2. List the factors which determine the quality
of wool fibre.

grabbing other fibres?
4. Why is wool most suitable for winter wears?
5. What is th
Answers
Answer:
2. Many factors determine the quality (and value) of wool. These include fiber diameter, crimp, yield, color, purity, and staple length and strength. Fiber diameter, also called fineness, is the actual measurement of the thickness of the wool fiber.
3. The crimp in wool fibres makes it soft and springy to touch. It also adds bulk and traps a large volume of air between the fibres, giving it good insulation properties. Finer fibres with more crimp such as Merino create fabrics that drape better than coarser fibres.
4. Wool can easily absorb up to 30% of its weight in moisture without feeling wet or sticky. Wool fabrics have built-in climate control. Wool is a natural insulator. Hence, it can keep the body warm in winter and cool in summer as it's breathable.

Answer:
2) Many factors determine the quality (and value) of wool. These includes fibre diameter , crimp , yield , colour , purity and staple length and strength. Fibre diameter also called fineness , is the actual measurement of the thickness of the wool fibre.
3) The crimp in wool fibres makes it soft and springy to touch. It also adds bulk and traps a large volume of air between the fibres, giving it good insulation properties. Finers fibre with more crimp such as Merino creates fabrics that drape better than coarser fibres.
4) The structure of the wool fibre causes thousands of tiny air pockets to form in wool fibre. In cold weather these trap body heat like a thick blanket does. However, those same air pockets mean that air can flow through the fabric allowing the body to cool itself through the evaporation of sweat.
