NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of a state-of-the-art, high-performance formaldehyde-free color fixing agent. This innovative product is specifically designed to address the critical need for enhanced color fastness in cotton, linen, and blended textiles, while also meeting stringent environmental standards.

In the dynamic world of textile production, achieving durable and vibrant colors that withstand washing, rubbing, and environmental exposure is paramount. Traditional fixing agents have often posed concerns regarding formaldehyde content, impacting both environmental safety and human health. Recognizing this, NINGBO INNO PHARMCHEM CO.,LTD. has focused on developing solutions that deliver exceptional technical performance without compromising safety or sustainability.

Our formaldehyde-free color fixing agent is a positive ionic, low-viscosity liquid auxiliary. Its unique polyamine active agent composition ensures excellent solubility in water and resistance to alkali and hard water conditions, facilitating ease of use in various textile processing environments. The product boasts a solid content of approximately 75%, indicative of its concentrated efficacy.

A key feature of this fixing agent is its formaldehyde-free status. Rigorous testing confirms zero content of free and released formaldehyde, aligning with global environmental regulations and providing a safer alternative for textile manufacturers and end-users. This makes it an ideal choice for brands focused on eco-friendly and sustainable production practices.

Application of this fixing agent significantly improves the wet fastness properties of fabrics dyed with reactive, direct, acid, and sulfur dyes. Fabric treated with this product can achieve soaping resistant stain grades of 4 to 5, dry milling grade 4, and wet milling grade 3 or higher. These improvements are crucial for preventing color bleeding and migration during washing and wear, ensuring the longevity and appearance retention of textile products.

Furthermore, the agent helps to improve sunshine wet fastness, wet ironing fastness, and sweat fastness. It is also effective as a resist agent for nylon, wool, and cotton blended fabrics, enhancing the washing fastness and other properties of nylon fibers dyed with acid dyes. A notable benefit is its ability to greatly reduce or prevent wet fabric from contamination and "swelling" traces during drying processes, contributing to more uniform and aesthetically pleasing results.

The fixing agent is designed to have minimal to no adverse effect on the fabric hand feel, brightness, or chromatic light, preserving the original aesthetic qualities of the textile. Its application process is designed for simplicity and convenience, often eliminating the need for additional auxiliaries when solely focusing on color fixing. While stable under acidic conditions and to general hard water, sensitivity to high concentrations of electrolytes should be noted, and alkaline conditions should be avoided for optimal performance.

Application can be performed via the Exhaust method or the Padding method. For the Exhaust method, typical application quantities range from 0.1% to 1.2% depending on color depth (light, medium, dark) and fabric type, applied in a solution at 45-60 ºC and a pH of 5.5-6 for 20-25 minutes. The Padding method involves immersing textiles in a solution with 1.0 to 12 g/l concentration at 20-30 ºC and a pH of 5.5-6, followed by drying at 100-120 ºC. Precise dilution with water before application is essential for successful integration.

Important considerations during application include potential slight changes in fabric color after fixing, necessitating testing before color matching. The product exhibits a moderate dyeing rate, which can be influenced by pH and temperature; lower pH and higher temperatures promote dyeing rate, while higher pH and lower temperatures reduce it, potentially improving levelling properties. The agent is compatible with cationic and nonionic softeners or antistatic agents in water. It is worth noting that the product is very difficult to completely remove during stripping processes.

Packaging is typically available in 160KG plastic drums, though customized requests can be accommodated. The product should be stored in a cool, dry place and has a shelf life of 12 months under room temperature. It is transported as non-dangerous goods, ensuring safe handling and logistics.

For textile manufacturers seeking to enhance the durability and fastness of their dyed and printed fabrics while adhering to environmental responsibility, this formaldehyde-free color fixing agent from NINGBO INNO PHARMCHEM CO.,LTD. represents a superior solution.
