Twill is the second most basic weave after plain weave. The filling threads are woven over and under two or more warp yarns, which produces a characteristic diagonal pattern. These (face side) lines are called wales. The fewer interlacings in twill allow the yarns a greater range of motion and thus can move more freely. usually is softer, more pliable, and drape better than plain-weave textiles. Alternatively, because fewer crossings, the yarns can be set closer together, producing a higher thread count fabric that is heavier and therefore can be more durable and resistant to wind and water. The angle of the twill can also distinguish the sturdiness of the fabric - the steeper the angle, the more warp yarns were employed (45˚ is common) Soils and stains are less noticeable on twill than on other fabrics. Twill also recovers wrinkles better then plain weaves do. Some twill weaves will be sanded or brushed as a final step to remove and smooth out the distinction of the ribs. Brushing produces a smooth finish, but has a slightly fluffy characteristic. A sanded finish is also smooth, but since the sanding shortens the hairs, it ends up having somewhat of a suede feel to it. A common example of a twill weave is denim and in used in blue jeans.
