CLASSING, RECORDS, BAGGING AND WEIGHING
By Linda Wendelboe
Classing each fleece and keeping written records of the fleece production for each Shetland can be very
useful. These processes are effective for
marketing fleeces at a premium and also for improving breeding decisions for quality fleece production.
The staple length (relaxed) and style (crimpy, wavy, or straight) of the
locks/staples should be measured and recorded. Handspinners often want to match
a staple length and style to their project. In commercial processing, mill
requirements and capabilities vary
from mill to mill. Fleece 3-6" is usually suitable for processing into a worsted
style yarn. Fleece over 6" may have to be processed by a specialty mill or may
have to be cut by a mill in a special machine before processing. Fleece from
2–4" is usually suitable for processing into a woolen style yarn.
"Hand" or "handle" is also very important
in marketing to hand spinners or in choosing the end use for the fleece.
Noting the feel of the fleece can be very helpful. Some sensations
that may be apparent are: softness (different from fineness), stickiness,
dryness, silkiness (a smooth feeling), resistance to compression, ease of
drafting (pulling the staple apart from the tip or butt end).
Fineness is a characteristic that takes experience
to
measure subjectively but recording some assessment is important. If
you have a fleece reference binder containing samples that have been
histogram tested, you can compare to that. Using a linen pick, loupe
or 10x magnifying glass may be helpful. Put dark staples on a light
background, put light staples on a dark background for examination.
There is no need to try and estimate micron counts, if you do not have the
experience for this. Noting Finest, Fine, Medium, Coarse and
Coarsest is a good start.
Any additional information such as animal name, age, length of growth period,
lustre, colour or fleece tenderness can be recorded along with
current micron count, if known.
The skirted fleece from each Shetland can be weighed; the weight and various
qualities of fleece for that Shetland added to the written record. The weight of
the collection bags, if weighed beforehand, can be deducted to determine the
shear weight of the fleece. This information is useful in tracking fleece growth
patterns and changes and in examining possible correlations between husbandry
practices and fleece production.
Any fleeces showing dual coat characteristics (containing a large percentage
of longer outer coat or secondary coarse fibre) can be improved by dehairing or
removing the hairier or coarser fibres. Some mills have dehairing facilities.
This can also be done by hand before processing. Do not place fleeces having
dual coat characteristics in with fleeces that are relatively free of the longer
hairier outer coat.
Shetland fleece can be stored in plastic bags for moderate lengths of time
but the bags should be left open for at least a few days to allow moisture to
escape. Long term storage is better in cloth or cardboard. Greasy fleece will
become rancid over time so washing fleeces that will be in long term storage may
be prudent.
