2
Wool fibres generally have a matte appearance so are not typically lustrous. They are often blended with other fibres such as silk to increase lustre. LUSTRE
3
Drape The drape of wool is exceptional, making it perfect for all types of apparel and furnishings.
4
Abrasion Resistance The durability of wool is good. Abrasion resistance is moderate. This is due to the fibre's scale construction and excellent elasticity.
5
Strength Wool fibres are weak, due to the fibre's highly amorphous structure. The coarser the wool diameter, the stronger the wool fibre
6
Absorbency Wool is extremely absorbent and is therefore comfortable in most conditions. The absorbency is high due to the fibres amorphous regions
7
Elongation The elongation of wool is excellent. When stress is placed on the fibres they elongate and when the pressure is removed the natural coils spring back into their original position.
8
Thermal Properties Wool is considered to be a poor conductor of heat, so is known as a warm fibre. It possesses excellent insulation properties. Wool does not burn; it has a self extinguishing property that makes it perfect for flame resistant cloth
9
Resiliency Wool is a very resilient fibre; it resists wrinkling. Its ability to bounce back into shape makes it an ideal fibre to use for rugs and carpeting
10
Dimensional Stability Wool has poor dimensional stability
11
Elasticity Wool has excellent elastic recovery.
12
Effects of Chemicals Wool does not soil readily. Wool is resistant to acids but is weakened by alkalis and is damaged by chlorine bleach.
13
Sun Resistance The sun yellows wool over time and weakens the fibre.
14
Colour Fastness Colour fastness in dyed wool is excellent, and wool is dyed readily due to its highly amorphous structure.
15
Shrink Resistance Wool has poor shrink resistance. This property, combined with the scale structure of the wool fibre, create the fibre's ability to form felt.
16
Resistance to biological attack Wool is not resistant to biological attack. In fact it is the perfect food source for moth larvae, which hatch and damage wool by feeding on the fibres.
