RESUMO
The aim of this study was to investigate the effect of surface treatment on the properties of waste piassava fiber with the goal of aggregating additional business value. The fiber surface was subjected to four different treatments. In the present work, it was found that washing the fibers with water partially removed impurities from the surface rendering it rougher. Alkaline treatment removed impurities from the surface, hemicellulose and lignin, improving the flexibility of the fibers. Increasing the concentration of washing agents, times and temperature of treatment promoted intense defibrillation on the fiber surface, reducing its strength.
