In India, there is a significant supply-demand imbalance for wood and wood products. In the current scenario, effective utilization of existing lesser-known species such as Cocos nucifera L. (Coconut palm tree) is gaining prominence and will help to bridge the supply-demand gap for timber. This study aims to develop moisture content-based experimental kiln drying schedules for solid flooring (Tongue and Groove (T&G) and Parquetry flooring) and engineered overlay flooring made from high and medium density of west coast tall coconut palm wood, respectively. Freshly cut samples were graded into density classes and their average moisture content (%) was calculated. A quick drying test (QDT) was performed to investigate the degree and type of drying defects. The Terazawa method was used to develop the base kiln-drying schedules, which were then optimized using Rasialy classification. For better output of T&G flooring and Parquetry flooring materials, experimental kiln drying schedules MT4-B1 and MT6-B1 (Schedule codes) should be set in kiln drying machine for 50 mm and 25 mm thick high-density coconut palm wood, respectively. The experimental kiln-drying schedules recommended for medium-density wood with thicknesses of 50 mm and 25 mm were MT6-D2 and MT6-E1, respectively. All schedules are created with the desired moisture content (12%) for general flooring purposes in prevailing conditions of Kerala, as prescribed by the Bureau of Indian Standards.References
