Synthetic Fibres

The video tutorial explores various types of fabrics, focusing on the distinction between natural and synthetic fibers. It explains how synthetic fibers like rayon, nylon, polyester, and acrylic are produced and their unique properties. Rayon, known as artificial silk, is derived from wood pulp and undergoes chemical processing. Nylon, a fully synthetic fiber, is noted for its strength and versatility. Polyester, formed from esters, is used in clothing and other products, while acrylic is popular for warm clothing. The video also highlights the safety concerns of synthetic fibers near fire.
