FAQs on Fibres to Clothes Video Lecture - Our Wondrous World Class 5 - New NCERT

1. What are the main types of fibers used to make clothes?
Ans. The main types of fibers used to make clothes can be categorized into two groups: natural fibers and synthetic fibers. Natural fibers come from plants or animals. Common examples include cotton (from cotton plants), wool (from sheep), and silk (from silkworms). Synthetic fibers, on the other hand, are man-made and include materials like polyester, nylon, and acrylic, which are produced through chemical processes.
2. How do natural fibers differ from synthetic fibers in terms of their properties?
Ans. Natural fibers tend to be breathable, biodegradable, and comfortable against the skin, making them ideal for clothing. For example, cotton is soft and absorbent, while wool provides warmth. In contrast, synthetic fibers are usually more durable, resistant to wrinkles, and can be water-resistant, but they may not be as breathable. However, they can be made to mimic the feel of natural fibers while offering additional benefits like stretch and durability.
3. What is the process of converting fibers into fabric?
Ans. The process of converting fibers into fabric involves several steps. First, the fibers are harvested and cleaned. Next, they undergo spinning, where they are twisted together to form yarn. After that, the yarn is woven or knitted to create fabric. Finally, the fabric may go through finishing processes such as dyeing, printing, or treating to enhance its appearance and performance before it is made into clothes.
4. Why is cotton considered a popular choice for clothing?
Ans. Cotton is considered a popular choice for clothing because it is soft, breathable, and absorbent, making it comfortable to wear in various climates. It is also easy to dye and can be produced in large quantities, which contributes to its affordability. Moreover, cotton is versatile and can be used to make a wide range of clothing items, from casual wear to formal attire.
5. What impact do synthetic fibers have on the environment?
Ans. Synthetic fibers can have a significant impact on the environment. They are often made from petroleum-based resources, which can contribute to pollution and depletion of natural resources. Additionally, when synthetic clothing is washed, microplastics can be released into water systems, harming aquatic life. On the other hand, some synthetic fibers are now being developed to be more sustainable, but their overall environmental impact remains a concern.
