Carpets are categorized by their construction, patterns, and yarns. They enhance the appearance of homes and workplaces, and provide noise absorption and comfort. Carpets are constructed through weaving, tufting, or bonding methods. Woven carpets like Wilton, Axminster, and oriental are durable but costly, while non-woven tufted and bonded carpets are more economical options. Carpets are made from synthetic materials like nylon and polyester for the pile and polypropylene for the backing. They are chosen for qualities like appearance, sound absorption, and comfort.
