Fabrics serve several important roles in interior design. They protect furnishings from fading and deterioration caused by sunlight. Fabrics also provide privacy, reduce glare, and can help rooms feel cooler. For interior fabrics, properties like light fastness, stain resistance, and flame retardancy are important. Common interior fabric applications include upholstery, curtains, blinds, bedding, wall coverings, bathroom linens, and tablecloths. New fabric treatments provide benefits like stain and water repellency while remaining breathable and eco-friendly.
