Converting of
nonwoven products often involves certain finishing
operations which can be performed either inline with the
converting machine or in an offline, roll-to-roll
finishing operation.
One common
web finishing technique is to emboss the material for
either decorative or functional purposes.
Another
common method of web finishing is to laminate a nonwoven
with other materials to achieve a specific desired
effect. Lamination with tissue can improve bulk,
increase absorbency and reduce overall costs. Scrim may
be laminated to nonwoven material as a means of greatly
increasing the strength of the material. If barrier
properties are required, lamination with a suitable
barrier film may meet the requirements of the intended
end use.
Numerous
printing processes are available as a mens of decorating
a nonwoven material or for including identification or
usage instructions on the finished product.
Another
finishing treatment is the coating of the nonwoven using
one out of the wide range of techniques utilised to
apply the coating.
Furthermore a
wide range of finishing treatments can be applied to
nonwoven webs to change properties. Examples are aqueous
fluid repellency, antimicrobial treatments, flame
retardant and
microencapsulation.
