PRODUCERS
These fibers contain two components lying side-by-
side. Generally, these fibers consist of two
components divided along the length into two or
more distinct regions.
Sheath-core Bicomponent
fibers are those fibers where
one of the componentsis fully
surrounded by the second
component.
These fibers are widely used
as bonding fibers in
Nonwoven industry.
