  Abstract

This study combines and twists 75D polyester (PET) multi-filaments and polylactic acid (PLA) multi-filaments with twist coefficients of 2, 3, 4, 5, and 6 to form 150D PET/PLA plied yarns. The 0.08-mm-diameter stainless steel (SS) fibers are made into SS braids with a 60-tooth braid gear and a take-up gear with 60, 70, 80, 90, or 100 teeth. PET/PLA plied yarn and SS braids are then combined and electrochemically treated with an electric current of 100, 200, 300, 400, or 500 mA at 60 for 24 hours, forming the PET/PLA/SS composite bone scaffolds. PET/PLA/SS composite bone scaffolds are observed by scanning electron microscope (SEM) and energy dispersive spectroscope (EDS), and tested for weight increase rate and biocompatibility. The experiment results show that the optimal twist coefficient for PET/PLA plied yarn is 4 and the optimal tooth number on the take-up gear for SS braids is 80. SEM observation result shows that hydroxyapatite (HA) deposits on the surface of PET/PLA/SS composite bone scaffolds and attaches to the PET/PLA plied yarns. Finally, regardless of electric currents, all PET/PLA/SS composite bone scaffolds possess good biocompatibility.
