ABSTRACT
The present study is an attempt to evaluate the potentiality of a specified variety of banana fiber (Musa domestica var. balbisiana) for textile use. Retting period for extraction of the newer variety was optimized as 28 days in water. The extracted fibers were found to have cellulose content (58.5%), hemicelluloses (13.1%), lignin (7.4%) along with high fat and waxes (1.2%) and moisture (13.1%). SEM of the retted fibers demonstrated it to be a multicellular having lumen in each cell making it porous in the structure having hexagonal fibrils running through the axis. Bleaching improved the cellulose content (65%) fineness, and length diameter ratio, from 915 to 1147. The tensile strength (34.86 cN/tex), elongation (2.4%) and initial modulus (1727.7 cN/tex) of the retted fiber was reduced after bleaching. One hundred percent banana yarn was not strong enough for subsequent mechanical processes. Banana fibers can be processable in long staple jute processing system on their blending with ramie fiber having banana fiber content about 50% to produce fine blend yarn (213 tex) of tenacity 15.71 cN/tex at spinning speed 3500 rpm. It can also be concluded that banana fiber, which is till now being wasted after harvesting of fruits, showed good potential for value-added textiles.
摘要
本研究旨在评估香蕉纤维（Musa domestica var. balbisiana)在纺织上的应用潜力. 较新品种的浸提时间优化为28天. 提取的纤维含有纤维素（58.5%),半纤维素（13.1%),木质素（7.4%)以及高脂肪和蜡（1.2%)和水分（13.1%). 扫描电镜显示,它是一种多细胞纤维,每一个细胞都有内腔,使其具有多孔结构,六角形纤维贯穿于纤维轴. 漂白使纤维素含量（65%)细度和长径比从915提高到1147. 脱色后纤维的拉伸强度（34.86cn/tex),伸长率（2.4%)和初始模量（1727.7cn/tex)降低. 100%香蕉纱的强度不足以进行后续的机械加工. 香蕉纤维可在长绒麻加工系统中加工,与香蕉纤维含量约为50%的苎麻纤维混纺,以3500rpm的转速纺制出强度为15.71cn/tex的混纺细纱（213tex). 香蕉纤维是一种很有发展潜力的高附加值纺织品
