Processing cotton and blended fabrics presents unique challenges in textile manufacturing, from managing natural impurities to ensuring consistent dye uptake. To achieve high-quality results, the use of specialized additives is indispensable. NINGBO INNO PHARMCHEM CO.,LTD. offers RG-SPN, a versatile chelating dispersant that serves as an essential component for optimizing cotton and blended fabric processing at various stages.

Our RG-SPN, an advanced acrylic polymer chelating agent, plays a crucial role in the pretreatment of cotton and its blends. It has an excellent dispersing effect on impurities such as waxes, pectin substances, and hard water precipitates contained in raw cotton. This ensures a cleaner substrate for dyeing, significantly improving the fabric's water absorption and whiteness. As a reliable chelating dispersant manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. ensures RG-SPN's formulation effectively prepares fabrics for subsequent treatments.

During the dyeing phase, especially for polyester/cotton blends, RG-SPN acts as a vital hard water dyeing cotton additive. It prevents wax and pectin impurities, released from cotton during dyeing, from forming problematic precipitates with dyes. This is particularly important in cheese dyeing to prevent blockage of bath circulation and deposition on yarn. Furthermore, for reactive dye dyeing, RG-SPN prevents hydrolyzed reactive dyes from forming difficult-to-remove calcium salts, contributing to better color fastness.

Beyond dyeing, RG-SPN is highly suitable for post-soaping operations after reactive dyeing and printing. Its excellent diffusion properties ensure that floating colors are effectively dispersed in the soap bath and not redeposited on the fabric surface, dramatically improving washing and rubbing fastness.
