NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce our high-performance Optical Brightening Agent (OBA) NFW, a specialized chemical designed to meet the rigorous demands of the textile industry. As a leading manufacturer and supplier, we are committed to delivering products that offer exceptional quality and value. Our OBA NFW, a distyryl-biphenyl derivative, is formulated to provide unparalleled whiteness and brightness to a variety of fabrics, including cotton, polyamide, silk, and their blends.

What is Optical Brightening Agent NFW?
Optical Brighteners are chemical compounds that absorb ultraviolet light and re-emit it in the blue region of the visible spectrum. This process, known as fluorescence, masks the natural yellow cast of textiles and other materials, making them appear whiter and more vibrant. Our NFW product, which comes in an easy-to-handle yellow-greenish granule form, is particularly effective, offering a very high degree of whiteness with a slight reddish shade that is often preferred in high-quality textiles. It is an anionic compound, stable across a wide pH range of 6-12, making it versatile for various finishing processes.

Key Features and Benefits
The primary advantage of using our Optical Brightening Agent NFW is the significant improvement in the visual appeal of fabrics. In today's competitive market, the perceived quality of a product is paramount. A brighter, cleaner-looking fabric can make all the difference. Key characteristics include:
- High Affinity: It demonstrates excellent and appropriate affinity for cotton and polyamide fibers, ensuring effective and even application.
- Stability: OBA NFW is stable in the presence of reducing agents or peroxide, which is crucial for modern textile processing that often involves bleaching and other chemical treatments.
- Versatile Application: It is suitable for exhaust application methods for both cotton and cotton/polyamide blend fabrics, integrating smoothly into existing production lines.

Application Guidelines
For optimal results, we recommend specific concentrations and conditions. For example, in an exhaust application for cotton, a dosage of 0.05-0.15% at 90-100°C for 30-40 minutes is typically effective. For polyamide and cotton blends, a slightly higher concentration may be required. Adhering to these parameters ensures you achieve the maximum whitening effect without compromising fabric integrity. As a trusted supplier, we provide detailed technical support to help you determine the best process for your specific needs. When considering where to buy or the price of optical brighteners, it is essential to factor in the quality and consistency offered by a reliable manufacturer.
