The set of yarn found in every fabric woven on the loom and running parallel to the selvage. The warp is stretched in parallel lines in the loom and certain parts of it are alternately raised and depressed at every pick, allowing the shuttle to pass between with the weft. The warp can be of the same size as the weft or of higher or lower count.


The yarn that runs from selvage to selvage at right angles to the warp in woven fabric.

Warp Yarn

Yarn adapted especially for use as warp. It is often stronger and generally a higher number of turns of twist per inch than filling yarn.
