Stretchable Nonwovens

1. Stretchable Nonwovens

2. Nonwovens..
Low in cost
Flexible
Disposable

3. But have deficiencies in terms of,
 Aesthetics
 Drape
 Softness
 Elasticity

4. Movie On Elastic
Nonwoven

5.  It permits the fabric to expand and shrink
 for wipes and sanitary towels, allows a lot of
moisture to absorb
 For baby diapers, bandages and plasters it makes
the consumer comfortable since it permits the
movements of the body

6. Core
Sheath
Core: Extensibility
Sheath: Process ability

7.  Elastic component
Thermoplastic polyurethane
 Polyesters
 Ethers
Elastomeric polypropylene
 Sheath component
Extensible fiber, compatible with the elastic component
Provide haptics (sence of touch)

8. •Air/ electrostatic
power is used to
separate fibers
•Collected them
to a perforated
film and web is
made

9. Using blended fibers…
 Composition of the blended fiber to achieve the
extensibility as well as the aesthetic qualities
 Fiber, extruded resin SPE (Specialty Polyolefin
Elastomers)
 Manufactured web causes weaknesses in the
individual fiber breakages and weak points
 Due to difficulties in matching polymer types for
the blend
 Fibers are not longer enough

10. composite elastic nonwoven fabrics
 formed from the combination of a plurality
of cooperative elastic layers including an
elastomeric melt blown web and an
elastomeric spun bonded web.

11. Features
High absorption and fast drying
Soft in hand feel
Easily fitted for shapes desired
Looks like knitting in appearance
Applications
Medical materials
Baby cloth
Nursing Cushions
Industrial wipes
