 Raw
Fleece
Fibrecrafts fleece are individually checked for breaks,
britched and skirted, and any poor quality wool removed before
sale. They are sold complete where applicable and are non-repeatable,
we therefore recommend that you buy sufficient amounts for
each project. Fleece from the same flock can differ from fine
through to coarse and we endeavour to match your needs as
closely as possible. To place an order for fleece and to discuss
your requirements, please telephone: 01483 565800 or email
us with your enquiry.
Whilst we remove all heavily soiled material before supply,
fleece is the product of a sheep’s life out of doors.
You are therefore advised to cover cuts and abrasions while
handling fleece, and wash well afterwards. The risk of infection
is very small, but it is advisable not to let small children
handle unwashed fleece. A current tetanus immunisation is
prudent.
- First wash the fleece to remove soil and grease. Synthrapol
scouring agent is very effective for degreasing the fleece
and can be used with cold water to avoid the risk of felting
finer fibres. Allow to dry thoroughly.
- Use either hand carders, combs or a drum carder to card
the fibres into sliver ready for spinning or feltmaking
(see fibre
preparation products). Carding opens the fibre
mass and aligns the staple along the length. Commercially
the output from the carder is next assembled into a roving.
At this stage it contains a wide range of fibre lengths.
- The roving is combed into a 'top' for spinning into a
worsted yarn. This is the most common form in which wool
is sold.
 Prepared
Wool Tops
These are wool fibres that have been washed and carded into
a roving. The fibres are first prepared as above so that the
tops are consistent in their staple length and count. The
Bradford
count of fibre fineness is commonly used in the
UK to define a wool top: the higher the count, the finer the
top. The staple length should be consistent and defines the
ease with which it can be hand spun and the style of yarn
which can most easily be made. The images show Blueface Leicester
top and a skein spun from the fibre.
 Where
wool tops are a blend of natural coloured fibres there is
always a range of colours within the mix, commercially known
as 'jitteriness', and it is not possible to maintain a precise
colour match between batches. You are advised to buy all the
fibres for one project at the same time so that is comes from
the same blend. Dyed
Merino wool tops are batch dyed from white stock,
and are not blended. The colours are consistent and repeatable.
All fibres, and particularly wool, absorb and lose moisture.
As a result all weights of fibres supplied can vary by up
to 10% from the nominal.
Selecting Wool Fibres for Feltmaking and Spinning
Felt can be built in many ways using wool fibres as the
base (learn
how). However it is important to make sure that
you are using the correct quality of fibres. Too coarse a
fibre prevents felting; fibre below 56's Bradford count will
not felt easily. Lustrous, fine fibres felt quickly and reduce
the time for working the design into shape.
 Heavily
dyed fibres do not felt easily and black can be a particular
problem unless special dyes are used.
With all these points in mind, a range of undyed
and coloured
wool fibres are available from Fibrecrafts for
feltmakers and spinners. The Merino
Wool Tops offer a Bradford Count of 60 providing
a fibre which will felt readily and can also be spun into
yarn for garments which do not turn into felt at the first
wash! The fine black wool has been specially and carefully
dyed for Fibrecrafts to retain a good felting performance
and is excellent for fine woollen spinning.
Commercial wool tops can become compacted by the time they
reach you. There is a quick way to open them up which will
make drafting much easier. This applies to all processed fibres.
Grasp the sliver at one end, with your hands about 8 inches
apart, further for the long staple breeds such as Teeswater,
and gently draw the sliver four or five times until the fibres
start to 'give' and slip past each other. Do not pull so much
that the sliver thins or draws apart. Move your hands along
by two inches and repeat the procedure.
Here is a useful link from the Department
Of Primary Industries, Victoria, Australia which
explains a little more about wool properties and production.
