In the competitive textile market, the quality of whites and the precision of dye resists are crucial differentiating factors. Achieving a brilliant, lasting white on polyester or ensuring that specific areas of a blended fabric remain undyed while others take color requires highly specialized chemical agents. These agents are fundamental for both aesthetic appeal and functional performance.


NINGBO INNO PHARMCHEM CO.,LTD. provides cutting-edge solutions to meet these demands, including our acclaimed Polyester Reserving Agent SD-3717. This product serves as an exceptional textile auxiliary for polyester whitening, enhancing the brightness and purity of white polyester fibers. Simultaneously, it acts as a powerful dye resist, specifically designed for polyester components in blended fabrics, such as polyester-cotton.


When dyeing polyester-cotton blends, the challenge often lies in preventing the reactive dyes used for cotton from staining the polyester. Polyester Reserving Agent SD-3717 excels as a polyester fiber dyeing auxiliary SD-3717 by creating a strong barrier on the polyester surface, effectively reserving it from water-soluble dyes. This ensures that the cotton absorbs the dye as intended, while the polyester remains pristine, leading to clear, defined patterns and vibrant contrasts.

This makes it a responsible choice for manufacturers prioritizing both high-quality output and environmental safety.
