Definition of Synthetic Fiber

A synthetic fiber is a chain of small units joined together
OR
A synthetic fiber is any fiber made by extruding a synthetic substance through spinnerets to make a thread. Synthetic fiber can also be defined as any non-organic fiber used in rope or cordage manufacture

More About Synthetic Fiber

  • Many small units of which synthetic fiber is comprised of combine to form a large unit called ‘polymer’
  • Polymers occur in nature also
  • There are many types of synthetic fibers
  • Synthetic fibers are made by chemical processes, unknown in nature
  • Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers
  • Synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes, forming a thread
  • A synthetic fiber looks like plastic spun together
  • The fabric is made from chemically spun fibers
  • The first synthetic fiber in the early 1880s. This fiber was drawn from a cellulose liquid, formed by chemically modifying the fiber contained in tree bark
  • It was invented by sir Joseph Swan
  • The synthetic fiber produced was similar to “Carbon filament”
  • Man-made fibers are fibers in which either the basic chemical units have been formed by chemical synthesis followed by fiber formation or the polymers from natural sources
  • The polymers have been dissolved and regenerated after passage through a spinneret to form fibers
  • The researchers obtained a product by condensation of product presenting two reactive amino groups with molecules charactised by two carboxyl groups
  • Synthetic fibers do not depend upon agricultural crops or on animal farming
  • They are cheaper than natural fiber
  • Synthetic fibers are easy to wash and dry up quickly
  • Synthetic fibers are more stain resistant than natural fibers
  • Resistant to insects, fungi and rot
  • With synthetic fibers one can create waterproof fabrics and elastic/stretchy fabrics for swimwear and lingerie
  • Depending on the fabric, other chemicals are added to make the fabric softer, wrinkle free, flame-resistant, water resistant, stain-resistant, and moth-repellent
  • The processes used to make synthetic fibers and fabrics can have harmful effects on the environment, wildlife and people's health.
