In the competitive textile industry, the longevity and vibrancy of color are paramount to product quality and consumer satisfaction. A persistent challenge for manufacturers is ensuring high color fastness, particularly when using reactive and direct dyes. These dyes, while popular for their bright shades and ease of use, can be prone to bleeding during washing and fading from rubbing or exposure to perspiration. This not only compromises the aesthetic appeal of the garment but also reflects poorly on brand quality. Addressing this issue requires a specialized chemical solution that can securely lock dye molecules to the fabric fibers.

NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce a premier solution: the High Concentration Reactive & Direct Dye Fixing Agent. This advanced formulation is engineered to significantly enhance the color fastness of dyed textiles, ensuring that fabrics maintain their intended hue and intensity through repeated use and laundering. It is an indispensable auxiliary for any textile operation focused on producing high-quality, durable goods.

Product Characteristics and Performance
Our fixing agent is a dark amber colored viscose liquid, specifically designed for seamless integration into various textile processing methods. With a solid content of 60% (±2%), its high concentration ensures efficiency and cost-effectiveness. The product is cationic in nature, a key feature for its mechanism of action. When applied to fabrics dyed with anionic reactive or direct dyes, the cationic fixing agent forms strong electrostatic bonds with the dye molecules. This interaction creates a larger, insoluble complex that becomes firmly anchored within the fiber matrix, drastically reducing the dye's ability to leach out when exposed to water or friction.

One of the most critical attributes of this fixing agent is its environmental profile. It is completely free of formaldehyde and APEO (Alkylphenol ethoxylates), aligning with global environmental standards and certifications like Oeko-Tex. This makes it a responsible choice for manufacturers catering to eco-conscious markets and ensures the safety of the end-user. The pH value of a 5% solution is maintained between 5.0 and 6.0, providing a stable and controlled application environment that is gentle on fabrics.

Unparalleled Benefits for Textile Finishing
The primary benefit of using our fixing agent is the remarkable improvement in both wet and dry fastness properties. It excels in enhancing:
- Wash Fastness: Prevents color bleeding during home laundering, protecting the original garment and preventing staining of other clothes in the wash.
- Perspiration Fastness: Maintains color integrity even when exposed to human sweat, a crucial factor for sportswear and apparel worn in warm climates.
- Wet Rubbing Fastness: Reduces the crocking or transfer of color when the wet fabric is rubbed against another surface.

This product is particularly effective for fabrics dyed in dark and vibrant shades, such as deep blacks, navies, and reds, which are notoriously difficult to fix. A common concern with fixing agents is their potential to alter the final appearance and feel of the fabric. However, our formulation has been perfected to operate without adversely affecting the color tone or the hand-feel of the treated textile. The colors remain bright and true, and the fabric retains its desired softness and texture.

Application and Versatility
The High Concentration Reactive & Direct Dye Fixing Agent is highly versatile and easily soluble in water, making it suitable for various application processes, including dipping, dyeing, and padding methods. For optimal results, it is essential that the fabric is thoroughly soaped and washed to remove any unfixed or hydrolyzed dye particles before the fixation process begins. This preparation ensures that the agent works on the dye that is properly bonded to the fiber, maximizing its efficiency. The recommended dosage, such as 4 g/L for the dipping method, can be adjusted to suit specific process parameters and fabric types, providing flexibility for the dyeing master.

For any textile manufacturer aiming to elevate product quality, our fixing agent is a strategic investment. By ensuring superior color fastness, it enhances the durability and appeal of the final product, leading to greater customer loyalty.
