Natural fibers are excellent candidates for fiber-reinforced composites due to their excellent mechanical strength, biodegradability. However, the physical properties of natural fibers could not be consistent due to their inherent defects produced by cultivation, which might cause the poor mechanical properties as fillers in composites. To overcome these drawbacks, various synthetic polymer binders have been developed, but they have the disadvantage of causing environmental pollution and depletion of petroleum resources. In this study silk sericin, a natural glue-like protein, was used as a binder to produce a jute fiber nonwoven fabric. As the content of sericin increased, the density of nonwoven fabric increased and defects of nonwoven fabric were complemented. At a result the mechanical properties of the jute nonwoven fabric improved as sericin amount increased. These sericin binder are expected to replace synthetic polymer binders because they have excellent adhesion properties. |
