Wool Protease – Anti-Felting & Anti-Pilling Enzyme for Wool Finishing
Wool Protease is a high-performance enzymatic solution specifically developed for the bio-finishing of wool and wool-blended fabrics. It offers a sustainable and gentle alternative to traditional chemical anti-felting agents, effectively improving the surface smoothness, softness, and whiteness of wool fibers while maintaining their natural resilience and elasticity. The product is designed for textile manufacturers seeking high-quality, eco-friendly wool finishing performance with minimal fiber damage.
Gambaran Keseluruhan Produk
Wool Protease contains a unique blend of silk fibroin-based proteolytic enzymes that act selectively on the wool fiber’s outer cuticle layer. During processing, the enzyme gently hydrolyzes and smooths the scale structure of the wool, reducing inter-fiber friction that causes felting shrinkage and pilling. Unlike harsh oxidative or chlorination methods, this biological treatment works under mild conditions and preserves the intrinsic beauty and strength of wool fibers.
The enzyme’s high purity and strong activity (100,000 U/mL) ensure consistent performance across a wide range of processing environments. It can be used in both batch and continuous systems, providing flexible application options for textile mills, knitwear processors, and wool finishing plants.
Key Benefits
- Anti-Felting Effect: Prevents entanglement and felting shrinkage during washing and mechanical agitation.
- Anti-Pilling Performance: Reduces fuzz formation and surface pilling, keeping fabrics smooth and new-looking.
- Enhanced Softness: Gives wool fabrics a softer, silkier hand feel and improved drape.
- Improved Whiteness and Luster: Enzymatic treatment enhances brightness and surface reflection for more vivid colors and clean whites.
- Mild and Eco-Friendly: Operates under gentle temperature and pH conditions, reducing energy use and wastewater pollution.
- Versatile Application: Suitable for pure wool, wool blends, and delicate knitwear.

Dos yang Disyorkan
Use 0.04–0.05% (on fabric weight) depending on fabric structure, wool type, and finishing process. Preliminary trials are recommended to determine optimal dosage and processing conditions.
Mechanism of Action
The Wool Protease acts selectively on the outer cuticle layer of wool fibers. It gently breaks peptide bonds within the scale structure, partially smoothing the surface and reducing fiber-to-fiber friction. This controlled enzymatic hydrolysis prevents felting and pilling while maintaining tensile strength and elasticity. The process produces a uniform, soft, and lustrous finish with improved dye uptake and color brightness.
Aplikasi
