Effects of cellulase on the modification of cellulose. Lignin content induces higher thermal stability to nano-whiskers (rosa et al., 2010). Exposure may be due to cross-linking between the molecular chains of cellulose. Kg of yarn, which is boiled in the bath for about an hour. Rope/yarn requires 12–20 times of water, respectively, using hydrogen peroxide.
Sri lanka remains the world's largest exporter of coir fibre and coir fibre based products. The segments of the husk are then beaten with iron rods to separate out the long fibres which are subsequently dried and cleaned. "Influence of fibre surface treatment on structural, thermal and mechanical properties of jute fibre and its composite", bull material science, v. 32, n.1, pp. 65-76, 2009.
Figure 3a-d shows that in the third treatment the grooves on the surface of the coconut fiber are covered by h2o2 solution in the form of patches. Although the fiber grooves covered by patches the tensile strength of the fiber tends to fall with increasing concentrations of hydrogen peroxide,Coconut fibre as shown in figure 5. This is due to the fact that the patches are not able to properly fill the grooves and does not become a single unit as seen clearly in figure 3a-d.
The coconut fibre used by us is obtained from the fibre padding of coconuts. The fibres of mature and fully mature fruits contain a higher proportion of wood and are used as filling material for mattresses and upholstery. Before processing the fibres are cleaned, stored in sea water (this causes the pectin to rot – a process also known as roasting) and then dried in the sun. The fibres are traditionally loosened by tapping and are sorted according to colour and fineness. They consist of approx 45% lignin and 44% cellulose.
The mats protect seeds from extreme fluctuations in temperature, creating favourable conditions for germination. Coconut-fibre mats and jute-fibre mats provide a cost-effective solution for protecting embankments, river banks and shore areas from the undesirable erosion of soil caused by the effects of water and wind.

Ftir spectra; physical and chemical behavior of coir. Drastic fall in the activation energy of the fibre up to treatment with 30% naoh. Quality, segregation of fibres into three grades as coarse, medium and fine is needed. Fibre content of a husk distinctly shows three groups viz. Near ripe to ripe nuts are reported to give best fibres .
Population growth and the increasing search for healthy foods have led to a major consumption of coconut water and, hence, to an environmental impact caused by the inappropriate disposal of green coconut husks. This lignocellulosic biomass has deserved attention of researchers concerning the seeking of new usages, as, for example, in renewable fuels production technologies. This study examines the potential of green coconut husk fibers as a feedstock for the production of bioethanol. The coconut fibers were pretreated through an alkaline method, hydrolyzed enzymatically and submitted to ethanol fermentation with commercial yeasts of saccharomyces cerevisiae.
