Structure and Characteristics of Pineapple Leaf Fibers Obtained from Pineapple Leaves

Pineapple leaf fiber is a nature hemp leaf fiber extracted from pineapple leaves. Its structural characteristics was investigated by means of scanning electron microscope (SEM), X-ray diffraction (XRD), Differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). The results showed that the percent crystallinity and preferred orientation of crystallites in pineapple fibers were 60.82% and 98.5%, respectively. The average fracture strength of the pineapple leaf fiber is high and the linear density is low, so there is a high fiber spinnability and yarn quality. The present study is expected to provide essential information for the preparation and processing of pineapple leaf fibers.
