Fibers
Basic Unit of all Textile Products- tiny
hair like.
 All fibers have their own characteristics
and properties, depending upon their
source, chemical composition, and
quality. No fiber is perfect. Each has
some good, fair, and poor qualities that
may make it suitable or unsuitable for
certain uses.

The basic characteristics of a fiber can be slightly
altered but never totally changed. The fiber may be
short, long, straight, or curly. These fiber
characteristics greatly affect the appearance, and
performance of the fabrics they are made into.
The Characteristics you look for in children’s clothing
is totally different that you would look for in evening
wear for yourself.
Thus an understanding of fibers, yarns, and fabrics if
basic to the study of apparel.
Yarns

Formed by a continuous strand of fibers
usually twisted together.
Fabrics

o
o
o
Are formed when yarns are combined.
Fabrics may be constructed using a
variety of different methods such as:
Weaving
Knitting
Felting
Fiber Sources

Natural- Plant or Animal fiber that grows in
nature. Two categories: Cellulosic Fibers
(plant), and Protein Fibers (animal). Include:
Cotton, Linen, Wool, Silk, Ramie, Hemp, Jute,
Bamboo, Leather
Fiber Sources (con’t)

Man-made- Made from a Natural material
called Cellulose. The cellulose is turned into a
liquid and poured through a spinneret.
Includes: Acetate, Rayon, Triacetate, Lyocell.
o Spinneret- Like a showerhead, that sprays
out chemicals that harden into long strands
called filament fibers.
Fiber Sources (con’t)

Synthetic- Made from chemicals,
petroleum, coal, and natural gas. All of these
fibers are manufactured from different
combinations of petroleum, natural gas, air
and water. They are poured through a
spinneret. Include: Acrylic, Polyester, Nylon,
Modacrylic, Spandex, and Olefin.
Fiber Structures

Staple Fibers- Short & Fuzzy- Usually
between 1” and 4” long. These tiny fibers
already exist in a plant or animal. The
fibers just need to be cleaned up, sorted,
and purified before they are used for
fabrics.
o Short
o Look lumpy and bumpy under a microscope
o Include all natural fibers, except silk
Fiber Structures (con’t)

Filament Fibers- Long and smooth (like
fishing line)
o Include all man-made, and synthetic fibers
o Include Silk
Spinneret- All man-made and Synthetic
fibers are poured through a Spinneret to
create the fiber.

Absorbent- able to take up moisture
Porous- able to breathe, air passes through
Biodegradable- able to break down
Most wrinkle easily
Tend to be more expensive
