Dyeing polyester-cotton blended fabrics presents a unique set of challenges due to the differing dyeing properties of each fiber type. Achieving uniform color depth and preventing cross-staining requires precise techniques and specialized chemical auxiliaries. The goal is to ensure the cotton component takes up reactive dyes, while the polyester remains unaffected, or vice versa for disperse dyes.


NINGBO INNO PHARMCHEM CO.,LTD. offers a solution specifically designed to overcome these hurdles: Polyester Reserving Agent SD-3717. This innovative textile auxiliary functions as a highly effective polyester-cotton blended fabric anti-dyeing agent. Its primary mechanism involves creating a strong resist effect on polyester fibers, ensuring that water-soluble dyes, typically used for cotton, do not bleed onto or stain the polyester component.


Utilizing SD-3717 in your dyeing process means achieving cleaner, more vibrant results. The agent's nonionic nature and strong affinity to polyester fiber allow for seamless integration into existing dyeing protocols, simplifying what can often be a complex multi-stage process. Furthermore, for those seeking a superior textile auxiliary for polyester whitening, SD-3717 also plays a crucial role in enhancing the brightness of polyester in blends, resulting in a cleaner overall fabric appearance.


The application of SD-3717 helps optimize dye utilization and reduces the need for extensive post-dyeing clearing, saving both time and resources. As a trusted polyester fiber dyeing auxiliary supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures that this product is not only highly effective but also environmentally responsible, free from harmful heavy metals and AEPO. This makes it an ideal choice for manufacturers committed to both quality and sustainability.
