Haptic Coatings
Screen printing technology can be
automated quite easily compared to
stitching operations. By applying haptic coatings for upper design, there is no
need for joining other materials on top
of the base mesh by a sewing operation.
This results in very efficient and less labor
intensive production of footwear uppers.
Sustainability Considerations
Today, sustainability is a must for all new
developments in the sporting goods industry. Right from the beginning, haptic
coatings were developed with a clear goal
of offering the best sustainability along
with hard fact manufacturing and cost
advantages. Two main features lead to
high sustainability: haptic is an additive
manufacturing technology, and haptic is
fully water-based.
The additive manufacturing approach
allows building up coating thickness step‐
by‐step. During that process, the coating
material is selectively added at the loca-
tion where it is needed. There is no cutting
waste for disposal and coating material
loss is very low. Material loss basically
only appears when colors are changed
and screens are cleaned. Therefore, high-
est material efficiencies can be achieved.
The fully waterborne chemistry guarantees safe and healthy work places and
is in full compliance with the goals of
ZDHC, an industrywide campaign to
face out toxic chemicals within the textile
supply chains. 3 Workers enjoy clean and
fresh air without inhaling solvents. This
is especially important when operating in
less developed countries where extraction
systems are often not up to requirements.
Importantly, there is no fire hazard in the
factory and workers do their job in a safe
environment.
Conclusions
Haptic coatings offer a great new op-
portunity for athletic footwear manu-
facturing. High efficiency at low cost,
sustainable chemistry and application
processes leads to multiple benefits within
the supply chain. In addition the selective
additive 3D coating approach allows cre-
ative spectacular designs not seen before
in the footwear industry. CW
