|
Wool
|
fleece of sheep, one of the best natural fibers. Excellent resilience, elasticity, resistant to soiling, wears well, cleans easily, self-extinguishing when flame is removed can be stretched; low dimensional stability.
|
|
|
Acrylic
|
Typical replacement for wool - aesthetics. Verry resistant to sunlight, moderate strength & resilience. Can be flammable.
|
|
|
Cotton
|
Cellulosic fiber, good tensile strength poor resilience & recovery, degrades under prolonged sun exposure, burns readily; suject to mildew.
|
|
|
Linen
|
Bast fiber - derived from stalk flax plant short staple fibers dimensionally stable, not upholstery - lacks resilience and flexibility, Used for draperies and wallcoverings.
|
|
|
Rayon
|
regenerated cellulosic fiber, poor resistance to sun & poor resiliency. Low resistnat to water and moisture. Flammable, not for upholstery.
|
|
|
Acetate
|
regenerated cellulosic fiber - chemicals. Flammable, poor sunlight resistance, does not wear well.
|
|
|
Nylon
|
Synthetic fiber, strong, high resiliency and elasticity, often combined with natural fibers.
|
|
|
Olefin
|
Inexpensive, high resistance to chemicals, mildew, microorganisms. Carpet and backing, not upholstery.
|
|
|
Polyester
|
good resilience & elasticity, high resistance to solvents, chemicals, sunlight. Absorbs oily materials. can be treated for flame-resistance.

-Polyester Batting -Smolder & flame resistant polyurethane foam. -Smolder & flame resistant cellulosic batting -Mixed fiber batting -Untreated polyurethane foam -Cellulosic batting -Latex foam (rarely used) |
|
|
Foam cushions: perfomance criteria
|
-Density (support)
-Indentation Load Deflection (support) -Support ration (foce required to compress) |
|
|
Fading Test (fabrics)
|
Fadeometer - exposes fabrics to UV light at specific humidity levels
Tests color loss in 20 hr intervals. 80 hrs = mon. |
