Dacron Chemical Agent│ The Application Requirement to the Dacron High Temperature Levelling Agent
High-temperature and high-pressure dyeing is the main dyeing method adopted by Dacron fiber. Owing to these characteristics of Dacron, its put forward special requirement for the leveling agent . And the difference of semi-finished Dacron fabric on the types put forward a new requirement for the high-temperature leveling agent . So besides the basic conditions, 130℃ is provided in the process of retarding and migration, some special conditions also need to be provided to semi-finished Dacron fabric. Or the special application requirement to high temperature and high-pressure dyeing will not be met. The basic function of high temperature and high-pressure leveling agent. Hydrophobic disperse dyes is applied in the Dacron fiber dyeing. But its hydrophobic property makes its difficult to dissolve in the water, which is a contradictory thing in the dyeing process in which, the water is the medium. So the dispersing agent and other surfactant is mixed in the dispersing dyeing ...
