Dyeing deep and vibrant colors in textiles often presents a unique challenge: maintaining impeccable colorfastness, particularly wet rubbing fastness. The intensity of dark black, scarlet red, or vivid turquoise blue can be diminished by color migration, leading to customer dissatisfaction. NINGBO INNO PHARMCHEM CO.,LTD. offers a solution with our Wet Rubbing Fastness Improver Agent SM-2020, a leading product among specialty chemicals for deep color dyeing.


SM-2020 is specifically formulated as a powerful wet rubbing fastness enhancer for sulfurized dyes and reactive dyes, addressing the notorious issue of wet crocking in dark shades on cellulose fibers. This advanced waterborne polyurethane polycation compound creates a robust barrier on the fiber surface, significantly improving wet rubbing fastness by 1-2 grades, often achieving a remarkable increase to over 3 grades. This capability is essential for ensuring that deep colors retain their vibrancy and integrity, even after repeated exposure to friction and moisture.


As a dedicated textile dyeing fastness chemicals manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical need for stability and reliability in high-end textile production. Our SM-2020 not only excels in improving colorfastness but also ensures that the fabric's original soft handle, shade, and fastness to sunlight remain unaffected. This comprehensive performance makes it an ideal choice for textile companies aiming to enhance the quality and marketability of their deep-colored fabrics. When you purchase deep color enhancer from us, you invest in superior textile quality.


The application of SM-2020 is flexible, suitable for both padding and dipping processes, allowing for easy integration into existing textile finishing lines. Its compatibility with cationic and non-ionic products, combined with excellent acid resistance and stability, provides a robust and reliable solution for various dyeing scenarios. With SM-2020, NINGBO INNO PHARMCHEM CO.,LTD. empowers manufacturers to confidently produce deep-colored textiles that stand the test of time and usage, solidifying their reputation for quality and innovation.
