ABSTRACT

Corn leaves were collected after harvesting corn and the fibers were extracted by water retting. The fibers were subjected to alkali treatment in order to enhance the mechanical as well as handle properties. The physico-mechanical properties of the retted and alkali-treated corn leaf fibers were analyzed using various analytical and statistical methods. The change in chemical composition due to alkali treatment was determined using Fourier transmission infrared spectroscopy and chemical composition analysis. Results inferred that 15 days retting gives better quality of fibers. The alkali treatment resulted in the removal of lignin, fats, and waxes as well as the disintegration of individual fibers from the retted fiber bunch. Bundle strength, elongation, and moisture properties were found to improve after chemical treatment. The study shows that corn leaf fiber has good potential in technical textile applications.

摘要

收获玉米后收集玉米叶并通过水沤提取纤维。对纤维进行碱处理以提高机械性能和手感性能。使用各种分析和统计方法分析了浸湿和碱处理的玉米叶纤维的物理机械性能。使用傅里叶透射红外光谱和化学成分分析来确定由于碱处理引起的化学成分变化。结果推断，15 天的沤麻可提供更好的纤维质量。碱处理导致木质素、脂肪和蜡的去除以及单根纤维从沤软纤维束中解体。发现化学处理后束强度、伸长率和水分性能得到改善。
