The Effect of Sodium hydroxide on Chemical and Mechanical Properties of Corn Husk Fiber

摘要

There are thousands of different fibers in the world and in fact, only a few of these fibershave been studied. This report concentrates on the chemical, and tensile strength properties of corn husk fibers treated NaOH 5% for 2 h.The result indicates that the alkali treatment with NaOH 5% removed the hemicelluloses and lignin in the fibers and decreased the moisture content. Consequently, the higher cellulose content obtained by 54.37%, and tensile strength properties of fibers were greatly improved of 237.43 ± 104.82. Moreover, their properties are comparable to most natural fiber. Scanning electron microscopy analysis indicated the presence of rough surfaces and a number of lumens inside the fiber bundles. These valuable of data very encouraging the usage of Corn husk fibers (CHFs) for the application in fiber industries, composite manufacturing, etc.
