Perennial biofibers

On the basis of their life cycle, biofibers are divided into two types annual biofibers and perennial biofibers. Further, these biofibers are divided into different categories such as plant-based, animal-based, and mineral-based biofibers, depending upon their origin. Most plant fibers are composed of celluloses, hemicelluloses, lignins, pectins, and waxes, whereas animal fibers consist of proteins, for example, hair, silk, and wool. Plant fibers include stem fibers, leaf fibers, seeds, fruit wood, cereal crops, and other grass fibers.
