Abstract
As we know polyester is a synthetic fiber and has
more crystalline structure than natural fibers. In continuous
dyeing of polyester by pad-Thermosol process, there are many
advantages such as bulk production, low-cost, good efficiency etc.
But during dyeing process there is a severe problem occurs that
is dye migration .in order to control the dye migration different
migration inhibitors are used in this project. Both natural and
synthetic migration inhibitors are applied on the 100% polyester
fabric in order to compare that which migration inhibitor hives
better results on the pad-Thermosol process.
After comparing the different properties of the both migration
inhibitors the synthetic inhibitors found more efficient then the
natural one. The following tests were conducted during project:
Migration test, tensile strength, color strength, bending length,
light fatness.
Synthetic migration inhibitors gives better results for the tests
which were conducted .but there is a problem that the synthetic
migration inhibitors are not environmental friendly and they are
costly then natural migration inhibitors.
