The grazier would decide on the extent of crutching: the rear of the sheep is almost always shorn, whereas wool around the face, ears, underside and pizzle may also be removed depending on the circumstances such as the weather, length of fleece, and amount of seed or other impurities present in the fleece and the underlying reason for crutching ...
Excelsior, or wood wool. Wood wool, known primarily as excelsior in North America, is a product made of wood slivers cut from logs. It is mainly used in packaging, for cooling pads in home evaporative cooling systems known as swamp coolers, for erosion control mats, and as a raw material for the production of other products such as bonded wood wool boards.
A distaff (/ ˈ d ɪ s t ɑː f /, / ˈ d ɪ s t æ f /, also called a rock [1]) is a tool used in spinning. It is designed to hold the unspun fibers, keeping them untangled and thus easing the spinning process. It is most commonly used to hold flax and sometimes wool, but can be used for any type of fibre. Fiber is wrapped around the distaff ...
Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [ 1 ] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation ), filtration , soundproofing , and hydroponic growth medium.
Wood wool boards and wood-wool layers in composite boards are generally manufactured using coniferous wood species, mainly spruce and pine. The wood logs are processed to make wood fibres of various widths, generally between 1mm and 3mm. After drying the wood, it is planed into long fibres in a wood wool machine.
Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar , or from plants, as in pine tar .
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants.It is an organic material – a natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression.
Crutching is the trimming of excess wool from the breech area, and the timing of both shearing and crutching is critical in reducing the amount of flystrike. Surgical procedures are also performed in the sheep industry to help prevention, one of which is controversial due to its invasive nature.
