Abstract
The success of suture yarn depends upon its tensile and bending properties. As sutures pass through the tissue, it should possess enough strength to hold the tissue together and should be flexible so as to be knotted. The aim of the present work was to improve the strength of silk suture without affecting its bending properties. Silk sutures were fabricated using a circular braiding machine. Structural variations were made by varying the diameter and by producing core sheath suture yarn. The resulting suture yarn is coated with chitosan – a biopolymer. The mechanical performances of suture materials coated with and without chitosan were studied and compared with commercial suture. It was observed that the suture with a core-sheath structure performed well during tensile and knot testing. The coarser yarns exhibited higher bending rigidity and lower knot strength than the finer suture yarns.
