What is meant by "weft" in the context of fabric?

In the context of fabric, "weft" refers to the direction across the width of the fabric. When fabric is woven, it consists of two primary threads: the warp and the weft. The warp threads run lengthwise, creating the foundation of the fabric, while the weft threads are woven in and out across the width of the fabric, filling in the gaps between the warp threads. This interlacing of the weft with the warp results in the creation of the textile.

Understanding weft is crucial for various applications in fabric manipulation, and it plays a significant role in determining the texture, drape, and overall characteristics of the finished fabric. Different weaves can yield different fabric properties, such as strength and flexibility, which are important factors in industries such as aviation, where fabric is used in various components.
