Content:
These are the reasons and usefulness of textiles.
- Textiles are important for their utility value. They are used in a great variety of ways in our daily lives, from clothing to home furnishings, and in industrial and commercial applications.
- Textiles add comfort, warmth, and protection to our lives. They help us to maintain a comfortable body temperature and protect us from harsh weather conditions.
- Textiles provide support and cushioning. In addition to their utility value, textiles also play an important role in our lives as a source of aesthetic pleasure. The colors, textures, and patterns of textile fabrics can add beauty and interest to our surroundings.
- Textiles are also a significant source of employment and income for many people around the world. The textile industry is a major contributor to the economies of many countries.

Differences between Natural and Synthetic Fibres
Natural fibres are made from plants or animals, while synthetic fibres are man-made. Natural fibres are usually stronger and more durable than synthetic fibres, but they can be more expensive. Cotton is a natural fibre that is often used to make clothing, while polyester is a synthetic fibre that is often used to make furniture.
Classification of Fibres
There are many different types of natural and synthetic fibres, each with its own set of properties. Natural fibres are usually classified by their source, while synthetic fibres are classified by their chemical structure.
Cotton is a natural fibre that comes from the cotton plant. It is a soft fibre that is often used to make clothing.
Linen is a natural fibre that comes from the flax plant. It is a strong fibre that is often used to make tablecloths and napkins.
Wool is a natural fibre that comes from sheep. It is a warm fibre that is often used to make sweaters.
Silk is a natural fibre that comes from silkworms. It is a smooth fibre that is often used to make ties and dresses.
Polyester is a synthetic fibre that is made from a long chain of polyethylene molecules. It is a strong fibre that is often used to make furniture.
Nylon is a synthetic fibre that is made from a long chain of nylon
Properties of Cotton
Cotton is a natural fibre that comes from the cotton plant. It is a soft fibre that is often used to make clothing. Cotton is a strong, durable fibre, but it can shrink when it is washed in hot water.
Linen is a natural fibre that comes from the flax plant. It is a strong fibre that is often used to make tablecloths and napkins. Linen is a strong, durable fibre, but it can wrinkle easily.
Wool is a natural fibre that comes from sheep. It is a warm fibre that is often used to make sweaters. Wool is a warm, insulating fibre, but it can be uncomfortable to wear.
Properties of Fibres
Each type of fibre has its own unique set of properties. These properties determine how the fibre can be used. Natural fibres are usually stronger and more durable than synthetic fibres, but they can be more expensive. Cotton is a natural fibre that is often used to make clothing, while polyester is a synthetic fibre that is often used to make furniture.
When choosing a fibre for a specific purpose, it is important to consider the properties of the fibre. Some of the most important properties of fibres include:
– Strength
– Durability
– Flexibility
– Softness
– absorbency
– Static resistance
– Heat resistance
– Light resistance
– Colourfastness
Properties of Linen
Linen is a natural fibre that comes from the flax plant. It is a strong, durable fibre that is often used to make tablecloths and napkins. Linen is a absorbent fibre, but it can wrinkle easily. Linen is a light-resistant fibre, but it is not as colourfast as some other fibres.
Properties of Wool
Wool is a natural fibre that comes from sheep. It is a warm, insulating fibre that is often used to make sweaters. Wool is a absorbent fibre, but it can be uncomfortable to wear. Wool is a fire-resistant fibre, but it is not as colourfast as some other fibres.
Properties of silk
Silk is a natural fiber that comes from silkworms. It is a smooth fiber used to make ties and dresses. Silk is strong, but it can be damaged by sunlight. Silk is absorbent and static resistant, but it is not as colorfast as some other fibers.
Properties or Characteristics of Man-made or Synthetic Fibres
Man-made or synthetic fibres are classified according to their chemical structure. The two most common types of synthetic fibres are polyester and nylon.
Polyester is a strong, durable fibre that is often used to make furniture. Polyester is a static-resistant fibre, but it is not as colourfast as some other fibres.
Nylon is a strong, durable fibre that is often used to make clothing. Nylon is a static-resistant fibre, but it is not as colourfast as some other fibres.
When choosing a man-made or synthetic fibre for a specific purpose, it is important to consider the properties of the fibre. Some of the most important properties of synthetic fibres include:
– Strength
– Durability
– Flexibility
– Static resistance
– Heat resistance
– Light resistance
– Colourfastness
Properties of Viscose Rayon
Viscose rayon is a man-made fibre that is made from wood pulp. It is a absorbent fibre that is often used to make clothing. Viscose rayon is a static-resistant fibre, but it is not as colourfast as some other fibres.
Viscose rayon is a strong, durable fibre, but it can shrink when it is washed in hot water.
Properties of viscose ray
– Strong
– Durable
– Absorbent
– Static resistant
– Shrinks in hot water
Properties of Acetate
Acetate is a synthetic fibre made from cellulose. It is a smooth, lustrous fibre that is often used to make clothing. Acetate is a absorbent fibre, but it is not as colourfast as some other fibres. Acetate is a strong, durable fibre, but it can shrink when it is washed
Write out ten properties of Acetate
– Strong
– Durable
– Smooth
– Absorbent
– Lustrous
– Static resistant
– Heat resistant
– Light resistant
– Colourfast
– Shrinks when wet
Properties of Nylon
Nylon is a strong, durable synthetic fibre that is often used to make clothing. It is resistant to static and heat, but it is not as colourfast as some other fibres. Nylon can shrink when it is washed in hot water.
Write out ten Properties of Nylon
– Strong
– Durable
– Synthetic
– Static resistant
– Heat resistant
– Light resistant
– Colourfast
– Shrinks when wet
– Fire resistant
– Chemically resistant
Properties of Polyester
Polyester is a type of synthetic fibre. It is made from long chains of polymers. Polyester is a strong, durable fibre that is often used to make clothing and furniture. Polyester is a static-resistant fibre, but it is not as colourfast as some other fibres. Polyester can shrink when it is washed in hot water.
Ten properties of Polyester
– Strong
– Durable
– Synthetic
– Static resistant
– Heat resistant
– Light resistant
– Colourfast
– Shrinks when wet
– Fire or heat resistant
– Chemically resistant
Criteria for different types of fabrics
– How strong is the fabric?
