Reactive dyes are widely favored in the textile industry for their brilliant shades and strong bonding with cellulosic fibers, particularly cotton. However, achieving excellent color fastness, especially wet rubbing fastness, with reactive dyes can often be a challenge. Textile manufacturers consistently seek advanced color fastness technologies for reactive dyes to meet the rigorous quality standards demanded by the market and ensure consumer satisfaction. Insufficient wet rubbing fastness can lead to color transfer during wear or washing, diminishing the appeal and longevity of the dyed fabric.


NINGBO INNO PHARMCHEM CO.,LTD. addresses this critical need with its innovative Fixing Agent 44196. This specialized waterborne polyurethane dyeing auxiliary for cotton is engineered to significantly enhance the fastness properties of fabrics dyed with reactive, sulfur, direct, and indigo blue dyes. The core mechanism involves the waterborne polyurethane forming a protective film that reacts with the cellulosic fibers. This creates a robust barrier, preventing dye molecules from migrating or rubbing off, even under wet conditions. The result is a substantial improvement of 1 to 1.5 grades in wet rubbing color fastness, bringing the fabric's performance to over 3 grades, a benchmark for high-quality textiles.


For producers focused on improving color fastness of reactive dyed cotton, 44196 offers a powerful and reliable solution. Its effectiveness ensures that the vibrant colors achieved with reactive dyes are locked in, maintaining their intensity and preventing undesirable transfer. Moreover, in line with modern ecological mandates, our Fixing Agent 44196 is formulated without APEO or formaldehyde. This ensures compliance with strict environmental regulations, including OEKo-TEX Standard 100, making it a responsible choice for any textile manufacturer committed to sustainable production.


Beyond its technical prowess in fixing dyes, this auxiliary also brings aesthetic and tactile benefits. It helps to impart a soft hand feeling to the fabric, enhancing the overall sensory experience of the textile. Crucially, it does so without influencing the original color shade or light fastness, preserving the designer's intent and the fabric's inherent qualities. When considering a reactive dye fixing agent manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. stands out not only for its superior product performance but also for its dedication to environmental responsibility and cost-effectiveness.


Investing in advanced chemical auxiliaries like Fixing Agent 44196 means investing in the longevity and quality of your textile products. It ensures that your reactive dyed fabrics will withstand the test of time and use, satisfying discerning consumers and strengthening your brand reputation.
