  1. Fibers and Fabrics Part Two The Details

  2. How it Works! • If you fray or unravel a scrap of fabric until you find a single thread or yarn, and then you untwist that thread or yarn until you have one single hair like strand then you are hanging on to a fiber. • Not all fibers can be made into fabric, a fiber must have certain properties that allow this process to be sucessful!

  3. Lesson Objectives • Describe fiber properties needed to construct into fabrics • Identify classifications of fibers • Explain how manufactured fibers are made • List various fibers and their characteristics

  4. Fibers for Fabrics: What’s Required? • Four essential properties: • 1. The fiber must be strong! • 2. The fiber must be pliable, bends without breaking! • 3. The fiber must have elasticity, or ability to stretch and return to its shape! • 4. The fiber must be long enough to be able to be spun into yarn or threads!

  5. Fiber Classification: • Natural: fibers that come from natural sources such as plants or animals. • Manufactured: fibers that result from scientific processes in the lab Note: • Generic names are used to describe different types of fibers such as: Cotton, wool, nylon, rayon, polyester etc. • Trade names are used to denote particular brands such as Darcon, Gutterman, etc.

  6. Natural Fibers • Composed of natural elements or resources. • Cotton, flax, ramie; are all examples of plant fibers that are made from the cellulose (fibrous substance found in plants) • Wool and silk are examples of animal fibers made from animal proteins • Examples: Cotton, Wool, Flax, Linen, Ramie, Jute, Silk, Rubber (Can be synthetic also).

  7. Manufactured Fibers • Manufactured fibers come from substances found in nature also but cannot be used in their original state they must be chemically engineered into fibers • Manufactured fibers have the advantage of being engineered with special qualities such as, colourfastness, flame resistance, water resistance, etc. • Also sometimes they are easier to care for • Examples: Rayon, Acetate, Triacetate, Nylon, Polyester, Acrylic, Olefin, Armid, Spandex, Glass, Metallic
