In this paper,the soybean protein / poly (ethylene terephthalate)PET composite fabric was obtained and its wearability was mainly studied. It is found that the moisture regain, water absorption, air permeability and moisture permeability of soybean protein PET composite fabric were improved greatly. In addition, the whiteness and elastic wrinkle recovery angle kept well, and the stiffness increased incredibly. Therefore, soybean protein being grafted on PET fabric surface not only improved the biocompatibility, but also the wearability.

The erosion behaviour of knitted fabric-reinforced glass fibre (GF)/poly(ethylene terephthalate) (PET)-composites was investigated by solid particle impact with irregularly shaped corundum particles. Angular (30° to 90°) and morphological (matrix crystallinity) dependencies of the wear rate were studied. The specific erosion wear rate was recorded and scanning electron microscopy (SEM) investigations have been performed to describe the wear mechanisms. In general, high erosive wear rates were detected. A maximum erosion rate was found at impacting angles of 60° for all investigated composites. At normal impact (90°) lower wear rates were observed which depended also on the matrix crystallinity. The erosion wear rate increased with increasing crystallinity, knit stretching and annealing (crystallinity change by cold crystallisation). No influence was found for the erosion direction when tests were performed in wale (WD) and course (CD) direction of the knit, respectively. SEM micrographs supported the semi-brittle wear behaviour showing brittle fracture of the glass fibres and the ductile deformation of the PET matrix.

The absorption behavior of water in poly (ethylene terephthalate)-poly (ethylene glycol) (PETG) block copolymers was investigated using the time-resolved FTIR-ATR (Fourier Transform Infrared Attenuated Total Reflection) spectra. The data was analyzed by two-dimensional correlation spectra (2D-COS), which provided relevant and complementary information on the absorption mechanism and the molecular interactions formed (H-bonding). It was found that there were two kinds of water molecules, named bound water and free water in absorption process. The delicate relationship between dynamic water absorption behavior and the morphology resulting from phase separation was also discussed. Furthermore, two-dimensional correlation analyses revealed that in the absorption process, water first diffuses into the continuous soft-rich PEG phase and then into the hard-rich PET domains, forming hydrogen bonds with-O-groups prior to that of free volume.
