TY-8903 Antioxidant Agent

TY-8903 is a high-temperature antioxidant agent specifically designed to combat the yellowing of polyamide (nylon) and its blends during heat treatment processes. It is the ideal solution for protecting pure white fabrics and stabilizing light-colored fabrics.

This agent is particularly effective for fabrics containing elastic fibers, ensuring they maintain their intended color and brightness through high-temperature finishing.

Key Characteristics & Performance Advantages

1. Prevents Heat-Induced Yellowing:

   • Effectively reduces the yellowing of pure white and stabilizes light-colored polyamide fabrics during heat treatment (e.g., pre-setting or post-setting).

   • Prevents yellowing during contact heat treatment as well, such as during pressing or molding tests.

2. Enhances Color Accuracy and Brightness:

   • Ensures accurate and reproducible processing with a stable whitening effect and reduced color variation between batches.

   • It actively improves the whiteness of pure white fabrics and enhances the brightness of light-colored fabrics.

3. High Efficiency and Ease of Use:

   • The formula is highly efficient, requiring only a low dosage to achieve excellent results.

   • It is easy to use in continuous processes and causes no color change, ensuring excellent reproducibility.

4. Good Compatibility:

   • TY-8903 is compatible with most softeners and other finishing auxiliaries, allowing for flexible and integrated finishing routines (pre-testing is always recommended).

Recommended Application Process

Processing Method: Continuous Process (Padding)

1. Pre-setting:

• Dosage: 2–5 g/L of TY-8903 Antioxidant Agent

• pH: 5.0–6.0 (adjust with acetic acid or citric acid)

2. Post-setting:

• Dosage: 2–8 g/L of TY-8903 Antioxidant Agent

• pH: 5.0–6.0 (adjust with acetic acid or, preferably, citric acid)

Note: The antioxidant agent can also be used in the same bath with other finishing auxiliaries, but compatibility testing should be conducted in advance.

Storage and Packaging

• Storage: Store in a cool, ventilated, and sealed warehouse.

• Recommended Storage Temperature: 5–30°C.

• Packaging: Available in various sizes. Please inquire for details.
