This book contains detailed knowledge about testing principles of fibre, yarn, and fabric characteristics, the tensile characteristics of materials and testing of fibrous-composites and technical textiles. It starts with an introduction to textile testing and further covers moisture in relation to textile materials, sampling techniques for textile materials and the basic applied statistics, fibre characteristics, fibre length, cotton fibre fineness and maturity characteristics. It also deals with the advanced characterisation of cotton fibre by using HVI and AFIS systems.
Features:
- It covers the principles of the testing of textile and fibrous materials along with modern techniques for testing textile materials
- It reviews all necessary topics related to fibre, yarn, fabric, technical textiles, and composite testing
- It explores the tensile characteristics of textile materials and measurement principles
- It discusses low-stress mechanical characteristics and transmission characteristics
- It includes a large number of examples and exercises based on actual industrial conditions worldwide including solutions
This textbook is aimed at senior undergraduate students in textile testing and evaluation of textile materials.
