Developed functionalization of wool fabric with extracts of Lycium ruthenicum Murray and potential application in healthy care textiles.

Abstract To develop healthy care textiles, Lycium ruthenicum Murray (abbreviated as LRM in the following) extracts were prepared in both different media and characterized, respectively for the functionalizing of wool fabric by an exhaustion dyeing process. The antimicrobial and antioxidant activities of both LRM dyed wool fabric were then investigated and compared. Enhanced effect of Fe ions as the post mordants on functionalities and durability of the dyed fabrics was also examined. The results indicated that LRM ethanol extract was found to contain more anthocyanins than LRM water extract. LRM dyed wool fabric showed antimicrobial and antioxidant activities. Increasing color strength could enhance their functionalities. Treatment of Fe ions, especially Fe3+ led to the durable functionalities. Compared with the dyed wool fabric with Lycium barbarum L. extract, LRM dyed wool fabric exhibited strong functionalities. Graphical abstract Image 1 Highlights • Lycium ruthenicum Murray fruits were extracted by ethanol and water. • Their extracts were used for dyeing of wool fabric. • Dyed fabric exhibited antimicrobial and antioxidant activities. • Increasing color strength enhanced their functionalities. • Fe ions treating led to the durable functionalities.
