Pattern

Pattern is the way a fabric (e.g., fiberglass fabric) is woven. Plain weaves are the least expensive and least pliable, but they hold together well when cut. Frequent crossings of the threads reduces the strength of the plain weaves compared to other patterns. Satin and Twill weaves are highly pliable and stronger than plain weaves. In a Satin weave, one filling yarn floats over three to seven other warp threads before being stitched under another warp fiber. Threads run straighter much longer in this weave, maintaining fiber strength. Twill weaves are a cross between satin and plain types, and have a herringbone look.
