wool

(wul),
The hair of the sheep; sometimes, when defatted, used as a surgical dressing.
Synonym(s): lana

wool

the natural fiber produced by the skin of domesticated sheep, characterized by its quality of felting together by virtue of its imbricated surface.

wool ball
black wool
inherited coat color in sheep.
wool blind
the state of having excess wool growth around the eyes to the point where the sheep is unable to see.
break in wool
see wool break.
carding wool
wool suitable for the woollen trade.
carpet wool
coarse low-grade wool, used in the manufacture of carpets.
wool classing
see wool classing.
clean wool
the basis on which the price of wool is set; scoured wool less charges and loss incurred in scouring.
combing wool
long-fibered wool suitable for processing in a combing machine. Used in textile manufacture, especially worsted.
colored wool fibers
naturally colored fibers in a fleece.
dead wool
wool plucked from a sheep which has been dead for some time; usually heavily contaminated and of little value.
dense wool
staples carrying many fibers per unit area of skin surface.
wool depigmentation
wool discoloration
see fleece rot, mycotic dermatitis.
doggy wool
unevenly or poorly crimped wool; found in old sheep.
wool eating
eating of rabbits' wool by other rabbits, or wool from garments by cats causes intestinal wool balls and obstruction of the gut. May be a manifestation of pica due to boredom.
wool fat
see lanolin.
wool fiber abnormalities
includes straight, steely wool, wool break, pigmentation, achromotrichia in black sheep.
wool fiber diameter
thickness of the fiber; wool is sold on the basis of the average fiber diameter of the wool in the lot as determined by a machine and quoted in microns (micrometers); a more sophisticated classification is made on the basis of the average fiber diameter and the variability of the diameter.
greasy wool
wool in its natural state, after removal from the sheep and before any commercial processing; contains yolk, suint, moisture, extraneous soil and vegetable matter.
wool hairs
the soft undercoat fibers in most cats and dogs, interspersed with the longer guard hair; the predominant fiber type in sheep.
hogget wool
first fleece from a 10 to 14 month old sheep which has not been previously shorn.
hunger fine wool
wool with a finer fiber diameter than expected for the sheep's age; caused usually by poor nutrition.
wool industry
includes sheep farming, shearing, wool sales, wool processing and fiber and fabric manufacture.
wool maggots
see cutaneous myiasis.
wool picking
pulling at the wool of another sheep. It may be a vice due to over-confinement, or to an unspecified nutritional deficiency. Biting of another sheep as occurs in rabies may be confused with wool picking but not for long.
plain wool
straight wool lacking crimp and character.
wool processing effluent
liquid effluent from wool processing; has been a source of infection with anthrax.
wool pulling
pulling by the sheep of its own wool, usually an indication of itchiness. See also psorergatesovis.
wool quality
the British standard for wool quality is based on the Bradford Spinning Count System and the wool qualified as to its Bradford Count. This originated in the 19th century and is based on the number of 560-yard worsted skeins that can be produced from one pound of clean wool; larger numbers mean finer wool.
wool rot
see fleece rot.
wool rubbing
the sheep rubs its fleece against a hard object. Usually an indication of itching caused by external parasites or to a systemic disease with manifestations in the skin. See also scrapie.
wool slip
alopecia of housed ewes that are shorn in winter. The wool is lost over a large area of the back. There is no systemic illness and the wool regrows normally. The cause is unknown but the condition appears to be related to a high level of serum corticosteroids.
straight-steely wool
wool sucking
a vice of cats, particularly Siamese and Siamese crosses, in which they suck or chew woollen objects. Believed to be an extension of sucking behavior.
tender wool
wool which will break during the combing process in manufacturing.
wool wax
see lanolin.
wool weight
see fleece weight.
wool yield
the percentage of raw wool that can be retrieved from processing in a state suitable for the particular type of production which is in hand, e.g. carpet making.

The following variables were analyzed: A) Pulp firmness: measured by Effe-GI penetrometer, 5/16 inch diameter, after collection of a small portion of epidermis, with two readings in each hemisphere (right and left), with results expressed in Newtons (N); B) Loss of fresh mass: samples were weighed on a Toledo-computagram scale, and the results were expressed as a percentage of fresh mass loss in relation to the initial mass of the fruits at harvest time; C) Juice content (incidence of woolliness or leatheriness): determined subjectively by pressing fruits between fingers and direct visualization, presence or lack of juice, and/or farinaceous juice.
Therefore, it is concluded that woolliness and leatheriness, two disorders that relate directly to pulp firmness in peaches, present distinct behaviors and are characteristic of the white pulp fruits.
Thus, it can be concluded that leatheriness has a direct connection to excessive loss of fresh mass and that the woolliness found in the white pulp cultivars cannot be related to loss of moisture but can be related to a lack of juice that is kept in the formation of pectic gels.
2004), in both woolliness and leatheriness fruit disorders, the loss of juice contents was a remarkable characteristic associated with low temperature intolerance.
The development of woolliness symptoms is accompanied by reduced rates of respiration, very low ethylene evolution (VON MOLLENDORFF; DE VILLIERS, 1988A; ZHOU et al.
On the same day of harvest (3 trays, each tray constituted a replicate) and on the 4th day of ripening (3 trays), the peaches were evaluated for woolliness incidence, pectolytic enzymes activities: exo-polygalacturonase (exo-PG), endo-polygalacturonase (endo-PG) and pectin methylesterase (PME); the respiratory rate and ethylene synthesis were monitored during 6 days of ripening.
On each day of evaluation, ten fruits were randomly removed from three trays to determination of woolliness incidence (WI).
The percentage data for the variable woolliness incidence were normalized according to the equation f(x) = arcsen [(x + 0.
The fruits were cut into two halves and the woolliness incidence (WI) was determined visually in both sides (adapted from FERNANDEZ-TRUJILLO et al.
The percentage data for the variable woolliness and decay incidence were normalized according to the equation f(x) = arcsine [(x + 0.
Woolliness is one of the physiological symptoms of postharvest quality loss in 'Douradao' peaches and it was affected by the MAP treatments.
Packages of 30 and 75[micro]m LDPE films were ineffective for reducing woolliness during cold storage, due an atmosphere similar to the air surrounding the fruit and an atmosphere with very low oxygen concentration, respectively.
