The textile industry utilizes a variety of enzymes to achieve different finishing effects, with cellulases being among the most important. Broadly, cellulases are categorized based on their optimal pH range: acid cellulases and neutral cellulases. NINGBO INNO PHARMCHEM CO.,LTD. offers both types, understanding that each serves distinct purposes. However, for many modern textile finishing applications, neutral cellulase enzymes present distinct advantages, particularly concerning fabric integrity and color preservation. This comparison aims to illuminate why neutral cellulase is often the preferred choice.

Acid cellulases function best in an acidic pH environment, typically between 4.5 and 5.5. They are highly effective for vigorous treatments like denim washing, where aggressive abrasion and a pronounced 'stone-washed' look are desired. Their strength lies in their ability to rapidly degrade cellulose, leading to significant fuzz removal and abrasion. However, this aggressive action can also lead to undesirable consequences such as increased fabric strength loss, potential damage to elastic fibers in blends, and significant color fading, especially on dyed fabrics.

In contrast, neutral cellulase enzymes operate optimally in a near-neutral pH range (5.5-7.5). This milder processing condition offers several key benefits for cellulosic fabrics. Firstly, neutral cellulases provide excellent biopolishing effects – smoothing the fabric surface, reducing pilling, and enhancing luster – with significantly less damage to the fabric's strength. This is crucial for maintaining the garment's durability and ensuring customer satisfaction. Secondly, they exhibit superior color retention. The gentle action minimizes the loss of dye, preserving the vibrancy and intended shade of the fabric, which is paramount for fashion items where color is a defining characteristic.

The choice between acid and neutral cellulase often depends on the specific application. For denim finishing requiring extreme abrasion, acid cellulases might still be employed. However, for general biopolishing, garment softening, and applications where color fastness and fabric integrity are priorities, neutral cellulases are the superior option. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed technical data and support to help manufacturers select the most appropriate enzyme. Understanding the cellulase enzyme mechanism for each type allows for informed decision-making.

When aiming for a premium finish that balances surface refinement with fabric health, neutral cellulase enzymes from NINGBO INNO PHARMCHEM CO.,LTD. are the clear choice. Their efficacy in enhancing fabric feel, appearance, and longevity, all while operating under gentle conditions, makes them an indispensable tool for sustainable and high-quality textile manufacturing. The careful consideration of the cellulase enzyme dosage for fabric and processing conditions ensures optimal performance regardless of the enzyme type chosen.
