ABSTRACT

Banana silk, a fiber extracted from the pseudo-stem of banana plant, is used widely for various applications. Same way, the bracts of banana inflorescence contains substantial quantities of fibers, which could be used in various textile applications on account of its physical and chemical properties. The fibers are found to have high cellulose content of 56.48% and low wax content of 1.05%. The density of the extracted fibers is found to be 1.39 g/cc. The extracted fiber length ranged from about 22 to 33 cm with an average fiber length of 27.6 cm. Diameter of the fiber sample is found to be 79.6 µm. The fiber exhibited a mean breaking strength of 60.1 gf, tensile strength of 178.17 Mpa, and a mean breaking elongation of 20.9% and Young’s Modulus of 2.99 GPa. Thermo-gravimetric analysis showed that the fibers are stable up to 200°C, decomposes at 400°C and leaves a residual char content to the extent of 15.48% at about 800°C. Based on the properties, the banana inflorescence bract fibers could be used as a substitute for synthetic fibers in making non-wovens and textile composites.

摘要

香蕉丝是一种从香蕉植物的假茎中提取的纤维，广泛用于各种应用。同样，香蕉花序的苞片含有大量纤维，由于其物理和化学特性，可用于各种纺织应用。发现这些纤维具有 56.48% 的高纤维素含量和 1.05% 的低蜡含量。发现提取纤维的密度为 1.39 g/cc。提取的纤维长度范围为约 22 至 33 厘米，平均纤维长度为 27.6 厘米。发现纤维样品的直径为 79.6 µm。该纤维的平均断裂强度为 60.1 gf，拉伸强度为 178.17 Mpa，平均断裂伸长率为 20.9%，杨氏模量为 2.99 GPa。热重分析表明，纤维在高达 200°C 时仍保持稳定，在 400°C 时分解并在约 800°C 时留下 15.48% 的残余炭含量。基于这些特性，香蕉花序苞片纤维可替代合成纤维用于制造无纺布和纺织复合材料。
