Nonwovens are capturing a large share of the disposable market (diapers, surgical gowns, cleaning cloths (Swiffer, etc), Handi-wipes.
Nonwoven fabrics are usually "made from
extruded filaments or from fiber webs or batts
strengthened by bonding using various techniques;
these include adhesive bonding,
mechanical interlocking by needling or
fluid jet entanglement, thermal bonding, and stitch
bonding."
Nonwoven fabrics are made by bonding the
fibers either by heat, moisture and heat, an
adhesive, or a combination.
nonwoven fabrics are usually more stiff
than woven or knitted fabrics.Often they are used for
stabilization or for disposable products.
Dry-laid nonwovens -nonwovens containing
layers of fibers, each layer containing randomly
positioned or parallel fibers. Bonding
with an adhesive or heat is necessary.
Wet-laid nonwovens - paper-like nonwovens
containing a random array of layered fibers,
with the layering resulting from the deposition
of fibers from a water slurry.
Needlepunched nonwovens are characterized
by the entangled condition of fibers of which
they are composed, with the entnaglement
resulting from the application of heat, moisture
and agitation to a fibrous web.
Spunlaced nonwovens have fibers entangled by action of high-velocity water jets.
