Fiber Characteristics
Chapter 2
Fiber Sources
Natural Fibers
 Obtained
from plants or animals
 Plant Fibers
 Flax,
hemp, jute, ramie, cotton and kapok
 Animal
 Wool,
cashmere, mohair and silk
Manufactured Fibers
 Made
from chemical solutions that are forced
through tiny holes
 The device used to form the filaments is called a
Fiber Structure
Fiber Length
 Stable
fibers are measure in inches (all
manufactured fibers)
 Fibers of longer length are called filament
fibers (silk is the only natural one)
Fiber Shape
 Dogbone
 Flat, Oval with Convolutions
 Square with voids
 Serrated
 Round
 Trilobal
The ability to take in moisture
 It is usually expressed as a percentage
of moisture regain
 Fibers able to absorb water easily are
called hydrophilic fibers
 Fibers that have difficulty absorbing
water and are only able to absorb
small amounts are called hydrophobic
Fiber Absorbency
Skin Comfort
 Static Build-up
 Dimensional Stability in Water
 Stain Removal
 Water Repellency
 Wrinkle Recovery
The ability to occupy an area
The ability to increase in length when
under tension and then return to the
original length when released
The ability to ignite or burn
 Flammable fibers are relatively easy to
 Flame-resistant fibers have relatively
high ignition temperature and slow rate
of burning
 Flameproof fibers will not burn
The capability of a fiber to bend easily
and repeatedly without breaking
The way a fiber, yarn, or fabric feels
when handled
 It is affected by its shape, surface and
Refers to the light reflected from a
 Increased light reflection occurs from a
smoother surface, less crimp, flatter
cross-sectional shape, and longer fiber
The formation of groups of short or
broken fibers on the surface of a fabric
that are tangled together in the shape
of a tiny ball called a pill
 They are formed when the ends of a
fiber break from the fabric surface,
usually from wear
The capability of a material to spring
back in shape after being creased,
twisted, or distorted
Static Electricity
The frictional electric charge caused
by the rubbing together of two
dissimilar materials
A fiber’s ability to withstand stress
