Since cotton fibers are fairly inelastic, cotton fabrics may wrinkle easily. And, fabric may need frequent pressing. The label will tell you if this finish has been applied. A higher heat setting is needed in the dryer to dry cotton. Cotton will take much longer to dry than less absorbent fibers.
Some linens are washable, while others are dry clean only.
Be sure to check the label. Washable household linens, handkerchiefs, and linen apparel can be washed easily and become softer with use. White linens should be dried in the sun, if possible, to help them to keep their whiteness. Generally speaking, dry cleaning is recommended for drapery linens, upholstery linens and decorative linens. Linen fabrics may need frequent pressing, unless treated for crease resistance.
