摘要: Recently, the use of lignocellulosic fibres to reinforcing composite has received an increased attention. However, lack good interfacial adhesion makes important treatment raw materials. Chemical prepared material be useful by elimination gummy and waxy substances. In this study, Luffa were treated tow methods: alkali mixed (sodium hydroxide hydrogen peroxide). The effect these treatments on structure was showed using SEM XRD (X-Ray Diffraction) analysis. results revealed that both resulted in a removal lignin, pectin hemicellulose substances, change characteristics surface topography. analysis shows increase crystallinity index many conditions. We find (120 °C; 3 h; 4% NaOH) cleaning higher fibres. It is also interesting note can from mat fibrils structure.
