Application of needle punch technique in bamboo-based medium density fibre board
The Fiber boards were prepared using D. strictus as lignocellulosic fibre and phenol formaldehyde (conc.8 %) as resin with three different pressures i.e. 14, 17.5 and 21 kg/cm2 for 15 minutes hot pressing at 150 0C. Simultaneously, needle punching treatments were applied on resin blended bamboo fibres during the mat formation i.e., one, two, three and four times punching. The physical and mechanical properties i.e. density, moisture content, water absorption, general swelling, surface absorption, modulus of rupture, tensile strength perpendicular to grain (internal bond strength) and screw withdrawal strength of both type (punching and non-punching) MDF boards were tested as per Indian Standard specification IS: 12406. The results revealed that the physical and mechanical properties of MDF board were significantly improved by needle punch technique and the board made from bamboo (D. strictus) using three-time needle punching with pressed at 21 kg/cm2 specific pressures were meet the requirements of Indian Standard specification IS: 12406.
