Cotton and denim fabrics are staples in the textile industry, known for their versatility and comfort. However, achieving robust color fastness, especially wet rubbing fastness, in these cellulose-based materials can be a persistent challenge. NINGBO INNO PHARMCHEM CO.,LTD. introduces Wet Rubbing Fastness Improver Agent SM-2020, a specialty chemical auxiliaries supplier providing tailored solutions for cotton and denim textile finishing.


SM-2020 is specifically designed to be a highly effective wet rubbing fastness improver for cellulose fiber, making it indispensable for cotton and denim applications. This innovative agent, a weakly cationic waterborne polyurethane polycation compound, forms a protective film on the fabric surface, significantly enhancing the bond of direct, reactive, and sulfurized dyes. This results in a remarkable improvement of 1-2 grades in wet rubbing fastness, ensuring that popular denim washes and cotton garments maintain their original aesthetic and color integrity.


Our product stands out for its compatibility with cationic and non-ionic softeners, allowing for seamless integration into existing finishing baths without adverse effects on fabric handle or fastness to sunlight. This makes SM-2020 a versatile and reliable choice for cotton dyeing auxiliaries and denim finishing chemicals.


NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality Textile Auxiliaries that empower manufacturers to produce superior textiles. By incorporating SM-2020, businesses can ensure their cotton and denim products meet global standards for color fastness, leading to greater customer satisfaction and market competitiveness.
