Cellulose fibers, including cotton, linen, and viscose, form the backbone of a vast segment of the textile industry due to their natural feel, breathability, and versatility. However, achieving optimal color fastness, especially wet rubbing fastness, remains a persistent challenge in cellulose fiber dyeing and processing. Dyes, particularly direct, reactive, and sulfurized types, can be prone to rubbing off when wet, leading to color transfer and diminishing fabric quality.


To overcome these challenges, NINGBO INNO PHARMCHEM CO.,LTD. proudly presents Wet Rubbing Fastness Improver Agent SM-2020. This specialized Textile Auxiliary is specifically formulated to enhance wet rubbing fastness for cellulose fibers. As a waterborne polyurethane polycation compound, SM-2020 acts by effectively cross-linking with the active groups present on the fiber surface and forming a protective film. This innovative mechanism significantly improves the dye's anchorage within the fiber structure, preventing color migration even under intense friction.


For textile manufacturers, the integration of SM-2020 means a tangible improvement in product performance. It boosts wet rubbing fastness by 1-2 grades, allowing even the most challenging deep colors, such as dark blacks and vibrant reds, to achieve more than 3 grades of fastness. Crucially, this enhancement is achieved without negatively impacting the fabric's soft handfeel or its original shade, which is vital for maintaining product appeal. SM-2020 is thus an indispensable textile dyeing auxiliary for improved durability.


NINGBO INNO PHARMCHEM CO.,LTD., a reputable supplier of textile wet fastness chemicals, ensures that SM-2020 is also an eco-friendly solution, free from harmful substances like APEO and formaldehyde. This makes it a responsible choice for modern cellulose fiber dyeing and processing operations. When you choose to buy SM-2020 wet rubbing agent, you are investing in a product that not only delivers superior color durability but also supports sustainable textile production. Ensure your cellulose fiber products stand out with lasting color vibrancy and quality.
