2Turning Yarn into Fabric Weaving: The process of interlacing one or more sets of yarns at right angles on a loom.Warp yarns: Yarns that run lengthwise in woven fabric.Weft yarns: Yarns that run crosswise in woven fabric.Show example of selvage edge in relation to ward and weft
3Turning Yarn into Fabric (cont.) Grain: The direction of the lengthwise and crosswise yarns or threads in a woven fabric.Bias: The diagonal grain of a fabric. The bias provides the greatest “give” or stretch in the fabric.Use example to show grain and bias.
4WeavingPlain weave: The simplest weave in which the weft (crosswise) yarn is passed over then under each warp (lengthwise) yarn.A basket weave is one variation, with the weft yarn passing over two and under two warp yarns each pass.Examples: Chiffon, seersucker, taffetaPlain weaveUse magnifying glass to examine examples of weaves.
5WeavingTwill weave: A weave in which the weft yarn is passed over and under one, two, or three warp yarns beginning one warp yarn back on each new row.Used for durability, this weave produces a diagonal design on the surface.Examples: denim, gabardineTwill weave
6WeavingSatin weave: A weave that produces a smooth, shiny-surfaced fabric resulting from passing the weft yarn over and under numerous warp yarns to create long floats.Examples: sateen, satinSatin weave
7Weaving Other weaves Pile weave—corduroy, velvet Dobby—dotted swiss, piqueJacquard—brocade, damaskLeno—fabrics with an open, lacy appearance
