The Dyeability and Antibacterial.Deodorization Activity of Silk Fabrics by Gromwell Extracts

Silk fabrics were dyed with Gromwell extracts after mordanted with various mordants and their dyeability, antibacterial.deodorization activity, fastness and change of surface color were investigated. Silk fabrics were mordanted at $60^\circ{C}$ for 30 minutes and subsequently dyed at $40^\circ{C}$ for 30 minutes. The dye-uptake of silk fabrics increased with the concentration of Gromwell extracts and mordants. Surface color of silk fabrics changed differently according to the type of mordants used. Antibacterial and deodorization activities of silk fabrics dyed with Gromwell extracts were good. Cu mordant was more effective for deodorization activity. Dyed silk fabrics showed poor light fastness but good dry-cleaning and perspiration fastness.
