Unique characteristic of natural wool fiber : Wool is the natural hair on sheep and is composed of natural protein called keratin. It contains carbon, nitrogen and is the only animal fiber contains sulphur.
Wool fiber contains crimps and curls which give the spongy feel and also create the insulation of wearer.
Properties of wool fiber- physical and chemical
It is the protein fiber
Sheep wool has the capability to keep the body at even temperature because it does not trap heat, it insulates instead. This means that in hot weather it keeps us cool and in cold weather it keeps us warm.
It is naturally fire resistant
Sheep wool is more strong and durable
Ability to felt
It regains moisture 25%
It elongates 25-40%
It is easily affected by micro organism and insects
Luster of course fiber is higher than fine fiber
Characteristic of wool
Tendency to deformation
Tendency to shrink
Good moisture absorbency
Good dyeing fastness
Sensitive to the sun
End use of wool
Technical textile: felting
Home furnishing : carpets , blankets , upholstery and draperies.
Absorbency creates comfort
When wool absorbs water or moisture from air it produce heat. if you go inside the cool room , the wool absorbs moisture from the air and makes you warm.. The opposite reaction takes place when you go into the warm place ; the moisture from the room is released into the air and makes you cool.
These are the natural properties of wool fiber.. if we go deep lot of technical things about this fiber can be knowm
Flexibility : The interior structure creates
The cortical cells have complex structure. The component within this cell is spring like structure . so it is flexible and elasticity is high .
Additionally it has wrinkle resistance properties.
