CHANDRASEKHARA Introduction This book highlights bamboo fibre extraction, properties and applications. It is a comprehensive collection of detailed chapters ranging from bamboo fibre history, its growth characteristics to its applications and techno- economics. The book provides an overview of bamboo fibre extraction and its processing. The book commences with a chapter on introduction to bamboo fibres and the history of bamboo, growth characteristics of bamboo such as types of bamboo and morphology of bamboo are dis- cussed in detail. This is followed by chapters providing comprehensive information on bamboo fibre extraction; its characterization and its physi- cal, comfort, thermal and low-stress properties as well as detailing the pro- duction of yarns and fabrics. The book concludes with chapters on the antimicrobial properties of bamboo fibres, chemical processing of bamboo fibres, yarns and fabrics and the application and techno-economics of bamboo fibre production and processing aspects. Bamboo Fibres: Processing, Properties, and Applications is an essential book for all those concerned with bamboo fibre extraction, its processing aspects and properties, its produc- tion and extension, its research and development and its application in textile and other industries. It will serve as a valuable material for textile and fashion industry professionals, research scientists, and academia. It is a comprehensive resource material for students and academicians. xv Foreword Nowadays, when pollution by synthetic microfibres is one of the biggest plastic pollution issues, we are returning to biodegradable, natural fibres to save our environment. The family of fibrous cellulosic raw materials, such as cotton, jute, flax, hemp, kenaf, sisal, ramie, coir and bamboo, and recently discovered many other lignocellulosic natural fibrous resources can be extracted, processed, modified, specially functionalized and applied in the production of the textiles: woven, knitted, nonwoven, technical, 3D textiles and also used as reinforcement of more friendly composites. Now the future of natural fibrous resources, new trends in their pro- duction, processing, wider application and their competition with man- made fibres in the 21st century is very important for decreasing pollution and CO emissions. 2 Bamboo has a short reproduction time, grows with solar energy and water, extracts CO from air and releases oxygen. It is a lignocellulosic 2 plant that grows very fast, with high structural organization and with many advantages. It helps millions of global people to live. At the end of 20th century, on the base of bamboo biomass, bamboo fibre was developed as a textile fibre, similar to viscose and cotton. In the book, “Bamboo Fibres: Processing, Properties and Applications,” the authors have compiled the current knowledge including an introduction and history of bamboo fibres; the growth characteristics of bamboo: types of bamboo, morphology of bamboo; the extraction methods for bamboo fibres—various extraction methods, different types of bamboo fibres; the characterization of bamboo fibres: physical and chemical composition, characterization of bamboo using X-ray, IR and other techniques; the properties of bamboo fibres—physical, performance, comfort thermal and low stress mechanical properties; the production and properties of bamboo yarns and fabrics; the investigation and comparison of antibacterial prop- erty of bamboo plants, natural bamboo fibres and commercial bamboo viscose textiles; the chemical processing of bamboo and bamboo products and the applications and techno-economics of bamboo fibres. xiii xiv Foreword This book provides comprehensive knowledge about these new emerging fibres, and the target readers may be scientists, students, indus- trial people, policy makers and consumers.
