Abstract: The banana being the world’s largest herb and given its gigantic nature, produces huge amount of biomass. Among the various parts of banana, the biomass production is more in pseudostem ( 34-37%). Banana sheath contains cellulose fibres embedded in a matrix of other materials. The major components of matrix are water, lignin and polysaccharide like pectin, starch and hemi-cellulose. Extraction of fibre from banana sheath can be done either by mechanical extraction or by hand stripping. Other than these two methods, fibre can also be extracted by retting process. Each method presents, its own advantages and drawbacks, which influence the amount and quality of fibre obtained. In the present study a comparison has been made of different extraction procedures like mechanical, chemical and microbial and its effect on yield, quality and composition of fibres from banana pseudostem. The fibre yield was highest in tap water and least in mechanical retting process. Among all the treatments highest cellulose yield was found in chemical retting process and lowest in microbial. The pectin content was highest in mechanical process and lowest in chemical retting. The lignin was lowest in chemical and highest in tap water retting. The quality of fibre in terms of tenacity was highest in chemical retting suggesting that this fibre would give better yarn. It also had low Tex Value indicating that the fibre was very fine. It was concluded that among the different processes of extracting fibre from banana pseudostem the chemical retting process using sodium hydroxide (0.5 – 1.0%) was best to obtain superior quality of fibre.
