In vision of recent worldwide environmental issues, scientists have begun to show interest in developing the full potential of natural fibers and their assorted uses. Historically most of the methods used for the extraction of the sisal fiber inclusively the natural retting and mechanical process is not efficient in the removal of fibre compounds. In this study is related to how the impurities are removed from the fiber for apparel use. The alkali treatment, acidic treatment and treatment with varying solution of sodium salts is performed. The extractions of fibre have two stages, preliminary stage and laboratory stage. Primarily attaining maturity, sisal leaves was harvested manually by cutting from the leaf base with a sharp specialized crescent like knife having long handle. The harvested the fibres were systematically washed with distilled water and dried in a vacuum oven pre-set at 80ºC for 24 hours after which raw fibres were sampled. They were then treated with diethyl ether: petroleum ether: Ethanol (2:2:1), followed by ethanol. After the extraction process was completed, the length, diameter, moisture adsorption properties, physical shape, color, the visual appearance of fibre after treated with NaOH and some other physico-chemical properties of fibre will be evaluated.
