A blanket is a type of bedding, generally speaking, a large piece of cloth, intended to keep the user warm, especially while sleeping. Blankets are distinguished from sheets by their thickness and purpose; the thickest sheet is still thinner than the lightest blanket, because blankets are for warmth, while sheets are for hygiene, comfort and aesthetics. Blankets are subdivided into many types, including quilts, duvets, and comforters, depending on their thickness, construction and/or fill material. Electric blankets are heated by electricity. Blankets were traditionally made of wool because of wool's warmth, breathability and natural fire-retardant properties, while sheets were made of cotton or linen, which are less irritating to the skin. These days, synthetic fibers are frequently used for both. Throw blankets are smaller blankets, often in decorative colors and patterns, that can be used for extra warmth outside of bed.
The term arose from the generalization of a specific fabric called Blanket fabric, a heavily napped woolen weave pioneered by Thomas Blanket (Blanquette), a Flemish weaver who lived in Bristol, England in the 14th century. Earlier usage of the term is possible through its derivation from the French word for white, blanc. 
Blankets may also be used on the ground for a picnic or other places where people want to sit in a grassy or muddy area without soiling their clothing. Temporary blankets have been designed for this purpose, although their inherent wastefulness is a chief concern of several environmental groups.
Specialized blankets known as fire blankets may be used by firefighters to protect furnishings from water damage during firefighting. Firefighters often wear specialized variants of the fire blanket to protect themselves as well.
Thick quilted and durable blankets are used as protective covers and cushioning when furnishings are moved.
A warming coat for a horse is called a horse blanket, intended to prevent the development of a shaggy winter coat of hair. A small saddle blanket protects the horse's skin from chafing by the pressure points of a saddle.
To keep warmth inside the body, a blanket can be used to cover one's skin and keep the warmth in. Many kinds of blankets, such as wool are used because they are thicker and have more substantial fabric to them, but cotton can also be used for light blankets. The term blanket is often interchanged with comforter, quilt, and duvet, as they all have similar uses.
The US Department of Defense uses wool blend blankets for disaster relief where warmth and comfort are desirable characteristics. The specifications for these blankets are outlined in the item description for National Stock Number (NSN) 7210-00-119-5335.
A blanket is a large, usually rectangular piece of cloth, generally used on a bed over a sheet to keep the sleeping person warm. Some blankets are knitted or crocheted while others are made of two layers of cloth sewn together with stuffing in the middle. Blankets can be made with hollow fibre or feathers.
Other names for blankets are quilts, duvets, and comforters, depending on their thickness, construction and/or stuffing.
Blankets may also be used on the ground for a picnic or other places where people want to sit without their clothing getting dirty or wet.
Electric blankets are heated by electricity. Blankets were traditionally made of wool because it is warm, naturally fire-retardant, and allows air to circulate well, while today synthetic fibers are frequently used. Throw blankets are smaller blankets, often in decorative colors and patterns, that can be used for extra warmth outside of bed.
Blanket terminology is also used in the printing industry. A blanket is a rubber coating over different layer of compressible material. It wraps around a cylinder and insures transfer of ink form the printed material (where the image is ink defined) to the paper. Blankets are used for Offset, gravure, flexo, etc.bjn:Gabang
