Tensile strength was determined on the one hand as collective
strength measured by Stelometer and on the other
hand as single element strength measured by using Dia-
Stron. The cotton fibres’ collective strength (15.1 cN/tex)
was less than half of their single element strength (36.9 cN/
tex). Kenaf fibres had a collective strength of 27.8 cN/tex and
a single element strength of 41.6 cN/tex. The collective
strength is always lower than the single element strength
