Manufacturing

We’ve seen how expensive silk is – for many years, chemists tried to invent artificial silk that could be mass-produced more cheaply. The first commercial production of artificial silk was in the United States in 1911. This filament fiber was named rayon in 1924.

Rayon is made of cellulose, which is a fibrous chemical found in all plants. Tree bark is made of cellulose, and so are the stringy parts of celery. Some rayon is made from linters, the short cotton fibers left on cottonseeds after ginning.

The cellulose is first chemically treated so that it becomes a liquid solution. The solution is forced through a spinneret, which resembles a high tech showerhead, and into a bath that turns it back into a solid – rayon filaments.



Properties & Uses

Although rayon was first invented as artificial silk, it can also be made to resemble cotton, linen or wool. Because rayon is made from vegetable matter, it absorbs water. But absorbing water makes rayon weak and causes the fiber to break.

Rayon is often used in fashion and home furnishings, but the fiber is also found in sanitary products, diapers, and medical supplies.

Characteristics of Rayon Fibers and Products

  • A cellulosic fiber usually made from wood pulp
  • First manufactured fiber. Produced in 1911 but first known as "artificial silk"
  • Stretches and shrinks more than cotton
  • Poor abrasion resistance (easily damaged by scraping)
  • Loses strength when wet
  • Highly absorbent and dyes easily
  • Best to dry clean or wash carefully because of shrinkage
  • Fairly expensive
  • Synthetic Fibers from Petrochemicals

Review

  • Rayon first used commercially in 1911.
  • Rayon is made of cellulose, which is found in all plants.
  • Although, the fiber was created as an artificial silk, it can also resemble cotton, linen and wool.
