Natural Fibres

Fibre to Fabric I - Concepts

Class - 6th CBSE Subjects

Concept Explanation

Natural Fibres

Fibres that are obtained from plants and animals are called natural fibres.

Cotton, jute, coir, hemp and flax are examples of fibres obtained from plants. Wool and silk fibres are obtained from animals.

Wool is obtained from the fleece of sheep or goats. It is also obtained from the hair of rabbits, yaks and camels.

Silk fibre is drawn from the cocoon of the silkworm. The fabric made from natural fibres is called natural fabric.

Advantages of natural fibres:-

These fabrics absorb more water and sweat.

They allow air to pass through them.

They are biodegradable and do not affect the environment.

Disadvantages of natural fibres:-

They do not retain their creases for long.

They may shrink on ordinary washing.

They can easily be attacked by moths and moulds.

They do not dry rapidly.

Natural silk is very expensive and not quite affordable.

Explanation

Fibres are materials which are usually thin and have a thread-like structure. They are generally classified as natural and synthetic, on the basis of their origin. Natural fibres may be plant fibres like cotton or animal fibres like wool.

Natural Fibres: These are derived from natural sources such as plants and animals. They have been used by humans for thousands of years. Examples of natural plant fibres include cotton, jute, and hemp, while examples of natural animal fibres include wool (from sheep), silk (from silkworms), and cashmere (from goats). These fibres are biodegradable and renewable, making them environmentally friendly in many cases.
Synthetic Fibres: These are man-made fibres produced from chemical substances. They are typically derived from petrochemicals or polymers. Examples of synthetic fibres include polyester, nylon, acrylic, and spandex. Synthetic fibres are often engineered to possess specific properties such as strength, durability, and resistance to wrinkles and moisture. They are commonly used in various applications including clothing, upholstery, and industrial materials.
Cotton: Cotton is a natural plant fibre harvested from the cotton plant's seed pods. It is soft, breathable, and comfortable to wear, making it a popular choice for clothing, bedding, and towels. Cotton fibres are composed primarily of cellulose, a carbohydrate polymer.
Wool: Wool is a natural animal fibre obtained from the fleece of sheep and other animals such as goats (cashmere, mohair), alpacas, and rabbits (angora). It is known for its warmth, insulation properties, and elasticity. Wool fibres have a crimped structure, which creates tiny air pockets that trap heat, making wool garments ideal for cold weather conditions.

In summary, fibres play a crucial role in various industries and applications, ranging from textiles and fashion to household goods and industrial products. Understanding the differences between natural and synthetic fibres helps in choosing materials that best suit specific needs and preferences.
