Weaner and hogget wool is finer and generally more valuable than the wool from older sheep. Most wool between 11.5 and 24 microns in fibre diameter is made into clothing. The remainder is used for other textiles such as blankets, insulation and furnishings.
Steel wool burning in air. Steel wool is commonly used by woodworkers, metal craftsmen, and jewelers to clean and smooth working surfaces and give them shine. [3] However, when used on oak, remaining traces of iron may react with tannins in the wood to produce blue or black iron stain, and when used on aluminum, brass, or other non-ferrous metal surfaces may cause after-rust which will dull ...
The finer the wool, the more hanks could be spun: from a pound of "62s," for example, sixty-two such hanks could be made. [1] Spinning counts range from about 32s for coarse carpet-wool to over 80s the finest wools. The Bradford System is widely used among shepherds and breed associations.
Wool straight off a sheep is known as "raw wool", "greasy wool" [8] or "wool in the grease". This wool contains a high level of valuable lanolin , as well as the sheep's dead skin and sweat residue, and generally also contains pesticides and vegetable matter from the animal's environment.
The surface of woven fabrics is often roughened with a raising card to create a softer feel, higher volume and greater thermal insulation [11] Vicuña wool is considered the rarest and most expensive legal wool in the world; in 2010, raw wool traded for about 7-15 dollars per ounce. [12] The sorted and spun yarn trades at about $300 per ounce.
The S numbers originated in England, [4] where the worsted spinning process was invented and arose from the worsted yarn count system for stating the fineness of yarn. The worsted count (also known as the Bradford count) was the number of 560-yard (510 m) lengths (hanks) of worsted yarn that 1 pound (0.45 kg) of wool yields. [5]
The spun thread was very uniform and fine. Some iron age fabrics also had patterns of stripes woven in. The finer fabric has been attributed to the development of breeds of sheep with finer wool and less kemp. [50] Other Iron Age fabrics from northwestern Europe have been found on bodies preserved by the anaerobic and acidic conditions of peat ...
Longer (more than 3 in or 76 mm) and finer wool yarns are used in fine worsted materials, and coarser and short-staple yarns (1–3 in or 25–76 mm) produce woolen materials. Worsted fabrics are smoother and more expensive. [19] [20] [21]
