Description	369-374 The dyeable poly (lactic acid) (PLA) has been prepared based on the fundamental of nanotechnology. PLA is melt-mixed with montmorillonite (MMT) and quaternary ammonium compound using twin-screw extruder to achieve PLA/modified MMT nanocomposite. The nanocomposite fibre is then prepared using single-screw extruder for further investigations including dyeability, structural analysis, and thermal properties. The results show that the nanocomposite fibre is dyeable with both acid dyes (anionic dyes) and basic dyes (cationic dyes) due to the presence of dye sites, quaternary ammonium cation and anionic charge of MMT particles respectively. The color strength is found to be dependent on the amounts of quaternary ammonium compound as well as MMT applied. The fastness properties such as wash fastness and light fastness show similar trend as found in the traditional fibres. It is observed that the thermal stability of the nanocomposite fibre is lower than that of neat PLA fibre. This study demonstrates that PLA can exhibit the dyeability in the form of nanocomposite.
