NINGBO INNO PHARMCHEM CO.,LTD. supplies Anhydrous Sodium Sulfate at a purity level of 99%, a specification that is particularly critical for its role in the production of synthetic fibers. This high-grade chemical is a fundamental component that significantly influences the quality and characteristics of the final fiber products.

In the manufacturing of synthetic fibers, such as rayon or viscose, anhydrous sodium sulfate serves as an essential 'salting-out' agent. This process is vital in the regeneration of cellulose from a viscous solution (like viscose). The sodium sulfate helps to decrease the solubility of cellulose xanthate in the spinning bath, facilitating its precipitation and transformation into continuous filaments. The purity of the sodium sulfate is paramount here; impurities can interfere with the coagulation process, leading to uneven fiber formation, reduced tensile strength, and inconsistent dyeing properties. By using 99% pure anhydrous sodium sulfate from NINGBO INNO PHARMCHEM CO.,LTD., manufacturers can ensure a smooth and efficient spinning process, yielding high-quality synthetic fibers that meet the stringent demands of the textile industry. This makes our product an indispensable 'synthetic fiber' raw material for producing textiles with desired strength, texture, and appearance.
