The United Nations Educational, Scientific and Cultural Organization (UNESCO) proclaimed in 2005 that Ugandan bark cloth is largely produced from mutuba tree (Ficus natalensis) as a “Masterpiece of the Oral and Intangible Heritage of Humanity.” An exploratory investigation of bark cloth a nonwoven material produced through a series of pummeling processes from mutuba tree in Uganda is fronted as a prospective engineering natural fabric. Bark cloth was obtained from Ficus natalensis trees in Nsangwa village, Buyijja parish in Mpigi district, Central Uganda. The morphology of the fabric was investigated using scanning electron microscope (SEM). thermal behavior of the fabric was studied using thermagravimetric analysis (TGA) and differential scanning calorimetry (DSC). Fourier transform infrared spectroscopy was used to evaluate the surface functional groups. The fabric was subjected to alkaline treatment for six hours at room temperature in order to study the change in fabric thermal properties so as to set a base for applications in biodegradable composites. Findings show that the natural nonwoven fleece is stable below 200°C; alkaline treatment positively influences the thermal behavior by increasing the onset of cellulose degradation temperature. The fabric morphology showed that it is made up of fairly ordered microfibers which can be beneficial for nanocomposites.

Abstract. This article described about the effect of surface modification on newly identified natural fiber in the name of veldt grape stem fibers (cissus quadrangularis) were extracted and investicated. The extracted veldt grape stem fibers (VSF) is treated with alkali chemical with various concentrations like 5%, 10 % and 15 % for a constant soaking time of 60 min. The true cross sectional areas were measured for treated and untreated fibers using electron microscope and image J software. The tensile properties of chemically treated fiber were studied using Instron universal testing machine and found the better tensile properties on 10% chemical concentrations, which considered as optimum case of alkali treatment. The fibers density, chemical compositions like cellulose, lignin, wax, moisture and ash content also studied for optimal case based on tensile strength. The characterization of optimally NaOH treated fibers was analysed by using of XRD technique.
