__//**Manufactured Fibers**//__

"Manufactured fibers are man-made fibers that do not exist in this form in nature. The fiber is created using a spinning mass that is extruded through holes by the application of even pressure. A distinction is made between natural polymers, such as viscose or Lyocell, and synthetic polymers, such as polyester or polyamide. Natural polymers are manufactured using a product of nature - cellulose. It is chemically treated to convert it into spinning mass and can then be spun. Crude oil is the principle raw material used in the manufacture of synthetic chemical fibers. Here again, the fiber is created after production of the spinning mass (Hessnatur, 2011)."

**//__List of Manufactured Fibers__//** These are the three manufactured fibers that I feel are important.
 * **Acetate**
 * **Acrylic **
 * **Aramids **
 * **Lyocell **
 * **Nylon **
 * **Microfiber **
 * **Polyester **
 * **Rayon**

__//**Microfiber**//__ "Manufactured fibers are now being produced with the feel, look, and drapability of the most expensive silk....Its use is growing rapidly in the apparel industry, due to its luxurious feel, ease of care, strength, and comfort (Manufactured Fibers Uses)." Microfiber commonly refers to any fiber with strand less than 1 denier. Microfibers are finer and thinner then silk and any other natural fiber.

**//__Polyester__//** Polyester is the most highly sold manufactured fiber. One reason why polyester is so popular is because it can easily blend with other fibers, like; cotton, wool, and rayon. Polyesters are generally manufactured from petroleum from which the constituent acids and alcohols are derived. The fabric and fiber of polyester is very strong and of a hydrophobic nature. "Polyester retains its shape and hence is good for making outdoor clothing for harsh climates (What Is Polyester)." Unlike wool and cotton, polyester has built in insulation which keeps the warm air in.

**__Nylon__**

// **__Characteristics__** //
 * Exceptionally strong
 * Elastic
 * Abrasion resistant
 * Lustrous
 * Easy to wash
 * Resistant to damage from oil and many chemicals
 * Can be precolored or dyed in wide range of colors
 * Resilient
 * Low in moisture absorbency
 * Filament yarns provide smooth, soft, long-lasting fabrics
 * Spun yarns lend fabrics light weight and warmth
