VR Tour For Std. 8 Ch. 3. Synthetic Fibers and Plastics
What's Included in Virtual tour of this chapter
Polymer means many monomers. A monomer is a single molecule that makes bonds with other identical molecules to form polymers through a Polymerization process. A monomer repeats itself many times to form extremely long chains which form the polymer. We will also understand the type of synthetic fibers and their uses. Plastic is easily moldable and is shaped in any form. Plastic can be recycled, reused, colored, melted, and rolled into sheets. Here, we will learn about the types of plastics.
Virtual tour 1: Polymer: Introduction and Classification Based on Availability Source and Structure of Monomer Chain
There are natural fiber, synthetic fiber, and plastic. Natural fibers are produced by plants and animals. Synthetic fibers or man-made fibers are textile fibers which is made by humans using natural materials and petrochemicals. Plastic is also a polymer. There are 4 types of polymer structures, linear polymer, a branched polymer, cross-linked polymer, and network polymers. We will study them in this virtual tour activity.
Virtual tour 2: Synthetic Fibers: Introduction and Types
In this virtual tour, we will learn about different types of synthetic fibers like rayon, nylon, polyester, and acrylic. Rayon is also known as artificial silk. Nylon is a fully synthetic fiber to be prepared without using any natural raw materials whereas polyester is made from petroleum, water, coal, and air.
Virtual tour 3: Plastic: Introduction and Types
In this virtual tour, we will learn about thermoplastic and thermosetting plastic. Thermoplastic materials are strong and lightweight plastic, but it can deform when we heat them. Plastic that cannot be softened by heating is known as thermosetting plastic. They are a poor conductor of heat. It is used to make fire-resisting materials.
