Along with many diverse
finishing treatments, VATEKS uses three types of web bonding technologies in its
nonwoven production. These are:
Bonding (Cross-laid, Parallel, Random): refers to the application of a liquid based
bonding agent to the web. Three groups of materials are commonly used as
binders-acrylate polymers and copolymers, styrene-butadiene copolymers and
vinyl-acetate ethylene copolymers. The binder can be applied uniformly by
impregnating, coating or spraying or intermittently, as in print bonding.
Thermobonding: refers to the use of
thermoplastic properties of certain synthetic fibers to form bonds under
controlled heating. Usually a low melt fiber or bicomponent fiber is introduced
at the web formation stage to perform the binding function later in the process.
Among several thermal-bonding systems, Vateks is using the calendaring system,
where heat and high pressure applied through rollers to weld the fiber webs
together at speed.
(Mechanical Bonding): refers to the strengthening of the web by
inter-fiber friction as a result of the physical entanglement of the fibers.
Among the two types of mechanical bonding, Vateks is using needle punching
system, where specially designed needles are pushed and pulled through the web
to entangle the fibers.
In order to meet the further
demands of our valued customers, a range of Technologies which can add diverse
properties are at their services. These are:
