Polyurethane (PU) chemistry has emerged as a cornerstone in modern textile dyeing and finishing, offering versatile solutions that enhance fabric performance and durability. Known for their excellent film-forming properties and adhesive strength, polyurethane-based solutions are revolutionizing how textiles achieve superior color fastness, soft handle, and overall longevity. The unique molecular structure of polyurethanes allows for intricate interactions with various fiber types, making them invaluable in advanced textile processing.


NINGBO INNO PHARMCHEM CO.,LTD. harnesses the power of this versatile polymer to develop high-performance textile auxiliaries. A prime example is our Wet Rubbing Fastness Improver Agent SM-2020, a waterborne polyurethane polycation compound. This innovative product is specifically designed to significantly improve the wet rubbing fastness of direct, reactive, and sulfur dyes on cellulose fibers. The 'waterborne' aspect underscores its eco-friendly nature, aligning with contemporary demands for sustainable manufacturing practices and reducing the environmental impact of chemical processes.


The effectiveness of SM-2020 stems from its ability to cross-link with active groups on the cellulose fiber, forming a protective yet flexible film on the fiber surface. This mechanism effectively locks in the dye, preventing color migration and transfer even under intense wet friction. For manufacturers, this translates to fabrics with enhanced color durability and higher quality, meeting stringent international standards and consumer expectations. Importantly, these polyurethane textile chemicals do not compromise the fabric’s original feel or shade, ensuring aesthetic appeal alongside functional improvement.
