Mohair is almost non-inflammable. When exposed to a naked flame it burns at a low temperature and tends to shrink, the flame burning with a bead like ash.
It will stop burning almost as soon as it is taken away from the flame.
Due to its non-solid structure mohair can be bent and twisted without damage to the fiber.
This property helps its claim to be the most durable animal fiber.
Mohair is very elastic; the average fibre will go back to its original size and shape.
Because of this reliance mohair garments resist wrinkling, stretching and sagging during wear.
All animal fibers possess the ability to absorb moisture from the atmosphere readily.
Mohair dries slowly reducing the possibility of a chill.
Mohair may be set to retain extension or deformations more readily than other animal fibers, an this is greatly used in the manufacture of curled pile rugs or imitation astrakhan rugs.
It is this property which commends its use for furnishing fabrics and hangings, because the dust does not come to rest on its slippery fibers.
When any dust remains on the intersections of woven fabrics it can easily be removed by shaking or brushing.
Woven fabrics of mohair show scarcely any felting shrinkage and knitted mohair fabrics shrink much less than untreated wool.
Mohair is a relatively heavy fiber by itself but when blended with wool it makes up into a smooth material that can be made into fabrics
which are noted for coolness such as lightweight summer fabrics and is surpassed in tropic suitings.
For lining it is admirable because it combines coolness with durability.
The factors affecting the value of mohair may be considered in two related areas:
- The physical characteristics of the fibre:
- Freedom from kemp
(b) The impurities contained in the fibre which are in turn greatly influenced by the environment under which the animals are farmed.
