					FIBERS TO FABRICS
Fiber is a hairlike strand of material. It is a
substance that is extremely long in
relation to its width, at least 100 times
longer than it is wide. A fiber is the
smallest visible unit of any textile product.
Fibers are flexible and may be spun into
yarn and made into fabrics.
There are two categories of fibers:
                  Natural
           Manmade (synthetic)
Natural Fibers
   Cotton
    Wool
    Flax
    Silk
Cotton
       This is what cotton fiber looks like under the microscope




Note that it is made up of many layers. It is not straight.
Wool
       This is what wool fiber looks like under the microscope




Note that the fiber is not smooth.
Flax
Flax or linen fiber under the microscope
Silk
                   Silk fiber under the microscope




Note that it is smooth compared to wool and cotton.
                Manmade Fibers
   Synthetic fibers are the result of extensive research by
    scientists to improve on naturally occurring animal and
    plant fibers. In general, synthetic fibers are created by
    forcing, usually through extrusion, fiber forming
    materials through holes (called spinnerets) into the air,
    forming a thread.

   Synthetic Fibers are made from synthesized polymers or
    small molecules. The compounds that are used to make
    these fibers come from raw materials such as petroleum
    based chemicals or petrochemicals.
Common synthetic fibers include:
Rayon
Acetate
Nylon
Acrylic
Polyester
Spandex         there are more
Comparison of natural fibers to synthetic (polyester, the last one) under the
                                 microscope
                FABRICS
Fibers are spun into yarns or threads.
Fibers can be made into fabric in 3 ways:

WOVEN
KNIT
NONWOVEN
WOVEN
KNIT
NONWOVEN
The characteristics of any given fabric is
  related to it properties as a fiber.
Fibers can also be blended to take
  advantages of the properties of each fiber.

Example: Polyester may be blended with
  cotton.
Fibers are a part of our life that we take for granted.
       What would your life be without them?
