Studies on morphological structure, physical properties and colour strength of infrared dyed pineapple leaf fibre / Anis Nazahah Mohd Amin

Pineapple is one of the most widely grown crops in Malaysia. It is usually consumed in fresh fruit selling and juice drinks. However, the widespread use of pineapple resulted in large agricultural waste of pineapple leaves that are poorly maintained by the authorities in Malaysia. Therefore, this st...
