ABSTRACT = {The aim of this study is to optimize the process parameters of alkali treated Saharan aloe vera
cactus fibres using of Box-behnken experimental design. The Saharan aloe vera cactus fibres
were treated with different concentration of NaOH, soaking time and temperature which affect
the properties of fibres and plays main role in removal of lignin, hemicellulose, pectin and wax
content. The chemical composition of untreated and treated fibres was analyzed by standard
methods. XRD result shows the improvement in the crystallinity index of fibres due to alkali
treatment. ATR-FTIR analysis shows that hemicellulose and lignin were decreased in all alkali
treated fibres. SEM micrographs show the surface roughness in alkali treated fibres. Mechanical
properties for the treated and untreated fibres were tested and analysed through single fibre
tensile strength tester. TGA proves that thermal stability and decomposition temperature were
increased for alkali treated fibres.},
