Lyocell Dissolving Pulp Activation Enzyme
This product is a specialized enzymatic preparation designed for the activation of cellulose fibers in Lyocell dissolving pulp systems. It is formulated to enhance fiber swelling, improve solvent penetration, and optimize the dissolution behavior of cellulose during Lyocell fiber production.
By selectively acting on the amorphous regions and fiber surfaces, the enzyme improves pulp reactivity without excessive degradation of cellulose chains. This controlled activation contributes to improved process stability, higher dissolution efficiency, and enhanced quality of regenerated cellulose fibers.
产品形态
- 颜色： Yellow to brown
- Physical State: 液体
- 气味： 轻微的发酵气味
- 可溶性： 易溶于水
Due to variations in raw materials and production cycles, slight differences in color may occur. These variations do not affect product performance.
建议的运行条件
- 温度范围： 35–65°C
- 最佳pH范围： 6.0–7.0
The enzyme shows stable activity under near-neutral pH conditions, making it suitable for Lyocell pulp pretreatment processes that require controlled and predictable fiber activation.
Dosage Guidance
Typical addition level ranges from 0.05% to 0.5% based on dry pulp weight. An optimal dosage of approximately 0.1% is commonly used, though the exact amount should be determined according to pulp characteristics and specific process conditions.
申请方式
During Lyocell fiber production, dissolving pulp must be completely dissolved in N-methylmorpholine N-oxide (NMMO). Prior to dissolution, the use of a cellulase enzyme to activate the pulp can improve fiber swelling and increase the cellulose content in the spinning dope.
The addition method can be selected as either batch addition or continuous addition according to specific process conditions.
Typical reaction time ranges from 45 to 90 minutes, with a bath ratio of 1:7 to 1:25.
Actual application conditions should be optimized based on the specific production process. After completion of the enzymatic reaction, adjusting the pH above 10 and/or increasing the temperature above 90°C and maintaining for at least 15 minutes will effectively terminate enzyme activity.
Performance Benefits
- Activates dissolving pulp and improves fiber swelling behavior
- Reduces cellulose aggregation and enhances dissolution efficiency
- Improves uniformity of cellulose solutions
- Contributes to higher-quality Lyocell fibers
储存条件
Store the product in a sealed container in a cool, dry environment. Avoid direct sunlight. Lower storage temperatures help maintain enzyme activity and extend shelf life.
