In the dynamic world of textile manufacturing, achieving vibrant, durable colors that withstand washing, light exposure, and wear is paramount. Textile finishing plays a critical role in locking in dyes and enhancing fabric performance. However, traditional finishing agents, particularly those containing formaldehyde, pose environmental and health concerns, driving the demand for safer, more sustainable alternatives.

NINGBO INNO PHARMCHEM CO.,LTD., a company committed to providing innovative chemical solutions, offers RG-E906, a state-of-the-art formaldehyde-free fixing agent designed specifically for textile finishing. This product represents a significant advancement in auxiliary chemicals, allowing manufacturers to meet stringent ecological standards without compromising on quality or performance.

RG-E906 is presented as a light yellow, transparent liquid with low viscosity, making it easy to handle and incorporate into various finishing processes. Its key physical and chemical indicators highlight its suitability: it is a cationic product with a pH value of 7-9 in a 1% aqueous solution. A solid content of 40% ± 1 ensures concentrated performance. RG-E906 exhibits good solubility in water, alkali, and even hard water, facilitating its dispersion and application. However, its cationic nature means it should not be used in the same bath with anionic surfactants or polymers, requiring careful process management to avoid incompatibility.

One of the most significant advantages of RG-E906 is its completely formaldehyde-free composition. Tested according to national standards GB/T2912.1-1998 and GB/T2912.2-1998, it shows zero free formaldehyde and zero formaldehyde content. This feature is crucial for textile manufacturers seeking to produce Oeko-Tex certified fabrics and comply with increasingly strict global environmental regulations regarding harmful substances in textiles. By choosing RG-E906, manufacturers can enhance product safety for consumers and improve working conditions for their employees.

The performance characteristics of RG-E906 are impressive. It is highly effective as a fixing agent for a wide range of fabrics, including cotton, linen, and their blends. Beyond cellulosics, it also serves effectively as a dyeing agent for blends containing nylon, wool, and cotton. It is particularly noted for its ability to significantly improve post-wet fastness, a critical measure of how well a dyed fabric resists bleeding when wet. It also enhances light fastness, wet ironing rate, and perspiration fastness. After treatment with RG-E906, fabrics dyed with reactive, direct, acid, and sulphur dyes demonstrate high fastness ratings, with soaping anti-staining reaching 4-5, dry rubbing fastness 4, and wet rubbing fastness around 3.

Another key benefit is the product's ability to reduce or prevent migration and "swelling" marks that can form during the drying or partial drying of wet fabrics. This ensures a more uniform and consistent color appearance across the entire fabric area, maintaining the original vividness and shade without being affected by the fixing process itself. Unlike some traditional fixing agents, RG-E906 typically does not require additional additives during application, simplifying the process and potentially reducing chemical inventory.

RG-E906 offers versatility in application, being suitable for both impregnation and padding methods, allowing manufacturers to integrate it into their existing finishing lines. For the impregnation method, recommended dosages vary based on color depth: 4-6% owf (on weight of fabric) for dark colors, 2-4% owf for medium colors, and 0.5-1% owf for light colors. The typical process involves a bath ratio of 1:6-15, a temperature of 60-70°C, and an immersion time of 10-30 minutes. For the padding method, dosages are 15-30g/L for medium to dark cloth and 8-15g/L for light cloth, applied at normal temperature before drying and tentering.

It is essential to dilute RG-E906 with water before adding it to the finishing solution. As mentioned, its incompatibility with many anionic products requires careful consideration. It is recommended to clean the dyeing solution and any residual anionic substances thoroughly before applying RG-E906 in a separate bath to ensure optimal performance and avoid unwanted reactions or precipitation.

The product has minimal to no effect on the hand feel of the fabric, preserving the textile's inherent softness and drape, which is important for consumer comfort and appeal. While stable in acidic conditions, alkaline conditions should be avoided for optimal results. It is generally stable to typical hard water, but sensitivity to high electrolyte concentrations requires careful formulation in baths containing significant salt levels.

For packaging and storage, RG-E906 is typically supplied in 150KG plastic drums, or packaging can be customized according to customer requirements. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances. Under proper storage conditions at room temperature, the product has a shelf life of 12 months.
