The post-dyeing treatment, particularly soaping, is crucial for the final quality and fastness properties of textiles dyed with reactive dyes. Ensuring the complete removal of unfixed and hydrolyzed dyes is essential to prevent back-staining, dulling, and poor wash fastness. NINGBO INNO PHARMCHEM CO.,LTD. presents RG-SPN, an advanced and eco-friendly soaping agent for reactive dyes, designed to optimize this critical stage.


RG-SPN, an anionic chelating dispersant based on acrylic copolymers, stands out for its exceptional efficacy in removing hydrolyzed dye and floating color. This action is vital in reactive dyeing processes, as it secures the brilliance and clarity of the final color and significantly improves the fabric's overall wash and rub fastness. Its superior performance helps achieve the highest standards of fabric quality, making it a highly sought-after solution for cotton treatment and cellulose fiber processing.


What sets RG-SPN apart is its dual functionality. Besides being a potent soaping agent, it also acts as a powerful dispersant, preventing any removed impurities or dyes from redepositing onto the fabric surface. This ensures a clean and pristine finish, free from spots or dullness. Furthermore, its 'no foam' characteristic enhances operational efficiency, reducing processing time and chemical consumption, contributing to more sustainable textile practices.


In an era where environmental responsibility is paramount, NINGBO INNO PHARMCHEM CO.,LTD. offers RG-SPN as a solution that aligns with eco-friendly textile auxiliary principles. It delivers powerful cleaning action without compromising on safety or environmental impact.
