The objective of this study was to investigate the dye absorption properties of chitosan/nano-silver composite fiber (CSF) and their blended knit fabrics (CSK) compare with cotton fiber (CMF) and their knit fabrics (CMK). The dye absorption of CSF and CSK showed relatively high level compared to that of the CMF and CMK, but K/S value of CMK was higher than that of CSK. In the case of CSF and CSK, most of dyes were exhausted within 20 minutes after completing the dyeing process regardless of dye reactive groups and affinities, and there were no significant decreases in the washing and rubbing fastness compared with CMK.
