Book Description
Excerpt from Action of Sodium Sulphate in Synthetic Tanning Materials It therefore follows that if a hide is treated with a solution contain ing both sodium sulphate and a synthetic tanning material (which is usually an active acid) both the sulphuric acid and the tanning material will combine with the hide to a certain extent. In other words, the neutralization of the excess sulphuric acid ln syntans, by means of sodium hydroxide or any other reagent 'which yields a soluble sulphate, does not entirely prevent the sulphuric acid from reacting with the hide during the tanning process. The extent to which the sulphuric acid and the synthetic tanning agent will combine with the hide under these conditions is not yet definitely known, but it is probable that an equilibrium will ultimately be reached, depending partly on the nature of the syntan and partly on the concentrations of the reagents in the tanning solution. But whatever the amount of the sulphuric acid which will be combined ln the leather, the results obtained in the present study indicate that this can not be com pletely removed by any amount of washing with water at ordinary temperatures. It is possible and even probable that this combined sulphuric acid which remains in the leather after thorough washing will have no injurious effect on it, but this still remains to be definitely ascertained. In any case, thorough washing of the leather after using a syntan which contains any considerable amount of sodium sulphate or other soluble sulphate is always necessary in order to prevent injury from the free sulphuric acid which would result from the inter action of the sulphate with any excess of uncombined sulphonic acid.

Book Description
Even in the 21st Century, the manufacture of leather retains an air of the dark arts, still somewhat shrouded in the mysteries of a millennia old, craft based industry. Despite the best efforts of a few scientists over the last century or so, much of the understanding of the principles of tanning is still based on received wisdom and experience. Leather is made from (usually) the hides and skins of animals - large animals such as cattle have hides, small animals such as sheep have skins. The skin of any animal is largely composed of the protein collagen, so it is the chemistry of this fibrous protein and the properties it confers to the skin with which the tanner is most concerned. In addition, other components of the skin impact on processing, impact on the chemistry of the material and impact on the properties of the product, leather. Therefore, it is useful to understand the relationships between skin structure at the molecular and macro levels, the changes imposed by modifying the chemistry of the material and the eventual properties of the leather. This book aims to contribute to changing the thinking in the industry, to continue building a body of scientific understanding, aimed at enhancing the sustainability of an industry which produces a unique group of materials, derived from a natural source. The Science of Leather is the only current text on tanning science, and addresses the scientific principles which underpin the processes involved in making leather. It is concerned with the chemical modification of collagen, prior to tanning and the tanning reactions in particular. The subject is covered in the following order: collagen chemistry, collagen structure, skin structure, processing to prepare for tanning, the tanning processes and processing after tanning. The aim of the book is to provide leather scientists and technologists with an understanding of how the reactions work, the nature of their outcomes and how the processes can be controlled and changed. The objective is to synthesise a scientific view of leather making and to arrive at an understanding of the nature of tanning - how the wide range of chemistries employed in the art can change the properties of collagen, making leather with different properties, especially conferring different degrees of stabilisation as measured by the hydrothermal stability. Environmental issues are not treated as a separate theme - the impact of leather making on the environment is a thread running through the text, with the assumption that better understanding of the science of leather making will lead to improved processing. The book also reflects on the ways leather technology may develop in the future based on the foundation of understanding the scientific principles which can be exploited. It also includes a subject index, references and a glossary. The book provides the reader with insights into the role science plays in leather technology and provides fundamental understanding, which should be the basis for scientific and technological research and development for the benefit of the global leather industry. The book is aimed at students, leather scientists and technologists, in both academia and industry, in leather production and in chemical supply houses.
