Вить, витии = 1) свивать гнездо; 2) наматывать.

jean (n.) (Твиль, саржа; одежда)
"twilled cotton cloth," mid-15c., from Middle French jean fustian "fustian (a type of twilled cotton cloth) of Genoa," the city in Italy, from Old French Jannes "Genoa," from Latin Genua (see Genoa). The plural form jeans became standard 19c.

twill (n.) (одежда, сотканная из параллельных диагональных линий)
"cloth woven in parallel diagonal lines," early 14c., Scottish and northern English variant of Middle English twile, from Old English twili "woven with double thread, twilled," formed on model of Latin bilix "with a double thread" (with Old English twi- substituted for cognate Latin bi-), from Latin licium "thread," of uncertain origin.

tweed (n.)
1847 (perhaps as early as 1831), a trade name said to have developed from a misreading (supposedly by London hatter James Locke) of tweel, Scottish variant of twill, possibly influenced by the river Tweed in Scotland.

И, причем здесь Генуя?
Точнее – «поведу». Вот такой переход «п» («б») - «f»(«в» - «v») - «d» - «t».
