Weft, английский
- Water-elimina- tion fourier transform
- See waft.
- [1] in common english usage, the thread or yarn which is shuttled back and forth across the warp to create a woven fabric (from the old english wefan = to weave). [2] a 17th and 18th century naval term referring to a flag or ensign, lightly rolled up lengthwise and hoisted at various positions as a signal conveying orders to the fleet. for example, prince rupert’s 1666 fighting instructions anticipate nelson’s famous signal “engage the enemy more closely” by saying: when the admiral of the fleet makes a weft with his flag, the rest of the flag officers are to do the like, and then all the best sailing ships are to make what way they can to engage the enemy. however, the import of a weft was not fixed and, seven years later, orders issued by the duke of york gave the signal a different meaning: upon discovery of a (hostile) fleet and receiving of a signal from the admiral, which is to be the striking (lowering) of the admiral’s ensign, and making (hoisting) a weft, such frigates as are appointed ... are to make sail and to stand with them (the enemy), as nigh as they can conveniently, the better to gain knowledge of ... what position their fleet is in; which being done the frigates are to speak together and conclude (agree on) the report they are to give.... by the late 18th century navies had developed better signaling systems, but the weft continued in merchant service—where it was also known as waft or weapons 356 waif—to describe any piece of cloth or clothing, or a rolled and knotted flag, flown as a signal. different positions told which message applied. for example, a weft at the ensign staff signified “man overboard,” at the peak it said “let’s talk,” and at the masthead it was the “recall” for small boats.
- Three basic weave structures are created: plain, twill and satin. all other weaves, no matter how intricate, are derived from these three structures.
- The yarns running horizontally in a woven fabric, crossing the warp from selvage to selvage; also called filling yarns or picks.
