This is the simplest weave, where each weft thread passes alternately above then below a warp thread. It is a blocked fabric, not very deformable given the density of the intersections made. The fabric has neither place nor reverse. This weave is widely used for clothing and furnishings under different names depending on its composition. We find in particular: - Taffeta: fine fabric with tight warp threads, originally in thread-dyed silk - Chiffon: very fine, light and transparent fabric, thanks to the use of very fine and widely spaced yarns in both directions - The batiste: fine and light white fabric, originally made of linen yarn - The cheesecloth: fabric with slightly tight threads, supple and light in appearance- Organdi: spun fabric obtained with overtwisted threads- Other names: cretonne, poplin, crepe, voile, oxford, percale, gros de tours…Derivatives are found: basket weaves, reps and canelés
