Rayon Fiber – The Basics of Man-made Fibers

The man-made Rayon fiber is worldwide produced with a world production of quite 4 million tons per annum. The staple is cellulose, one among the foremost useable natural polymers (wood pulp). within the first production step, the pulp is immersed in caustic soda to convert it to alkaline cellulose. After pressing and shredding the alkaline cellulose is aged to depolymerize. an answer to the compound is added to make viscose.

The crumbs are dissolved in caustic soda to get a viscous solution called “viscose”. After ripening, filtering, and degassing the viscose solution is pumped struggling through metal spinnerets submerged during a spin bath. the bathtub contains vitriol (to acidify the cellulose xanthate), sodium sulfate (for rapid coagulation), and zinc sulfate (to cross-link the cellulose molecules). By changing various process conditions and therefore the addition of chemicals all different quite a viscose fibers are made. the ultimate steps are drawing, washing, and bleaching.


We’ve seen how expensive silk is – for several years, chemists tried to create artificial silk that would be mass-produced more cheaply. the primary commercial production of artificial silk was within the US in 1911. This filament fiber was named rayon in 1924.

Rayon is formed of cellulose, which may be a fibrous chemical found altogether plants. Tree bark is formed of cellulose, then are the stringy parts of celery. Some rayon is formed from linter. The short cotton fibers left on cottonseeds after ginning.

The cellulose is first chemically treated in order that it becomes a liquid solution. the answer is forced through a spinneret, which resembles a high tech showerhead, and into a shower that turns it back to a solid – rayon filaments.

Properties & Uses

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

Rayon is usually utilized in fashion and residential furnishings, but the fiber is additionally found in sanitary products, diapers, and medical supplies.

Characteristics of Rayon Fiber and Products

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