Comparison of Morphological and Chemical Properties of Musa Velutina Fiber Extracted through Different Extraction Method

ABSTRACT

Natural fibers are being used for the last few decades as an alternative to synthetic fibers for their eco-friendly nature. But still, there is a scientific gap to address cost-effective and environmentally sustainable fiber extraction method with minimum waste production. Therefore, a study was carried out on the extraction of fiber from naturally occurring Musa velutina (wild banana plant) adopting different extraction methods. Wild banana plant fiber was extracted by chemical and biological process. Chemical extraction was carried out using Sodium hydroxide at two different concentrations (3% and 5%). The temperature was maintained at 100 ± 50°C and the bath ratio maintained at 1:7 for 2 h. Fiber yield was obtained from 20.32% to 22.56% for both concentrations. Similarly, the biological retting process was also executed using potential lignolytic bacterial (e.g. Bacillusacidicola) and fungal (e.g. Chaetomium sp.) strains. Fiber yield in the biological process was obtained at the range 21.32–31.02%. Proximate chemical analysis and SEM of extracted fiber were determined. Among the methods, the biological extraction method is found suitable in comparison to the chemical process.

过去几十年来,天然纤维因其5种环保性质而被用作合成纤维的替代品. 但是,在解决成本效益高、环境可持续的纤维提取方法和最少的废物产生方面仍然存在科学差距. 因此,7采用不同的提取方法,对天然香蕉(野生8种香蕉植物)的纤维提取进行了研究. 采用9种化学和生物方法提取野生香蕉植物纤维. 使用氢氧化钠在两种不同浓度(3&5%)下进行化学提取. 温度保持在100±500°C,11浴比保持在1:7,持续2小时. 在两种浓度下,纤维产率在20.32-22.56%之间. 同样,生物脱胶过程也使用潜在的13种木质素降解细菌(如芽孢杆菌)和真菌(如毛壳菌)菌株进行. 在14个生物过程中.纤维产率在21.32-31.02%之间. 对提取的纤维进行了化学分析和扫描电镜观察. 在这些方法中,生物萃取法与化学法相比是合适的. 17

Highlights

1. In this paper, we show that the extraction process of bast plant fiber, with emphasis on the microbial retting process.

2. This works attempt has been made to extract fibers from Musa velutina pseudostem and optimized the fiber extraction processes and evaluated the properties of fibers.

3. It is evident that enzymatic biological extraction results in higher crystalline values, hence it increases the fiber strength, whereas chemical extraction results in the lowest diameter and crystalline values.

4. The overall results of this study open up new avenues for an investigation related to fiber extraction, concerning biological extraction to obtain fine fiber that could be used for the production of textile and automobile industries.
