Studies on The Manufacturing Procedure of Book Binding Leather

The decayed leather binding with a flaking or powdery surface and a broken spine is an all too common sight in many book collections. Bindings in this condition will remain a perpetual and ever increasing problem unless binders ensure the leather they use has a long term resistance to acidic atmospheric pollutants. Binders tend to select leather on aesthetic appearance and the way the leather handles during the binding operations. Insufficient consideration is given to the durability of the leather, but unfortunately there is little to guide the purchaser with regard to this property.

However the last eight years have seen the development of a combination tannage involving both vegetable tannins and aluminum salts that confers on the binding leather a markedly increased resistance to atmospheric pollutants. Such archival quality leathers with this semi-aluminum tannage are now being produced commercially and this paper describes the rigorous testing to which such leathers have been subjected in order to demonstrate their superior durability.

Book-binding leather are more softy usually full vegetable tanned leathers made from goat, sheep and calf skins. Book-binding leather should be-

• Book-binding leather must have very good tensile strength.
• Book-binding leather must have resistance to perspiration fastness.
• The grain finished leathers should be well let out to give a smooth grain surface.
• The grain-break should be free from looseness and pipyness.
• Book-binding have water -proof.
• Book-binding have by lasting 100-150 years.
• Book-binding leather have good tearing strength.
• Aesthetic feel.
• Used dye should not be pH sensitive.
• Light fastness not less than rating 4 on the blue wool scale.
• The fat content should not be less than 4% of the leather weight.

We are living new millenniums. Technology is growing rich every day. People demand is increasing. Many competitors are waiting in market to fulfill their demands. If we want to survive in this competition we have to acquire modern technology. Technology never now without successful experiment.

It is a fact that we are accustomed to use leather goods in our life to a large extent. Further more using leather goods are also a matter of status and prestige in many countries. As observed, it is easy to make book binding with leather but difficult to maintain it’s quality. For this reason, I took low graded goat skin and turned it to quality book binding leather. All the way of my project work I always give a though of quality and production cost.

Foreign currency can be gained in a significant way which may develop the country economy as raw materials and labor are two most important factor but available in our country.
