- Abstract
There have been numerous attempts to characterise chemical resistance of geotextiles but not for humidity resistance. However, limited studies have been carried out on the Relative Humidity (RH) resistance of coir / polypropylene (PP) needle punched nonwoven geotextiles. In this study, the effects of relative humidity degradation on the mechanical properties of coir and coir / polypropylene needle punched nonwoven geotextiles have been reported. Tenacity, breaking elongation and penetration resistance decreases at various RH (45%, 65% and 85%) conditions with respect to time. It is observed that the polypropylene based nonwoven geotextiles (80:20 coir/pp and 60:40 coir/pp) have better mechanical performance than the 100% coir nonwoven geotextiles and that in turn depends on the nature of the environmental conditions, blend proportion and area density of the nonwoven geotextiles.
