tensile strength, fineness and cross-sectional features of the raw fibres of
date-palm leaf were studied, The length, breadth, lumen size and length/breadth
ratio of the ultimate fibres were determined. Crimp frequency and crimp per cent
of alkali-treated fibres were also determined. The ultimate fibres were of
higher length but of lower breadth than those of high-quality jute fibres. The
length/breadth ratio also was much higher than that of high-quality jute fibre.</span>
