NON THERMO-MIGRATION FINISHING
The reasons of Thermo-migration of disperse dyestuffs can easily occurred during finishing process are:
- The structure of PE fibers will be loosen under high temperature .
- Disperse dyes used for dyeing polyester has very fine particles can be easily migration.
- The emulsifier in Silicone emulsions or other finishing agents helps pulling dyestuffs out of the fibers.
