Embodiment １

[0015] An anti-yellowing finishing agent for light-colored fabrics and a preparation process thereof: comprising the following steps:

[0016] (1) 20 parts of 4-hydroxyphenethylamine, 20 parts of isopropanolamine, 10 parts of 4-chloro-2-nitroanisole, 6 parts of benzotriazole, 2-nitro-3-amino Add 16 parts of phenylhydrazine and 12 parts of o-acetylsalicylic acid into the stirrer and stir, then add 8 parts of dehydrocresinolide, raise the temperature to 40°C, and stir for 22 minutes;

[0017] (2) Add 12 parts of isopropanolamine and 100 parts of distilled water to step (1), keep the temperature at 65°C, and let it stand for 7 minutes;

[0018] (3) Subsequently, 6 parts of 2-nitro-3-chlorophenylhydrazine and 12 parts of glacial acetic acid are successively added dropwise to step (2). After the addition is completed, stir at a temperature of 60°C for 50 minutes to obtain the Antioxidant finishing agent for textiles.

Embodiment ２

[0020] An anti-yellowing finishing agent for light-colored fabrics and a preparation process thereof: comprising the following steps:

[0021] (1) 22 parts of 4-hydroxyphenethylamine, 15 parts of isopropanolamine, 12 parts of 4-chloro-2-nitroanisole, 8 parts of benzotriazole, 2-nitro-3-amino Add 15 parts of phenylhydrazine and 18 parts of o-acetylsalicylic acid into the stirrer and stir, then add 8 parts of dehydrocresinolide, raise the temperature to 45°C, and stir for 25 minutes;

[0022] (2) Add isopropanolamine 10 and distilled water 110 to step (1) to keep the temperature at 65, and let it stand for 7 minutes;

[0023] (3) Then add 5-10 parts of 2-nitro-3-chlorophenylhydrazine and 12 parts of glacial acetic acid dropwise to step (2) successively. After the dropwise addition, stir at a temperature of 65°C for 30 minutes to obtain the textile Antioxidant finishing agent.

Embodiment ３

[0025] An anti-yellowing finishing agent for light-colored fabrics and a preparation process thereof: comprising the following steps:

[0026] (1) 20 parts of 4-hydroxyphenethylamine, 22 parts of isopropanolamine, 10 parts of 4-chloro-2-nitroanisole, 8 parts of benzotriazole, 2-nitro-3-amino Add 15 parts of phenylhydrazine and 18 parts of o-acetylsalicylic acid into the stirrer and stir, then add 8 parts of dehydrocresinolide, raise the temperature to 45°C, and stir for 22 minutes;

[0027] (2) Add 15 parts of isopropanolamine and 110 parts of distilled water to step (1), keep the temperature at 65°C, and let it stand for 7 minutes;

[0028] (3) Then add 5-10 parts of 2-nitro-3-chlorophenylhydrazine and 12 parts of glacial acetic acid dropwise to step (2) successively. After the dropwise addition, stir for 40 minutes at a temperature of 70°C to obtain The textile antioxidant finishing agent.
