Wool differences between breeds - VIDEO: The key difference between wool from different sheep breeds is the diameter and the amount of crimp. Merino sheep produce very fine wool with a tight crimp – this makes it suitable for making into high-quality apparel. Coarser diameter wool such as crossbred has a long crimp and is used mainly for heavy apparel and carpets.
Exploring wool fibre properties - STUDENT ACTIVITY: In this activity, students explore the microstructure of wool fibre and how it relates to the properties and uses of wool. Purpose This activity will help students understand how the microstructure of wool creates its properties and determines its suitability for particular products.
