Heptol GL
Heptol
BL Heptol
AL |
|
Sequestering and dispersing agent for
cotton dyeing with reactive and direct dyes, Heptol
GL, at the beginning of dyeing, is able to
inhibit calcium and magnesium ions,
eliminating their influence on dye affinity thus preventing rapid and
uneven dye striking commonly caused by water hardness. When soda ash is added to the dyebath
in the stage of dye fixation, Heptol GL acts as an excellent dispersing agent for calcium
carbonate, securing bright dyeings with soft handle achievable even in hard
water. In the subsequent soaping off, Heptol GL counteracts the influences on dye substandtivity
imposed by water hardness, facilitating the removal of unfixed dyes and
preventing their redepositions back to the fibre, and thus achieving optimum
wet fastness properties thereafter. |

Heptol GLF
Heptol
BLF Heptol
ALF |
|
Sequestering and dispersing agent for
cotton dyeing with reactive and direct dyes, Heptol
GLF functions in the dyebath first as a
leveling agent against rapid striking caused by water hardness, and later
when soda ash having been introduced into the dyebath, as a dispersing agent
for calcium carbonate. Heptol GLF acts as a
foam free soaping agent in the subsequent washing off of unfixed dyes. Heptol GLF is
recommendable when good dispersing properties particularly against iron ions
are needed. |

Heptol CMG
|
|
Sequestering and dispersing agent for dyeing
and pretreatment, Heptol CMG has an
excellent binding and dispersing capacities towards alkaline earth metal and
heavy metal ions, acting in a dyebath leveling and dispersing agent against
water hardness particular containing excess iron ions, acting as a dispersing
agent against calcium silicate deposition in cold-pad-batch dyeing and acting
as a soaping agent in the soaping off of reactive dye dyeing for optimum wet
fastness performances. Heptol CMG is also suitable for dyeing with dyes of all kinds
except cationic dye. |
||
Heptol WZB
|
|
Sequestering and
dispersing agent for dyeing and pretreatment, Heptol
WZB has outstanding binding capacities towards
alkaline earth metal and heavy metal ions, excellent dispersing capacities
against insoluble carbonates and silicates. It is widely used in alkaline scouring
and peroxide bleaching of cotton pretreatment, in dyeing and soaping off of
reactive dyeings, and is highly recommendable for processes using sodium
silicate. |
||
Heptol CTA
|
|
Powdered water softening and dispersing
agent for dyeing reactive dye and direct dyes, Heptol
CTA is also for general washing off of textile
substrates. Heptol CTA
has a remarkable dispersing capacity against insoluble carbonate, in dyebaths
containing soda ash it can prevent deposition of calcium carbonate even in
hard water of high degree. Heptol CTA has an
outstanding complexing capacity towards calcium and magnesium ions, in the
soaping off of reactive dyes, it can help to produce dyeings very fast to
washing. |
