Abstract

The interest of natural rubber (NR) product applications have been increased as natural rubber can be obtained from nature and it can be produce into sustainable products. It’s widely used in applications such as tires, wires, latex products, medical devices, and sport components. In this work, the use of electrospinning technique to produce fibers has been carried out because this technique has been proved to be a simple and effective technique for fiber production. This work aimed to study morphology, diameter, and functional group of natural rubber fibers, DPNR fibers, and different loadings of lignin in DPNR/lignin composite fibers produced by electrospinning technique. The condition for electrospun fibers were as following; needle-target distances of 15 cm and flow rate of 2.5 ml/h. The results of deproteinization by urea, SDS solution, and acetone showed protein in NR latex decreased. Moreover, increasing load of lignin resulted in an increase of the diameter of DPNR/lignin composite due to increasing of viscosity of the solution related to increasing of viscoelastic force. Characterizations of these fibers were reported using scanning electron microscopy to examine fibers surface and measure diameter of the fibers. Fourier transform infrared spectroscopy was used to examine the functional group of the fibers.
