Heat-resistant yellowing prevention agent

Appearance light yellow transparent liquid with a pH value of about 3 (100% sol.)

Ionic anionic solubility easily soluble in cold water

Special surface activity composition

The heat-resistant anti yellowing agent QT-HIBITER3 has a good effect on preventing yellowing of nylon and polyester during high-temperature setting. To prevent discoloration (yellowing) during pre molding or post processing of embryonic fabrics, it can provide a better whiteness effect.

Features and Uses

1. For the yellowing phenomenon caused by preheating, setting, and high-temperature processing of nylon or polyester fabrics, it is recommended to use heat-resistant anti yellowing agent QT-HIBITER3 for initial treatment, so that the finished fabric will have good whiteness

2. Heat resistant anti yellowing agent QT-HIBITER3 with low foaming ability

[Usage]

The usage and treatment of heat-resistant anti yellowing agent QT-HIBITER3 are as follows:

Performance evaluation

1. Phenol yellow resistance test Adidas method (a. whiteness can reach 3.5-4 levels after scouring and washing; b. whiteness can reach 5 levels after anti yellowing processing)

2. Foaming:

Additive 3 g/L, bath volume 1.5 L, acetic acid 1 g/L

→ Simulate the on-site impact condition, and the bubble height is as follows: unit (cm)
