Reactive and sulfur dyes are widely used in the textile industry for their vibrant colors and good overall fastness properties, particularly on cellulose fibers like cotton. However, one common challenge with these dyes, especially in deep shades, is achieving excellent wet rubbing fastness. Poor fixation can lead to color bleeding and staining of other garments, diminishing the perceived quality of the textile. Addressing this requires continuous Reactive & Sulfur Dye Fixation Innovations in chemical auxiliaries.


NINGBO INNO PHARMCHEM CO.,LTD. provides a breakthrough solution with its Wet Rubbing Fastness Improver Agent SM-2020. This product is a sophisticated waterborne polyurethane polycation compound specifically engineered to enhance wet rubbing for reactive dyes and sulfurized dyes on cellulose fibers. Its unique mechanism involves cross-linking with the active groups on the fiber, forming a durable film that effectively anchors the dye. This ensures that even the most challenging dark black, bright red, or turquoise blue shades achieve significantly improved fastness, often by 1-2 grades.


SM-2020 is more than just a performance enhancer; it's a testament to responsible chemical innovation. As an eco-friendly wet rubbing agent for deep colors, it complies with EU Standard 100, being free from APEO, formaldehyde, and heavy metals.
