Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia[2]) is the sum of techniques, skills, methods

Silkworm Larva and Cocoon
The silkworm larva attains a maximum length of 7.5 cm (about 3 in). It pupates over a 45-day period within a cocoon made of one continuously wound silken thread. When straightened, each thread can reach lengths of 900 m (3,000 ft). Silkworms have been cultivated for their silk in Asian countries for centuries.
T he principal component of hair, wool, and fur is the protein keratin. Individual hairs may be as long as 91 cm (36 in) but are usually no more than 41 cm (16 in). Thus, fibres of hair and wool are not continuous and must be spun into yarn if they are to be woven or knitted into textile fabrics, or they must be made into felt. Any hair fibre can legally be marketed as wool or bear the common English name of the animal from which it was gathered—for example, camel's hair.


Dall Sheep
Dall sheep, sometimes called thin horn sheep, inhabit cliff regions in Alpine and Arctic tundra areas of Alaska and northern British Columbia. Related to the musk ox and the mountain goat, these sheep can have either black, grey, or white coats, depending on the subspecies.
The principal hair fibre used to produce textile fabrics is sheep's wool. In wild sheep, the wool is a short, soft under layer protected by longer, coarser hair. In domesticated sheep bred for their fleece, the wool is much longer. Yarns made of wool are classified as either woollen or worsted. Wool fibres less than 5 cm (less than 2 in) in length are made into fuzzy, soft woollen yarns. Longer fibres are used for the smoother and firmer worsted yarns. Naturally crimped wool fibres produce air-trapping yarns that are used for insulating materials.

Domestic Sheep
The domestic sheep, probably the most widespread species of domesticated animal in the world, is most likely the descendant of the mouflon from the Middle East. The domestic sheep is closely related to wild species of sheep such as the American bighorn, thin horn, and snow sheep.
Other animals used as sources of hair fibres for textiles include camels, llamas, alpacas, guanacos, vicuñas, rabbits, reindeer, Angora goats, and Kashmir (or cashmere) goats. Fur fibres from animals such as mink and beavers are sometimes blended with other hairs to spin luxury yarns but are most often found as fur pelts. Horsehair and cow's hair are used for felts and are sometimes spun as yarn, particularly for upholstery and other applications for which durability is important. Even human hair has been spun into yarn and used for textiles.
