The treatment of strong oxidizing agent NaIO4 with coconut
fibre (alkaline pH) resulted in more reduction in tensile properties
(breaking tenacity from 11.3 to 8.4 cN/tex, breaking elongation
from 21.5 to 14.3%, and specific work of rupture from 12.1 to
9.5 mJ/tex m) than in flexural rigidity (from 1273 to 1062 cN mm2).
