Production Method
There are two basic processes that are used in manufacturing metallic fibers. The most common is the laminating process, which seals a layer of aluminum between two layers of acetate or polyester film. These fibers are then cut into lengthwise strips for yarns and wound onto bobbins. The metal can be colored and sealed in a clear film, the adhesive can be colored, or the film can be colored before laminating. There are many different variations of color and effect that can be made in metallic fibers, producing a wide range of looks.
Metallic fibers can also be made by using the metalizing process. This process involves heating the metal until it vaporizes then depositing it at a high pressure onto the polyester film . This process produces thinner, more flexible, more durable, and more comfortable fibers.
Metal fiber may also be shaved from wire (steel wool), bundle drawn from larger diameter wire (smallest fiber is produced by this method), cast from molten metal, or grown around a seed (often carbon). Bundle drawn metal fiber can be produced to sizes smaller than one micrometre in diameter.

Famous quotes containing the words production and/or method:
“The repossession by women of our bodies will bring far more essential change to human society than the seizing of the means of production by workers.”
—Adrienne Rich (b. 1929)
“Unlike Descartes, we own and use our beliefs of the moment, even in the midst of philosophizing, until by what is vaguely called scientific method we change them here and there for the better. Within our own total evolving doctrine, we can judge truth as earnestly and absolutely as can be, subject to correction, but that goes without saying.”
—Willard Van Orman Quine (b. 1908)
