NINGBO INNO PHARMCHEM CO.,LTD. is proud to present its advanced Formaldehyde-Free Fixing Agent, a specialized chemical auxiliary designed to significantly improve the performance and durability of reactive dyeing and printing processes in the textile industry. This high-quality product is supplied as a light yellow to brown red liquid, embodying our commitment to providing effective, yet environmentally conscious, solutions.

Our Formaldehyde-Free Fixing Agent operates on a cationic principle and, as its name suggests, is completely free from formaldehyde, ensuring a safer working environment and an eco-friendlier footprint. It is engineered to tackle common challenges associated with reactive dyes, particularly enhancing the fixation of difficult shades such as vibrant reds, deep blues, strong blacks, and rich dark browns.

Utilizing this fixing agent results in several key performance benefits for finished textiles:
Enhanced Color Fastness: Provides significant improvements in wet, washing, and rubbing fastness, making fabrics more resistant to color bleed and fade during laundering and use.
Maintained Light Fastness: Helps preserve the original brilliance and intensity of colors when exposed to light.
Fabric Softness Preservation: Unlike some fixing agents, it minimizes negative impact on the fabric's natural feel, maintaining desired softness and handle.
Shade Integrity: Acts effectively without causing noticeable changes to the intended color shade.

Technically, this fixing agent has a pH value typically ranging from 4 to 5 in a 1% aqueous solution and boasts a solid content of 40%. Its excellent solubility allows it to be miscible with water, and it exhibits robust resistance to alkali and hard water, simplifying its application in various processing conditions.

The primary scope of application for our Formaldehyde-Free Fixing Agent is in the post-processing of textiles dyed or printed with reactive dyes. It is particularly effective on cotton and other cellulosic fibers, where reactive dyes are commonly used.

Application guidance is straightforward, although specific processes may require adjustment based on fabric type and desired outcome. A typical approach involves diluting the concentrated agent with 3 to 4 parts water. For the dipping process, a recommended dosage is 0.15-0.4% (o.w.f.) at a pH between 5 and 7, with a process temperature maintained between 40°C and 60°C for 20-30 minutes. Alternatively, the rolling and solidification process generally utilizes a dosage of 1.5-5g/L, with the precise amount adjusted according to the depth of the fabric color and the required washing fastness level.

Proper preparation of the textile material is crucial for achieving optimal results. Dyed materials should be thoroughly washed and soaped to remove unfixed dyes and impurities before the fixing treatment. Furthermore, it is important to avoid using this cationic fixing agent in the same bath with anionic products, as incompatible interactions could reduce its effectiveness.

Our Formaldehyde-Free Fixing Agent is commonly supplied in 160KG plastic drums, designed for safe transport and storage. Customized packaging options are also available to meet specific customer requirements. For best results and to ensure maximum shelf life, store the product in a cool, dry, and well-ventilated environment. Under these recommended storage conditions at room temperature, the product maintains its quality for up to 12 months.
