Yarn Types
Acetate – A man-made fiber derived from a cellulose base.
Acrylic – A synthetic fiber derived from a petrochemical base. It most resembles wool (resiliency, high
bulk, light weight), but because of flammability characteristics is seldom used in contract upholstery
fabrics.
Alpaca – The long, fine hair fiber obtained from the domesticated camel-like South American Alpaca. It
is classified as wool.
Angora – The silky hair of the Angora goat, native of Angora, a province of Turkey. Also known as
Mohair, the goat fiber is classified as wool.
Antron – DuPont’s trademarked term for tri-lobal nylon. A strong, delustred synthetic fiber.
Berber Yarn – A hand or machine spun wool characterized by its mottled, natural color and irregular
diameter.
Cellulose – A basic plant fiber found in cotton, flax, and wood. Chemically treated, it is the base for the
man-made fibers rayon and acetate.
Chenille – 1. A fuzzy, caterpillar-like yarn of either cotton or man-made fibers, produced by locking
short, cut fibers at right angles to the core thread
2. Fabric woven with chenille yarn in the weft, producing a cut-pile surface.
Cotton – A vegetable fiber composed of pure cellulose. It is soft and absorbent, and takes dyes and
special finished extremely well. Strong and durable, it has excellent resistance to pilling and abrasion.
Mercerization improves all these inherent qualities. Plain-weave cottons benefit particularly from the
applications of stain-repellent finishes.
Donegal Tweed – A thick, homespun woolen fabric, originally hand-woven in Donegal, Ireland. The
yarns are characteristically rough, with flecks of many colors.

Fiber – The most basic element in a cloth. Any tough, thread-like substance, natural or man-made, that
can be spun, woven, felted, knitted or knotted into a fabric.

thread of a silkworm’s cocoon; while man-made filament is produced by forcing a solution through a
spinneret.

and relatively low cost, which make it an ideal material for upholstery fabrics. However, nylon fabrics
have a tendency to pill and can attract soil because of static electricity.

abrasion.

and yarn.
Silk – The natural protein fiber unwound from the cocoon of the silkworm. Also, any fabric woven from
monofilament or spun-fiber silk yarns. Silk is noted for its strength, elasticity, affinity for dyes and high
cost.

thread passes alternatively under and over the warp yarns to produce a balanced construction. Also
known as Tabby, this is a strong weave, inexpensive to produce and the best ground for printing.
However, if the thread count is low, the fabric may be too weak for upholstery.

tunnel and ignited with a flame. The resulting flame spread rating determines whether the fabric is
categorized Class A (least flammable) or Class B.
