Fabric Applications
The following describes some of the key
applications for engineered nonwoven fabrics by the furnishings and bedding industries.
Upholstered
Furniture Applications
Dust covers on the bottom of upholstered chairs and sofas
are generally made from spunbonded polypropylene or polyester materials. These
fabrics, generally black, hide the internal seating construction and prevent
house pets or insects from penetrating the upholstered furniture from below.
Decking fabrics are
the materials under the loose seat cushions. Engineered nonwoven fabrics are
often used to replace the higher cost outer fabric. These nonwoven fabrics are
usually white but can be colored to coordinate with the upholstered furniture's
outer fabric. These fabrics are relatively heavy, in the 100-135 grams/meter² range,
as they must be strong enough to withstand stretching forces and hold sewing
stitches and construction staples.
Cushion and pillow inserts hold the
stuffing, such as fiberfill or feathers together to prevent leakage and allow
the user to clean or replace the outer fabric. Engineered nonwoven fabrics have
captured a high level of penetration by replacing woven cotton materials. Spunbonded
materials in this application are usually 40-50 grams/meter².
Spring
insulators are often made of needlepunched nonwoven materials. Needlepunched
nonwovens are relatively abrasion resistant and have the strength to hold staples
that fasten the upholstery to the wood frame.
Upholstered arm and seat are
covered with engineered nonwoven fabrics to provide support for the foam or other
cushioning materials covering the wooden frame. These nonwoven fabrics must be
strong enough to hold construction staples.
Tailored skirts are found
on some upholstered sofas and chairs. Spunbonded polyester nonwoven fabrics can
be sewn or bonded to the face material providing stiffness or to retain pleats.
Pull
Strips are often made from narrow strips of engineered nonwoven materials
that are sewn to the upholstery fabrics. The upholsterer uses these strips to
pull the fabrics tightly over springs and fasten the material to the wooden frame.
Engineered nonwoven fabrics compete with a wide assortment of other materials
and must be strong enough to hold the stitching and staples. Often fabric scraps
are in this end-use.
Bedding
Applications
Quilt backing used in bedding construction is one of the larger end-uses
for engineered nonwoven fabrics. Nonwoven fabrics are the backing material to
which the mattress ticking and foam or fiberfill is quilted. The quilted nonwoven
mattress ticking must be strong enough to resist tearing after sewing the mattress
top and bottom to the mattress side panels or flanges. Weights of non-woven fabrics
used here vary widely with weights as low 10-15 grams/ meter² and range
up to almost 50 grams/meter² where more "puff" is desired in the quilt.
Flanges are
the panels of material that surrounds the edge of the mattress and join the mattress
top and bottom together. Medium weight spunbonded materials, generally is wrapped
individually so that it can function separately and quietly. Needlepunched material
is favored because it resists abrasion, has adequate strength and is heat sealable.
Mattress
Ticking used on inexpensive mattresses is occasionally made from printed
spunbonded polypropylene. Good stability, strength and the ability to accept
a print are the key requirements for this application.
Insulators made
of various types of engineered nonwoven fabrics are used in mattress construction
to cover springs. Needlepunched material is often found here and must have sufficient
strength to be fastened into place and resist abrasion.
Other Applications
Protective mattress pads are generally quilted and use large volumes of
spunbonded nonwoven fabrics as facing and backing materials. In this application,
nonwoven fabrics have captured about half of the total volume and compete directly
with woven cottons. Spunbonded polyester is often used as it is strong and retains
its shape during laundering. Facing fabrics are generally 42-65 grams/meter²,
while backing fabrics are usually in the 15-20 grams/ meter² range.
