Optical brightener EBF-L is a high performance optical brightener specially designed for use in the textile dyeing industry. This product is used to improve the brightness of polyester and polyester blended fabrics, especially under low temperature and strong light conditions. It has good properties and can improve the light resistance and brightness of the fabric.

Product application:
1. Whitening of polyester fabric:
- Pure Polyester: Improves the whiteness and brightness of polyester fabrics, ensuring bright and long-lasting results even in harsh environmental conditions.
- Polyester blended fabrics: Suitable for improving the brightness of polyester-cotton blends and other blended fabrics.

2. Low temperature dyeing process:
- Effective at lower temperatures: Suitable for processes with temperatures around 95°C, suitable for low-temperature dyeing operations.

3. High sunshine:
- Lightfastness: Maintains good brightness even when exposed to sunlight for long periods of time, ensuring the fabric remains bright and bright.

Product advantages:
1. High whitening efficiency:
- Effective even at low concentrations: Improves the whiteness and brightness of polyester fabrics, ensuring bright and long-lasting results even in harsh environmental conditions.
- Enhanced brightness: Provides high whiteness, significantly improving the visual appeal of fabrics.

2. Good light resistance:
- Light fastness: The light fastness reaches level 6-7, ensuring that the whitening effect can last even if exposed to the sun for a long time.
- Stable performance: Maintains stable effects for a long time and provides reliable performance under various environmental conditions.

3. Chemical stability:
- Acid and alkali resistant: Resistant to acidic and alkaline conditions, maintaining its whitening properties throughout the dyeing process.

- Suitable for a variety of methods: This versatility ensures that the optical brightener EBF-Lt meets every need, increasing the efficiency and effectiveness of textile processing.

Instructions for use:
1. Add method:
- Recommended dosage: 0.5-4 grams per liter of solution.
- Process: Using a two-bath process, the dipping rate is 70%. It is then pre-dried and cured at 170-190°C for 30-40 seconds.

2. Soaking method:
- Recommended dosage: Use 0.2-0.5% (O.W.F) of optical brightener EBF-Lt.
- Conditions of use: The bath ratio is 1:10-20, and the pH value is 5-10 (try to use a weakly acidic bath). Process at 95-100°C for 30-60 minutes, then wash, dry and style thoroughly.

By following these instructions for use, users can achieve ideal whitening and brightening effects on polyester and polyester blend fabrics, improving the overall quality and appearance of the fabric.
