BOOK REVIEWS

focusing on sophisticated polymer functionalization and/or derivatization research should be aware of these Beilsteins of the functional groups, but not even they will be able to take out time and read these tomes cover-to-cover. Unfortunately, unlike in the Beilstein, the finding of specifics will not always be easy with the help of the rather inadequate (about 20 pages) Subject Index. Better guidance will be provided by the table of contents at the head of the chapters. However, even then, the searcher must know what he is looking for and must have experience of how to look for specifics in the maze of the individual and individualistic chapters. These books will be deposited in better-than-average libraries, but will not be part of the more modest collections of individuals.

Fibre Failure and Wear of Materials, J. W. S. Hearle, B. Lomas, W. D. Cooke, and I. J. Duerden, Halsted Press, New York, 1989,454 pp. Price: $160.00. The book “Fibre Failure and Wear of Materials” is a valuable contribution to the field of Fiber Science and Technology. The book offers an important and exhaustive overview of both single fiber failure and wear and breakdown of fiber products based on twenty years of work by the authors at UMIST. Although classification of failure is a difficult task, the authors have tackled the problem in a logical way. The book begins with an excellent overview of single fiber failure including tensile failure, fatigue and other kinds of failure of natural as well as man-made fibers. These chapters are followed by five others on different aspects of fiber failure in materials related to industry and consumer. These chapters deal with the case studies of materials including domestic and industrial fabrics followed by fiber archeology and textile conservation, which are looked at superficially. In the final chapter a summary of the text is presented with classification of breaks and some remarks on the diversity of forms of break. Though SEM provides only qualitative understanding of fiber failure, the authors demonstrate the importance of this tool very successfully. The book is extensively illustrated and is the first of its kind in the field. This book is highly recommended for textile technologists, polymer, and fiber scientists. S.

Injection Mould Design, R. G. W. Pye, Longman Scientific 8z Technical ( Wiley), New York, 1989,754 pp. Price $87.95. In “Injection Mould Design,” R. G. W. Pye displays a very good basic understanding of injection mold design. The 3-dimensional drawings are of great help to the newcomer. Sprues and runners are oversized according to todays standards and the hot runner designs (p. 489) are a little outdated. Some cooling designs (p. 707) will not give optimum results.
