Flannel is a soft woven fabric, of various fineness. Flannel was originally made from carded wool or worsted yarn, but is now often made from either wool, cotton, or synthetic fiber. A textile made from Scots pine fibre is called vegetable flannel. Flannel may be brushed to create extra softness or remain unbrushed. Brushing is a mechanical process wherein a fine metal brush rubs the fabric to raise fine fibres from the loosely spun yarns. Typically, flannel has either a single- or double-sided nap. Double-napped flannel refers to a fabric that has been brushed on both sides. If the flannel is not napped, it gains its softness through the loosely spun yarn in its woven form. Flannel is commonly used to make tartan clothing, blankets, bed sheets, and sleepwear.
