1 Skin Wools
These are the product of the fellmongering industry as carried on in the Colonies, on the Continent, and in this country to a smaller extent. They consist of the wool removed from the skins of sheep slaughtered for mutton purposes. Many of these " skin " wools are of excellent quality; but large quantities, through unsatisfactory treatment during separation, and because of the absence of sorting, and neglect in skirting, picking, etc., are only useful for medium and low-class goods. Such wools lack spinning property, have a harsh handle, and do not mill and dye in the manner of the " fleece " wools. " Skin " wools are of the following types: - (1) Sun-dried and removed from the skin by a process of sweating; (2) separated by chemical agency, chiefly by sodium sulphide; (3) sliped from the skin after fibre separation through the application of lime (see slipe). Mazamet, France, is a great centre of the fellmongering industry, and a big business is done. Wools that are often of excellent quality and colour are taken from skins collected from all the principal wool-growing parts, and forwarded to all the important manufacturing centres through agents. Wools of Class 2 are largely the product of Colonial fellmongering stations in which the industry is of more recent growth. The system employed is the sodium sulphide process. Sodium suphide has the property of destroying the epidermis of the skin while improving the quality of the pelt. A 10 per cent solution of sodium sulphide will dissolve wool completely in 15 minutes. After washing, the skins are painted on the flesh side with thick paint of sodium sulphide. The skins are allowed to lie overnight, and the roots of the wool become loosened, the hair bulbs being destroyed, after which the wool is readily pulled by hand. -
2 British Wools
These are classified as: - (1) Lustres; (2) Demi-lustres; (3) Downs; (4) Special wools; (5) Half-breds. They are divisible into two chief sorts - long wools and short wools. The long wools include the Lustre and Demi-lustre wools, and the short wools comprise Down wools and Special wools. Lustre Wools are Lincoln, Leicester, Notts and Yorkshire. Demi-lustre Wools are Border Leicester, Cotswold, Romney Marsh, Roscommon, Wensleydale and Devon. Short Wools include the Down Wools, Special Wools and Half-breds. Down Wools are Southdown, Shropshire Down, Suffolk Down, Oxford, Hampshire, Wiltshire and Dorset Downs. Special Wools are Cheviot, Herdwick, Blackfaced, Welsh and Shetland. Half-bred Wools are North, Scotch Cross, South Ireland and others. There are also the " Skin Wools," which are comprised of wool removed from the skins of slaughtered sheep (see skin wools). A description of each type of wool is given under its name. -
3 Brushed Wools
This term is only applicable to pulled wools, or skin-wools, from the scrubbing or brushing process, which removes burrs, sand, dirt, and other foreign substances from the fleeces. This brushing process takes place while the wool is still a part of the pelt and are machine-brushed while on the pelt.
