Textile Carrier.
A carrier is an organic chemical that has affinity to
polyester and swells it. Chemicals such as Biphenyl, Orthophenylphenol, Benzyl
benzoate, Benzyl benzoate and Butyl Phathalamide have been used as disperse
dyes carriers. The use of Carrier at
100°C increases the amount of dye absorbed and decrease staining on other
fibers. Carrier normally have unpleasant odour
that require the dyebath to be enclosed and they may also be toxic.
Above swatches are Disperse dyed at 100°C, Exhaust
1. Dyed without carrier
2. Dyed with Carrier of Company X.
3. Dyed with carrier of Company Y.
What Carriers do?
Carrier helps in further penetration and resultantly better
washing, rubbing and sublimation than with same dyeing depth without carrier at
elevated temperature. Dyeing at high temperature without carrier is more
economical than dyeing with carriers.
Experiment
Let’s do a test to confirm that Carriers can enhance
fastness. We will dye two fabrics with same dye same concentration at elevated
temperature of 130°C but, one with and other without carrier than we will do
RC(Reduction Cleaning) and finally will apply test Sublimation test ISO 105 PO1
210°C.
Right one Without
Carrier and left with carrier.
One can observe
obvious improvement in sublimation fastness due to addition of career.
