Dr. Menghe Miao is a Fibre and Textile Technology Consultant, having retired from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) as a Principal Research Scientist in materials science and engineering in 2022. He was an Honorary Professorial Fellow in the Department of Mechanical Engineering at The University of Melbourne during 2019-2023. Before joining CSIRO, he was a Research Leader at the Wool Research Organisation of New Zealand (WRONZ) and taught and conducted research on yarn spinning technology at China Textile University and The Hong Kong Polytechnic University, after receiving his PhD from The University of Leeds in 1985.

Dr. Miao's research and publications cover various aspects of the science and engineering of fibre-based materials, including textile manufacturing technology, product engineering, fibre-reinforced composite materials, the production and properties of carbon fibres and carbon nanotube yarns, and textile-structured sensors, actuators, and energy storage devices. He has published over 200 refereed journal papers and research reports for the textile and related industries, as well as two edited books: Engineering of High-Performance Textiles and Carbon Nanotube Fibres and Yarns. Dr. Miao established the fundamental equations of yarn twisting dynamics, which form the basis of this book.

Klappentext

Yarn Twisting Dynamics presents the general differential equations of yarn twisting dynamics, describing rotational kinematics and kinetics, along with the twist blocking mechanisms of traveling yarns in straight and spatial paths. General solutions to yarn twisting dynamic equations, including twist wave propagation and twist distributions in idealized systems are also presented. Yarn tensile, torsional, and compressional properties are discussed based on yarn helical structure models. Users will find this book to be a first principles approach to yarn twisting problems in yarn manufacturing and handling systems.

Other sections cover yarn twisting dynamics and twist blockage theories, including conventional ring spinning, modified ring spinning, additive spinning (i.e., open-end spinning), constant and periodic false-twisting, rub-condensing (i.e., roving and slubbing production), false twist texturing, and carbon nanotube yarn production systems.
