Stability of Salvia miltiorrhiza Bge Extract and its Application on Silk
The stability of Salvia miltiorrhiza Bge (SMB) extract and its dyeing and ultraviolet protective properties on silk were investigated. The results indicated that SMB extract was stable at acidic conditions and stable to heat and ultraviolet light. The building-up and UV-protective properties of SMB extract for silk were good and can be enhanced by mordanting with ferrous and ferric sulfate and copper sulfate. The light fastness rating was improved using ferric sulfate, while the washing and light fastness properties were worsen using ferrous sulfate.
