Bamboo (Arundinaria clarkei ) short fibres were treated with 6% concentration NaoH solution for five different durations viz. 3h, 6h, 9h, 12h and 24h. Effect on physical properties like diameter and density were studied. Fibres were examined using Scanning Electron Microscope (SEM) to study the effect of alkali treatment on its surface characteristics. Single fibre tensile tests were conducted to assess the tensile strength of the fibres. Comparative study of the SEM micrographs indicated removal of outer layer with the surface irregularities becoming more prominent with increasing duration. The fibre surface was scanned using an Atomic Force Microscope (AFM) to quantify the increase in surface roughness with alkali treatment. Tests results showed positive effect on the strength till 6h beyond which the tensile strength was observed to reduce. Fourier Transform Infrared (FTIR) spectroscopy results indicated reduction in content of holocellulose along with hemicellulose, lignin and cellulose which explains the variation in tensile strength with increasing duration of treatment
