Abstract

The natural dyeing of silk fabric with Scutellaria baicalensis extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Scutellaria baicalensis extract were 90% v/v, <TEX>$90^{\circ}C$</TEX>, 60 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods.
