Summary
Texturing is increasingly important in textile production, not only in yarns for weaving and knitting fashion products, but also for carpets, furnishing fabrics and a variety of technical textiles. Yarn Texturing Technology covers all the major techniques including twist-texturing, jet-screen texturing, false-twist process, BCF processes and air-jet texturing in detail.
Combining a comprehensive review of the physics and chemistry of texturing with a thorough, illustrated description of current practice, this book will be invaluable for yarn and fabric manufacturers, textile scientists and students in textile science and technology courses.
