In this paper, polymer single fibers are prepared by electro‐spinning technology with different solvent rations, and the micromechanics properties are investigated together with the finite element analysis. It is found that the tensile stress–strain curves of single fibers can be attributed to two kinds of trends, which are independent of the solvent ratios. A possible arrangement model of polymer chains within the electrospun fibers is proposed according to the tensile stress–strain curves and the mechanics theories. The effect of polymer chains arrangement on the mechanical properties of the fibers is explored by the finite element analysis. This research shows a practical reference to predict the relationship between orientation degree of polymer chains and mechanical properties within the fibers.
