| Abstract: | The silkworm produces sericin, a sticky protein material that firmly keeps the fibroin strands of its cocoons together. The structural integrity of the cocoon, as well as its strength and stiffness, are greatly enhanced by the fibroin and sericin. To achieve the desired silk qualities for potential uses, such as shininess, stretchability, dye capacity, and durability, extracting as much sericin as possible from the fiber during the degumming process is essential. Our research described in this paper introduced a novel method for modifying the surface of Tussar silk using the aqueous extract of Acacia auriculiformis, derived from natural sources, which is not only environmentally friendly but also a sustainable degumming agent. The effects of variations in Acacia auriculiformis concentration, degumming duration, and solution temperature on the surface modification of the silk fibroin were examined. The data was evaluated utilizing weight loss and degumming percentages. The surface morphology of the silk samples was analyzed using scanning electron microscopy (SEM) image analysis. Comparison with hederagenin, a product of saponin hydrolysis, was conducted to elucidate the process by which saponin degrades sericin. Our current degumming process using Acacia auriculiformis, provides 22 to 24.8% of weight loss from silk fiber in 15 min which is sufficient to degrade most of the sericin. This study evaluated the efficacy of Acacia auriculiformis as a degumming agent in comparison to currently used sodium carbonate. The examination was conducted utilizing SEM, Thermogravimetric analysis, and Differential Scanning Calorimetry methodologies. [ABSTRACT FROM AUTHOR] |
