Some studies on 100% banana parallel laid and 60:40% banana: polypropylene cross laid non-woven fabrics

Abstract

Global trend towards sustainable developments have brought natural, renewable biodegradable raw material into the focus, but due to lack of technical knowhow, only a small fraction of these non-conventional fibres are harvested and utilized. In this study we have developed parallel laid 100% banana nonwoven fabric and cross laid banana/polypropylene (60:40) nonwoven fabric. Three varieties of banana fibers namely Mahalaxmi, Shrimanti and Graint Naine were used for needle punched non-woven fabric preparations. Analysis of physical properties is carried out in machine direction and cross direction. This paper concludes that cross laid nonwoven fabric show superior tensile properties as compared to parallel laid nonwoven fabric. Shrimanti fibre nonwoven fabric is stronger than Graint Naine and Mahalaxmi fibre nonwoven fabric for both the parallel laid and cross laid structure. Parallel laid Mahalaxmi banana nonwoven fabric and cross laid Graint Naine banana nonwoven fabric gives higher elongation% for machine and cross direction. Increased air permeability of cross laid (60:40) banana/polypropylene non-woven fabric observed than parallel laid 100% banana non-woven fabric. Parallel laid Graint Naine non-woven fabric showed higher air permeability than Shrimanti and Mahalaxmi parallel laid non-woven fabric. Bursting strength of parallel laid nonwoven fabric is higher, both in the machine as well as in cross direction than cross laid nonwoven fabric for three varieties of banana fibres. Shrimanti banana non-woven fabric showed higher bursting strength for parallel laid and cross laid structure than Graint Naine and Mahalaxmi parallel laid and cross laid structure.
