Denim and dark-colored fabrics, while popular for their rich aesthetic, often pose significant challenges in achieving satisfactory wet rubbing fastness. The tendency for dye transfer, especially during wear and washing, can lead to consumer dissatisfaction and product returns. Addressing this requires specialized chemical auxiliaries that can effectively lock in color without compromising the fabric's original qualities.


NINGBO INNO PHARMCHEM CO.,LTD. offers SM-2020, a revolutionary wet rubbing fastness improver for reactive dyes, specifically formulated to tackle these issues. This advanced waterborne polyurethane polycation compound provides an exceptional improvement, boosting fastness by 1-2 grades, an essential enhancement for textiles prone to crocking. Its efficacy is particularly notable in demanding applications like indigo-dyed denim and other deep shades, including dark black, bright red, and turquoise blue, where color integrity is paramount.


The innovative chemistry of SM-2020 enables it to form a durable, protective film on the fiber surface through cross-linking, firmly anchoring dye molecules. This mechanism ensures superior resistance to friction under wet conditions, which is crucial for the longevity and aesthetic appeal of dark fabrics. Unlike some traditional agents, SM-2020 maintains the fabric's soft handle and does not adversely affect the shade or sunlight fastness, preserving the textile’s natural characteristics.
