Essential Reading Materials
To supplement the video lectures and assignments, the following textbooks are highly recommended:
- Yarn Texturing Technology by D. K. Wilson, J. W. S. Hearle, and L. Hollick
- False Twist Textured Yarns: Principles, Processes and Applications by C. Atkinson
Industry Relevance & Applications
Textured yarns are ubiquitous. They are the foundation of:
- Stretch fabrics in sportswear, swimwear, and intimate apparel (from false-twist yarns).
- Soft, bulky sweaters and winter wear (from hi-bulk yarns).
- Durable upholstery, carpets, and seat covers (from BCF yarns).
- Simulated natural yarns for outerwear and home textiles (from air-jet textured yarns).
This course demystifies the technology behind these everyday materials, making it invaluable for anyone involved in the textile value chain, from fibre production to fabric design and manufacturing.
Enroll today to unravel the fascinating technology of textured yarns and advance your expertise in the dynamic field of textile engineering.
