Polyurethane (PU) chemistry has revolutionized various industries, and its application in textiles is no exception. In the realm of dyeing and finishing, PU-based compounds are emerging as critical components for improving fabric performance, particularly in areas like color fastness. These innovations address long-standing challenges in textile production, offering solutions that are both effective and environmentally sound.


NINGBO INNO PHARMCHEM CO.,LTD. exemplifies this advancement with SM-2020, a prime example of a sophisticated waterborne polyurethane polycation compound textile auxiliary. This product is specifically designed to act as an exceptional wet rubbing fastness improver. Unlike traditional fixing agents, the unique molecular structure of SM-2020 allows it to form a durable, cross-linked film on the fiber surface. This mechanism effectively anchors dye molecules, significantly enhancing the fabric's resistance to friction under wet conditions.


The impact of SM-2020 is profound: it improves wet rubbing fastness by 1-2 grades, a critical upgrade for direct, reactive, and sulfurized dyes on cellulose fibers. This is especially vital for dark shades such as dark black, bright red, and turquoise blue, which are notoriously difficult to stabilize. Furthermore, SM-2020 achieves these results without compromising the fabric's soft handle, original shade, or sunlight fastness, ensuring superior product quality.


Beyond its performance benefits, the innovation of SM-2020 extends to its environmental profile. It is an eco-friendly wet rubbing fastness improver cellulose fiber, formulated free of APEO, formaldehyde, organic halides, and heavy metals. This commitment to clean chemistry aligns with global sustainability initiatives and meets stringent EU standards, providing manufacturers with a responsible solution for their dyeing processes.


As a dedicated supplier of APEO-free wet rubbing fastness agent, NINGBO INNO PHARMCHEM CO.,LTD. is instrumental in bringing these cutting-edge PU-based solutions to the market. For those looking to buy wet rubbing fastness improver for reactive dyes, understanding the technological advantages and the competitive SM-2020 wet rubbing fastness agent price is essential. SM-2020 represents the future of textile chemistry, offering an innovative pathway to enhanced durability and sustainable production.
