FAQs on Fibre to Fabric Class 7 PPT

1. What is fibre?
Ans. Fibre refers to a thin thread-like structure that is obtained from natural or synthetic sources. It is the basic unit used to make fabrics and textiles.
2. How is fibre produced from cotton?
Ans. Cotton fibre is obtained from the cotton plant's seed. The process starts with harvesting the cotton bolls, followed by ginning to separate the cotton fibres from the seeds. These fibres are then cleaned, straightened, and spun into yarns, which are further used to make fabrics.
3. What are the different types of natural fibres?
Ans. Natural fibres can be classified into three categories: plant fibres (such as cotton, jute, and linen), animal fibres (like wool and silk), and mineral fibres (such as asbestos and mineral wool).
4. How are synthetic fibres different from natural fibres?
Ans. Synthetic fibres are man-made and produced through chemical processes. They are derived from petrochemicals or coal. In contrast, natural fibres are obtained directly from plants, animals, or minerals without any chemical processing.
5. What is the importance of fibre to fabric?
Ans. Fibre to fabric plays a crucial role in the textile industry. It involves the conversion of raw fibres into functional fabrics, which are used for making various clothing and textile products. Understanding the process of fibre to fabric helps in ensuring the quality and durability of the final products.
