Reactive and sulfur dyes are widely used in the textile industry for their vibrant colors and good wash fastness, particularly on cellulose fibers. However, a common challenge associated with these dyes is achieving satisfactory wet rubbing fastness, especially for deep shades. This can lead to color transfer and diminish the overall quality and lifespan of the finished textile product.


To overcome this, manufacturers require specialized finishing agents that can effectively enhance color durability. NINGBO INNO PHARMCHEM CO.,LTD. introduces SM-2020, a cutting-edge wet rubbing fastness improver for reactive dyes and sulfur dyes. This advanced waterborne polyurethane polycation compound is engineered to deliver exceptional results, significantly improving wet rubbing fastness by 1-2 grades. It ensures that even challenging colors like dark black, bright red, and turquoise blue maintain their integrity under friction.


The mechanism of SM-2020 involves forming a durable, protective film on the fiber surface through cross-linking, which securely anchors dye molecules. This not only prevents color migration but also ensures that the dyed fabric's original fastness properties, soft handle, and shade remain unimpaired. Its weakly cationic nature and excellent compatibility with non-ionic products make it versatile and easy to integrate into existing dyeing processes.


Beyond its high performance, SM-2020 stands out for its environmental safety. As an eco-friendly wet rubbing fastness improver cellulose fiber, it is free from APEO, formaldehyde, organic halides, and heavy metals, complying with strict EU standards. This makes it an ideal choice for textile companies committed to responsible and sustainable manufacturing practices.
