describe briefly,how wool is obtained from sheep and processed to make woollen yarn.
Answers
Explanation:
the process of obtaining the wool from sheep is known as shearing . shearing is the first step to produce fibre into wool. it is removal of the fleece along with the thin layer of the skin. ... once the dying process in completedthe fibres are straightened combed and rolled into yarn.
Answer:
Greasy wool, also known as raw wool, is the unprocessed fibre harvested from the sheep during shearing. The greasy wool is classed (graded) based on fibre diameter, vegetable matter, staple strength, staple length, colour and potential yield.
Scoured wool is the term given to greasy wool that has been washed to remove contaminants, such as dirt, dust, sweat (suint), some vegetable matter and wool grease. The wool grease is recovered and from it lanolin is extracted and used in products such as cosmetics.
Carbonised wool has undergone an additional cleaning process (carbonising) to remove vegetable matter, such as seeds, burrs and grass. Carbonising is only used for wools that have large amounts of vegetable matter and the wool is only used in the woollen processing system, not the worsted processing system.
Top-making is unique to the worsted processing system and comprises three steps: carding, gilling and combing. Top-making turns the scoured wool into a 'top' or combed sliver — a collection of aligned fibres, without twist, ready for spinning into yarn.
