@@ In this study, we used citric acid (CA) as a crosslinking agent, mixed with polyhexamethylene biguanide, to perform a pad-dry-cure treatment on wool fabrics to study its antimicrobial effects and physical properties. The surface characteristic and the structure of wool fabric were investigated by means of scanning electron microscopy (SEM). Fourier transform infrared spectroscopy (FTIR) was employed to study the crosslinking mechanism of the treated fabric.
