The use of natural plants for dyeing is a new green approach in the textile industry using eco-friendly, renewable, and non-toxic reductants for dyeing fabric. Recently, various templates have been reported to enhance the polymerization of natural phenols. In this paper, ferulic acid (FA) was synthesized using a new approach and arranged on poly(ethylene glycol) (PEG) templates using horseradish peroxide (HRP)-catalyzed oxidative polymerization. The polymerization mechanism was studied in detail using high-performance liquid chromatography-electrospray ionization mass spectrometry (HPLC-ESI-MS) analysis. In addition, the template effect of PEG on 13 natural phenols was also investigated. Upon analyzing the color depth, the K/S value of the silk fabric dyed using PEG as a template was significantly higher than that in the absence of PEG. The higher color depth of the poly(ferulic acid)/PEG-treated silk fabrics further validated the important role of PEG as a template. This study presents an environmentally friendly method for dyeing silk fabric under mild conditions and the polymerization mechanism. Compared to chemical polymerization reactions, this enzyme (HRP)-based synthesis is more environmentally friendly due to its milder reaction conditions. [ABSTRACT FROM AUTHOR] |
