  • This study examines the dyeability, light fastness, washing fastness, and antibacterial activity of chitosan and nano silver composite knit fabrics dyed with extracted solution from Chrysanthemum Indicum Linn. The results show that ${\Delta}E$ values of chitosan and nano silver composite knit fabrics were higher than cotton 100% knit fabrics in dyed condition with extracted solution from Chrysanthemum Indicum Linn, and mordant treatments influenced the chrominance change. Chrysanthemum indicum Linn confirmed that this could be a polygenetic colors. ${\Delta}E$ values of post-mordant treatments knit fabrics were higher than pre-mordant treatments knit fabrics in dyed condition with extracted solution from Chrysanthemum Indicum Linn., and mordant treatments method influenced the chrominance change. The dyeability of chitosan and nano silver composite knit fabrics was increased by mordant treatment. The fastness of the chitosan and nano silver composite knit fabrics was better than cotton 100% knit fabrics. In the result of antibacterial activity, the bacterial reduction rate of chitosan and nano silver composite knit fabrics was 99.9% to Staphylococcus aureus and Klebsiella pneumoniae.

  • This study examines the dyeability, light fastness, washing fastness, and the antibacterial activity of chitosan and nano silver composite non-woven fabrics dyed with an extracted solution from Chrysanthemum Indicum Linn. The results show that an increase in the chitosan and nano silver percentage resulted in an increase in the $a^*$ values and $b^*$ values; however, the $L^*$ values decreased in the undyed condition. ${\Delta}E$ values of chitosan and nano silver composite non-woven fabrics were higher than cotton 100% non-woven fabrics in the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, and mordant treatments influenced the chrominance change. In the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, an increase in the percentage of chitosan and nano silver resulted in an increase of the K/S values. The dyeability of chitosan and nano silver composite non-woven fabrics increased by mordant treatments. The light fastness and washing fastness of the mordanted non-woven fabrics were better than the non-mordanted. For the antibacterial activity, the bacterial reduction rate of chitosan and nano silver composite non-woven fabrics was 99.9% to Staphylococcus aureus and Klebsiella pneumoniae.
