Warp and weft

In the manufacture of cloth, warp and weft are the two basic components in weaving to transform thread and yarn into textile fabrics.

[2][3] In the 18th century, the Industrial Revolution facilitated the industrialisation of the production of textile fabrics with the "picking stick"[4] and the "flying shuttle", which latter was invented by John Kay, in 1733.

[5] The warp is the set of yarns or other things stretched in place on a loom before the weft is introduced during the weaving process.

However, improvements in spinning technology during the Industrial Revolution created cotton yarn of sufficient strength to be used in mechanized weaving.

Many South American cultures, including the ancient Incas and Aymaras, employed backstrap weaving, which uses the weight of the weaver's body to control the tension of the loom.

In computing, a warp is a term for a block of parallel threads executed on a GPU or similar SIMD device.
