Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Surfactants Applications Directory written by D.R. Karsa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing surfactants directories tend to focus on product identification by tradename, producer or chemical type, enabling the user only to identify product equivalents and surfactant suppliers. Application information, where available, is usually scant or given as a footnote. This new directory approaches the identification of surfactants primarily from the applications standpoint. Hence the formulator or end-user can readily assess the products available for use in a particular industry sector and select materials giving the required surface active properties. For example, a formulator of agrochemicals for crop protection can turn to the section which refers to surfactants for use in the agrochemical industry and then easily identify a wetter/dispersant system for the production of water dispersible granules. Information is presented in an alternative format in the second part of the directory, which will help the user to identify swiftly products for a particular application by surface active properties. It is difficult, if not impossible, to identify an industry which does not directly or indirectly utilise surfactants. Therefore it has proved necessary to simplify industry classifications to encompass a variety of uses under broader sector titles. The industry classifications adopted here have been used in many previous publications and papers, and define as accurately as possible the major industries and applications serviced by the surfactant industry. The editors have been particularly pleased with the support and response of the industry in the supply of data.
Download or read book Science for Students of Leather Technology written by R. Reed and published by Elsevier. This book was released on 2016-05-03 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science for Students of Leather Technology is the first of a series of textbooks of leather science and technology designed to assist students at technical colleges and institutes as well as at universities. The book begins with an introduction to leather manufacturing. This is followed by separate chapters on the physical chemistry of solutions needed by students of leather manufacture; types of macromolecules; lipids and their use at various stages of leather manufacture; and the principles of their use as surface agents. Subsequent chapters deal with the general features of skin as an organ; how the skins from different animals may develop their special characteristics; common problems arising from insects and from micro-organisms in leather manufacture; and the structure and reactions of chromium complexes, which are the most widely used tanning agents; and modern views on the structure of the vegetable tannins and of the dyestuffs and pigments. This book is intended for students with a variety of backgrounds. Those whose chemical studies have not proceeded much beyond the elementary level will find considerable difficulty with some sections, especially where the organic chemistry of complex molecules (proteins, carbohydrates, dyes and vegetable tannins) is described. It is, however, possible to supplement the explanations given by reference to standard chemical textbooks, using the subject matter of the present volume as a guide to those sections which would repay further study.

This book was released on 2023-05-08 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores how bioremediation biotechnology is used to remove pollutants in wastewater. Remediation of wastewater is important to ensure that pollutants generated in industry do not effect our environment negatively. Traditional wastewater remediation is not a sustainable process, however by using biological means the sustainability can be improved. Both conventional methods and bioremediation technologies are discussed. Applications for heavy metal, nitrate, and petroleum bioremediation, nanotechnology in bioremediation, and more are explored.
