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.

对100％香蕉平行编织和60：40％香蕉：聚丙烯交叉编织无纺布的一些研究

全球可持续发展趋势已将天然的，可再生的可生物降解的原材料作为重点，但是由于缺乏技术知识，这些非常规纤维中只有一小部分被收获和利用。在这项研究中，我们开发了平行铺设的100％香蕉无纺布和交叉铺设的香蕉/聚丙烯（60:40）无纺布。三种香蕉纤维，即Mahalaxmi，Shrimanti和Graint Naine用于针刺无纺布制品。物理性质的分析是沿纵向和横向进行的。本文得出的结论是，与平行铺设的非织造布相比，交叉铺设的非织造布具有更好的拉伸性能。Shrimanti纤维无纺布在平行和交叉结构方面都比Graint Naine和Mahalaxmi纤维无纺布更强。平行铺设的Mahalaxmi香蕉无纺布和交叉铺设的Graint Naine香蕉无纺布在纵向和横向上均具有较高的伸长率。观察到与平行铺设的100％香蕉无纺布相比，交叉铺设（60:40）香蕉/聚丙烯无纺布的透气性增加。平行铺设的Graint Naine无纺布比Shrimanti和Mahalaxmi平行铺设的无纺布显示出更高的透气性。对于三种香蕉纤维，平行横纹无纺布的破裂强度在机器方向和横向上均比交叉横纹无纺布高。
