The process of forming fabric on a loom by interlacing the warp (lengthwise yarns) and the filling (crosswise yarns) perpendicular to each other. The filling is fed into the goods from cones, filling bobbins or quills, which carry the filling yarns through the shed of the loom. The filling may also be inserted into the material without the use of a shuttle, as in the case of a shuttleless loom. The three basic weaves are Plain, Twill, and Satin. All other weaves, no matter how intricate, employ one or more of these basic weaves in their composition. Variations on the basic weaves make a variety of different fabric surfaces and fabric strengths.
