The blanket is a large soft cloth. This item is usually used to keep warm while sleeping or lying down. Blankets capture the radiant heat of the user's body; instead of dissipating in the air, they warm the user. It can also prevent heat loss during convection.

Many types of blanket materials (such as wool) are used because they are thicker and have stronger fabrics, but cotton can also be used as a light blanket. Compared with cotton, wool blankets are warmer and burn more slowly. The most common types of blankets are woven acrylic, knitted polyester, marten, cotton, wool and wool. Blankets also carry exotic handicrafts and exotic materials, such as Crocheted Afghan or silk coverings. The word blanket is often interchanged with quilt, quilt and duvet because they all have similar uses.
