warp definition
Warp and weft in plain weaving. In weaving, the woof (sometimes weft) is the term for the thread or yarn which is drawn through the warp yarns to create cloth. Warp is the lengthwise or longitudinal thread in a roll, while weft is the transverse thread. A single thread of the weft, crossing the warp, is called a pick. Terms do vary (for instance, in North America, the weft is sometimes referred to as the fill or the filling yarn). The weft is a thread or yarn usually made of spun fibre. The original fibres used were wool, flax or cotton. Today, man-made fibres are often used in weaving.
