Synthetic fibre are synthesised from raw material called as petrochemicals.

Synthetic Fibres Raw Materials
Synthetic fibres are created from raw materials known as polymers. These polymers are usually derived from petrochemicals, such as oil and natural gas. The raw materials undergo a series of chemical processes to create the synthetic fibres that we use in various products.

Types of Raw Materials for Synthetic Fibres
1. Polyester: One of the most common raw materials for synthetic fibres is polyester. It is made from a chemical reaction involving petroleum, coal, air, and water. Polyester fibres are known for their durability and resistance to wrinkles and shrinking.
2. Nylon: Another popular raw material for synthetic fibres is nylon. It is derived from petrochemicals and is known for its strength and elasticity. Nylon fibres are commonly used in clothing, carpets, and other textiles.
3. Acrylic: Acrylic fibres are made from acrylonitrile, a compound derived from petrochemicals. Acrylic fibres are soft, lightweight, and resistant to sunlight and chemicals. They are often used in clothing, upholstery, and outdoor fabrics.
4. Rayon: Rayon is a semi-synthetic fibre made from cellulose, which is extracted from wood pulp. Although rayon is not considered a fully synthetic fibre, it is often classified as one due to its chemical processing. Rayon fibres are soft, breathable, and versatile.

Chemical Processes
The raw materials undergo various chemical processes, such as polymerization, spinning, drawing, and finishing, to create the synthetic fibres. These processes involve heating, cooling, and stretching the polymers to form long, continuous fibres that can be woven into textiles.
In conclusion, synthetic fibres are created from raw materials like polyester, nylon, acrylic, and rayon, which undergo chemical processes to produce durable and versatile fibres for a wide range of applications.
