Which type of weave has each filling strand going over and under each warp strand once?

The type of weave that has each filling strand going over and under each warp strand once is indicated by the plain weave. This weaving method creates a simple and straightforward pattern, characterized by its interlacing structure that alternates the filling (weft) and warp yarns. The result is a strong and durable fabric that is commonly used in various textiles, including cottons, linens, and some synthetics.

Plain weave is foundational in textile creation because it is versatile and forms the basis for many other weave types. It produces a smooth surface and can be used for different applications, from fashion to home textiles.

On the other hand, satin weave, twill weave, and complex weave follow different interlacing patterns that change the fabric's characteristics. Satin weave typically allows three or more warp threads to float over a filling thread, resulting in a shiny surface but less structural integrity. Twill weave involves a diagonal pattern which provides a more textured fabric but does not adhere to the straightforward over-and-under pattern of the plain weave. Complex weaves may include a variety of techniques that do not fit the standard definition of simple over-and-under structures.
