Characterization of Sansevieria Fiber with NaOH Alkalization to Increase Tensile Strength

Abstract

Sanseviera fiber has physical and chemical characteristics that support it to be used as a biocomposite booster. The fiber length dimension obtained from decortivation can be maintained well even with a simple and inexpensive method. The tensile strength can be maintained well in the 10% NaOH alkaline treatment which is 1,35 N. The lignin and hemicellulose content can be lost effectively, thereby increasing the compatibility of adhesion with the resin. The alkali treatment was carried out at room temperature of 260 C, soaked for 4 hours, then rinsed to remove dust and other impurities. Alkalization serves to remove the lignin content in the fiber. The results of the FTIR test showed that the remaining lignin still persisted in the fiber at an absorption range of 1600 cm-1 with an aromatic group C=C which was shown from the FTIR peak graph. These results support the exploration of sansevieria fiber as a biocomposite booster.
