rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk

First Man-Made Fibre:

The first man-made fiber is known as rayon, also commonly referred to as "artificial silk." Rayon was developed as a substitute for natural silk during the late 19th century. It was the first successful semi-synthetic fiber created by humans.

History and Development:
- In the early 1800s, French chemist and industrialist Count Hilaire de Chardonnet experimented with developing synthetic fibers. He discovered that when cellulose, a natural polymer found in plants, was dissolved in a certain chemical solution, it could be spun into a fiber.
- Inspired by Chardonnet's work, other scientists began exploring the possibilities of creating artificial fibers from cellulose.
- In the 1890s, British chemists Charles Frederick Cross, Edward John Bevan, and Clayton Beadle developed a method to dissolve cellulose in a copper-ammonium solution, creating a viscous liquid.
- They then extruded this liquid through spinnerets, creating fine filaments that could be spun into threads.
- The resulting fiber was named "viscose" due to its viscous nature.
- Viscose, later renamed rayon, became commercially available by the late 1890s.

Properties and Characteristics:
- Rayon is versatile and can imitate the feel and texture of natural fibers such as silk, cotton, and linen.
- It is highly absorbent, making it comfortable to wear and suitable for warm weather.
- Rayon has good draping qualities, making it ideal for clothing that requires fluidity and movement.
- It can be easily dyed in various colors and prints.
- Rayon can be blended with other fibers to enhance its properties.

Significance and Uses:
- Rayon revolutionized the textile industry by providing an affordable alternative to natural silk.
- It became widely used in the production of clothing, including dresses, blouses, and underwear.
- Rayon is also utilized in home furnishings like curtains, upholstery, and beddings.
- Due to its absorbency, rayon is often used in the production of towels and bed linens.
- It has also found applications in medical products, industrial materials, and tire cords.

Conclusion:
Rayon, the first man-made fiber, was developed as an alternative to natural silk. Its discovery and subsequent commercialization had a significant impact on the textile industry. Rayon's versatility, comfort, and affordability have made it a popular choice for various applications, ranging from clothing to home furnishings.
