The performance of flos caryophyllata extract on black dyeing and UV resistance

Dyed the silk with flos caryophyllata extract using different mordant dyeing methods, and the results show it will get purer black and better K/S value of dyed silk, if using ferrous ion post-mordanting. Optimize the process of the ferrous ion mordanting, and get the best condition was 10% (o.w.f.) of the mordant concentrations at 80 degrees C for 50min. Using the mixture of flos caryophyllata and acutissima shell, the properties UV resistance was greatly enhanced.
