In the complex landscape of textile processing, achieving optimal quality and efficiency in cotton fabric treatment relies heavily on the effectiveness of chemical auxiliaries. Among the critical steps, mercerization and alkali desizing stand out for their impact on fabric properties like luster, strength, dye uptake, and overall handle. However, these processes often involve high concentrations of sodium hydroxide, presenting a significant challenge for standard wetting and penetrating agents. Traditional penetrants can lose their effectiveness, failing to ensure uniform wetting and complete alkali penetration, leading to inconsistent results and compromised fabric quality.

Recognizing this challenge, NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer an advanced High Alkali Resistant Penetrant designed specifically for the demanding conditions of cotton mercerizing and alkali desizing. This specialized liquid auxiliary is formulated to maintain exceptional performance even in highly concentrated sodium hydroxide solutions, such as those reaching 30°Be/54°Tw.

The key to the product's efficacy lies in its unique composition, primarily a polyphenol anionic surfactant. This specific chemistry provides inherent stability and functionality in strongly alkaline environments where many other surfactants would fail. By significantly lowering the surface tension of the alkali bath, the penetrant allows for rapid and uniform saturation of the cotton fibers. This uniform penetration is crucial for maximizing the benefits of both mercerization and desizing processes.

During mercerization, uniform alkali absorption across the fabric width and thickness is essential for achieving consistent swelling of the cotton fibers. This swelling rearranges the cellulose molecules, leading to increased tensile strength, improved dimensional stability, enhanced luster, and a higher affinity for dyes. Without effective penetration, mercerized effects can be patchy, resulting in uneven dyeing and reduced fabric value.

Similarly, in alkali desizing, effective penetration and wetting are necessary for the complete removal of sizing agents applied to the warp yarns before weaving. Residual sizing can interfere with subsequent dyeing and finishing processes. The High Alkali Resistant Penetrant ensures the alkali solution can efficiently reach and solubilize or degrade the sizing agents, allowing them to be washed away effectively. This results in cleaner fabric, better preparation for subsequent steps, and improved overall process reliability.

NINGBO INNO PHARMCHEM CO.,LTD.'s penetrant is supplied as a yellow transparent liquid, making it easy to handle and incorporate into existing process formulations. Its physical and chemical indicators demonstrate its quality and consistency: a pH typically ranging from 6.5 to 7.0, a solid content between 61% and 65%, anionic ionicity, and a density of 1.05 to 1.15. These specifications ensure reproducible performance batch after batch.

Dosage recommendations vary depending on the fabric's preparation state to optimize performance while managing costs. For original (grey) fabrics, a dosage of 4.0 to 8.0 g/L is typically recommended due to the presence of natural impurities and sizing. For refining fabrics, where some initial preparation has occurred, a lower dosage of 2.0 to 4.0 g/L is often sufficient. For bleached fabrics, which are already highly prepared, an even lower dosage of 1.0 to 2.0 g/L is generally effective. Precise dosage should always be determined through laboratory testing or mill trials based on the specific process parameters and desired outcome.

Using a high-performance penetrant like the one offered by NINGBO INNO PHARMCHEM CO.,LTD. translates into tangible benefits for textile manufacturers. It improves process efficiency by ensuring faster and more uniform treatment, potentially reducing processing time and energy consumption. It enhances fabric quality by guaranteeing consistent mercerization and desizing effects, leading to fewer rejects and reworks. Furthermore, its reliability in high alkali conditions minimizes process variability, contributing to more stable and predictable production.

Proper handling and storage are important for maintaining the product's quality. The recommended shelf life is 12 months when stored in a dry and ventilated area. As with all industrial chemicals, appropriate safety precautions should be taken. In case of accidental splash into eyes or skin, rinse immediately with plenty of water.
