1. Due to oxygen in the air under the catalysis of light, and the disperse dyes of fabric have the reaction between polyester fibers and chemical agent that results in yellowing, color change; or disperse dye color becomes shallow under the action of heat sublimation. We call the decline of sublimation fastness is heat migration fastness.
2. Textile products widely use a lot of non-ionic surfactant type amino silicone micro emulsion softener that results in decline of sublimation fastness. So we can use a special heat sublimation fastness improving agent (also call polyester fixing agent) before padding to prevent decline of heat sublimation.
Special polyion compound
Appearance: yellow transparent liquid
Solubility: soluble in water
Stability: resist to acid, alkali and electrolyte
It can improve the hot sublimation fastness when use in disperse dyes. Excellent effect on the washing fastness and have little influence on fabric shining.
Padding: 30-50 g/L
Dipping； 3-5%（o.w.f） Stoving and padding after dipping.
[Packaging and storage]
