High functional PET sericin composite fabric

摘要

Though poly(ethyleneteraphthalate)(PET) fabrics have high initial modulus, outstanding creasability and wash-well character, but its hydrophilicity and biocompatibility are very poor. In this paper, the PET fabric was encased sucrose ester at high pressure and high temperature to endue it enough hydroxyl to grafting protein. The sericin was grafted on PET fabric by sucrose eater glycidyl ether (SEGE). The FT-IR spectra showed that sericin was grafted on PET fabric, and the structure of sericin was random coil conformation. X-ray diffraction spectra showed the structure of PET fiber did not changed. DSC showed the thermostability increased a little. After the PET fabric grafted with sericin, the hydrophilicity of PET sericin composite fabric was improved greatly, the cockle elasticity kept well, and the broken strength in creased a little. Certainly, the whiteness and air permeability decreased a little. The PET sericin composite fabric was high functional.
