Abstract: Polyblends of Styrene-Butadiene-Styrene (SBS) elastomer with ground Gum Arabic (G.A) Powder was made by Solution cast method by dissolving in toluene solvent. Tensiometer complex was used to monitor the deformational trend of the pure elastomer and the blend with Gum Arabic. The ultimate mechanical properties of the pure and blended samples were measured using Instron 4301 tensile testing machine. Results of the mechanical properties obtained following the deformation undergone by the test specimens were analyzed using a statistical analytical method, the 'analysis of the Covariance'(ANCOVA) method. Though the tensile set and stiffness of the pure elastomer were enhanced by the incorporation of Gum Arabic, the analysis showed that there was no significant difference in the tensile.......

Abstract:In ring frame, the edge fibres of the drafted strand either attached on the yarn surface or collected as waste at drafting set-up which affects the entire quality of the yarn. In this study, the parameters that will affect the drafted fibre strand width and the quantity of edge fibres going to be attached on the yarn surface such as total draft, break draft, traveller weight and twist level were varied and analysed. The increase in break draft and traveler weight increases the unevenness% of the yarn. This trend has been seen in all the samples. The increase in total draft slightly decreases...........
