Hauteur is
mean fibre length in a top
. Hauteur is usually regarded as a numerical average (i.e.. Assumes no relationship between fibre length and diameter), but is actually a length-biased distribution. The variation in the length is expressed as CVH%.
What does NKT mean in wool?
Staple strength is a measure of the force is required to break a wool staple of a given thickness (kilotex), recorded as
Newtons per kilotex
(Nkt).
What is an almeter?
The Almeter – This is the
measuring instrument which scans the fibre beard between
.
2 electrodes and measures the electrical resistance between them
; the capacitance.
What is staple strength?
Staple strength is
calculated as the force required to break per unit staple thickness
, expressed as newtons per kilotex. The staple strength of wool is one of the major determining factors of the sale price of greasy wool.
How do you measure staples for wool?
Generally measuring starts
at the shorn end
– the part closest to the animal – following the fiber to the tip as shown in the picture. As you can see above the darkest wool on the left side of the ruler measures in at about 7 inches.

What determines wool value?
The price of wool varies according to many wool characteristics: the category,
fibre diameter (micron), length, strength, amount of vegetable matter
are some prime price variables. See Figures 3a & 3b. In simple terms fleece wool can vary between 12 and 45 micron. The finer the micron the higher the price.
What is staple yarn?
Staple yarns, also called spun yarns, are
made of fibers that come in short discrete lengths
. All natural fibers except silk are staple fibers. … Silk is such a fiber, and manufactured fibers are produced in filament form. The manufactured filaments can then be cut into staple lengths if staple yarns are desired.
Is wool staple or filament?
Filament
fibers are continuous (long) fiber. Any fiber with a practical, limited or finite length is called staple fiber. These are small length fibers like cotton, wool, jute etc.
Is wool a staple Fibre?
Staple fibres are usually
natural fibres
, although synthetic fibres can be cut into similarly short lengths to be blended with natural staple fibres or used on their own to produce yarns with a natural feel. Natural staple fibres include cotton, wool and flax.
What is Grade A wool?
A 64s wool yields 35,840 yards (560 times 64) of yarn from 1 pound of 64s top. The micron system most accurately measures the average diameter of the wool fiber. The micron (1/25,400 inch) is the actual average diameter measurement. … A wool grader classifies the whole fleece according to its grade (
fineness
) and length.
What micron is fine wool?
Fine wool has a fibre diameter of
18.6-19.5 microns
. Fine-Medium wool is in the micron range 19.6-20.5.
What is a good wool micron?
A micron is the measurement of the diameter of a wool fibre.
A lower micron number means a finer fibre. Merino wool is the finest and usually measures anything from
15 to 25 microns
but can still be finer. Other wool varies in micron and this depends on the breed of the sheep, the health and age of the sheep.
What are the disadvantages of wool?
DISADVANTAGES:
It can be scratchy and uncomfortable to wear, and heat and moisture can cause it to felt
. Soak wool in cold water, and then gently rub out anywhere that needs extra cleaning. You can wash it in the washing machine, but use cold water, and air dry it.

- Odour resistant. In contrast to synthetics, Merino wool can absorb moisture vapour which means less sweat on your body. …
- Soft on skin.
