Enzymatic Degumming

Technological Principles

Enzymatic degumming harnesses the power of natural enzymes, specifically proteases, to break down the sericin protein. These enzymes catalyze the hydrolysis of peptide bonds within the sericin structure, effectively dissolving it without harming the delicate silk fibers. This process is carried out under controlled conditions of temperature, pH, and enzyme concentration to ensure optimal performance and fiber protection.

• Gentle on Silk: Our enzymatic degumming process is exceptionally gentle on silk fibers, preserving their natural strength, luster, and elasticity.
• Enhanced Silk Quality: By effectively removing sericin, our process improves the drape, softness, and dye uptake of the silk, resulting in higher quality fabrics.
• Reduced Water Consumption: Compared to traditional methods, enzymatic degumming significantly reduces water consumption, contributing to water conservation efforts.
• Lower Energy Requirements: The process operates at lower temperatures and requires less energy than conventional degumming, promoting energy efficiency.
• Minimized Waste: Enzymatic degumming generates less wastewater and reduces the reliance on harsh chemicals, minimizing environmental pollution.
