About CBSE NCERT Solutions For Class 8 Science Chapter 3: Chapter Summary
Here, in this chapter, you will learn about different kinds of fibres, the sources from where they are obtained, and their characteristics. You will also study the names and uses of different kinds of plastics.
The clothes which we wear are made of fabrics. Fabrics are made from fibres obtained from natural or artificial resources. Fibres are also used for making a large variety of household materials such as ropes, buckets, furniture, containers, etc. Based on the manufacturing method of fabrics they are called Rayon, Nylon, Polyester, and Acrylic.
Natural Fibres: Fibres obtained from plants and animals are called natural fibres. For example, cotton, silk, wool, and jute are natural fibres.
Synthetic Fibres: Fibres obtained from chemical substance are called synthetic fibres. For example rayon, nylon, polyester, and acrylic are natural fibres.
Characteristics of Synthetic Fibres: Synthetic fibres have some advantages over natural fibres. They are listed as follows:
-Dry quickly
-Do not wrinkle
-Durable
-Less expensive
-Easy to maintain
What are Plastics?
Plastics are polymers. They are made from synthetic or semi-synthetic organic compounds that are malleable. They can also be moulded into solid objects.
Characteristics of Plastics: Here are the characteristics of different kinds of plastics:
– They can be easily moulded to any shape.
– Plastics can be recycled, reused, melted, or made into wires.
– Thermoplastic is a plastic that gets deformed on heating and can be easily bent. It is used for making toys, combs, or containers. For example PVC and polythene
– Thermosetting Plastic is a kind of plastic which once moulded cannot be softened by heating, e.g bakelite and melamine. Bakelite is used for making electrical switches and handles of utensils. Melamine is used for making floor tiles, kitchenware, etc.
– They are light in weight and have good strength. That is why plastic containers are used for storing water, dry food, milk, etc.
So, in this chapter, you will learn what are fibres, types of fibres, characteristics of fibres, types of plastics and their uses. After you have completed the chapter, you can revise it from the revision notes provided in this section.
