Concept:

• Fibres are long, thin, and flexible thread-like structures. 
• Fibres are classified into two types based on their origin: natural fibres and synthetic fibres.

   • Natural fibres are obtained from plants and animals.
   • Natural fibres are further classified into two types:
     • Plant fibres- Plant fibres are derived from plants.
       • Example: Cotton and Jute
     • Animal fibres- Animal fibres are derived from animals.
       • Example: Silk and Wool
2. Synthetic fibres-

   • Example: Rayon and Nylon

Explanation:

• We usually wear woollen clothes in winter. 
• Wool is the preferred fabric for winter clothing. 
• As wool is a bad conductor of heat, it insulates the body from the surrounding. 
• Furthermore, the air trapped between the wool fibres prevents the flow of heat from our bodies to cool surroundings.​
• Winter clothes are especially outerwear like coats, jackets, hats, scarves and gloves or mittens, mufflers.
• Many of these are actually not made from natural wool, though they appear to resemble wool. 
• These are prepared from another type of synthetic fibre called acrylic.
• The wool obtained from natural sources is quite expensive, whereas clothes made from acrylic are relatively cheap.

Additional Information

• We use raincoats, gumboots, and umbrellas to keep dry during the rainy season.
