Which term describes threads that are made by twisting fibers together?

The term that describes threads made by twisting fibers together is "yarns." Yarns are the essential building blocks of textiles and are created through the spinning process, where different types of fibers, such as cotton, wool, or synthetic materials, are twisted together to form a cohesive strand. This twisting action not only helps to bind the fibers but also imparts strength and texture to the resulting thread.

Fabrics, on the other hand, refer to the textile material made by weaving or knitting these yarns together. Strands are a more general term that might not specifically describe the process or product of yarn-making. Wools refer to a specific type of fiber, typically sourced from sheep, and would not accurately describe the broader category of twisted fibers. Hence, yarns is the most precise and relevant term in this context.
