What type of yarn is created by twisting together short man-made fibers, often resulting in a fuzzy texture?

The correct choice is spun yarn, which is made by twisting together short lengths of fibers. This method of construction typically leads to a fuzzy texture, as the fibers can protrude slightly from the yarn itself. Spun yarns are known for their softness and warmth, making them particularly popular in the production of knitwear and other garments where comfort is important.

In contrast, filament yarn is created from long continuous strands, which results in smoother and often shinier textures. Textured yarn can refer to a variety of constructions that may not exclusively involve short fibers, as it can also encompass processes that create bulkiness or a distinct surface feel. Warp yarn refers specifically to the yarns in the warp of a woven fabric, which run lengthwise and are not necessarily characterized by a fuzzy texture. Understanding these distinctions helps clarify why spun yarn is the appropriate answer in this context.
