Textile Chemistry Reference from C.H.I.P.S.

of Spun Yarn Technology

by Carl A. Lawrence

  • Covers the requirements of a first degree course in textile engineering or textile technology
  • Takes the subject beyond the first degree level to cover Masters level issues
  • Concentrates on the processing of the more commercially used natural and synthetic fibres
  • Explains the factors that govern the concept of yarn quality
  • Describes the principal routes of material preparation and various spinning techniques
  • Presents chapters of interest to students undertaking research in yarn technology
  • Contains more than 300 illustrations, including a full-color insert

Fundamentals of Spun Yarn Technology presents complete coverage of yarn manufacture and technology and current research findings on the structure and properties of spun yarns. Written by a well-known and respected authority on textile technology, it not only introduces the subject, but it provides students with an advanced understanding of the various process stages.

The book introduces the rudiments of staple yarn technology, covering the manufacturing process, the raw materials, and processes including short staple, worsted, semiworsted and woollen spinning, doubling, and specialty yarn processes. It also covers the more advanced studies in staple yarn technology, including new developments in fiber preparation technology, carding technology, roller drafting, gilling, ring spinning, open-end rotor spinning, air jet spinning and new research on unconventional spinning systems.

This extensive range of topics, along with hundreds of tables and illustrations presented in Fundamentals of Spun Yarn Technology make it a comprehensive and up-to-date treatment of the field.
