Uses
Used in Textile Industry:Disperse red 129 is used as a dye for polyester and blended fabrics due to its excellent ironing fastness, light fastness, perspiration fastness, and washing fastness. It provides a vibrant and long-lasting color to the fabrics, making it a popular choice for various textile applications.
Standard:
The fastness properties of Disperse red 129 are measured according to the AATCC (American Association of Textile Chemists and Colorists) standards, which ensure the quality and performance of the dye in different conditions.
Ironing Fastness:
Disperse red 129 exhibits a rating of 4 on the AATCC scale, indicating good resistance to ironing, which is essential for maintaining the color and appearance of the fabric after ironing.
Light Fastness:
With a rating of 5-6, Disperse red 129 demonstrates excellent resistance to fading when exposed to light, ensuring the fabric's color remains vibrant and consistent over time.
Perspiration Fastness:
The dye has a perspiration fastness rating of 5, which means it maintains its color well even when the fabric comes into contact with sweat, making it suitable for clothing that requires frequent washing and exposure to moisture.
Washing Fastness:
Disperse red 129 also has a washing fastness rating of 5, indicating that the color remains stable and does not fade or bleed during the washing process, ensuring the fabric's longevity and appearance.
Fading:
The fading resistance of Disperse red 129 is rated 5, which means it is highly resistant to fading, making it an ideal choice for fabrics that are frequently exposed to sunlight or other sources of light.
Stain:
The stain resistance of Disperse red 129 is also rated 5, indicating that the dye is less likely to transfer or stain other fabrics when in contact, ensuring the fabric's color remains consistent and does not affect other garments during washing or wear.

The CAS Registry Mumber 12236-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 12236-23:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*2)+(1*3)=66
66 % 10 = 6
So 12236-23-6 is a valid CAS Registry Number.
