Synthetic Fibers & Plastics – 03
Synthetic fibers and synthetic fabrics are used in a variety of industries and applications, including:
- Apparel or clothing
- Architecture and construction
- Automotive and transportation
- Chemical processing
- Plastic is also a polymer like The Synthetic Fibre. All plastics do not have the same type of arrangement of units. In some it is linear, whereas in others it is cross-linked.
- Plastic articles are available in all possible shapes and sizes. The fact is that plastic is easily Mouldable i.e. can be shaped in any form. Plastic can be Recycled, Reused, Coloured, Melted, Rolled into sheets or made into wires. That is why it finds such a variety of uses.
- Polythene (Poly+ethene) is an example of a plastic. It is used for making commonly used POLYTHENE BAGS.
- We will observe that some plastic articles can bend easily while some break when forced to bend. When we add hot water to a plastic bottle, it gets deformed. Such plastic which gets deformed easily on heating and can be bent easily are KNOWN AS THERMOPLASTICS. Polythene and PVC are some of the examples of thermoplastics. These are used for manufacturing TOYS, COMBS AND VARIOUS TYPES OF CONTAINERS.
- On the other hand, there are some plastics which when moulded once, cannot be softened by heating. These are called thermosetting plastics. Two examples are BAKELITE AND MELAMINE. Bakelite is a poor conductor of heat and electricity. It is used for making electrical switches, handles of various utensils, etc. MELAMINE is a versatile material. It resists fire and can tolerate heat better than other plastics. It is used for making FLOOR TILES, KITCHENWARE AND FABRICS which resist fire.
