 Dye excellent
in fastness among other basic dyes is called YR CATIONIC
DYES and YR BASIC DYES.
YR CATONIC
DYES produce the most clear color and excellent in color field.
As Cationic
dyes has a positive(+) charge, they are fixed with fibers by
the ion bond which has acid radical
like acryl fibers.
Using Cationic
dyes together with those with negative (direct dye, acid dye,
Reactive dye, Disperse dye,
etc) causes precipitation, it is necessary to
use anti-precipitation chemicals.
Dye stains
can be prevented by using the dye lenitive, whereas dye stains
can develop when the speed of
dye coloring differs in case of combined dye of
different colors.
Therefore the use of dyes which have about the
same speed of coloring, or have good compatibility is advised.
The classification of YR cationic dyes in terms
of their use can be categorized into nine levels from AA,
which has a good fastness of coloring to EE, which
is slow in coloring by indicating Mixture Index
(abbr., I-Mix). In Europe, K-Value(Fast 1 to Slow5)
is categorized into five levels.
Metallic
ion dissolving in water and active chlorine can influence on
dyeing and coloring. Among metallic ions,
Cu++, Fe++ inflence on the shade of color, and
Ca++, Mg++ on fatness of dyeing.
Therefore using soft water is recommended if possible.
Besides, it needs noting that if the pH of the
using water is high, some dyestuffs discolor.
YR Cationic
and basic dyes are used for C.D. Polyester, paper, ink, and
wood acryl fibers, but mainly for
acryl fibers.
Dissolution
of dyestuff
It should be completely dissolved by applying
boiling water over 80¡É after a good stirring of the dyestuff
in the nitric acid of half quantity of the stuff.
Since there is a huge gap in fusibility between
high and low temperature, the dissolution of dyestuff should
be made in high water(70-90¡É) .
Bath stability
Some of the Cationic dyestuffs dissolve in dyeing
bath of pH 3.5-4.5 or in the high temperature without dyed
stuff. However, in actual dyeing, the dyestuffs
are absorbed as the temperature rise and fibers are there,
making the absorbed dyestuffs safe.
Therefore, in actual dyeing, required color can
be obtained even though the stuff dissolves in the bath
stability testing in which the fabrics are not
contained.
Influence
of pH
As Cationic dyestuffs have the property of dissolving
in an alkaline bath and in a strong acid one and
changes to colorless, the pH of dyeing bath needs
to be adjusted to 2.5-4.5.
One of the reasons of reproduction of a bad color
lies in failing to maintain the pH according to its change
by controling the quantity of acid.
1. About 0.8% of dyeing is needed for YAITEX WHITE AWS like other Cationic dyestuffs by fixing PH 4~5 with the
density of 0.W.F.
2. YAITEX WHITE ATR Conc
zinc hydrochloric acid - 5%
oxalic acid - 1.5%
Sodium Nitride - 1.5%
ATR Conc(dyestuff) - 0.1.~0.2%
with these proportions, it becomes PH 3~3.5. Raise the temperature slowly by putting the fiber into this salt bathing and take out after boiling for 5 to 10 minutes at 100¡É
