Study on functional polyester semi-inlaid with sucrose ester and grafted with sericin protein

In this paper,polyester was firstly semi-inlaid with sucrose ester,and then grafted with sericin protein with crosslinking agent.SEM Image showed that after inlaying,a layer of compound was covered on the surface of the polyester fiber,and after grafting,the covered layer became thicker.FT-IR indicated that sericin protein had been grafted onto the polyester.DSC showed that the thermal stability of the polyester had been improved.XRD showed that the crystalinity degree of the inlaid polyester decreased,while acetic acid treatment made it increased slightly.The wearablity test indicated that the sericin protein had firmly grafted onto the polyester surface.The polyester exhibited improved wettability and antistatic property,as well as good crease elasticity.Softening treatment rendered the polyester good softness.
