Polylactide fibers containing different amounts of glycerol triacetate(GTA) were prepared by electrospinning.The fibers were characterized by environmental scanning electron microscopy,differential scanning calorimetry,water contact angle and mechanical properties.With increasing GTA content,the fibers became to adhere to each other and a network was formed,and as a result,the elongation at break,recovery ratio and tensile strength of the fibers could reach 200%,85% and 4.24 MPa,respectively.At a GTA content of over 50%,the fiber mats were capable of sucking water quickly.
