Cellulose fibers, encompassing cotton, linen, and rayon, are cornerstones of the textile industry, valued for their comfort and versatility. However, dyeing these natural fibers, especially to achieve deep and vibrant shades, often presents challenges, particularly concerning color fastness. NINGBO INNO PHARMCHEM CO.,LTD. addresses these specific needs with SM-2020, a premium among specialty auxiliaries for cellulose fiber dyeing.


SM-2020 is a waterborne polyurethane polycation compound specifically formulated to deliver exceptional cellulose fiber wet rubbing improvement. Its unique chemistry allows it to effectively cross-link with the active groups present on cellulose fibers, forming a protective film. This innovative mechanism is crucial for enhancing the durability of colors applied with direct, reactive, and sulfurized dyes, preventing color transfer and boosting overall fastness.


For manufacturers seeking a reliable cotton dyeing auxiliaries manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. offers SM-2020 as a go-to solution. It has proven particularly effective in improving the wet rubbing fastness of challenging deep colors like dark black, bright red, and turquoise blue, often elevating fastness by 1-2 grades, reaching levels above 3 grades. This translates into higher quality finished goods and greater customer satisfaction.


Beyond its impressive performance on fastness, SM-2020 is designed with fabric integrity in mind. It ensures that the dyed fabric's strength and original soft handle are preserved, while also having no adverse effect on sunlight fastness or shade. This comprehensive approach makes it an invaluable addition to any dyeing process involving reactive dyes on cellulose fiber or other common dye types.
