Faille  A flat, ribbed fabric woven with fine yarns in the warp, with heavier yarns in the filling, using a plain weave.  The ribbed effect is flatter than grosgrain and smaller than repp.  The fabric is the base cloth used for Moire.

Fiber  Any tough substance, natural or manmade, composed of thread like tissue capable of being made into yarn.

Fiber Base  Most man-made fibers are formed by forcing a syrupy substance (about the consistency of honey) through the tiny holes of a device called spinneret.  In their original state, the fiber forming substances exist as solids and therefore must be first converted into a liquid state for extrusion.  This is achieved by dissolving them in a solvent or melting them with heat.  If they cannot be dissolved or melted directly, they must be chemically converted into soluble derivatives.  The basic substance for the three cellulosic fibers (acetate, rayon, and triacetate)  is cellulose, which comes from purified wood pulp.  It can be dissolved for extrusion into fibers.  The substances used in the production of the noncellulosic fibers generally are melted or chemically converted into liquid state.

Fiber Content  The makeup of  the yarn content of  any given fabric (i.e., 60% cotton and 40% rayon).  By regulation of  the Federal Trade Comission, this information must be provided in all price lists.

Fiber Types 

a.  Natural Fibers:  Cotton* Wool* Silk* Linen* Hemp

b. Man-Made Fibers-Generic Classification:  Acetate*Acrylic*Glass*Modacrylic*Nylon*Olefin*Polyester*Rayon*Saran*Spandex*Vinyl

Fibers-Generic Definitions 

Acetate- A man-made fiber with a luxurious feeling, which dyes in brilliant colors, and is economical.  But it offers low resistance to wear and only fair resistance to sunlight.  When blended with other fibers, it can add beauty and luster to a fabric.  Acetate is seldom used in today's fabrics.

Acetate Ingredients- A manufactured fiber in which the fiber forming substance is cellulose acetate.  Where not less than 92% of the dydroxyl groups are acetylated, the term triacetate may be used as a generic description of the fiber.

Acrylic- A man made fiber with soft feeling: outstanding durability, excellent resistance to sunlight.  It has excellent cleanability characteristics and takes vivid color well.  Acrylic is normally used to create velvet and plush looks in fabrics and carpets.

Acrylic Ingredients- A manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed of at least 85% by weight of acrylonitrile units.

   Cotton-  Vegetable fiber, perhaps man's oldest; fair resistance to wear and sunlight; a soft feeling, dyes well, poor resistance to soil unless treated.

    Nylon-  A man made fiber, considered the strongest synthetic for upholstery fabrics, offering the best resistance to abrasion and soil; offers a cool soft feeling.  Good cleanability characteristics.

Nylon Ingredients-  A manufactured fiber in which the fiber forming substance is a long chain synthetic polyamide in which is less than 85% of the amide.

Olefin - Another strong man made fiber giving resistance to abrasion and stain resistance to fading when solution dyed, very sensitive to heat.

Olefin Ingredients- A manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed of at least 85% by weight of ethylene, propylene, or other olefin units.

Polyester- A man made fiber, crisp and strong, excellent resistance to wear and sunlight.  Most like natural cotton in its appearance and physical properties.

Polyester Ingredients- A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalate units.

Rayon- An economical man made fiber, soft feeling , dyes well, fair resistance to wear and sunlight.

Rayon Ingredients- A manufactured fiber composed of regenerated cellulose, as well as manufactured fibers composed of regenerated cellulose in which substituents have replaced not more than 15% of the hydrogens of the hydroxyl groups.

Fiberglass  Fibers and yarns produced from glass and woven into flexible fabrics. Noted for its fireproof qualities.

Finished Goods  Fabric that has been processed by dyeing, printing, applying of special resins and finishes, and is ready for market.

Finishing  The process of dyeing, printing, etc. of greige goods.

Finishing Plant  A place that dyes, prints, etc. , greige goods.
