Introduction to Fibre and Fabric

Fibres and fabrics play a vital role in our daily lives, as they are used to make clothing, household items, and industrial materials. Fibres are the basic building blocks of fabrics, which are woven or knitted to create textiles used in various applications.

What are Fibres?

Fibres are thin, thread-like strands that are spun to form yarn, which is then used to make fabrics. These fibres can be classified into two main categories:

  1. Natural Fibres – Obtained from plants, animals, or minerals. Examples include cotton, wool, silk, and linen.
  2. Synthetic Fibres – Manufactured from chemicals and petroleum-based products. Examples include nylon, polyester, and acrylic.

Difference Between Natural and Synthetic Fibres

Feature Natural Fibres Synthetic Fibres
Source Derived from plants or animals Made from petrochemicals
Examples Cotton, wool, silk, jute Nylon, polyester, acrylic
Comfort Soft, breathable Less breathable, may cause sweating
Durability Less durable, affected by pests More durable, resistant to pests
Eco-friendliness Biodegradable, eco-friendly Non-biodegradable, may cause pollution
Maintenance Requires special care (e.g., wool shrinks) Easy to wash and maintain

Importance of Fabrics in Daily Life

Fabrics are an essential part of human life, serving multiple purposes, such as:

  1. Clothing: Used to make clothes for protection, comfort, and fashion.
  2. Household Items: Used in making curtains, bedsheets, towels, and upholstery.
  3. Industrial Uses: Used in making parachutes, tents, ropes, and safety gear.
  4. Medical Applications: Used in making bandages, masks, and surgical gowns.
  5. Sports and Adventure Gear: Used in making sportswear, swimwear, and trekking gear.
