Résumé

In an attempt to increase biodiversity in natural plant fiber nonwovens, new sources of natural fibers must be discovered. Nonwoven fabric is a promising commercial product for upgrading the new bast fiber Triumfetta cordifolia (TCF) and giving it an opportunity to be used in composite nonwoven applications. Two types of TCF nonwoven mats blended with polylactide fibers for one and polypropylene fibers for the other at a mass ratio of 50 : 50 were manufactured using carding and needling technology. The aim of the present work is to compare the different types of TCFbased nonwovens with other nonwovens based on commercial bast fibers, namely flax and hemp, known for their use in automotive interiors. The nonwoven fabrics were characterized in terms of weight per unit area, thickness, tensile strength and flexural rigidity. In addition, morphological aspects of fiber organization, density and distribution within the nonwoven reinforcement were observed using Scanning Electron Microscopy. The results revealed great variability in terms of surface density and thickness. Increasing the surface mass of nonwovens led to an increase in mechanical performance in terms of strength and stiffness, while retaining anisotropy in terms of fiber orientation, which has a significant effect on mechanical behavior due to the preferential fiber orientation generated during carding. In addition, the type of thermoplastic polymer fiber in the nonwoven mat has an influence on the characteristics evaluated. The results obtained showed that TCFs are good candidates, given their competitive performance and availability compared with flax and hemp fibers, and that they can be used in the same composite applications. Such a non-woven mattress based on TCFs from the tropical African region, manufactured using carding and needling technology, could open up opportunities to create new value-added products that can benefit these countries from an economic and ecological point of view.
