Collagen-Modified Regenerated Cellulose Fiber

The Future of Sustainable Textiles: Collagen-Modified Regenerated Cellulose Fiber

In an era marked by environmental crises and growing demand for sustainable materials, collagen-modified regenerated cellulose fiber emerges as a groundbreaking innovation in the textile industry. Developed by Shandong Dachuan New Materials Co., Ltd., this bio-based fiber combines the natural advantages of collagen with eco-friendly manufacturing processes, offering a versatile solution for modern textile applications.

What is Collagen-Modified Regenerated Cellulose Fiber?

This fiber is a composite material created by cross-linking Type I collagen (extracted from bovine leather) with cellulose derived from wood pulp. The production process involves dissolving collagen-rich cowhide raw materials, blending them with cellulose, and forming fibers through wet spinning and coagulation. The result is a biodegradable, high-performance textile material that retains the functional benefits of both collagen and cellulose.

Key Advantages of Collagen Fiber

1. Natural Antibacterial & Deodorizing Properties

• Collagen’s fat-soluble protein factors inhibit bacterial growth (e.g., 99% inhibition rates against Staphylococcus aureus and Escherichia coli).
• Its mesh-like structure traps bacteria and limits nutrient access, reducing odor-causing microbial activity.

1. Mold & Fungal Resistance

• Achieves Grade 0 mold resistance (highest level), preventing damage to textiles and extending product lifespan.
• Disrupts fungal cell structures, lowering risks of skin infections.

1. Superior Moisture Management

• 12.13% moisture regain rate outperforms cotton and linen, ensuring quick sweat absorption and rapid drying.
• Ideal for sportswear and bedding, where breathability and comfort are critical.

1. Skin-Friendly & Hypoallergenic

• Type I collagen closely resembles human epidermal components, offering moisturizing effects and reducing skin irritation.
• Complies with EU ROHS and REACH standards, free from harmful additives like formaldehyde or heavy metals.

1. Sustainability & Circular Economy

• Derived from renewable bovine leather waste, fully biodegradable, and produced via a closed-loop process.
• Certified by RCS (Recycled Claim Standard) and meets GB/T 18885-2020 eco-textile requirements.
