Wool
used for carpets, upholstery and drapery
resilient
great elasticity
cleans easily
self extinguishing
expensive
not as stable since it can be stretched
Cotton
natural fiber
inexpensive
good strength
moderate abrasion resistance
poor resilience
burns readily
subject to mildew
Linen
mostly used for draperies and wall coverings
natural fiber
lacks resilience and flexibility
susceptible to abrasion
does not take printed dyes well
Silk
Natural fiber
strong
good resilience and flexibility
expensive
degrades in sunlight
Rayon
mostly used for upholstery
high absorbency
poor sunlight resistance
poor resiliency
low resistance to water and moisture
flammable
Nylon
synthetic fiber
strong
high resilience and elasticity
resistant to many chemicals and water
Polyester
synthetic fiber
good resilience and elasticity
high resistance to solvents and chemicals
undesirable burning properties
smoldering resistance
cigarette ignition resistance test for upholstery
Indentation Load Deflection (ILD)
the # of pounds it takes to compress the foam down to 1” or 25%
Vertical ignition test
establishes two procedures for testing the flammability of draperies, curtains, and other window treatments
Cigarette Ignition Resistance Test of Furniture Components
tests the resistance of upholstered furniture components separately, to flame and cigarette ignition
Cigarette Ignition Resistance Test of Furniture Composites
ests the resistance of a seat cushion mockup (including foam, liner, and fabric) to a lighted cigarette
Full seating test
test evaluates the effect of an open flame on an actual sample of a chair
wool carpet fibers
natural, durable, wears well, flame resistant, easy to clean
nylon carpet fibers
strong, wear-resistant, good stain and crush resistance, most widely used
Acrylic carpet Fibers
moderate abrasion resistance, good crush resistance, easy to maintain
polyester carpet fibers
synthetic, high abrasion resistant, good crush resistance, cleans well, low in cost
