Fig. 1. Mechanical device for determining the elastic constants of coir 

 and abaca filaments. 



2. Comparative stress-deformation graphs of abaca and coir filaments, 



showing relative elasticity and resilience. 



3. Stress-deformation graphs of single, machine-cleaned, coir filaments; 



values taken from Table VII. 



4. Sectional profiles of 50-millimeter coir rope (full size).
