Neutral Protease

Neutral Protease

 Specialized neutral protease enzyme formulated for gentle yet effective bio-polishing of wool and protein fibers. Operating at neutral pH (6.0-8.0), this enzyme enhances fabric softness, reduces pilling, and improves drape while preserving fiber integrity. Ideal for luxury textile finishing, premium garment processing, and high-quality wool treatment applications.

Key Selling Points


Solves Premium Fiber Processing Challenges:


Our neutral protease addresses the delicate balance required in protein fiber treatment – effective bio-polishing without fiber damage. It gently removes fiber protrusions and surface fuzz, creating smooth, soft fabric with enhanced luster. The enzyme specifically targets protein structures while being gentle enough for delicate wool and silk, preventing the felting and shrinkage issues common with harsh chemical treatments.


Ideal Applications:


Wool fabric bio-polishing and anti-pilling treatment

Silk degumming and softening

Cashmere and mohair finishing

Premium wool garment processing

Luxury home textile finishing (wool blankets, throws)

Anti-felting treatment for washable wool

Fashion fabric enhancement


What Makes Our Product Stand Out:


Our neutral protease is specifically engineered for protein fibers with optimal activity at pH 6.0-8.0, the safe range for wool and silk. Unlike alkaline proteases that can damage fibers, our enzyme works gently at the fiber surface, removing only loose protein fibers while maintaining yarn strength. The formulation includes wool-protective agents that prevent excessive degradation.

Product Knowledge


What is Neutral Protease for Wool Treatment?


Neutral protease is a bio-catalyst that breaks down protein bonds, specifically engineered to operate at neutral pH levels (6.0-8.0) where wool and silk fibers remain stable. Unlike alkaline proteases that can damage protein fibers, neutral protease gently hydrolyzes only the protruding fiber ends and surface proteins that cause pilling and rough texture. The enzyme contains specific amino acid sequences that recognize and cleave peptide bonds in keratin (wool) and fibroin (silk) proteins, creating a smooth, polished surface. This bio-polishing process mimics natural enzymatic degradation but in a controlled, beneficial manner.


What are the Applications of Neutral Protease?


Neutral protease is essential in premium wool processing where quality and fiber protection are paramount. In fashion wool fabric finishing, it creates the soft, luxurious hand feel demanded by high-end markets while reducing pilling for improved garment longevity. For washable wool production, the enzyme provides anti-felting treatment by removing scales from fiber surfaces, enabling machine washing without shrinkage. In silk processing, it assists with degumming – removing sericin protein while maintaining fibroin fiber strength, resulting in softer, more lustrous silk. The enzyme is also used in cashmere and mohair finishing, where preserving the natural softness while improving consistency is crucial.
