Handling Raw Fleece
and Fleece Fiber Character |
|
|
This photo illustrates the condition of the fleece
after taken
from the
animal. This particular fleece measures more than 7 feet
long when
fully extended. Although we
have designated the color
of this fleece
as Fawn, you can see
that it displays a range of
natural hues from
grey to brown.

Although we skirt our fleeces, some
organic matter will
remain. This
material, usually hay or straw, may be
physically
removed with little
effort. Fleeces are sold in the grease
and have
not been washed. Each
is placed in a paper feed bag, this is then
stapled closed and placed
inside a plastic trash bag which is tied
shut. Because raw fleeces are
heavy with lanolin they may
appear dense when removed from their
packaging. Don't worry
that they appear to have lost the loft and
lightness of a freshly
recovered fleece. All of our fleeces are
guaranteed to spin like-a-
dream once carefully washed, carded, or
combed.

Below
is a table used to classify wool fibers by fiber diameter (in microns, µm). It has been
modified from a
similar one constructed by
S. B. LeValley (Grades
and Lengths of Grease Wool)
which may be found in its original form at the website of the
Colorado State
University Extension.

Classification |
Fiber Diameter (µm) |
|
Fine |
< 17.70 thru 22.04 |
|
Medium |
22.05 thru 30.99 |
|
Coarse |
31.00 thru 36.19 |
|
Very coarse |
36.20 thru > 40.20 |

A cursory microscopic examination of fibers
taken from the ewe lamb,
Hester (full Shetland),
showed that fibers from her fleece ranged
form FINE (18.75 µm) to VERY COURSE
(50.0 µm).
The majority of fibers
however were classified as FINE and MEDIUM. You can
expect a similar
range and average fiber distribution in all of our fleeces. Fiber
diameters we have
measured and
reported here are the same as those
reported for the finest Merino wool.
Furthermore, our average
fiber
diameter puts Pairodox fleeces well within the Merino class. The
table below compares the
fiber diameters ic of a number of
wool breeds. It was modified from
one found at
Gleason's Fine Woolies Ranch.
