What type of fabric typically uses yarn dyes for producing patterns?

Yarn-dyed fabrics are created by dyeing the yarns before weaving them into fabric. This technique allows for intricate patterns, as the different colored yarns produce a distinct design once woven together. Among the options provided, plaid fabric is particularly well-known for utilizing yarn dyes because its designs are made up of multiple colored threads, creating the characteristic checks and stripes.

In contrast, denim, while it may also involve dyed yarns, is primarily woven with indigo-dyed yarn on one side and white yarn on the other, producing a solid texture rather than a pattern. Printed fabrics involve the application of dye on the fabric's surface rather than in the yarn, and canvas is often used for heavy-duty purposes without patterns relying on yarn dyeing. Hence, plaid stands out as the correct answer due to its dependence on yarn-dyeing techniques to achieve its recognizable designs.
