Reactive and sulfur dyes are widely used in the textile industry for their vibrant colors and good wash fastness on cellulose fibers. However, achieving excellent wet rubbing fastness with these dyes, especially in deep shades, can be challenging. Inadequate dye fixation often leads to color transfer, diminishing the fabric's quality and customer satisfaction. This highlights the critical need for innovative agents that specifically target and enhance the fixation of these dye types.


NINGBO INNO PHARMCHEM CO.,LTD. specializes in developing advanced chemical auxiliaries that address these precise challenges. Our Wet Rubbing Fastness Improver Agent SM-2020 is a prime example of our commitment to innovation. This waterborne polyurethane polycation compound is uniquely formulated to provide an excellent effect of improving wet rubbing fastness specifically for reactive and sulfur dyes when used on cellulose fibers. It works by creating strong bonds with the active groups on the fiber surface, effectively anchoring the dye molecules.


The benefits of using such an innovative dye auxiliary are manifold. Not only does it significantly improve the wet rubbing fastness by 1-2 grades (often reaching more than 3 grades), but it also ensures that the fastness to sunlight is unaffected, and the fabric retains a soft handle. This comprehensive approach means textile manufacturers can achieve brilliant, durable colors without compromising the fabric’s tactile properties or overall quality. Furthermore, SM-2020 is an APEO-free product, reflecting our dedication to providing environmentally responsible solutions that comply with global standards.
