NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce an advanced solution for textile processing: a state-of-the-art formaldehyde-free color fixing agent. Developed as a low-viscosity liquid, this textile auxiliary is specifically formulated to address the critical need for enhanced color fastness in fabrics treated with reactive dyes.

This innovative product is an environmentally conscious choice, completely free from detectable levels of free or released formaldehyde, adhering to stringent environmental standards. Its primary application is in the printing and dyeing of cotton, linen, and various blended yarns and fabrics, where it significantly improves the durability of colors against washing, rubbing, light exposure, and sweat.

The color fixing agent demonstrates excellent performance in enhancing wet fastness, achieving high grades in soaping resistant stain tests (typically grade 4 to 5), dry milling (grade 4), and wet milling (around grade 3). It also contributes positively to sunshine wet fastness, wet ironing, and sweat fastness. A key benefit is its ability to greatly reduce or prevent common issues during drying, such as moving contamination and the appearance of 'swelling' traces on wet fabric.

Composed of a polyamine active agent, this product exhibits a positive ionic nature and is easily soluble in water. It maintains stability in the presence of alkali and hard water, though sensitivity to high concentrations of electrolytes should be noted. The liquid features a pH value typically between 7 and 9 (in a 1% aqueous solution) and boasts a solid content of approximately 75%. Importantly, it is not recommended for use in water concurrently with anionic products or polymers.

Application can be achieved through standard textile finishing processes, including the Exhaust Method and the Padding Method. General guidance suggests using the product at temperatures ranging from 20 to 60°C and a pH between 5.5 to 6, with dosages or concentrations adjusted based on color depth (dark, medium, light). Pre-tests are always advised to ensure color compatibility, as a slight shade change may occur after fixing. While possessing a moderate dyeing rate, this can be influenced by adjusting pH and temperature to optimize efficiency or leveling properties.

This color fixing agent is compatible with common cationic and nonionic finishing agents like softeners and antistatic agents, offering versatility in various textile treatments. It minimally affects the fabric's handle, brightness, and chromatic light, allowing treated fabrics to maintain their desired aesthetic qualities without the need for additional auxiliaries in most processes.
