: The natural fibers prepared from plant waste have parameters like fiberstrength, length, and chemical composition which are suitable to fabric and the fibersinto nonwoven. The selected plants were identified from their botanical names bycomparing the collected samples with those of known identity in the herbarium of abotanical survey in India with their names as Sesbania grandiflora, MutingiaCalabura, and Bauhinia Purpurea. A novel Portable multi-fibre decorticator machinewas fabricated and used to extract the fibers from the plant stem and barks. Theextracted fibers are done physical characterization and their properties areinvestigated. The extracted fibers are blended with other natural fibers like jute andflax in appropriate proportions 45:45:10 and nonwoven fabrics were prepared by theneedle-punching method. Three and four-layer nonwovens are produced using aneedle punching machine. The developed nonwovens are tested using standardapparatus and the effect of natural fibers in areal density, thickness; bulk density,porosity, and air permeability are analyzed. In addition, thermal conductivity andsound absorption behaviour are also investigated. The sound absorption propertyincreases concerning areal density and fabric thickness. The thermal conductivityincreased by increasing the fiber layer in the fabric to evaluate its potential as aprotective barrier material in non-woven face masks.
