ETYM Old Eng. lether, as. lether; akin to Dutch leder, leęr, German leder, Old High Germ. ledar, Icel. lethr, Swed. läder, Dan. laeder.
An animal skin made smooth and flexible by removing the hair and tanning.
Material prepared from the hides and skins of animals, by tanning with vegetable tannins and chromium salts. Leather is a durable and water-resistant material, and is used for bags, shoes, clothing, and upholstery. There are three main stages in the process of converting animal skin into leather: cleaning, tanning, and dressing. Tanning is often a highly polluting process.
The skin, usually cattle hide, is dehydrated after removal to arrest decay. Soaking is necessary before tanning in order to replace the lost water with something that will bind the fibers together. The earliest practice, at least 7;,000 years old, was to pound grease into the skin. In about 400 bc the Egyptians began to use vegetable extracts containing tannic acid, a method adopted in medieval Europe. Chemical tanning using mineral salts was introduced in the late 19th century.
A natural protective covering of the body; site of the sense of touch | SYN: tegument, cutis. The covering of the body of a vertebrate. In mammals, the outer layer (epidermis) is dead and its cells are constantly being rubbed away and replaced from below; it helps to protect the body from infection and to prevent dehydration. The lower layer (dermis) contains blood vessels, nerves, hair roots, and sweat and sebaceous glands, and is supported by a network of fibrous and elastic cells. Skin grafting is the repair of injured skin by placing pieces of skin, taken from elsewhere on the body, over the injured area. The medical specialty concerned with skin diseases is called dermatology.
