उत्तर
Chemistry is often used in the textile sector, which produces clothes for humans. Clothing protects our bodies from the outside world. Clothing formation begins with understanding how fibres are converted into fabrics. Fibres can be both natural and manufactured. In the past, man only knew natural fibres like cotton, jute, silk, and wool, which were used to make dress fabrics, sarees, purses, sweaters, shawls, and so on. As technology advanced, synthetic fibres, such as nylon and terylene, were created. These fibres are solid, wrinkle-resistant, and dried quickly. Towels, bed sheets, bags, curtains, carpets, blankets, and garment materials are among the products made from them.
