Did You Know? Mean fibre diameter is a measurement in micrometres (microns) of the average diameter of wool fibres in a sale lot. Fibre diameter is responsible for 70-80 per cent of the greasy wool price over the long term. Fine and superfine wool production has increased as a percentage of the Australian wool clip. Australia dominates the supply of fine wool to the international trade, accounting for over 90 per cent of global production of Merino wool of 19.5 micron and finer. Global demand for finer wool has increased. Manufacturers and processors must source more fine wool to satisfy the global consumers' demand for lightweight garments with next-to-skin comfort, particularly in women's wear. (Source: AWI) |
The wool roller is critical to the final quality of
the wool clip. "Skirting fleece" removes inferior
wool, and then rolling the fleece ready for wool classing. Once
you know the fleece areas and are doing a quality job on the
table, the required speed to keep up with the rate of wool flow
will
come easily. Different skirting procedures
will be used for preparing superfine clips.
These requirements will be determined by the woolclasser.

Did You Know? Skirting Your Wool Fleece ( Skirting is the process of removing “junk” wool, stains, second cuts and vegetable matter (VM) from the wool fleece prior to processing it ~~ or offering it for sale. The skirting process is usually done by the shepherd after the fleece is shorn and requires a special skirting table with an open mesh top. The table must be large enough to lay the entire fleece out flat – cut side down, tips up and the head and tail ends identified. A skirting table may be made simply by the handy-man (many plans are available) OR purchased ready-made. The first step is to work around the fleece giving each part a light shaking. This allows most of any second cuts to fall through the mesh. ‘Second cuts’ are a fault in hand-spinning fleeces and, unless removed from the fleece, they will cause neps in carded wool. They’re caused by the shearer making a second pass over the sheep during shearing to give the shorn animal a neater appearance. The next step is to actually skirt the fleece: Pick a starting point, such as the tail, and work all the way around the fleece removing from 2 to 4 inches of wool all the way around – exactly how light or heavy of skirting is needed depends entirely on the cleanliness and quality of the fleece. Remove any tags (dung or stained wool) at the tail, skirt away the lower leg wool and evaluate the britch (upper leg) wool for kemp (hair fibers) and skirt those off. Then, skirt away any belly wool if the shearer has not tossed this aside when shearing – some shearers will do this, some won’t. Next, skirt away the front leg wool and the head wool. Then work down the other side the same way, back to the tail. Now, look at the fleece. Are there any stains? If so, skirt away those areas. Look for areas with a lot of VM and skirt those areas away too. Finally, check the fleece for tippiness and for wool breaks. Tippiness is caused mainly by weathering and is most likely to occur along the spine. Pull a small lock no thicker than a pencil and hold it by the butt (cut) end. Grasp the tip between the nails of your thumb and index fingers and give it a little tug. If the tip broke off, then the fleece is tippy. Skirt the tippy area away – the tips will break off when the fleece is carded and form neps in the carded preparation. Wool breaks are also easy to detect. Look at a lock of the fleece – is there an area in the staple length that looks thinner? Take a small lock of fleece and firmly grasp it by the cut end with one hand and the tip end in the other. Give it a tug. Does it come apart? To confirm that there is a break, take a thin lock, maybe half the diameter of a pencil, grasp it in both hands, hold it up to your ear and pull. Do you hear crackling or ripping sound? If so, that’s a wool break. This would not be a good, sound fleece.

Duties and Tasks
Pick up the fleece after it has been removed from the sheep and throw it onto a large table for 'skirting' (process to remove stained or coloured pieces and skin from the wool)
Remove inferior and stained wool from fleeces as directed by a wool classer
Remove fribs and sweats and place in appropriate bins
Remove short crutch wool and wiggings and place with locks
Remove wool carrying vegetable matter under wool classer supervision
Skirt around the fleece using the thumb, index finger and middle finger.
Fold over the edge being skirted as it is finished. This identifies where the fleece has been skirted and turning the edge in allows the wool roller on the opposite side of the table to check for any fribs that may have been missed.
Roll fleece according to wool classer’s direction. The fleece will usually be rolled form the breech to the neck end, with the aim of presenting the shoulder consistently to the woolclasser.
Check for skin pieces while rolling. Apply the same method for removing brands to removing skin pieces. Grab a hold of the skin piece, twist it and pull out ensuring that you are only grabbing skin.
Grade wool that has been skirted off fleeces
Roll the fleece into bundles and pass it to a wool classer for classing
Seek feedback on accuracy of skirting and fleece to skirtings ratio
Working conditions
Wool Room
Sufficient space is
required in the wool room to enable the wool fleece to be safely and effectively skirted and classed. There is a risk of a range of injuries due to collision with fellow workers and contact with shed machinery - influenced by the amount of space available. In addition, working on small wool tables which are not designed for the size of fleeces can result in back strain. Uneven floor surfaces increases the risk of trips, slips and falls, while sharp edges and protrusions used to support wool packs or wool bins, pose a risk of cuts and puncture wounds to those working in this area. |
Modifications to improve the safety of the wool room may include: • Ensure that wool tables are large enough for the fleece and have enough room for wool rollers to work around the table without contact with shed machinery or other workers. • Ensure that the height of wool tables is appropriate for workers. • Slope the wool table toward the shearing board to facilitate ease and accuracy of throwing. • Remove protrusions on wool bins or cover with protective material. • Prior to each shearing, all boards should be inspected with worn and / or loose boards repaired. • Ensure there are enough shed hands to cope with the workload (Source: Australian Centre for Agricultural Health & Safety, June 2016) |
The Wool Roller has to remove the sweat locks and other processing faults present from the outer section of fleece under instruction from the woolclasser eg. stained, unusable, or undesirable portions of a fleece.
Along with the physical side of the wool room itself, there are other things that the wool roller has to be mindful of including:
Dags - Broken or dung-covered wool and other wastes that are swept from the floor of shearing areas
Fribs – Greasy pieces of wool found on the outer edge of the fleece
Vegetable matter (VM) – Any material of plant origin found in the fleece, such as burrs, stickers, chaff and seed heads
Lanolin – Wool grease; this substance is a secretion from the sebaceous glands of the sheep skin
You would need to be very careful
of your hand hygiene!
Education and training/entrance requirements
No education requirements however you will need to
get practice in wool rolling during your time as a Rousie and under the
guidance of the wool classer.
