . The Department is  instrumental in evolving shade cards using Direct and Reactive dyes and also from natural dyes. The department has recently developed a Pantone Shade Card on colours for coir.  The Department 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 caters to the requirements of the coir trade for 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. The Physical Testing Laboratory has been recognized by Bureau of Indian Standards for testing of coir and coir products as per IS standards. It has set up an ASTM laboratory for testing the characteristics of Coir Bhoovastra (geo textiles) as per ASTM standards.  Apart from that the lab conducts tests the additives such as fillers and NR latex.  Innovative coir products have been developed using coir-polymer composites such as moulded and injection moulded products.  The lab has successfully developed the coir fibre reinforced green injection moulded PP chairs, and is in the process of developing coir composites boards using natural resins and glues which can be used in the building/construction industries.  An important project underway in the Department is to develop coir cushioning with specifications as per the Railway Research Design and Standards Organization (RDSO) Lucknow.  This will lead to re introduction of coir cushioning in the railway carriages in Indian Railways.
