The successful application of cellulase enzymes in textile finishing hinges on a precise understanding and control of various processing parameters. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to empowering textile manufacturers with the knowledge needed to achieve optimal results, whether for biopolishing, garment washing, or other enzymatic treatments. Key factors such as enzyme dosage, pH, temperature, liquor ratio, and inactivation methods play a critical role in determining the final fabric quality, efficiency, and cost-effectiveness of the process.

Enzyme Dosage: Determining the correct enzyme dosage is paramount. Overdosing can lead to excessive fiber degradation, strength loss, and poor color yield, while underdosing results in inadequate finishing effects. The typical recommendation for neutral cellulase in biopolishing is between 0.1% and 0.3% (o.w.f. – on weight of fabric). However, this can vary based on the specific enzyme product's activity, the fabric type (e.g., 100% cotton versus blends), the desired level of polishing, and the processing equipment used. Pilot tests are always recommended to fine-tune the dosage for specific applications.

pH Control: As discussed, neutral cellulases perform best within a pH range of 5.5 to 7.5. Maintaining this pH throughout the enzymatic reaction is crucial for consistent activity. Buffers are often employed to stabilize the pH. Deviations can significantly reduce enzyme efficiency or even lead to unwanted side reactions. NINGBO INNO PHARMCHEM CO.,LTD. provides enzymes formulated for excellent stability within their optimal pH range, but proactive monitoring and adjustment are still necessary.

Temperature Management: The optimal temperature for neutral cellulases is generally between 45°C and 55°C. Temperatures below this range will slow down the enzymatic reaction, requiring longer processing times. Conversely, excessively high temperatures can denature the enzyme, rendering it inactive. Careful temperature control, often managed through the heating and cooling systems of dyeing or washing machines, ensures the enzyme works at its peak performance. The cellulase enzyme mechanism is highly sensitive to thermal changes.

Liquor Ratio: The liquor ratio refers to the ratio of the volume of the treatment bath to the weight of the fabric. A standard liquor ratio for enzymatic treatments is typically between 1:5 and 1:15. An appropriate liquor ratio ensures adequate enzyme diffusion and contact with the fabric, facilitating uniform treatment. Insufficient liquor can lead to uneven results and reduced efficiency.

Inactivation: Once the desired finish is achieved, the enzyme must be inactivated to stop the reaction. This is typically done by increasing the temperature to above 70-80°C for 10-20 minutes or by adjusting the pH to highly acidic or alkaline conditions. Proper inactivation is key to preventing damage to the fabric after the intended enzymatic treatment. The effectiveness of the cellulase enzyme inactivation process directly impacts the final product quality.

By carefully managing these parameters, textile manufacturers can harness the full power of cellulase enzymes to achieve superior fabric finishes. NINGBO INNO PHARMCHEM CO.,LTD. offers not only high-quality enzymes but also the technical expertise to guide manufacturers in optimizing their processes for maximum efficiency and exceptional results.
