Leather

  1. 1. LEATHER : TYPES AND USES Presented by – Sakshi Singh BFAD II yr
  2. 2. LEATHER •Leather is a durable and flexible material created by the tanning of animal rawhide and skin, often cattle hide. •It can be produced through manufacturing processes ranging from cottage industry to heavy industry. •Leather is used for various purposes including clothing (e.g. shoes, hats, jackets, skirts, trousers and belts), bookbinding, leather wallpaper, and as a furniture covering.
  3. 3. Processes Several tanning processes transform hides and skins into leather: • Vegetable-tanned leather is tanned using tannins and other ingredients found in different vegetable matter, such as tree bark prepared in bark mills, wood, leaves, fruits and roots and other similar sources. • Chrome-tanned leather, invented in 1858, is tanned using chromium sulphate and other salts of chromium. • Aldehyde -tanned leather is tanned using glutaraldehyde or oxazolidine compounds.
  4. 4. • Brain tanned leathers are made by a labor -intensive process which uses emulsified oils, often those of animal brains such as deers , cows , and buffaloes. • Chamois leather also falls into the category of aldehyde tanning and, like brain tanning, produces a porous and highly water-absorbent leather. • Rose tanned leather is a variation of vegetable oil tanning and brain tanning, where pure rose otto replaces the vegetable oil and emulsified oils.
  5. 5. • Synthetic-tanned leather is tanned using aromatic polymers such as the Novolac or Neradol types (syntans, contraction for synthetic tannins). • Alum-tanned leather is transformed using aluminium salts mixed with a variety of binders and protein sources, such as flour and egg yolk. • Rawhide is made by scraping the skin thin, soaking it in lime, and then stretching it while it dries.
  6. 6. Types • Full-grain leather refers to hides that have not been sanded, buffed, or snuffed (as opposed to top-grain or corrected leather) to remove imperfections (or natural marks) on the surface of the hide. The grain remains allowing the fiber strength and durability. The grain also has breathability, resulting in less moisture from prolonged contact. Rather than wearing out, it will develop a patina during its expected useful lifetime. High quality leather furniture and footwear are often made from full-grain leather. Full-grain leathers are typically available in two finish types: aniline, semi- aniline.
  7. 7. • Top-grain leather (the most common type used in high-end leather products) is the second-highest quality. It has had the "split" layer separated away, making it thinner and more pliable than full-grain. Its surface has been sanded and a finish coat added to the surface which results in a colder, plastic feel with less breathability, and it will not develop a natural patina. It is typically less expensive and has greater resistance to stains than full-grain leather, so long as the finish remains unbroken.
  8. 8. • Corrected-grain leather is any leather that has had an artificial grain applied to its surface. The hides used to create corrected leather do not meet the standards for use in creating vegetal- tanned or aniline leather. The imperfections are corrected or sanded off, and an artificial grain embossed into the surface and dressed with stain or dyes. Most corrected-grain leather is used to make pigmented leather as the solid pigment helps hide the corrections or imperfections. Corrected grain leathers can mainly be bought as two finish types: semi-aniline and pigmented.
  9. 9. • Split leather is leather created from the fibrous part of the hide left once the top-grain of the rawhide has been separated from the hide. • Splits are also used to create suede. • The strongest suede's are usually made from grain splits (that have the grain completely removed) or from the flesh split that has been shaved to the correct thickness. • Suede is "fuzzy" on both sides.
  10. 10. USES OF LEATHER • Leather is used for many proposes especially in the fashion business because of its interesting qualities; it can be made into shoes, bags, hats, items of clothing like coats, jackets and several other important ready made goods. • The industrial application and commercial value of leather industry is enormous considering the varied uses of leather such as for automobile seats, home appliances used for chair covers, tables, motorcycle seats and many more value added items.
