Elasticity in spunbond fiber
is a great advantage. Elasticity so far was
mainly governed by composite structure of material
and other mechanical means. Exxon has introduced
its elastomeric Metallocene catalyzed (Exxpol
process) Polyolefin with excellent elasticity
as well as good processability. Two new Vistamaxx
grades, VM-2125 and VM-2120, have been developed.
They have 80 MFR and density ranging from 0.865-0.868.
Both grades, besides offering good elasticity,
offer very good recovery. Both of them have
excellent processability. The main advantage
of these two grades is that they provide elasticity
to non wovens directly without any further modifications.
Last year Exxon had introduced a Metallocene
grade for melt blown process. With the latest
introduction of grades, Exxon now can offer
elastic grades for complete nonwoven process
For nonwoven converters using spunbond technology,
the latest Vistamaxx products offer an innovative
way to provide cost-effective elasticity in
nonwovens fabrics. They can be spun in most
spunbond lines to produce fabrics at typical
PP processing conditions and rates. Web properties
can be tailored by the selection of resin spinning
condition and downstream treatment, resulting
in fabrics over a wide range of elasticity that
are soft, drapeable and tear-resistant. In addition
to being compatible with a wide variety of polymers,
Vistamaxx can improve the elasticity, flexibility,
adhesion, softness and toughness of products.
