Neutral Cellulase NEF®2100 for Efficient Knitwear Bio- Polishing

By Baico Biotech 丨 Textile Enzyme 丨 BIO-SCOURINGENZYME 丨 BBT-HK-Kathleen

The loop structure of knitted fabric makes it inherently prone to surface fuzz and pilling caused by friction during processing. These microfibers and pilling not compromise the fabric’s appearance but hinder the uniform penetration of dyestuff, leading to uneven dyeing result and reducing color brilliance. The primary purpose of Bio-polishing prior to dyeing is to eliminate these negative factors at the source, ensuring a clean and smooth substrate for subsequent coloration.

Baico Biotech BBT Enzymes are textile enzyme and household detergent enzyme manufacture in China, has developed NEF®2100 — a granule neutral cellulase enzyme specifically designed for knitwear bio-polishing before dyeing. Leveraging its proprietary multi-layer coating technology, NEF®2100 offers an extended shelf life of two years while maintaining consistently high enzyme activity throughout storage.

In the textile bio-polishing process, neutral cellulase NEF®2100 efficiently decomposes surface fuzz and pilling at 55℃ under neutral condition for 60 minutes, and can be integrated with dyeing in a one-bath process to simplify production operations. The result is a cleaner, brighter, and smoother fabric surface that allows dyestuff to penetrate deeply and evenly into fiber interior, delivering superior dyeing evenness and enhanced color fastness. In addition, the anti-pilling effect achieved through NEF®2100 treatment is long-lasting, maintaining excellent performance even after multiple wash cycles.

Compared with conventional chemical polishing processes, NEF®2100 substantially reduces water, electricity, and steam consumption, while also lowering effluent treatment pressure. Moreover, the NEF®2100 is significantly gentler on fibers than acidic cellulase, selectively removing fiber fuzz and pilling while preserving the strength of fabric. It is an ideal choice for knitwear manufacturers.

In summary, NEF®2100 from Baico Biotech is more than just a bio- polishing enzyme — it is a comprehensive solution that enhances fabric quality, protects fiber strength, simplifies operations, and reduces effluent treatment pressure. With its proven stability, outstanding polishing efficiency, and gentle action,NEF®2100 empowers knitwear mills to consistently produce high- quality, competitive products while meeting the growing demand for sustainable textile processing.
