Subsequently, chitosan and heparin were covalently bonded onto the AA-grafted PBT fibers. The surface graft density of modified PBT fibers was detected by dyeing and the hydrophilicity was evaluated by the contact angle. The results show that by the coupling of chitosan, the heparin-immobilized amount can be s
