In today's discerning market, consumers demand textiles that not only look good but also last. High-performance fabric color durability is no longer a luxury but a necessity, especially for garments subjected to frequent washing and wear. Achieving this durability, particularly concerning wet rubbing fastness, requires advanced chemical solutions that can effectively lock in colors on various fiber types, especially cellulose.


NINGBO INNO PHARMCHEM CO.,LTD. addresses this critical need with its innovative Wet Rubbing Fastness Improver Agent SM-2020. This product is a cutting-edge Textile Auxiliary designed to significantly enhance wet rubbing fastness for cellulose fibers. As a waterborne polyurethane polycation compound, SM-2020 forms a strong, protective film on the fiber surface and undergoes cross-linking reactions with the active groups of cellulose. This dual-action mechanism ensures that direct, reactive, and sulfurized dyes are firmly anchored, preventing color transfer and fading even under wet friction.


The impact of SM-2020 on fabric quality is profound. It consistently improves wet rubbing fastness by 1-2 grades, allowing textiles, even those with challenging deep colors like dark black or bright red, to achieve fastness levels greater than 3. What sets this polyurethane wet rubbing fastness enhancer apart is its ability to deliver superior durability without compromising other crucial fabric properties. It ensures the fastness of the dyed fabric will not be damaged, and the textile retains its original soft handfeel and vibrant shade.


As a trusted supplier of textile wet fastness chemicals, NINGBO INNO PHARMCHEM CO.,LTD. offers SM-2020 as an eco-friendly wet rubbing agent for deep colors, adhering to stringent environmental standards.
